JRC Says Its Wave Analysis Tool Helps Prevent Container Spills

heavy weather conditions over recent months, impacting the ocean environment and adding a large extra cost expense for shipping companies.Among many factors leading to the problem is heavy rolling and pitching of the ship that causes containers to lose their stability and fall overboard. Marine electronics company JRC said its navigational radar JMR-7200/9200 includes a Wave Analysis function made available through a software upgrade.The JRC Radar Wave Analysis function is developed to measure wave height, direction and length. Even in rough seas, clearly presented wave information provides navigational

presented was to measure speed through water accurately from a foiling sailing machine – something that has not been done before now,” says Torstein Pedersen, Development Engineer at Nortek.  The success of this solution was very much cooperative: Nortek provided the modified electronics and operational advice, while the INEOS TEAM UK technical team ensured an optimized installation in the foil.  “We are familiar with an iterative process for these custom solutions, but in this instance I think we were all surprised how well it worked right out of the gate. When we

boats (RIB) or via a small winch or hand winch. Over half of the units can be operated by just one person, making them extremely practical and versatile.Unique Mounting SolutionUsually, a Seabird 32 carousel water sampler frame carries 12 bottles but in this case, due to a higher mounting of the electronics – with two pipes instead of a frame – it only holds 10 bottles. This design's benefit is a reduced lifting height by 0.5 metres, meaning the carousel is still manageable on smaller boats with smaller winches. Moreover, the mounting solution saves time and money on the annual calibration

found in polymetallic sulfides, or "black smokers", which are formed when sea water reaches magma, heats up and is flushed back to the seabed carrying dissolved metals and sulfur.The expeditions have also discovered high concentrations of lithium and the rare earth metal scandium used in electronics and alloys in manganese crusts which grow on bedrock, the Directorate said.Norway has mapped these deposits along the Mid-Atlantic Ridge between Jan Mayen Island and the Svalbard archipelago in the Norwegian Sea as far as 700 kilometers (435 miles) offshore.TimelineOnce completed, the government

Putting Power on the Seabed: Edging towards a Subsea Powerhouse

Compact Pump aims to come with integrated VSDs, mitigating the need for full-on ‘type-3’ (i.e. supply, transmission, and distribution).The goal is to provide power, ranging from 750 kW to more than 11MW, to subsea systems, from pumps to compressors.This includes the power equipment and electronics required, to avoid having to make brownfield modifications on existing topsides and/or enable entirely subsea developments to shore. The benefits are touted as a more scalable and flexible architecture.However, the much longer step-outs that have been targeted have bigger challenges, in terms

Elbit Systems to Buy Sparton for $380 Million

Israel-based international defense electronics company Elbit Systems has signed an agreement to buy maritime defense contractor Sparton for $380 million.  Elbit said Wednesday that its U.S. subsidiary Elbit Systems of America had signed a definitive agreement with an affiliate of Cerberus Capital Management, L.P. for the acquisition of Sparton. Sparton Parent, Inc.—formerly known as Striker Parent 2018—an affiliate of Cerberus Capital Management, L.P. bought Sparton in March 2019.The Elbit transaction is conditioned on various closing conditions, including receipt of U.S. regulatory

HII Delivers REMUS 100 to the German Navy

Huntington Ingalls Industries (NYSE: HII) delivereda new REMUS 100 Unmanned Underwater Vehicles (UUVs) to the German Navy. The vehicles will be used to expand the German Navy’s current fleet of REMUS 100 UUVs used for mine countermeasure (MCM) operations.The new REMUS 100 UUVs have advanced core electronics and endurance of up to 12 hours. Built on the REMUS Technology Platform, the vehicles are open architecture and have enhanced modularity.“We value our ongoing partnership with the German Navy and are proud to help enhance their national security capabilities,” said Duane Fotheringham

core is a pair of high-dynamic range scientific CMOS (complementary metal–oxide–semiconductor) cameras, each with 2,560 x 2,160 pixel resolution – double that of SeaXerocks. These are mounted in a 4000 m-rated titanium housing, optimized for AUV mounting, that also includes low-power electronics to control the lasers, strobe illumination, communication, data acquisition and processing.Like SeaXerocks, BioCam uses laser lines, but has two lasers, which are pulsed in synchronization with the camera. These were installed on the NOC’s Autosub6000 to provide an ~8 m swath able to cover
