Netherlands-based Coastwise Offshore Services (COS) recently commenced operational sailings of a new windfarm support crewboat built by local company Next Generation Shipyards.

COS Mariner is a sister vessel of COS Master, which was delivered to COS in late 2021.

The crewboat has a length of 27 metres, a cruising speed of 27 knots, and capacity for 30 passengers and five crewmembers plus up to 15 tonnes of deck cargo. A monomaran design was used to combine the improved stability, the greater deadweight, and the lower resistance of a catamaran with the speed, the fuel efficiency, and the reduced roll guaranteed by a monohull.

The vessel may also take on other roles in the oil and gas and civil works industries. These duties include route surveys of pipelines and cables, seabed mapping, inspection, and dredging support.

Norwegian shipbuilder Vard has laid the keel of the second cable-laying vessel in a series ordered from the company by Italian energy and cable systems provider the Prysmian Group.

The vessel will be a near-identical sister of Leonardo da Vinci, which was handed over in 2021. The newer vessel will also be capable of installation in water depths of as much as 3,000 metres and will be equipped with a variety of burial systems including heavy-duty ploughs.

Delivery is scheduled for the first quarter of 2025.

Norway's Havfram Wind has placed an order for a second jackup wind turbine installation vessel (WTIV) in a series from Chinese shipbuilder CIMC Raffles.

The GustoMSC-designed vessel will be fitted with a battery hybrid drivetrain to ensure reduced carbon emissions. The design also incorporates equipment for installing wind turbines with rotor diameters of 300 metres as well as 3,000-tonne monopiles in water depths of up to 70 metres.

The WTIV will be delivered late in the fourth quarter of 2025.

Cyan Renewables selects Norwegian design for future installation vessels

Singapore-based offshore services specialist Cyan Renewables has selected a Norwegian company to design a new series of vessels optimised for installing floating wind foundations.

The new vessels will each feature adequate deck space and crane capacity to meet developments in foundation design, including monopiles and jackets.

In addition, they will also each have low emission capability, using a hybrid power system consisting of dual-fuel engines, shore power connections, and a battery energy storage system. The dual-fuel engines will be capable of running on methanol.
