A joint venture between Schoeller Holdings and Deutsche Offshore Schifffahrt (DOS) has ordered four commissioning service operation vessels (C-CSOVs) for deployment in the offshore wind and other energy sectors. Philipp Maracke, Managing Partner of DOS, noted the market’s need for new players and more ships.
The order was placed with CSSC Huangpu Wenchong Shipbuilding, part of China State Shipbuilding Group. The vessels are scheduled for delivery in early 2027 and will accommodate up to 100 technicians, offering operational flexibility for offshore wind and other energy sectors.
These 96.25-metre-long and 20-metre-wide ships will perform tasks for wind farm installations, turbine manufacturers, grid operators, and oil and gas companies. The design was developed by DOS and Salt Ship Design from Norway.
The ships will feature a modular working deck with over 850 square meters of multipurpose space, a 50-tonne AHC crane with 3D motion compensation, and an integrated offshore gangway system. The design includes a spacious lift for transporting technicians and materials, as well as a 12.4-tonne helicopter deck.
Energy efficiency is a key aspect, with optimized hydrodynamics and an energy-efficient propulsion system expected to reduce fuel consumption and emissions. The ships will have a 1,000 kWh battery pack, shore power connections, and heat recovery systems to minimize their environmental footprint. They are also designed for future retrofitting to operate on methanol and can potentially run entirely on electricity.
Noise and vibration levels on board have been significantly reduced, with the vessels receiving a COMF (C2, V2) class notation. DOS will manage the commercial operations, while Columbia Shipmanagement will handle technical management.
The C-CSOVs will be available for worldwide charters, both short-term and long-term, as stated by Philipp Maracke, Managing Partner of DOS.
“We have applied our experience in building yachts and naval vessels to advance the most common designs,” said Johannes Wolters, Managing Partner of DOS. “By combining a modified layout with modularity, we have created a vessel that is attractive for a wide range of customers without compromising in the offshore wind market.”
