Eidesvik Equips Fleet with Energy Efficiency Software

The Norwegian offshore shipowner Eidesvik has signed a contract with Yxney Maritime for the use of Yxney's Maress energy efficiency software on its vessels, as a step towards further emissions reduction.Maress is a cloud-based system using available data produced by the vessels to create insight and transparency about the fuel consumption and emissions from operations. As part of the agreement, the software will initially be deployed on six offshore vessels owned by Eidesvik."We are excited to add Eidesvik to the list of ship-owners using Maress. They´re known for constantly

In environmentally sensitive areas, stored energy, supported by clean shore power connected via ABB technology, will enable emission-free operation.“This is a very sophisticated live fish carrier whose energy efficiency contributes to sustainability in the food supply chain it serves and in its working environment,” said Sindre Sætre, head of ABB Marine & Ports business in Norway.  “Building on years of ABB experience in hybrid power solutions, we are proud to make a first delivery

MacArtney Puts First All-Electric eLARS into Production

.In line with customer demands, to meet the green agenda for more eco-friendly products, the all-electric eLARS, developed in collaboration with MacArtney customers, features a number of eco-friendly benefits. Zero pressurized oil over water significantly reduces the risk of oil spillage, and energy efficiency is improved by more than 30% compared to hydraulic systems.The new eLARS aims to provide a low cost of ownership with Plug-and-Play mobilization, maintenance work reduced by up to 50% and cost-efficient spares with minimum lead times. Designed with a high degree of integrity, the actuation

Simmons. “Through innovation we can help unlock the potential of the ocean to provide both energy and water across the country.”The DISCOVER stage, first announced at the White House Ocean Science and Technology Summit in November 2019, cast a wide

Electric Motor Selection for Underwater Vehicles: Considerations of Partial Load Efficiency

manufacturers typically provide enough information about fuel consumption across the engine’s RPM and power range so that we can reliably predict fuel use for any application. A plot of this distribution is often called a “fuel map”, but let me have you think of it as an output-to-input energy “efficiency map”.Unfortunately, we have a completely different circumstance when using PMSM drives. Confusion can arise because the generated benefit of the motor and the fuel used by the motor share the term “power” – one being the output mechanical shaft power (that

; Long Range 2 (LR2) product tanker vessel, said the company.The Rotor Sails deliver auxiliary wind propulsion to the vessel - which have operated in conditions ranging from tropical climate to arctic conditions in Europe, Middle East, Asia and Australia – resulting in the optimization of energy efficiency and a reduction in fuel consumption.The Rotor Sails were installed onboard Maersk Pelican in August 2018. As part of the test, the aggregated total fuel saved from 1 September 2018 to 1 September 2019 was 8.2% savings. This is equivalent to approximately 1,400 tonnes of CO2. The savings were
