Damen has developed a new concept vessel – OSV 9020
Built around a stable platform with station-keeping capability, low carbon emissions and flexibility to add mission-specific tools, Damen’s OSV 9020 vessel is designed to handle offshore tasks at both surface and subsea level.
The company said the OSV 9020 was conceived as a standard product, drawing upon proven technology, that can be tailored to individual requirements through modularisation.
The new concept was born out of necessity, according to Damen design engineer Mark Couwenberg. He said the company was approached by several operators who were “all looking for slightly different offshore capabilities... similar enough that their requirements could be met with a conceptual standard platform”.
"The vessel can be fitted with a moonpool-deployed saturation dive system to allow diving operations [utilising] an offshore crane, a stern A-frame and an offshore access system. The vessel can also act as a submarine rescue vessel and comes with a helicopter deck integrated in the design," he said.
OSV 9020 provides living space for 120 people on board and the interior is designed with working areas separate from living space.
Mr Couwenberg said the design was intended to ensure the accommodation spaces were "both functional and comfortable".
The vessel has been primarily designed to operate on dynamic positioning with the hull, superstructure and thruster layout designed for DP. The vessel’s profile minimises wind catch and four identical azimuthing thrusters are arranged symmetrically – two on the stern and two on the bow – for station-keeping performance and avoiding high noise levels in crew accommodation.
Diesel generators on board are supported by a battery pack and the electric system operates with closed bus-ties. The vessel is fitted with a hybrid power generation system to reduce emissions, and Damen said the vessel can also be configured to operate on green methanol produced from biological waste streams.
