Subsea Electrification: Subsea Power Evolves

and smaller battery delivered efficiency gains in installation times in addition to vastly improved performance.About four years later, SWE made available the next generation of the battery pack. The SeaSafe II, available since 2017, incorporated lessons learned, reliability improvements, and American Bureau of Shipping (ABS) Certification.  The powerful, pressure tolerant  SeaSafe II battery packs are easy to install in a pressure  balanced oil-filled (PBOF) container, which is smaller, lighter and lower cost than a pressure vessel. In response to industry demand to eliminate the

SBM Offshore Wins AIP for Wind Floater Design from ABS

The classification society American Bureau of Shipping (ABS) has issued an Approval in Principle (AIP) to Dutch-based SBM Offshore for its proprietary wind floater design.The global provider of floating production and mooring systems (FPSO) said that the wind floater is a TLP concept and has been designed for the full life cycle, including in-place conditions, as well as wet tow with the wind turbine installed, and mooring hook-up phase.The AIP demonstrates the successful design of the floater, compliant with ABS’ design standards, said the offshore oil and gas company.“We are very proud

i-Tech Services Earns Inspection Classification Approval

i-Tech Services, a Subsea 7 company, said its Underwater Inspection in Lieu of Drydocking (UWILD) capabilities have been certified to deliver to guidelines set by American Bureau of Shipping, DNV-GL, Bureau Veritas and Lloyds Register.UWILD is required to ensure the structural and operational integrity of a marine asset while on location. i-Tech Services’ inspection division performs these tasks using the latest remotely operated vehicle (ROV) imaging, cleaning and tooling technologies to deliver safer, more cost-effective subsea inspections for all types of assets.Conducting these surveys

Floating Offshore Wind Turbine Design Passes ABS Review

The American Bureau of Shipping (ABS) has completed the design review of the Front End Engineering and Design (FEED) documentation for the VolturnUS, a floating offshore wind turbine (FOWT), developed by the University of Maine Advanced Structures and Composites Center.   “UMaine is pleased that its innovative design became the first floating wind turbine concrete semisubmersible hull to be reviewed by ABS, and found to meet the ABS requirements,” said Dr. Habib J. Dagher, P.E, UMaine Composites Center executive director and principal investigator.    “After 10

ABS Approves First Subsea's Large Scale Steel Forgings

Subsea mooring specialist, First Subsea, has achieved American Bureau of Shipping ABS 2009 Approval for its larger R4 steel forgings up to 562mm diameter. These are the largest diameter forgings to have received the approval, and set the benchmark for Offshore Mooring Accessories with forged bars to the requirements of ‘ABS Guide for Offshore Mooring Chain (2009)’, section 1.9 Special Subsea Mooring Connectors.   The ABS 2009 Certification of Offshore Mooring Chain (updated 2014) specifies the requirements for materials, design, manufacture, and testing of offshore mooring chain and

height, the algorithm computes a probability that the group will turn into a rogue wave within the next few minutes.   “It’s precise in the sense that it’s telling us very accurately the location and the time that this rare event will happen,” said Themis Sapsis, the American Bureau of Shipping Career Development Assistant Professor of Mechanical Engineering at MIT. “We have a range of possibilities, and we can say that this will be a dangerous wave, and you’d better do something. That’s really all you need.”   Sapsis and former postdoc Will

platform moored in 5,310ft (1,620 m) of water in field development in the Gulf of Mexico.   The 23,000-ton spar has been moored by nine Series III Ballgrab ball and taper mooring connectors attached to polyester mooring lines. The connector's male mandrels are manufactured in compliance with American Bureau of Shipping (ABS) 2009 Approval for specialist subsea mooring connectors.     Ball and taper subsea mooring connectors (SMCs) offer a two-part mooring. A connector receptacle is preinstalled, attached by ground chain to a mooring pile. When the spar arrives on-station the ball and

New Ships Join the US Research Fleet

six Navy-owned vessels are charter leased to U.S. oceanographic research institutions. The U.S. ARF includes six Navy oceanographic research vessels known as Auxiliary General Purpose Oceanographic Research (AGOR) vessels. These vessels are purpose-built to commercial standards, classed by the American Bureau of Shipping, and certified by the United States Coast Guard for oceanographic research. In addition to the new ships, the Navy’s research fleet include R/V Thomas G. Thompson (AGOR 23), operated by the University of Washington: R/V Roger Revelle (AGOR 24), operated by Scripps Institution

; Beers Group said the equipment built for this special application incorporates a low temperature glycol chiller system that is lowered and mounted to the habitat supplying air conditioning, dehumidification, refrigeration and CO2 scrubbing. The equipment was designed and constructed to comply with American Bureau of Shipping (ABS) Standards for saturation vessels.   Beers Group Inc. manufacturers the YACHTAIR PRODUCTS line of chilled water air conditioning, refrigeration and generator load bank systems. According to Richard Beers, President, the equipment was not unlike what is built for the yacht

Act and built by Marinette Marine Corporation in Wisconsin, the ship’s primary objective is to support fish, marine mammal, and turtle surveys off the U.S. West Coast and in the eastern tropical Pacific Ocean. Reuben Lasker is classed as a Fishery Survey Vessel (FSV). All FSVs are American Bureau of Shipping (ABS) Ice Classed "C0". The ship has a low sound signature to reduce reactions of fish to the presence of the ship and provides for a low signal-to-noise ratio for acoustic sensors. This allows scientists to study fish populations and collect oceanographic data with fewer
