ScottishPower, Oasis Marine Study Proves Feasibility of Offshore Charging

by installing Oasis Power Buoys in the windfarm provides protection from volatile fossil fuel price and the high costs of alternative green fuels, enabling costs to be predictable and in line with the operator’s business model. Its findings were based on the use of three electric CTVs instead of diesel-fueled vessels at a case study windfarm. The study identified potential savings of 140,000 tonnes of CO2 emissions and fuel saving costs of around £15 million over the windfarm’s anticipated 25-year lifetime.The findings are being shared through the Operation Zero initiative, which was

Naturally Quiet

The Arctic’s bowhead whales can live for over 200 years. Imagine what they might hear in that time: screw propellers were only just being used to power ships 200 years ago, and diesel engines appeared some hundred years after that.The underwater radiated noise of shipping has grown globally, but the Arctic is a special place. It has been partially shielded from shipping noise. Sea ice shields and diffuses underwater sound, so belugas and narwhals, for example, can find shipping noise particularly disturbing – perhaps leaving the area for days. There have been reports of belugas

Newbuild USV Challenger Getting Ready for Remote-Controlled Subsea Work

.The vessel - named USV Challenger - will shortly arrive at DeepOcean’s subsea base at Killingøy in Norway, where it will undergo trials of its launch and recovery system (LARS) for the onboard ROV.The USV Challenger is 24 meters long and 7.5 meters wide. It is equipped with a hybrid diesel-electric propulsion system and a battery package that allows the uncrewed vessel to operate offshore for up to 30 days without charging or refueling.Designed by DeepOcean, the LARS consists of an electrical winch, a sheave wheel trolley, kicker and rear hatch.Following maritime authority approvals

ASL Environmental: Tidal Currents Study Underway in Newfoundland and Labrador

successful completion of an initial multi-week study to measure tidal currents in collaboration with the Nunatsiavut Government and Oceans North. This initiative aligns with the Nunatsiavut Energy Security Plan to explore clean, renewable energy solutions for coastal communities and reduce dependence on diesel-generated electricity.Current transect surveys were initially carried out with Acoustic Doppler Current Profilers (ADCPs) over the broader study area. ADCPs were then deployed on moorings at three strategic locations within the Rigolet Narrows waterway and recovered in September 2024. The data from

transport vehicles to worksites. By removing the need for surface ships, the Loggerhead all-electric uncrewed system has the potential to vastly reduce the emissions, cost and risk of underwater robotics operations. Per vessel displaced, Loggerhead will remove the equivalent emissions of 4,000 petrol or diesel cars," the company said in a statement
