Evolution of the Tension Leg Platform
Authors: Carpenter Chris 
Published: September 2020

This article, written by JPT Technology Editor Chris Carpenter, contains highlights of paper OTC 30752, “The Tension Leg Platform: From Hutton to Big Foot,” by Steven J. Leverette, Leverette Offshore, and Stephen B. Hodges, Shell (Retired), prepared for the 2020 Offshore Technology Conference, originally scheduled to be held in Houston, 4-7 May. The paper has not been peer reviewed. Copyright 2020 Offshore Technology Conference. Reproduced by permission.
The complete paper is a comprehensive discussion of the development and deployment of the tension leg platform (TLP), one of the four major platform types that also include floating production, storage, and offloading (FPSO) vessels; semisubmersible floating production systems; and spar platforms. The authors summarize the evolution of the TLP during a nearly 4-decade span and provide a retrospective of the progression of TLP technology, including hull shapes, tendon connectors, flex elements, and riser systems.
A Design Driven by Function
Although the technology involved may be impressive, the authors remind that essentially it is merely a means of supporting a payload economically in deep water within required motion limits. The ultimate objective is to provide the most cost-effective, safe, reliable platform to meet functional requirements.
After almost 50 years of deep water development, platform concepts have broadly stabilized into four categories of functionality: semisubmersibles, TLPs, spars, and ship-shaped FPSOs. Each of these concepts brings unique functionality with different cost/benefit tradeoffs.
The driver behind the TLP concept was straightforward from an operator’s perspective: Provide a platform that behaves like a fixed platform with regard to the wells (i.e., dry trees; direct vertical access to wells; minimal tensioner stroke, allowing an array of wells in close proximity without giant tensioner systems such as those found on drilling semisubmersibles; and enabling export risers) in water depths much deeper than any fixed platform.
This functionality, however, comes at a cost. While a semisubmersible may look similar in terms of hull and topsides, a TLP designed for the same payload requires 10 to 30% more displacement to provide the pretension in the tendons that keeps them in tension even in the most severe environmental conditions. The TLP also features 10 to 30% more freeboard to account for set-down at large offsets. While a semisubmersible, spar, or FPSO rides the tide and waves, a TLP acts like a fixed structure and, furthermore, is pulled down in the water geometrically at offset positions. The cost of this phenomenon must be offset by improved functionality. Thus, a large TLP with a full drilling rig and 24 wells can be an excellent choice for a large, centralized reservoir that can be drilled from a single location, but it makes little sense in developing a group of small reservoirs spread out over a region.

Abstract
Background Up to 50% of medicines are not used as intended, resulting in poor health and economic outcomes. Medicines optimisation is ‘a person-centred approach to safe and effective medicines use, to ensure people obtain the best possible outcomes from their medicines’. The purpose of this exercise was to co-produce a prioritised research agenda for medicines optimisation using a multi-stakeholder (patient, researcher, public and health professionals) approach. Methods A three-stage, multiple method process was used including: generation of preliminary research questions (Stage 1) using a modified Nominal Group Technique; electronic consultation and ranking with a wider multi-stakeholder group (Stage 2); a face-to-face, one-day consensus meeting involving representatives from all stakeholder groups (Stage 3). Results In total, 92 research questions were identified during Stages 1 and 2 and ranked in order of priority during stage 3. Questions were categorised into four areas: ‘Patient Concerns’ [e.g. is there a shared decision (with patients) about using each medicine?], ‘Polypharmacy’ [e.g. how to design health services to cope with the challenge of multiple medicines use?], ‘Non-Medical Prescribing’ [e.g. how can the contribution of non-medical prescribers be optimised in primary care?], and ‘Deprescribing’ [e.g. what support is needed by prescribers to deprescribe?]. A significant number of the 92 questions were generated by Patient and Public Involvement representatives, which demonstrates the importance of including this stakeholder group when identifying research priorities. Conclusions A wide range of research questions was generated reflecting concerns which affect patients, practitioners, the health service, as well the ethical and philosophical aspects of the prescribing and deprescribing of medicines. These questions should be used to set future research agendas and funding commissions.

Abstract
Background Rare disease patients and carers report significant impacts on mental health but this has not been extensively studied. We explored the experiences of UK-based individuals through an online survey, and offer recommendations for policy and practice developed with a multi-stakeholder workshop. Results In total 1,355 patients and 571 carers responded to the survey.Due to their rare condition, the majority of respondents had felt worried/anxious (95%); stressed (93%); low/depressed (90%); emotionally exhausted (88%). Thirty-six percent of patients and 19% of carers had had suicidal thoughts.Challenges that are particular to rare conditions and which negatively affect mental health included limited knowledge of the condition amongst healthcare professionals (88%), not being believed or taken seriously by healthcare professionals (80%), and lack of available information about the condition (76%). Only 23% of respondents felt healthcare professionals considered mental health as equally important as physical health. Almost half of patients (46%) and carers (48%) reported never having been asked about their mental health, or that of the person they care for, by healthcare professionals.Forty-six percent of respondents had received professional psychological support; the most common reason for not having accessed professional psychological support was that it had not been suggested (41%).Fifty-nine percent of respondents had accessed sources of additional emotional support, such as patient groups, with the majority (75%) having found this support themselves. With input from our multi-stakeholder workshop we developed recommendations for healthcare professionals to be supported to effectively and sensitively recognise and address patients’ and carers’ mental health needs; and for service level coordination of care to integrate professional psychological support with rare disease services.Conclusions Living with a rare disease substantially impacts mental health. Many of the drivers of poor mental health reflect issues specific to managing rare conditions. To meet existing UK government commitments, there should be a focus on empowering healthcare professionals who treat rare disease patients and on integration of mental health support with rare disease services.

Abstract
Background: Selenium is an essential trace element, and selenocysteine (Sec, U) is its predominant form in vivo. Proteins that contain Sec are selenoproteins, whose special structural features include not only the TGA codon encoding Sec but also the SECIS element in mRNA and the conservation of the Sec-flanking region. These unique features have led to the development of a series of bioinformatics methods to predict and research selenoprotein genes. There have been some studies and reports on the evolution and distribution of selenoprotein genes in prokaryotes and multicellular eukaryotes, but the systematic analysis of single-cell eukaryotes, especially algae, has been very limited. Results: In this study, we predicted selenoprotein genes in 137 species of algae by using a program we previously developed. More than 1000 selenoprotein genes were obtained. A database website was built to record these algae selenoprotein genes (www.selenoprotein.com). These genes belong to 42 selenoprotein families, including three novel selenoprotein gene families. Conclusions: This study reveals the primordial state of the eukaryotic selenoproteome . It is an important clue to explore the significance of selenium for primordial eukaryotes and to determine the complete evolutionary spectrum of selenoproteins in all life forms.

Abstract
Background: Common Pekin and Muscovy ducks and their intergeneric hinny and mule hybrids have different abilities for fatty liver production. RNA-Seq analyses from the liver of these different genetic types fed ad libitum or overfed would help to identify genes with different response to overfeeding between them. However RNA-seq analyses from different species and comparison is challenging. The goal of this study was develop a relevant strategy for transcriptome analysis and comparison between different species.Results: Transcriptomes were first assembled with a reference-based approach. Important mapping biases were observed when heterologous mapping were conducted on common duck reference genome, suggesting that this reference-based strategy was not suited to compare the four different genetic types. De novo transcriptome assemblies were then performed using Trinity and Oases. Assemblies of transcriptomes were not relevant when more than a single genetic type was considered. Finally, single genetic type transcriptomes were assembled with DRAP in a mega-transcriptome. No bias was observed when reads from the different genetic types were mapped on this mega-transcriptome and differences in gene expression between the four genetic types could be identified.Conclusions: Analyses using both reference-based and de novo transcriptome assemblies point out a good performance of the de novo approach for the analysis of gene expression in different species. It also allowed the identification of differences in responses to overfeeding between Pekin and Muscovy ducks and hinny and mule hybrids.

Abstract
Background: An increasing number of gastrointestinal cancer (GI) patients suffer from the side effects of cancer treatment that can affect their psychosocial health outcomes such as mood states and quality of life. Despite its demonstrated usefulness in female cancer patients, the Supportive Expressive Group Therapy (SEGT) has not been tested in male cancer patients. The current study sought to examine the longitudinal effects of a professionally-led, men-only supportive-expressive group therapy (SEGT) on mood states, coping, and quality of life (QoL) in male GI cancer patients. Methods: Male GI cancer patients (n=31), at different stages of cancer treatment, were recruited from an ongoing men-only biweekly GI cancer support group. Data were collected at baseline (before or near the beginning of group attendance) and at three months and six months follow-up. All outcomes were patient-reported and included demographic data as well as the validated questionnaires: Profile of Mood States (POMS) for mood states, Functional Assessment of Cancer Therapy-General (FACT-G) for QoL, and Ways of Coping-cancer version (WOC) for coping. Linear mixed models were used to examine the change in the outcomes over time. Effect sizes were estimated using Cohen’s d. Results: The Anxiety (p=.04; d=0.70), Depression (p=.03; d=0.93) and Anger (p=.04; d=1.28) subscales of the POMS decreased between baseline and six months. Participants also reported improvements in coping through Distancing (distancing oneself from negative thoughts, being more accepting of the situation, and looking for positives) of the WOC (p=.04; d=0.4) between baseline and six months. There was no change in any of the FACT subscales (QoL) over time. Conclusions: This is the first study to investigate the effects of a SEGT intervention in male cancer patients. SEGT resulted in improved mood states and coping in male GI cancer patients; however, there was no change in measures of QoL. Given the direct effects of SEGT on anxiety, depression and anger, as well as a strong association between anger and depression in men as reported in past studies, SEGT could be impactful in improving psychosocial health outcomes in male GI cancer patients.

Abstract
Background As the first domestically produced Chinese surgical robot for clinical use, the Micro Hand S robot has been applied to total mesorectal excision (TME) for rectal cancer in our center since 2017. The aim of this study was to evaluate the safety and feasibility of the Micro Hand S robot-assisted TME (R-TME) in comparison with laparoscopic TME (L-TME).Methods Between May 2017 and February 2018, patients who underwent R-TME and L-TME in the Third Xiangya Hospital were included in this study. The data including intraoperative outcomes, postoperative outcomes, pathological outcomes, and functional outcomes were analyzed and compared. Results Totally, 30 patients underwent L-TME and 21 patients underwent R-TME. The patient characteristics of the two groups were similar. Regarding intraoperative and postoperative outcomes, the R-TME group had significantly less blood loss (95.2 vs. 130.0 ml, p = 0.022), shorter time to first flatus (2.1 vs. 2.9 d, p = 0.017) and first liquid intake (2.8 vs. 3.7 d, p = 0.027) than the L-TME group. There was no significant difference in the operative time, conversion, protective ileostomy, length of hospital stay, pain score, complications, and 30-day mortality between the two groups (p > 0.05). In addition, the pathological and functional outcomes also did not differ significantly.Conclusion The Micro Hand S robot-assisted total mesorectal excision is safe and feasible with short-term outcomes comparable to laparoscopic surgery. Prospective and large sample size trials are needed to further confirm this conclusion.

Abstract
Background: The COVID-19 outbreak has been declared a public health emergency of international concern. As the virus is transmitted through close contact and droplets, frontline HCWs caring for COVID-19 patients are at risk of the infection. This study aimed at assessing knowledge and preventive practices towards Covid-19 among health care providers in selected health facilities of Illu Aba Bor and Buno Bedele zones, Southwest Ethiopia. Methods: An institution-based cross-sectional study was conducted from April to May 2020 among 330 health workers in selected health facilities of Illu Aba Bor and Buno-Bedelle Zones, Southwest Ethiopia. Data were collected using a self-administered structured questionnaire. The collected data were entered onto Epidata version 3.1 and exported to SPSS version 23 for analysis. Bivariate and multivariable logistic regression analysis was used to identify independent predictors of preventive practices towards Covid-19. Statistical significance was declared at a p-value of < 0.05. Result: Greater part (93.3%) of the respondent demonstrated good knowledge towards COVID-19 and the mean (±SD) knowledge score was 9.0 4± 1.06. Nearly two-thirds (64.2%) of the study participants had good infection prevention practices. Being male (AOR=3.65, 95% CI: (1.96, 6.80)), education level (AOR=1.82, 95% CI (1.02, 3.22)), profession (AOR=3.17, 95% CI (1.08, 9.33)), service year ( 5 – 10 years) (AOR=2.00 (1.02, 3.92)) and more than 10 years (AOR=3.14 (1.51, 6.52)) , availability of personal protective equipment (AOR=1.96 (1.06, 3.61)) and Knowledge level (AOR=2.61 (1.48, 4.62)) were independent predictors of COVID-19 preventive practices. Conclusion: The overall level of knowledge of HCWs was good. However, the practice was relatively low. Gender, educational status, profession, year of service, knowledge towards COVID-19, and availability of personal protective equipment were independent predictors of good infection prevention practices. Optimizing the infection prevention and control loop of the health facilities is recommended.

Published: September 2020

Abstract
Background: Ehrlichia is a genus of Rickettsiales bacteria closely related to human/animal disease and it plays an important role in public health. Naturally they are hosted by mammals such as canines, bovines, wild rodents and vectored by ticks. Results: In this study, we collected 121 rodent samples including 67 Niviventer fulvescens, 27 Rattus tanezumi, 24 Chiromyscus sp., 2 Rattus nitidus and 1 Leopoldamys edwardsi from Hainan province, which consists of the second largest island in China. The presence and genetic diversity of Ehrlichia was evaluated and characterized by amplifying and sequencing the 16S rRNA, groEL and gltA genes. An Ehrlichia species was detected in 5 of the 67 Niviventer fulvescens samples (7.46%). The 16S rRNA, groEL and gltA genes show highest 99.20%, 89.87% and 83.86% identity to known Ehrlichia sequences. In the phylogenetic trees they form a distinct cluster from any other species. ﻿Conclusions: We propose that this species present a putative novel Ehrlichia species nominated as ‘Candidatus Ehrlichia hainanensis’. Its pathogenicity to human is still to be further researched and molecular surveillance in local populations is needed.

Abstract
It is proved that the effect of tannin concentration on the mycelial growth of fungi. Auricularia cornea (white strain) were treated with different concentrations of tannins in petri-dishes and liquid shaking flasks. The growth rate of mycelium, the ratio of clamp connection, morphology of mycelium, biomass of mycelium and activity of antioxidant enzymes were determined. The results showed that different concentrations of tannin significantly decreased the rate of mycelium. However hign concentration of tannin stress increased the content of thiobarbituric acid in mycelia and had obvious time and concentration effects. Different antioxidant enzyme activities also had different responses to tannin stress. It provides theoretical basis for fungi to utilize and develop substrates containing tannin such as pine.

Abstract
Background:Ischemic Heart Disease(IHD) characterized by atheroma formation, is a leading contributor for the rising disease burden of chronic non-communicable diseases in Sri Lanka. Even though excessive salt-consumption has been attributed with hypertension, documented literature is scarce on exploring its direct association with atheroma formation with primary data. Coronary-Artery- Bypass-Grafting(CABG) is done as a tertiary preventive measure for IHDs. The aim was to estimate the sodium-intake and to describe the association of salt consumption and atheroma formation among preoperative patients undergoing CABG at Sri Jayewardenepura General Hospital, Sri Lanka.MethodsA descriptive cross-sectional study was done on a calculated sample size of 213 participants who were awaiting CABG at SJGH. An interviewer-administered Additional file 1 was used, and dietary intake of sodium was calculated with food-frequency tables and web-based tools. A data extraction form was used and details regarding Coronary arterial segments with atheroma formation were obtained from angiogram reports. After exploring the normality, Spearman-correlation-coefficient and Mann-Whitney-U tests were used to explore associations of atheroma formation. Independent association of sodium-intake and Coronary arterial segments affected with atheroma was explored with multiple-logistic regression. ResultsThe sample was with a male preponderance(male to female ratio=3:1). Comorbidities were observed in a notable proportion: diabetes(47%), dyslipidemia(40%), hypertension(56%). The median(IQR) of BMI and waist circumference were 25.00(23.00-27.00)kg/m2 and 87.00(82.00-91.00)cm. The median(IQR) sodium-intake was 5875.50(4905.25-7091.25)mg. All participants (n=210) had a sodium intake of more than 2000mg/day. Sodium intake(rs=0.599,p<0.001) and BMI(rs=0.634,p=0.034) were significantly associated with atheroma segments whereas age, gender, diabetes, hypertension, dyslipidemia, waist circumference was not(p>0.05). Sodium intake was found to be an independent predictor of affecting “5 or more segments” when multiple logistic regression was applied(OR= 2.25,CI=1.41 to 3.61).Conclusions and RecommendationsThe daily intake of sodium by a regular person is more than the dietary recommendations in the study sample. Salt intake reflected by sodium intake seemingly increase the risk of atheroma formation in more coronary segments irrespective of age, sex as well as several known disease conditions and risk factors. More research must be promoted with analytical approaches in proving this hypothesis.
