Subsea Cable Gripper Redesigned for Longer Deployments

Gripper for up to 20 days before recovery to the surface is a significant boost to the gripper’s utilization in cable and umbilical recovery campaigns,” said Keith Elliot, managing director, Allspeeds.Developed in consultation with international certification body and classification society, DNV GL, the CRT200 Cable Retrieval Tool is the only cable and umbilical retrieval tool to meet the exacting design codes and standards for marine operations, and offshore and platform lifting appliances. Specifically, the CRT200 satisfies the requirements of DNVGL-ST-N001 Marine Operations & Marine

codes for field joints are FJFD for filler damaged; FJFE (filler exposed or loose wrapping) and FJCC (corrosion coating exposed). The coded “events” accrue and help form a readable, accurate pipeline report.It isn’t just Ecotone generating pipeline repair codes. Class flag bearer, DNV GL, has for years been pushing its RP-FF11e recommended practice code for subsea pipeline repair. It covers fittings like clamps, couplings, T-branch connections and isolation plugs, including the welded connections of these.That’s where Ecotone can help: by scanning miles of connections, en masse

TMS to Use 3D Printers for Submarines

, 83 percent of the weight was saved – from 14 down to 2.1 kilograms.In summer 2019, the thyssenkrupp TechCenter Additive Manufacturing was the world's first producer of 3D printed components for maritime applications to receive manufacturer approval from the renowned classification society DNV GL. The certificate guarantees the material properties of the finished component in accordance with specified standards issued by independent testing bodies.In future, thyssenkrupp Marine Systems plans to use 3D printers mainly in manufacturing the parts that are required in small batches for a submarine

10 Tech Trends to Impact Shipping Industry

A new report has identified the ten technology trends, and their associated risks, that will shape industry and society in the coming decade.The rapid advancement of digitalization is behind many of the trends, profoundly challenging our personal and societal assumptions, according to DNV GL, the global risk management and quality assurance company.The report 'Technology Outlook 2030' said that the relationship between humans and technology is switching, with humans increasingly augmenting the decisions of artificial intelligence, rather than the other way around.For example, in the next

DNV GL Issues Guidance for Subsea Welding

A new recommended practice (RP) to standardize operator requirements for welding and inspection of subsea equipment has been published by DNV GL.DNVGL-RP-B204 “Welding of subsea production system equipment” provides harmonized operator requirements and that will ensure consistency in the fabrication of subsea pressure retaining equipment such as wellheads, Xmas trees, manifolds and jumpers.The RP has been published following a joint industry partnership (JIP), initiated by DNV GL in February 2017. The JIP involving 12 operators, contractors and fabricators addressed supply chain uncertainty

to ensure another decade of smooth operation. However, as the vessel is in dry-dock, this presents a great opportunity to look at ways to improve the system even further.“A full recertification process is necessary every ten years, and this is to ensure that the vessel continues to comply with the DNV GL standards,” says Mark Timmermans, Account Manager at Bosch Rexroth. “Fugro then asked us what we would recommend for the hydraulics system going into the future. Generally speaking, they want another ten years of smooth operation, improve up-time, and more specifically asked for some

DNV GL RP for Subsea Pumping Systems

A new DNV GL recommended practice (RP) aims to help the oil and gas sector to deliver more cost-efficient and environmentally friendly subsea processing for improved hydrocarbons recovery. DNVGL-RP-F303 Subsea pumping systems provides a comprehensive specification for subsea pumping systems and complements existing industry standards.DNVGL-RP-F303 has been published following a joint industry project including participants from subsea operators Equinor, Petrobras, Shell and Woodside in addition to four major systems suppliers; Aker Solutions, Baker Hughes, OneSubsea, and TechnipFMC. The project sought
