The Relations Between Green Building Concept and Pro-Environmental Behavior in Vertical Housing
Authors: Rachmaniatus Syahriyah Dewi , Aryacitra Bhaskara Panji
Published: August 2019

Residential building in a post-occupation phase and building operations consume large amounts of energy and cause environmental degradation. To reduce the negative impact of energy consumption in residential building, green concept through occupant behavior (pro-environment behavior) is useful. Implementation of green concepts on buildings is expected to trigger the emergence of pro-environmental behavior. This study aims to analyze the correlation of green values in a residential building with the value of pro-environmental behavior, especially on student vertical housing. Based on purposive sampling (non-random/non-probability sampling), correlation analysis shows that the concept of green building has a high correlation with a significant value of <0.05 towards pro-environmental behavior. The application of the green concept in improving pro-environmental behavior can be made by considering three priority categories, namely the site development, energy efficiency, and the use of materials.

Authors: Hastuti Elis , Medawati Ida , Anggraini Fitrijani
Published: August 2019

The acceleration of improved sanitation access in specific urban areas can reduce water-borne diseases and the degradation of water resources. In this paper, the development of technology of wastewater infrastructure in some specific urban regions with an ecosystem approach will be analyzed based on some practical research. The ecosystem approach is analyzed with integrated biophysical and social factors for improved wastewater system; it includes the tidal area, coastal area, and urban water sensitive area. The system of wastewater treatment has certain design criteria to be adapted for specific areas and upgrading the treatment process based on the ecosystem characteristic, community awareness of sanitation and some best practices. The design criteria of wastewater treatment consider the process of environment approach, pollutant transformation target, and the configuration of the processing unit. The option of treatment technology at an individual, communal or settlement scale depends on biophysical factors in each area. This condition can achieve 80-95 % organic removal, 30-70 % nutrient removal by biofilm absorption or phytofiltration. Challenges and social constraints at each selected technology development have an influence on the sustainability of infrastructure in achieving health requirements and the standard of effluent for watercourse or water reuse.
Urban Green Infrastructure Framework for Housing Climate Resilience
Authors: Araaf Tauhid Fahmyddin
Published: August 2019

Climate change is affecting urban areas by increasing the intensity and frequency of climate-related disasters such as flooding, sea level rise, drought, etc. The trend is expected to rise significantly without proper intervention. Urban housings as the concentration of people and economic growth are the most impacted. This condition calls to study green infrastructure/GI strategies as a more sustainable way than the conventional. Such GI approach not only mitigate and adapt the impacts but also improve the urban climate resilience, particularly in the housing sector. Therefore, this study aims to propose a conceptual framework to integrate the elements for the implementation of GI for mitigating and adapting climate impact for urban resilience improvement. This study identified elements to employ GI for housing climate resilience: public awareness; land use and development regulation; land and property acquisition; environmental management plan; housing strategy; fiscal and taxation; and governance. This framework is a new tool for scoping and assessing urban housing vulnerability to climate change by helping stakeholders to systematically consider the benefit to introduce GI scheme in respective efforts.

Published: August 2019

This study aims to determine the indoor comfort temperature before sleep and after wake up in air-conditioning (AC) mode with different adaptive cooling strategies. Two units of guest rooms on the university campus were used with a total of 20 participants. The arbitrary-controlled AC setting (case 1) and control of thermostat setting by 3∘C higher than case 1 with installing of cool bed padding (case 2) were employed as cooling strategies in this study. The measurement parameters were indoor and outdoor air temperatures, globe temperature, relative humidity, air velocity, and AC electricity consumption. The questionnaire survey has also been distributed twice a day for “before going to bed” and “after waking up” during measurement simultaneously. It was observed that thermal sensation vote (TSV) indicated for both cases were within -1 ≤ TSV ≤ 1 and respondents might accept the present condition for both cases. Mean thermal preference (TP) in both cases either “before going to bed” and “after waking up” was found mostly close to “0 no change” (0.1 ≤ TP ≤ 0.3) for all cases. Overall comfort (OC) ranged between 4.7 and 4.9 for both cases, indicating for “comfortable.” However, air movement sensation (AMS) shows respondent felt weak airflow inside the room for all ventilation strategies. The skin moisture sensation (SMS) shows value pointed to neutral feeling for all cases. The comfort temperature obtained by Griffiths’ method was approximately 24∘C and 25∘C that for case 1 and case 2, respectively. Meanwhile, most of the respondents experienced calmness during sleeping and satisfied with their sleep in both cases. Sleep efficiency index (SEI) shows case 2 was higher rather than case 1. It seems the second adaptive cooling strategy might effective for reducing AC energy consumption by about 32% and increase 2% of SEI without affecting respondents’ thermal comfort.
The Effect of Urban Geometry on Low-Carbon Development in Desa Sruni, Wonosobo
Authors: Akbar Ivan , Donny Koerniawan Mochamad
Published: August 2019

Urban geometry is one of the important issues in creating a low-carbon sustainable dwelling area. Open spaces located in the settlement area is one of many elements that help to balance the energy exchange process that occurs in the land surface. The balance between energy absorption and emittance can prevent the occurrence of Urban Heat Island (UHI) which increases air temperature. Desa Sruni is one of the high-density villages located in Wonosobo, Central Java. The village is dominated by settlements that almost reach 60% of the area while the rest is impervious surface used for circulation and vacant lands. This study aims to find the effect of urban geometry changes on urban climatic conditions in Desa Sruni. The research is carried out by using a quantitative method with the help of Envi-met to find the value of some variables such as Sky View Factor (SVF), Air Temperature (Ta), Mean Radiant Temperature (Tmrt) and Wind Speed (Ws). The outcome of this study can be used as a further reference to create a design recommendation on low-carbon development in Desa Sruni.

Published: August 2019

Riparian is undefined government land and can be converted to other utilization. Riparian areas have natural connections throughout the watershed; they are particularly sensitive and often degraded by human use. One of them is the informal settlement, such as the residential areas in the Ciliwung River riparian which changed the land function from a conservation area. This research conducted in three sites of the Ciliwung River riparian section that is represented by the upper part (Kelurahan Katulampa); middle part (Kelurahan Babakan Pasar); and the lower part (Kelurahan Kedunghalang). The purposes of this research are: 1) to analyze the riparian settlement yard in upper part, middle part, and lower part, 2) to figure out people’s motivation for the management of land yard, and 3) to calculate the potential of land as water catchment areas and to support household-scale agricultural production. The remaining of land in the informal settlement is upgraded to fulfill the riparian function and to improve local people’s welfare. Data were obtained by doing a literature review on previous research with a systematic literature review method; by analyzing the agroforestry land use; and by analyzing plant production. Plants production for agriculture concept in pekarangan in Ciliwung River riparian, Bogor Municipality have high potency. The result of the study of all sites is combined into an integrated agriculture concept as an alternative to efficient land use. These concepts offer some benefits from the ecological, social and ecological aspect. It can be used to convince the community for improving their welfare, as well as raising public awareness about the primary function of the riparian landscape.

Authors: Herma Dwidayat Kunthi i , Samyahardja Puthut
Published: August 2019

The most population density in RW 08 Cigugur Tengah reached 1000 inhabitants/ hectare. However, it does not mean an area is said to be slum if it is only seen based on its population density. Another factor is the availability of adequate infrastructure and facilities and building regularity. As in RW 08, there is a land in the middle of a densely populated area with an area of 840 m2 and inhabited by 40 peoples who have a family relationship. The land was originally owned by the family which subdivided for its descendants. In this case, the minimum space requirement is achieved; however, in terms of infrastructure, facilities and building regularity are not achieved. A new strategy is needed to resolve this problem without relocation, Therefore, the objective of this research is to identify the appropriate local restriction or local criteria which used in the planning of housing design concept in criteria before designing or revitalizing the slum areas inhabited by the family and the environment surround in the densely populated area. This research used a quantitative and descriptive method. The results show that the specific characteristics such as geographical conditions and the characteristics of the community greatly influence the consideration in determining the appropriated housing design concept.

Published: August 2019

The present study is intended to evaluate an outdoor thermal comfort at two universities campus in Malaysia. Field measurement and questionnaire survey were conducted simultaneously to assess the microclimatic condition and pedestrian thermal sensation. A total of 3033 samples were collected at seven different sky view factor (SVF) values that range from 0.2 to 0.9. The physiological equivalent temperature (PET) was estimated to evaluate outdoor thermal comfort. It was observed that at a highly shaded area (SVF < 0.35) the respondent’s thermal sensation vote (TSV) are neutral (> 25%), acceptable for thermal acceptance vote (TAV) (> 50%) and no change (> 50%) for thermal preference vote (TPV). For moderate shaded (0.35 ≤ SVF ≤ 0.70) TSV was voted as hot (> 25%), acceptable for TAV (40%), and prefer slightly cooler for TPV (>50%). For less shaded area (0.70 < SVF ≤ 1), TSV was voted as hot and very hot (> 25%), acceptable for TAV (>40%) and prefer slightly cooler for TPV (> 40%). Moreover, the PET value increases simultaneously with the increase of SVF. Results thus suggest that at any given activities such as sitting, walking, and standing also caused effects slightly on the way people thermally perceive it during the on-campus daytime.
Sub-Neighborhood Housing: An Alternative to Arrange Slums Areas. The Case Study of Kampung Cigugur Tengah, Cimahi
Authors: Samyahardja Puthut , Pauzi Rachman Arip
Published: August 2019

The ongoing slum upgrading program is encouraging to find alternative ways of slum area arrangement that better suit local characteristics. Studies indicate that managing slums in the size of a neighborhood has difficulties in consolidating private assets into communal assets because of particular social cohesion. A neighborhood in a slum area can be split into sub-neighborhoods that can be handled uniquely, and it is more manageable to share shelters and facilities assets because of immediate neighbors cohesion which bonding in a sub-neighborhood area. This sub-neighborhood segmentation is applied as the basis for the residential planning and design of slum dwellings in Kampung Cigugur Tengah, Cimahi City. Planning and designing processes adapt a linear process approach that is supported by contextual models to get special needs from the community. Because of the certainty of land tenure and the possibility of physical improvement of the environment, there is a tendency not to move from improved areas. Sub-neighborhood physical development plans and designs can increase the likelihood of successful implementation of slum improvement programs because of the simplicity of fund management and construction. There is relatively high attention to the design of sub-neighborhoods based on non-transferable asset ownership; the opportunity for increasing occupancy capacity and open space; and a better local environmental change.

Published: August 2019

Universitas Pendidikan Indonesia (UPI) is one of the favorite education facilities that attract students from other regions. This fact can cause an increase in the need for a living place near UPI. Limited availability of land and increasing land needs affect the quality of the settlements. The objectives of this research are 1) to identify and analyze the factors that affect settlement quality around UPI, 2) to analyze a settlement quality around UPI, and 3) to examine the possible linkage between settlement quality and the students’ learning achievement. The method used is data extraction from satellite imagery to obtain settlement quality parameters: settlement density, building layout, the width of settlement driveway, settlement location, settlement driveway condition, and the existence of vegetation. Another data sets were collected through questionnaires on the students’ learning achievement. This research shows that there is no strong correlation between the quality of settlements and the students’ academic performance. This is evidenced by the highest GPA points achieved by students who live in only moderate quality settlements.

Published: August 2019

Load profile of household air-conditioning (AC) and total electricity consumption is essential to increase the stability of the energy demand on the grid. Therefore, field measurements on time series data of total and AC electricity consumption from 20 households were conducted from March 2016 to August 2017. The questionnaire survey was carried out simultaneously to grasp the profile of each family. The average total daily and AC consumption were 14.5 kWh/day and 3.9 kWh/day, respectively. The average hourly electricity consumption for total was 0.6 kWh/hour, meanwhile for AC was 0.2 kWh/hour. About 20% of the total peak demand was contributed by the consumption of AC. The indoor air temperature was measured in the bedroom (BR) when AC was switched ON and OFF with an average of 27 ∘C and 29 ∘C, respectively. However, the indoor air temperature in the living room (LR) was 2∘C and 1∘C higher if compared to BR for both conditions. Based on the questionnaire survey, 92% of the occupants preferred a temperature setting below than the level recommended by the Malaysian standard i.e., 24 ∘C. These results might be beneficial to understand the occupant behavior of electricity demand in Malaysia for designing smart grid energy systems in the future.

An Efficient Electronic Checkbook Scheme with Mutual Authentication
Authors: Sertkaya İsa , Kalkar Öznur
Published: August 2019

In 1988, Chaum et al. introduced the idea of electronic check. Then, Pasupathinathan et al. tried to come up with an electronic checkbook scheme. However, their scheme requires signature for each e-check and is not considered as an e-checkbook. Later, three e-checkbook propositions are made by T.H Chen et al., Chang et al., and C.L. Chen et al. based on the scheme of W.K. Chen et al. Recently, Sertkaya and Kalkar showed that these three e-checkbook schemes are susceptible to e-check forgery and/or e-check manipulation attacks. They also proposed fixes for these schemes. Nonetheless, fixed versions also carry out drawbacks of the original schemes, like heavy hashing computations, time-synchronization issues, and multiple communication rounds. This study offers an efficient and secure e-checkbook scheme with mutual authentication.

Published: August 2019

Este artigo resultou de um projeto de pesquisa sobre a história da educação no Pará, e tem como objetivo principal compreender a concepção de educação da mulher para José Veríssimo. Para atingi-lo desenvolvemos uma pesquisa bibliográfica utilizando como fonte principal a obra “A Educação Nacional”, escrita em 1890, de autoria do escritor, jornalista e historiador literário José Verissimo Dias de Mattos. Entre os principais resultados do estudo, descobrimos que o papel atribuído à educação feminina se configurava como uma estratégia pensada pelos republicanos tendo em vista a construção de uma sociedade moderna e civilizada. Nesse sentido, as propostas de educação feminina de Veríssimo representaram avanços incontestes; entretanto, mesmo assim, a educação destinada às mulheres ainda se limitava a um benefício à gestão do lar e à formação dos filhos, além do apoio mais qualificado às iniciativas do marido, chefe da família.

Low-intensity Exposures via Luminescent Bioassays of Different Complexity: Cells, Enzyme Reactions and Fluorescent Proteins
Authors: Kudryasheva Nadezhda S. , Kovel Ekaterina S.
Published: August 2019

Current paper reviews applications of luminescence bioassays for monitoring low-intensity factors, namely, radioactivity of different types (alpha, beta and gamma), and bioactive compounds (humic substances and fullerenols). Luminescence intensity is taken as a physiological parameter of luminous organisms. High rates of luminescence response can provide (1) a proper number of experiments under comparable conditions and, therefore, proper statistical processing, with this being highly important for ‘noisy’ low-dose exposures; (2) non-genetic, i.e. biochemical and physicochemical mechanisms of cellular response, in accordance to “exposome” concept. Bioassays based on luminous marine bacteria, their enzymes, and fluorescence coelenteramide-containing proteins were used to compare results of low-intensity exposures at cellular, biochemical and physicochemical levels, respectively. Results of the cellular exposures were discussed in terms of hormesis concept. Bioluminescence time dependence under low-dose radiation exposures corresponded to hormesis or threshold models; no bioluminescence monotonic dependency on intensity of exposure (dose rate, radioactivity, concentration) was found. Bioluminescence activation and absence of its dependency on intensity of exposure can be accepted as features of cellular adaptive response. Changes of biological luminescence were analyzed and discussed for bioassays of lower organization level – enzymes and florescent protein.
An Experienced Surgeon Can Meet or Exceed Robotic Accuracy in Manual Unicompartmental Knee Arthroplasty
Authors: Bush Ashleigh N. , Ziemba-Davis Mary , Deckard Evan R. , Meneghini R. Michael
Published: August 2019

Background:

Reports in the literature indicate that implant placement is more accurate with robotic-assisted unicompartmental knee arthroplasty (UKA); however, these studies have not always accounted for surgeon experience. The purpose of the present study was to compare the accuracy of tibial component alignment in UKA between an experienced high-volume surgeon and the published data on robotic-assisted surgery.

Methods:

The radiographs made before and after 128 consecutive medial UKAs performed manually by a single surgeon using a cemented fixed-bearing implant were reviewed. Native tibial and tibial implant slope and varus alignment of the tibial implant were measured on preoperative and postoperative lateral and anteroposterior radiographs, respectively. The percentages of knees in which the postoperative measurements were within preoperative targets and the root mean square (RMS) error rates between the planned and achieved targets were compared with published robotic-assisted-UKA data.

Results:

In the present study, the proportion of manual UKAs in which the tibial component alignment was within the preoperative target was 66% (85 of 128), which exceeded published values in a study comparing robotic (58%) with manual (41%) UKA. The RMS error for tibial component alignment in the present study (1.48°) was less than published RMS error rates for robotic UKAs (range, 1.8° to 5°). Fifty-eight percent (74) of the 128 study UKAs were within the surgeon’s preoperative goal for tibial slope, which was closer to the published value of 80% for robotic UKAs than is the published rate of 22% for manual UKAs. The RMS error for tibial slope in the study UKAs (1.50°) was smaller than the published RMS error rates for tibial slope in robotic UKAs (range, 1.6° to 1.9°).

Conclusions:

Accurate implant alignment is important in UKA. In this study, an experienced surgeon achieved or exceeded robotic accuracy of tibial implant alignment in UKA. However, the relationship between implant position and patient outcomes is unknown, and a consensus on ideal surgical targets for optimal implant survivorship has yet to be established.

Published: August 2019

Background:

Newer designs and techniques of total ankle arthroplasty (TAA) have challenged the assumption of ankle arthrodesis (AA) as the primary treatment for end-stage ankle arthritis. The objective of this study was to compare physical and mental function, ankle-specific function, pain intensity, and rates of revision surgery and minor complications between these 2 procedures and to explore heterogeneous treatment effects due to age, body mass index (BMI), patient sex, comorbidities, and employment on patients treated by 1 of these 2 methods.

Methods:

This was a multisite prospective cohort study comparing outcomes of surgical treatment of ankle arthritis. Subjects who presented after nonoperative management had failed received either TAA or AA using standard-of-treatment care and rehabilitation. Outcomes included the Foot and Ankle Ability Measure (FAAM), Short Form-36 (SF-36) Physical and Mental Component Summary (PCS and MCS) scores, pain, ankle-related adverse events, and treatment success.

Results:

Five hundred and seventeen participants underwent surgery and completed a baseline assessment. At 24 months, the mean improvement in FAAM activities of daily living (ADL) and SF-36 PCS scores was significantly greater in the TAA group than in the AA group, with a difference between groups of 9 points (95% confidence interval [CI] = 3, 15) and 4 points (95% CI = 1, 7), respectively. The crude incidence risks of revision surgery and complications were greater in the AA group; however, these differences were no longer significant after adjusting for age, sex, BMI, and Functional Comorbidity Index (FCI). The treatment success rate was greater after TAA than after AA for those with an FCI of 4 (80% versus 62%) and not fully employed (81% versus 58%) but similar for those with an FCI score of 2 (81% versus 77%) and full-time employment (79% versus 78%).

Conclusions:

At 2-year follow-up, both AA and TAA were effective. Improvement in several patient-reported outcomes was greater after TAA than after AA, without a significant difference in the rates of revision surgery and complications.

Background:

Non-insertional Achilles tendinopathy is a common disorder that may be treated with surgical debridement. A flexor hallucis longus (FHL) transfer is recommended if debridement of ≥50% is performed; however, there are no biomechanical data to support this. The purpose of this study was to assess the added biomechanical strength provided by an FHL transfer with incrementally sized non-insertional Achilles tendon defects.

Methods:

Thirty matched-pair below-the-knee cadaveric specimens (n = 60) (mean age at the time of donor death, 67 years; range, 36 to 74 years) were obtained and randomly divided into 3 groups according to whether the defect was 25%, 50%, or 75% of the tendon width. One specimen of each pair was then randomly selected to undergo FHL transfer using interference screw fixation. All specimens then underwent cyclic loading of 100 N, and elongation of the medial and lateral limbs of the tendon defect was recorded. The constructs were then loaded to failure to measure stiffness, ultimate strength, and peak elongation before failure.

Results:

The specimens with a 75% defect had significantly less elongation of the medial and lateral tendon-defect limbs when an FHL transfer had been done (p < 0.05). Ultimate load to failure was significantly increased in all groups (by 242 to 270 N depending on the defect size) following FHL transfer. Failures usually occurred through the tendon defect in the 75% and 50% defect groups, whereas all failures occurred at the Achilles tendon insertion when a 25% defect had been created. No significant differences were found in peak elongation with the addition of an FHL transfer. FHL augmentation resulted in significantly greater stiffness in the 25% and 75% defect groups (p < 0.05).

Conclusions:

This study showed that an FHL transfer significantly increased load to failure of Achilles tendons with a non-insertional defect involving 25%, 50%, and 75% of the tendon width. The mechanism of failure was usually through the defect in the specimens with a 50% or 75% defect, supporting the use of FHL augmentation with debridement of ≥50%.

Clinical Relevance:

The present study supports the mechanical concept that FHL transfer is indicated when debridement of the Achilles tendon is ≥50%.

Hilsa Tenualosa ilisha  (Hamilton, 1822), one of the important commercial fish species in South Asian countries has received much attention for its conservation through captive breeding and seed production. The present study attempted to breed the fish by dry stripping in river Hooghly. Eggs were incubated at 22.8 and 28.30C temperatures in estuarine, pond and tap water. The hatching rate recorded was higher (p<0.05) in pond water (88-96%) compared to estuarine (70-76%) and tap water (72-74%) at both  temperatures tested. Incubation period (19-22 h) and hatching rates in the three water media were not influenced by tested temperatures. Hourly changes in embryonic development till hatching and daily changes in 0-10 day old larvae are described in this paper.

Stock identification of fish plays a significant role in management of fishery resources. It is considered as the precursor to species conservation and imperative for declining fish populations. The stock structure of Clupisoma garua (Hamilton, 1822) populations of Ganga riverine system was studied using truss network analysis. A total of 306 fish specimens obtained from river Ganga in Allahabad, Farakka and Triveni were used to construct the truss network. The truss variables were subjected to principal component analysis (PCA) in which the first component explained 46.71% and the second 14.66% representing body depth and caudal regions of fish, respectively. Bivariate plots of PCA and discriminant function (DF) analysis revealed that it is a single continuous stock in the study area of the river Ganga and the misclassification of DF indicated only a marginal morphological difference. The results indicated the need for a uniform management strategy appropriate for population of C. garua in the river Ganga.

The swimming crab, Charybdis (Goniohellenus) longicollis Leene, 1938, is a Lessepsian migrant into the Mediterranean and little is known about its biology in Iskenderun Bay, north-eastern Mediterranean, Turkey. The size of crabs, sex-ratio and spawning period of this species was defined from 951 specimens in order to understand their reproduction and development in the NE Mediterranean Sea. The crabs were found to occur throughout the year. Carapace width (CW) ranged between 7.22 to 100.60 mm and total weight ranged from 1.34 to 164.09 g. Male-female sex ratio was 0.6:1. Highest gonado-somatic index (GSI) was seen in March and September for females and in May for males. Ovigerous females were present throughout the year, with peak spawning activity in July and September. The CW of the ovigerous female crabs ranged between 23.71 and 95.93 mm. In winter months, GSI of males and females decreased. However, spawning season of C. (G.) longicolis in Yumurtalık Cove was observed throughout the year.
Environmentally Friendly Subsea Pipeline Decommissioning
Authors: Fielder Daniel , McGarry Rory
Published: August 2019

Objectives/Scope

Subsea pipeline decommissioning for either abandonment or retrieval is hazardous for both divers and the marine environment. This presentation reports on the development of a Fast Intervention Tool (FIT) for pipeline decommissioning by Webtool with input from Chevron Energy Technology Company. The FIT reduces the risks to divers and enables a quicker operation while avoiding the need for a containment dome during pipeline cutting and retrieval.

Methods, Procedures, Process

Sophisticated measures are taken to reduce the hazards to divers and the impact on the marine environment during pipeline decommissioning. Yet, traditional cutting technologies can undermine these best intentions. Diamond wire or other types of saw are time consuming and prone to jamming as the pipe moves during the cut. The containment dome used to catch contaminants that leach out during cutting and retrieval cannot "follow" the pipe as it is retrieved via a crane, therefore additional measures are needed to plug or seal to the pipe end before retrieval. The Fast Intervention Tool presented here addresses these shortcomings.

Results, Observations, Conclusions

The FIT combines lifting, crimping, injection and cutting in a single deployment frame which also contains the hydraulic control system. Deployed using a barge crane, the FIT assembly is lowered over a pipeline on the seabed, with either a diver or ROV to position it. The FIT cycle time to lift, crimp, inject sealant and cut is under 1 hour (excluding vessel or set up time) after which the pipe can now be safely recovered topside without leakage. The spike injector and blades will perform a number of cycles, therefore running costs are low; the only major consumable cost is the sealant itself. Webtool has completed FIT conceptual design and in-house development and testing and is now preparing a working prototype for hyperbaric and sea trials.

Published: August 2019

With the further exploration of oil and gas, we have to search for new resources which buried in deep strata, and most of the deep and ultra-deep wells are categorized in high-pressure/high-temperature (HPHT) wells. The problem of high temperature and the challenge to the existing downhole equipments are becoming increasingly prominent, where the drilling depth is severely restricted. The conventional measurement while drilling tools with common electronics will experience very high failure rates at these conditions.

One of the solutions is called the active cooling technology, which can transfer the heat from electronics system to downhole environment. By this way, the temperature control of downhole instrument circuit system is realized.

The active cooling technology is expounded in this paper, expecially about the principles and development status of each system. After evaluating and analyzing the characteristics of this technology, the function of heat transfer and constituent elements for the cooling system are summarized.

The study from this work demonstrates the future work for downhole cooling technology: large refrigeration capacity, small size, strong adaptability and modularization.
