The International Association of Classification Societies (IACS) has developed a Unified Requirement (URH1) covering the release of ammonia from the onboard systems for bunkering, storing, preparing and using ammonia as fuel.IACS URH1 aligns with the Recommendations from U.S. National Institute for Occupational Safety and Health (NIOSH) and establishes that an ammonia concentration of 300 ppm or more is immediately dangerous, and a concentration of 25 ppm or more is dangerous if the exposure is longer than eight hours.Additionally…

Mitsui O.S.K. Lines (MOL) has been awarded an approval in principle (AiP) by ClassNK for a design of Floating Storage and Regasification Unit (FSRU) for ammonia.The ammonia FSRU has been jointly developed by MOL and MHI Group’s Mitsubishi Shipbuilding.Obtains AiP for Ammonia FSRU Design - A Step Toward Safe Utilization of Ammonia for DecarbonizingThe AiP gives MOL further assurances in its design and development of ammonia FSRU, the technology, which enables a large scale of storage and distribution of seaborn ammonia.Introducing the ammonia FSRU concept…

DNV GL said it has acquired ComputIT, a specialist independent company for Computational Fluid Dynamics (CFD) software and R&D. ComputIT develops unique high-end technology for simulating fires, explosions and gas dispersion. “This acquisition brings us world-leading capabilities in the CFD domain,” says Are F. Tjønn, CEO, DNV GL - Software. With its roots in the offshore sector, ComputIT has also served onshore oil and gas, power generation, chemical, transport, maritime, and construction industries. It has been engaged by governmental bodies for investigation of fire accidents.

The first of three new dual fuel RAstar 4000-DF class extreme escort tugs, the Dux, has been delivered to Østensjø Rederi AS by Spanish shipbuilder Astilleros Gondán S.A. Designed by Robert Allan Ltd., the 40.2 meter vessel is the first of a three boat order from Østensjø for severe weather operations at Statoil's Melkøya LNG Gas terminal at Hammerfest in the extreme north of Norway. These escort tugs will conduct approximately 300 LNG ship escorts annually, assist with berthing operations and will be maintained in readiness for emergency services such as long line towing…

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 push to standardize their delivery globally, up from 55% in 2015 and 52% in 2014. The most common strategy for maintaining innovation with lower budgets is to increase collaboration with other industry players (45%).

To meet the rapidly growing demand for a wide variety of LNG related services, DNV GL has established a group of LNG experts in North America. In addition to deep LNG expertise, the Houston-based “LNG Solutions Group - Americas” is also experienced in all business, risk and regulatory matters specific to the North American market. With the increasingly strict regulation of sulphur emissions in force next year and the already tightened Emission Control Area regulation for the U.S., ship owners are likely to feel more pain by the rising fuel prices.

Petrobras’ P-55 Floating Production Unit (FPU), the largest and the first of this kind entirely built in Brazil, is on its way to the Roncador Field, Campos Basin, where it will be installed in a water depth of 1,790 metres. The column stabilized semi-submersible has a capacity of 180,000 bopd and 6,000,000 cu m of gas. The unit is classed by Bureau Veritas. BV group companies also provided a wide range of verification and support services which made the major project possible.

The Type-Approved BALPURE ballast water treatment system from Severn Trent De Nora has received type approval from classification society Bureau Veritas (BV) for its full range of standard ballast water treatment systems that can treat ballast water flow rates of up to 5,000 m3/h. Standard systems can be supplied as multiple sets to treat higher flow rates. The type approval was granted by BV following stringent review of the BALPURE system per BV rules and guidelines along with the guidelines contained in the IMO Resolution MEPC.174(58).

ABS is currently involved with the review of or being considered for the selected class society for several Floating LNG (FLNG) and Floating Storage and Re-gasification Unit (FSRU) concepts. “We’ve been approached by leading energy operators to help them evolve gas technology that has typically been developed for land-based facilities,” said Ken Richardson, ABS Vice President Energy Project Development. Richardson pointed out that the recent increases in the size of LNG carriers may create commercial challenges for the continued flexible operation of some of the existing LNG carriers. “LNG carriers are some of the best maintained vessels that can be found,” Richardson pointed out. “Strict maintenance regimes mean these ships may have many years of serviceable life ahead of them.
