The Indonesian plurality needs to be preserved and maintained in order to continue the unity of Indonesia. One of the Islamic teachings that taught plurality is the understanding of islam wasatiyah. This understanding needs to be taught to the generations of nations so that the generations of nations become the generations that can be spread out of Islamic teachings. One of the most important things to teach islam wasatiyah is a kiyai langgar. The presence of kiai langgar (priest) in the middle of the rural community is very necessary because the kiai become an example and role model for the societies. Kiai langgar becomes a magnet for society because his word becomes an argument for the element of society. Even, from long time ago up to this time, kiai langgar is being an educational subject, a local wisdom consevionest, and an Indonesian consevionest unity values. Although His existence has not recognized by everyone, but he has been consistently continued contributing to the Indonesian people. And also his existence became an oasis in the lives of the Indonesian people. The presence of a kiai Langgar becomes a blessing for the villager. the presence of kiai langgar becomes a solver of society's problems in daily life. He becomes a place where people can complain of grief and all the problems of conditionality, and become an avenger if there is a dispute between society and others. This main role becomes kiai langgar is an important man to teach Islamic religion from the village. This research studies the role of kiai langgar in treating Islamic wasatiyah teachings on Madura Island. This study uses qualitative methods with discrete analysis approaches.

Abstract
Upcoming ground- and space-based experiments may have sufficient accuracy to place significant constraints upon high-redshift star formation, Reionization, and dark matter (DM) using the global 21 cm signal of the intergalactic medium. In the early universe, when the relative abundance of low-mass DM halos was important, measuring the global signal would place constraints on the damping of structure formation caused by DM having a higher relic velocity (warm dark matter, or WDM) than in cold dark matter. Such damping, however, can be mimicked by altering the star formation efficiency (SFE) and can be difficult to detect because of the presence of Population III stars with unknown properties. We study these various cases and their degeneracies with the WDM mass parameter m
X using a Fisher matrix analysis. We study the m
X = 7 keV case and a star formation model that parameterizes the SFE as a strong function of halo mass and include several variations of this model along with three different input noise levels for the likelihood; we also use a minimum halo virial temperature for collapse near the molecular cooling threshold. We find that when the likelihood includes only Population II stars, m
X is constrained to an uncertainty of ∼0.4 keV for all models and noise levels at the 68% confidence level. When the likelihood includes weak Population III stars, m
X ∼ 0.3 keV, and if Population III star formation is relatively efficient, m
X ∼ 0.1 keV uncertainty, with tight Population III star formation parameter constraints. Our results show that the global 21 cm signal is a promising test-bed for WDM models, even in the presence of strong degeneracies with astrophysical parameters.

Abstract
Population studies of exoplanets are key to unlocking their statistical properties. So far, the inferred properties have been mostly limited to planetary, orbital, and stellar parameters extracted from, e.g., Kepler, radial velocity, and Gaia data. More recently an increasing number of exoplanet atmospheres have been observed in detail from space and the ground. Generally, however, these atmospheric studies have focused on individual planets, with the exception of a couple of works that have detected the presence of water vapor and clouds in populations of gaseous planets via transmission spectroscopy. Here, using a suite of retrieval tools, we analyze spectroscopic and photometric data of 25 hot Jupiters, obtained with the Hubble and Spitzer Space Telescopes via the eclipse technique. By applying the tools uniformly across the entire set of 25 planets, we extract robust trends in the thermal structure and chemical properties of hot Jupiters not obtained in past studies. With the recent launch of the James Webb Space Telescope and the upcoming missions Twinkle and Ariel, population-based studies of exoplanet atmospheres, such as the one presented here, will be a key approach to understanding planet characteristics, formation, and evolution in our galaxy.
Repurpose Offshore Pipeline as Energy Storage ROPES: Opening a New Market Segment Offshore

Abstract
There is a significant drive to decarbonise the energy system resulting in a need to integrate large quantities of intermittent renewable power into both onshore consumer grids and offshore isolated grids. This brings significant technical challenges that can be addressed using the right energy storage technology for future times of intermittency and peak power demands. The innovative Repurposed Offshore Pipelines as Energy Storage (ROPES) solution repurposes existing, aged offshore installations into energy storage systems based on proven hydro-pneumatic principles, towards a cost-competitive, highly reliable system. Findings from a recent Concept Assess study prove the cost competitiveness of the solution, thanks to alow Levelised Cost of Storage (LCOS), paired with the value of deferring full decommissioning of existing assets. The study scope covers aspects of market recognition, technical feasibility, risk and opportunity assessment, cost estimates and value delivery to potential clients. Four case studies covering potential prospects offshore Australia and in the North Sea illustrate the diverse architectural application of the solution. The resultant cost estimates form the NPV analysis, and eventually derive the solution LCOS, which shows cost superiority over marinised Li-ion batteries and is comparable to onshore battery systems. The solution shows clear benefits over a typical battery storage system, including reduced safety risks, less topside constraints along with a longer and predictable operating lifetime. The ROPES solution enables the storage of renewable power whilst allowing to optimise time and expenditure for decommissioning of existing infrastructure, therefore represents a unique opportunity to unlock a new market segment within the offshore energy sector.

AbstractThe move to reduce greenhouse gas emissions in the offshore hydrocarbons production industry has resulted in a growing interest in the possibility of using offshore wind to reduce on-platform power generation. While some offshore areas are progressing towards or planning for the use of offshore wind to electrify hydrocarbon producing platforms, they do not have the challenges associated with Newfoundland & Labrador's offshore environment.This region is prone to incursions by icebergs and pack ice, which would present a risk to offshore wind turbines. Analysis approachesto assess these risks, along with preliminary results, are presented herefor floating offshore wind turbines (FOWT).An area of interest (AOI), covering 45°N to 51°N and 45°W to 51°W, was defined covering all development licenses on the Grand Banks, Flemish Pass and Orphan Basin. Iceberg and pack ice contact rates and loads were calculated using data from the Nalcor NESS Metocean database, Canadian Ice Service (CIS) ice charts and satellite imagery. Ice loads corresponding to 50-year return periods levels were assessed, with and without ice management, giving a basis for determining whether ice management and/or disconnection capabilities are required. The frequency and severity of atmospheric icing of turbines was also modelled using available data and models.

Abstract
TAQA`s Otter field in the U.K. sector of the North Sea has been operating since 2002 with in-well electrical submersible pumps (ESPs) to boost production. It is predicted that the field will need some means of artificial lift to kick off oil production as the reservoir pressure decreases. A subsea multiphase boosting system was integrated into the existing facilities to provide a new, reliable, and highly energy-efficient pressure boosting solution for the Otter field. With gas cap from the wells, the main challenge for the multiphase pump (MPP) system was to generate sufficient differential pressure with only gas entering the pump station inlet. A second challenge was to avoid overheating the system with only gas flowing from wells.
A novel liquid extractor was developed, built, and tested in Bergen, Norway. Internal chambers in the liquid extractor separate gas and liquid fractions of the fluid. The liquid extractor is included in the pump station, together with a flow mixer, MPP, recirculation choke, and valves. The design of the liquid extractor ensures that liquid can be recirculated by the choke back to the pump inlet. The mixture of gas from wells and recirculated liquid allows the pump to generate sufficient differential pressure.
Testing of the entire pump station prior to subsea installation confirmed that the liquid was maintained in the station and the overall heat loss from the station was sufficient to prevent overheating during fluid recirculation. Hence, the new liquid extractor ensures sufficient time to allow for startup of a nonproducing field, which has also been supported by field experience. The pump station, including the new liquid extractor, was installed subsea in the Otter field in October 2018. The Otter field, with the MPP and the liquid extractor, has been in operation for 1,057 days at the time of writing with 100 % reliability and will significantly increase the total recovery of the Otter field compared to natural production.
Subsea Systems Life Extension of Bijupirá and Salema Fields

Published: April 2022

Abstract
This paper explains the efforts to assess the integrity status and to extend the life of the subsea system connected to a Floating Production Storage and Offloading vessel (FPSO) moored offshore in Brazil, at 700m water depth, set up in 2003 as the first IOC operated assets in Brazil.
The work performed covered the assessment of flexible risers, flowlines, umbilicals and rigid gas export line, comprising studies on operational history, simulations, in-loco special inspections (AUT, EMAT and Direct and Indirect flexible riser tensile armour inspections) and actual FPSO and risers' movement monitoring. Subsea equipment as Christmas trees, manifolds and PLETs were not included, as design life was sufficient.
The results found that some equipment was in remarkable good shape, whilst others had compromised integrity. Assessments demonstrated that some METOCEAN and motion data for the FPSO, utilized during the design phase, were non-conservative when compared to the real case, which led to under design of risers' fatigue life. In-loco verification of some equipment integrity revealed damages, probably related to fatigue associated with corrosion.
Improvements on the existing system and new monitoring techniques applied to the field, to assure safe operations past its original design life, are also depicted.
The work performed was pioneering on life extension of a subsea system for a field operated by an IOC in Brazil and can contribute to other operators facing ageing assets in the country.

Abstract
Brazilian pre-salt production development brought up a series of technological challenges to Petrobras over the last two decades. Despite all the innovations that have made feasible to produce oil in ultra-deep water, the deployment schedule of these projects still showed opportunities for improvement, according to other companies’ benchmark. Given the economical attractiveness of reducing the production schedule of greenfield development and the current increase of Petrobras production output subject to the term restrictions of the Production Sharing Contract, a strategic program has been implemented with focus on reducing the elapsed time since oil discovery until the start of its commercial production, also called PROD1000. This program considers all activities of a production development project, searching for optimizing governance, design, construction stages and deployment of production system so that first oil is anticipated. In subsea system, the term reduction strategy was based on four main pillars: interfaces pretreatment (ex. subsea & FPSO), agile bidding process, subsea components standardization and prequalification of suppliers.
