Kongsberg Maritime has secured $73.3 million contract from Fujian Mawei Shipbuilding in China to supply range of equipment for a new fleet of 10 platform supply vessels (PSVs) being built for Greek shipowner Capital Offshore.Under the contract, Kongsberg Maritime will supply all propulsion, automation, and energy systems for the 95-metre vessels of MMC 897 CD design.The Kongsberg Maritime electrical system on these vessels will enable optimal operation through the Energy Storage System (ESS).

A study published by Norbert Bulten, Product Performance Manager at Wärtsilä, has demonstrated that “there is more in life than the straight-sailing, calm water condition.”The research was carried out within the EU-funded CHEK project and involved full-scale CFD simulations that focused on the impact of rudder steering and vessel motion.The study compared a gate rudder concept to a conventional semi-spade rudder for a Kamsarmax bulker.Typically, a rudder is placed behind the propeller, where the movable part can be a part (semi-spade) or the complete rudder section (full-spade).

A series of four zero-emission and autonomous ferries, to be built by Turkish Tersan shipyard for Norwegian ferry operator Fjord1, will be propelled by Schottel’s EcoPellers.The double-ended vessels will be the first of their kind in the world, with Norwegian HAV Design tasked to deliver the ship design and an engineering package.Two electrically driven Schottel EcoPellers type SRE 340 will be installed in each of the 120 meter long and 18.60-meter-wide vessels.The L-Drive variant or “embedded L-Drive” significantly reduces the installation height of the thrusters…

Becker Marine Systems introduced two new products at SMM which are designed to optimise vessel hydrodynamic performance: the Becker Daggerboard and the Becker Steering Gear.The Becker Daggerboard is an anti-leeway fin designed for ships equipped with modern wind- assisted propulsion systems (WAPS). When using WAPS, the desired thrust ahead components drive the ship. Depending on the wind direction, there can also be stronger or weaker lateral force components leading to leeway from the desired course.

Brunvoll has been chosen to supply azimuth propulsion thrusters and thruster control systems for Norled’s four next hybrid ferries.The vessels will service the routes between Stokkvågen, Lovund, and Træna in Norway. Designed by LMG Marin, the vessels will be built at the Tersan Havyard Shipyard.Norwegian ferry operator Norled has won the contract for the routes based on a 90% reduction in emissions.Each ferry will have a battery capacity of 8000 kWh, and therefore the largest battery capacity compared to other ferries in Norway.The routes support traffic between Stokkvågen and Lovund…

Kongsberg Maritime has secured a contract to design and a equip a 10th hybrid chemical tanker for Danish operator Tärntank.The new Tärntank vessels will reduce carbon emissions using a combination of clean technologies.The wind-assist technology will be installed on the latest four vessels ordered, and this feature alone is expected to reduce emissions by up to 19%. The new vessels will have an Energy Efficiency Design Index close to 40% below the 2025 Phase 3 requirements.The 15…

A containership transiting the Pacific Ocean lost hydraulic oil and propulsion after its propeller blade cracked, according to a report from the National Transportation Safety Board (NTSB). A blade on the vessel’s controllable pitch propeller system did not meet manufacturer design specifications, the investigation found.The Matson containership Maunalei was travelling to Portland, Ore., from Anchorage, Alaska on August 11, 2022, for drydock repairs when the crew intentionally shut down the main engine due to problems in the controllable pitch propeller system…

There is hydrodynamic solution that delivers multiple benefits for ship owners facing increasingly tough regulatory requirements and rising operational costs, writes Dr. Batuhan Aktas*One area of ship operations that has attracted much attention in recent years due to the possibilities it represents for emissions reduction is that of cavitation. During ship operations, cavitation occurs because of vortices that build up and cause bubbles to collapse under the ship’s propeller. The results of this process include increased noise, vibration and energy usage.
