Design, Test and Validation of a 100% H2 Gas Turbine to Enable Energy Transition
Authors: Gabriele S. , Sarti G. , Baldini M. , Gerbi F. 
Published: October 2023

Abstract
In the global effort to reduce GHG emissions hydrogen plays a crucial role being one of the major carbon-free energy carriers to drive the change towards net-zero emissions target.
Although the interest in hydrogen has risen significantly in the last few years, the use of hydrogen blends in gas turbines is a well-established practice. Starting from the experience gained in decades of operation, nowadays a new generation of gas turbines is being designed specifically to operate with pure hydrogen in all conditions, from start-up to base and partial loads. Despite the concept of feeding gas turbines with hydrogen is not new, the technology effort necessary to implement a low emission 100% hydrogen combustion system is massive, representing the state of the art of the development of innovative technologies for hydrogen utilization and becoming one of the main roads to achieve the GHG reduction goal.
For the development of a new 100% hydrogen combustor, predictive models are fundamental, providing accurate and reliable predictions to optimize the design of the equipment and to ensure the proper low-emission operation of the gas turbine. Due to the complexity of the involved physical laws, the reliability and robustness of the predictive models depends heavily on testing activities that allow to use real data to develop and calibrate the predictive models.
With this aim, a hierarchical approach to testing has been adopted: first the physical model, its calibration and its accuracy have been benchmarked against Full Annular Rig test and dedicated bench tests. Although simplified with respect to a full-scale gas turbine, those tests have the advantage of being more controlled, providing data and details not available on a full-size machine. Then the models have been tested and fine-tuned against a full-scale gas turbine test.
The whole process including design, test and validation of a combustion system capable of burning 100% hydrogen will be analyzed in depth in the paper.

Published: October 2023

Abstract
The objective of this paper is to present technical specifications of a logging tool where it can identify the well integrity system failure due to various scenarios including:
communication between Borehole and Tubing-Casing Annulus, or TCA (A-annulus) through one of the completion elements; leak of the tubing itself; communication between TCA and the 1st Casing-Casing Annulus, or CCA1 (B-Annulus); and communication between CCA1 and the 2nd Casing-Casing Annulus, or CCA2 (C-annulus), when the movement of unwanted fluid happened through the casing leaks.
There is a described approach when downhole data which includes high-definition spectral noise and high-precision temperature (HPT) logging results is supporting the surface pressure data, and the source of Sustained Annulus Pressure (SAP) in all annuli was revealed confidently.
The diagnostics can be conveyed in boreholes that are mainly filled by gas with some liquid hydrocarbon and water content. The survey also can be done under two types of conditions: shut-in, which is the baseline, and several dynamic conditions. The purpose was to change the well regime and capture events that are related to well integrity issues. This comprehensive survey results will lead to correct decisions of well workover.

Abstract
This paper discussed the operationalization effort of an automated and integrated Machine Learning (ML) system to support Production Enhancement (PE) opportunity generation and workflow processes driven by data analytics. The digital solution focuses on prescriptive engines to calculate variables such as potential gain, Locked-In-Potential (LIP) and behind casing potential using big data such as reservoir properties, historical production, well intervention history and petrophysics interpretation. Additionally, the solution provides constraint detection for each well using an Analytic Hierarchy Process (AHP) on conventional petroleum engineering workflows.
The objective of this paper is to demonstrate the operationalization effort that was utilized to gain the maximum value possible from the workflow by connecting people with this digital solution. The efforts are founded on the following three (3) key methodologies: 1) Operationalization, 2) Optimization, and 3) Value Creation.
This digital solution has enabled engineers to identify and rank PE opportunities more quickly and efficiently, leading to a potential increase in field production and recovery. Adopting this methodical approach which utilizes advanced data analytics and ML, automated and systematic PE opportunity has been made possible and this has given a positive impact on work process whereby engineers will have more time to focus on strategic and value-added activities, increasing workforce satisfaction and productivity. As of this report, this digital solution is currently available in over forty (40) different fields. The goal is to connect people with the enhanced workflow, which will make it possible for workforce upskilling and foster a better collaborative work environment to boost field productivity and work process efficiency.

Published: October 2023

Abstract
Linerless casing design is a cost-effective solution to reduce the well delivery time, however it presents challenges in achieving excellent cement quality across the interval. ADNOC Onshore Cementing team developed a cement slurry design to cover the deep 9-5/8" casing to surface with modified cement designs to enhance cement quality.
This paper presents drilling and cementing operation for an extended reach well (ERD) landing in a high inclination reservoir. A lightweight, expandable, and gas-tight slurry was designed with flexible high-density slurry to mitigate risk. Cementing best practices were followed during execution, including casing centralization, wiper plug displacement, and pressure testing. The displacement efficiency was improved by using a pump scrubbing spacer. The paper highlights the benefits of this technique and how it contributes to the success of the cementing operation. The paper also discusses the challenges and lessons learned during the operation, such as unexpected formation pressures and equipment malfunctions.
In conclusion, the slurry design and implementation of the cementing best practice as previously stated were studied in 3 wells and has successfully achieved to provide an excellent zonal isolation through the entire wellbore interval. The linerless cementing practice proved its success and efficiency in terms of well stability and cement quality as reflected in the simulations, lab test results, Cement Quality Parameters (CQP) and Cement Evaluation Tools (CET).
Due to the positive results, the new modified cement design is currently being used as a best practice for executing any future linerless cement jobs
Steam Trap Management Re(de)fined

Published: October 2023

Body steam trap management is one of the key programs in energy management. Considerable amount of steam as energy and water as condensate is lost through failed traps. In a well-maintained steam distribution system distribution loss of 5% is acceptable and losses increase drastically to 10 to 15 % in a poorly maintained system. Trap population is a mix of different types of traps such as thermodynamic or disc type, bimetallic, inverted bucket, float, and thermostatic. Though the professional fraternity as well as management agrees that significant contribution of losses is due to failure of thermodynamics traps where failure rates are as high as 40%, only few companies acted to adopt alternate trap types and reduce the failure rate. Very few have leveraged technology to detect failure as well as diagnose type of failure.
Millions of dollars need to be invested in online trap management systems and fear of uncertainty overwhelmed sound engineering judgement to adopt alternate traps over conventional thermodynamic traps. This prevented addressing the perennial issue of steam loss through traps. 10% loss has become the acceptable norm. This paper discusses current conditions at field based on survey, alternates to disc traps, failure rate reduction after replacing disc traps, strategy to manage traps, and overall net benefits.
Steam trap management program was revisited using extensive field survey data, analyzing types of traps based on application and steam pressure levels. Trap failure rate matrix was developed based on type and pressure levels. Condensate recovery was used to measure or determine the effectiveness of disc type trap replacement. A strategy was developed to maximize condensate recovery with optimized investment. This helped to prioritize areas where disc type traps are to be replaced with suitable alternate types and yield desired results. Actual failure rate comparison was made before and after disc type trap replacement. Condensate recovery improved from 85 to over 92%. It is expected to reach 97%, if all disc type traps are replaced. Failure rate of traps are expected to maintain around 3%.

Abstract
This paper presents an integrated asset modeling approach for reservoir coupling of 2 Sour offshore Abu Dhabi fields with three and four complex undeveloped reservoirs for each field respectively with different fluid types ranging from low CGR sour gas to sour oil in one shared surface network (Figure 1). The proposed methodology involves the development of a fully coupled surface and subsurface models to optimize field development with gas lift, water injection and gas recycling as part of the design and operations’ excellence.
In our quest to optimize field development strategies, we have developed a fully coupled surface and subsurface model. This approach integrates gas lift, water injection and gas recycling operations, paving the way for an enhanced understanding of their synergistic effects on reservoir performance. By concurrently accounting for these three crucial facets of oil field operations, the proposed model transcends conventional decoupled modeling frameworks.

Published: October 2023

Abstract
In the energy industry and its product transportation, Pipelines are considered as safe and economical and therefore, plays an important role and considered as one of the critical asset. More than 60% of pipelines (oil, gas, water & condensate) has been in operation for more than 35 years exceeding its normal design life. And there is a requirement for continued safe production from the field. Therefore, maintaining integrity of these pipelines are becoming critical and this can be achieved effectively by having an intensive integrity management system in place which helps in continuous inspection, assessment and mitigation to evaluate the risk exposure. This requires highly proven and innovative inspection and integrity assessment tools and techniques that helps in accurate and safe endorsement of fitness for service thereby, extending the operating life of the pipelines.
There are instances or scenarios where some of these operational pipelines with exceeded design life are highly corroded and requires significant number of intervention and repair and this becomes more challenging and un-economical being an offshore operations. Furthermore, in these scenario the subsea pipeline is recommended to be decommissioned within a prescribed timeline and replaced by a new pipeline and, this has created a window of vulnerability to failure during the transition from decommissioning "end of life" pipeline phase with the new pipeline replacement project. Due to this situation, we have explored an innovative solution together with specialized subsea composite contractors to develop and test high strength composite with resins that are hydrophobic and can be applied in the underwater condition. These subsea composite materials provide a "Double Skin" of composite wrapping on weak links/corroded sections in the subsea pipelines, ensuring safe operations for about 5-7 years until the pipeline is replaced.
This paper captures the lessons learnt and continuous improvements being made to further develop subsea composite repair technology for fast and low cost temporary subsea pipeline interventions. Case study of actual subsea pipelines repair with composites whose life has been extended and are still in operations will be presented in the section below. This deferment of capital cost in new pipelines enables the company to realize profitability while ensuring maximum availability and sustainable subsea infrastructure.
This paper address the risk exposure identified and effective mitigation deployed using innovation driven repair solutions and with this subsea strategy the ageing pipelines has achieved and maintained a "Zero Leak and Zero business interruption" track record.

Abstract
Over the last decades, anticipating on the global increase in energy demand, necessary developments on the seabed have taken place that interfered with ocean ecosystems and related biodiversity enhancement capacities. As the awareness of this problem nowadays grows - as well as the efforts of large scale ecosystem restoration - the need for a reliable solution targeting the core of the problem does so as well: insufficient availability of environmental information to support decision making systems. By introducing AI-driven ecosystem insights, the nature inclusive scope on projects can be broadened and decision making as well as environmental requirements within the marine industry can be brought to a higher level. In working towards biodiversity enhancement at scale, creating a Digital Twin of the project site can give direction for decision making. This interactive digital blueprint offers valuable insights into the physical assets and the potential of integrating state-of-the-art biodiversity solutions. Following from our experience, we know that the protection and restoration of seaweed, oyster and mussel reefs, seagrass, coral and mangroves can significantly increase the ecosystem services they deliver. The Digital Twin will relate ecosystem services with economic indicators and show amongst others; the potential biodiversity increase, CO2 sequestration, oxygen level increase and corresponding revenues. It can track the impact and continuously demonstrate progress and status by integrating 3rd party monitoring and data collection methods.Worldwide offshore energy systems develop more and more towards multi-use, which is key to enhancing seabed biodiversity. The opportunities for multi-use are endless, but the inclusion of ecosystem restoration can only be successful if the right data is collected and insights can be shown. If we can better understand the system in which the intervention is taking place, we can better make the right decisions.An intelligent tool to create high traction and impact on marine ecosystems at scale, as it facilitates energy companies and operators to evaluate targeted and high-value environmental solutions. It will break down the complex challenge of biodiversity, and allows for easy and impactful decision-making on this topic. This will release pressure on specific species, and nature in general, and will allow them to thrive again.Efforts to enhance ecosystem services, combined with AI-driven insights, unleash a new sea of opportunities for nature inclusive works. Currently under development in collaboration with universities and research institutes, our aim with this paper is to inspire and invite marine industry partners to join our upscaling efforts.

Published: October 2023

Abstract
Wind Power is an important source of renewable energy. It cannot be polluted; it is unlimited and reduces the use of conventional fossil fuels i.e., the origin of greenhouse gasses causing global warming. On other hand, the offshore industry is facing many challenges in the transportation of breakbulk cargo. The challenges include harsh environments, remote locations, limited infrastructure, and time and cost restrictions. Traditional methods of shipping often struggle to accomplish the specific requirements of offshore breakbulk logistics. This complete paper explores the installation of first Wind Farm Project in the UAE at offshore locations and logistics barges concept as an answer to address the challenges encountered at such locations i.e., offshore. Logistics barges are a cost-effective, flexible, and an efficient substitute for transporting breakbulk / project cargo to offshore locations. Through analyzing the benefits and considerations linked with logistics barges, the aim of this paper is to demonstrate their potential to transform offshore breakbulk logistics, especially in the Wind Energy sector.
This paper provides an overview on the UAE’s First Wind Energy Project which was executed during year 2022, the challenges faced, and lessons learned during the project execution. The paper also provide synopsis on the Breakbulk Challenges in the Offshore / Wind Sector and how ADNOC Logistics & Services (L&S) have provided solutions to deal with these challenges. The solutions provided to these breakbulk cargo challenges at Offshore locations are through the provision of Flat-top Cargo Barges.
A Comparative Study of Simplified vs Orcaflex Using an Automated Analysis System
Authors: Sørby B. , Sveen D. A. , Vinther M. L. 
Published: October 2023

Abstract
Lifting large objects through the splash zone may appear simple, but it involves complex physics. A simplified method is available but with inherent limitations. In this study, we compared the simplified method in DNVGL RP-N103 with a comprehensive OrcaFlex analysis for lifting a large suction anchor through the splash zone. The results indicate that the simplified method provides overly conservative weather limitations compared to the OrcaFlex analysis. Additionally, it is evident that the assumptions made in the simplified method are not appropriate for this lift due to significant pitching of the suction anchor.
We compared a new automated web-based analysis system for offshore lifts with the traditional method. The automated system allows for easy, cost-effective, and fast analysis of lifting operations. It significantly improves the ability of analysis engineers to understand and tackle challenging lifting operations. By varying parameters, we optimized the crane-tip position and greatly expanded the weather limitations. Without a fast and reliable system, this optimization would have been difficult and time-consuming. The outcome is enhanced weather limitations and a more efficient operation, thanks to a better understanding of the factors influencing weather limitations.
A Case Study of Using Alternative Engineering Approach for Pipeline Free Span Analysis in the Gulf of Thailand
Authors: Yontsakul B. , Sotananan T. , Trithipchatsakul C. 
Published: October 2023

Abstract
Conventional free span analysis method used for some subsea pipelines in the Gulf of Thailand sometimes results in a substantial number of required free span corrections which in turn impacts the project’s cost and schedule. Alternative engineering approaches are explored to address the issue and reduce the number of free span corrections needed. The main challenges are how to extend the allowable free span length and bring down the conservatism in on-bottom roughness analysis model with acceptable engineering approaches. Customized engineering considerations were applied for two (2) critical subsea pipelines in the Gulf of Thailand where more than fifty free span rectification locations were required according to the conventional free span analysis results. By applying an alternative engineering approach, unnecessary free span correction locations on the two (2) pipelines are filtered out. Only eleven (11) free spans from the originally 69 free spans were deemed to be rectified so as to maintain the pipelines’ integrity throughout their design life. Significant cost savings and project schedule improvement were successfully achieved. Therefore, the objective of this paper is to demonstrate how customized engineering considerations can eliminate the need for unnecessary free span corrections in the field, that is able to reduce the cost and improve project timelines.
