Deal Analysis

The commencement of construction for the DO Joule, the first of a four-ship series of Construction Commissioning Service Operation Vessels (CSOVs), marks a significant development in the offshore wind infrastructure sector. This project sees Deutsche Offshore Schifffahrt as the developer, with the vessels ordered by Schoeller Holdings and being built at CSSC Huangpu Wenchong Shipyard in China. This initiative directly addresses the growing demand for specialized maritime assets crucial for the installation, commissioning, and maintenance phases of offshore wind farms. This deal is notable for its focus on expanding critical support infrastructure for the rapidly expanding global offshore wind industry. The development of these CSOVs, designed by Salt Ship Design and involving Columbia Shipmanagement as a partner, underscores an international collaborative effort to enhance operational capabilities within the sector. As a development-type deal, currently announced, it signals a forward-looking investment by Schoeller Holdings and Deutsche Offshore Schifffahrt into long-term operational capacity, despite the undisclosed value. The construction in China highlights the global supply chain dynamics prevalent in large-scale infrastructure projects.

The steel-cutting ceremony for the vessel took place on 5 March. The vessels are 96.25-metre-long and 20-metre-wide. Subsequent vessels will be handed over at three-month intervals. The ships will feature a gangway capable of providing horizontal access to platforms between 12 metres and 30 metres above the waterline. The vessels will also be equipped with dynamic positioning capabilities, a HiPAP hydroacoustic positioning system and a 12.4-ton helicopter deck. Each vessel will have a modular working deck with 800 square metres of unobstructed space and a crane that can be reconfigured within 48 hours between a 50-ton active heave compensated setup and a 10-ton 3D-motion-compensated mode. Accommodation onboard will house up to 95 technicians.
