LLOG Taps ABL for Marine Warranty Services at Salamanca Project in Gulf of Mexico
subsea development of the Salamanca project in the U.S. Gulf of Mexico.The Salamanca development project envisages the build-out of the Leon and Castille oil fields in water depths ranging from 1,800 to 2,000 meters.The subsea portion of the project includes the installation of three infield subsea pipeline systems, as well as the design and fabrication of subsea structures. The pipelines will run from the wellsite to the Salamanca floating production facility.Under the terms of the contract, ABL will provide technical document review and approval of all project critical procedures, drawings and documentation
Hydrogen Pipelines: DNV Launches Phase 2 of H2Pipe Project
; DNV said.DNV said that industry players were exploring ways of transporting hydrogen as an additive or replacement for natural gas, but "currently, offshore pipeline codes insufficiently cover the transport of hydrogen or hydrogen blends by offshore pipelines."The DNV standard for subsea pipeline systems (DNV-ST-F101) includes hydrogen as a listed transport product, but additional considerations are required to meet the target safety level for an increased use of hydrogen. A special concern in this respect, according to DNV, is the potential detrimental influence of hydrogen on resistance
Carbon Capture & Storage: A New Lease of Life for Submarine Pipelines?
, project manager on the project. “For C-Mn steel pipelines, components and associated welds, it is well recognized that hydrogen may promote hydrogen embrittlement which could have an adverse effect on the pipeline system integrity, and hence impacting both the design and operation of such pipeline systems. There are still uncertainties related to how hydrogen gas or blends may affect the mechanical properties of these materials.”A first revision was shared in December 2021, but there are still uncertainties around how hydrogen gas or gas blends may affect mechanical properties of pipelines
Busy Summer for Pipeline Tech Firm STATS Group
pipeline isolation projects in its 23- year history.STATS said that it had, during the 2021 summer shutdown season, supported six separate Tecno Plug isolation deployments in the UK North Sea, on pipelines ranging from 20” to 36” in diameter. "The projects were on critical pipeline systems on behalf of multiple clients, with the isolation periods ranging from 10 to 45 days," the company said.Isolation activities were carried out onshore and offshore at various locations and included the use of STATS Remote Monitoring System, which allowed Tecno Plug isolation tools to be
Swire Seabed Orders a HUGIN AUV
;s CEO Arvid Pettersen explained. “We believe that the future of inspections and subsea survey is indeed autonomous and we are excited to be at the forefront of an evolving industry.”In October 2018, Swire Seabed completed its first commercial autonomous inspection of offshore pipeline systems for Equinor using Kongsberg Maritime’s HUGIN AUV and, shortly after in December 2018, was awarded a frame agreement with Equinor for provision of offshore survey services.Now, the firm will have a HUGIN AUV of its own. Due for delivery in 2020, the vehicle will be rated to 4,500 meters
Autonomous Subsea Pipeline Inspection
Swire Seabed said it completed autonomous inspection of offshore pipeline systems for Equinor in October 2018 utilizing Kongsberg Maritime’s Hugin autonomous underwater vehicle (AUV).The inspections were performed on three pipelines between Kollsnes and Troll A. In total, 180 kilometers of pipeline were inspected over two AUV dives.The inspections were undertaken with the subsea vehicle in autonomous mode, with a small surface vessel accompanying the AUV to provide positional updates to the vehicle and act as a communications relay between the AUV and the Control Center at Swire Seabed’s
Project to Standardize Subsea Processing Progressing
the vendors and oil companies, which will enable the future large-scale use of subsea boosting.” Morgan Harland, General Manager, Subsea & Pipelines, Woodside, said, “Through innovation and collaboration, Woodside aims to deliver outstanding performance of our subsea and pipeline systems throughout the entire lifecycle. The standardization of subsea processing JIP and its initial focus on subsea pumping hits the mark with standardized guidelines being developed for subsea processing modules and interfaces that are efficient, reliable and readily installed and serviced. We use
Forum Receives Order for Three ROVs
this year. New Orient Marine’s new build, multipurpose ice-class vessel has been designed to operate in ambient temperatures as low as minus 30 degree Celsius. The first project for the new vessel will involve subsea intervention, inspection, maintenance and underwater welding of existing gas pipeline systems. Cris Gaut, Forum’s Chairman and Chief Executive Officer, said, “The award demonstrates Forum’s capability for working with our customers to provide solutions tailored to their specific needs. It also validates our strategy of providing ongoing first class engineering
Standardization for Cost Effective Pipeline Innovation - DNV GL
-40 years of standardization paves way for cost efficient offshore pipeline systems - Growing global energy demand and requirements for additional pipeline capacity are driving the pipeline segment. However, pipeline related innovation is prioritized by only 4% of senior oil & gas professionals, according to research by DNV GL, the technical advisor to the oil & gas industry. Further, the research shows that nearly one in five oil & gas companies (18%) do not have a strategy in place to maintain innovation. Six in ten (61%) respondents agree that operators will increasingly
