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

That’s really all you need.”   Sapsis and former postdoc Will

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

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

Wärtsilä’s Propulsion CMS recognized by 3 Classification Societies

 Wärtsilä has received service level recognition for its Propulsion Condition Monitoring Service (PCMS) by DNV-GL. Wärtsilä is the first company to attain this type of recognition from three of the major classification societies, namely the American Bureau of Shipping, Lloyd’s Register, and DNV-GL. The approval, which was received in February 2014, means that surveyors from the classification societies may rely on Wärtsilä’s PCMS when assessing propulsion equipment. This eliminates the need for the compulsory five-year internal inspection, which often

Infrared Offshore Equipment Windows DNV Approved

IRISS VP and CAP Series industrial grade infrared windows for thermal inspection say they are the only windows to be approved by DNV for use in marine and offshore areas.  In combination with existing Lloyds and ABS (American Bureau of Shipping) credentials, DNV accreditation makes these products the perfect choice for preventative maintenance of electrical equipment in line with NFPA 70E electrical safety standards and SOLAS regulations. The breadth of the IRISS product range covered by the newly granted DNV approval is extensive. The VP range comprises seven product variations to meet the
