Schoeller Holdings and Deutsche Offshore Schiffahrt have identified a pressing need for more versatile offshore vessels, leading to their recent joint venture and the order of four innovative Construction Commissioning Service Operation Vessels (C-CSOV). These vessels are designed to address the increasing demand for support ships in the global energy market, particularly as Europe advances its offshore projects and emerging sectors develop in Japan, Taiwan, and beyond.

The four new vessels will be constructed by China’s CSSC Huangpu Wenchong Shipbuilding, with deliveries scheduled to begin in early 2027. Columbia Shipmanagement will provide technical services, and the vessels will be available for charter in both the offshore wind and energy markets.

Philipp Maracke, Managing Partner of Deutsche Offshore Schiffahrt, emphasized the urgent demand for new vessels in the energy sector, stating, “We will charter out the C-CSOVs worldwide, both on the spot market and for long-term contracts of up to 15 years.”

These vessels represent a significant innovation, designed not just for offshore wind turbine support, but also adaptable for various applications, including services for grid operators and the oil and gas sector. The C-CSOVs will be capable of performing tasks both above and below the water, making them exceptionally versatile.

With a length of 96.25 meters and a beam of 20 meters, the vessels will accommodate up to 100 technicians. The design focuses on hydrodynamics and features energy-efficient propulsion and systems, including a 1,000 kWh battery pack and shore power connections. Additionally, they are prepared for methanol fuel, ensuring they meet future energy requirements.

Key features include an expansive, modular working deck of over 850 square meters and a 50-tonne AHC crane with integrated 3D motion compensation, enabling a range of activities from cable repairs to light construction work. The integrated offshore gangway system allows for efficient access to platforms 12 to 30 meters above the waterline, with a dedicated lift for transporting technicians and materials swiftly. The vessel will also feature a 12.4-tonne helicopter deck and capabilities for remotely operated vehicles (ROVs), with options for modular cable repair systems.

Developed in collaboration with Norwegian firm Salt Ship Design, this innovative vessel design aims to fulfill the diverse needs of the offshore market while maintaining high operational capabilities.
