Diving works supporting a cable repair project at Prinses Amalia wind farm (included J-tube replacement).
C-Ventus Offshore Windfarm Services (DISA’s OWF department) carried out diving works in support of a cable repair project at the Prinses Amalia wind farm. The scope was explicitly described as diving support for a cable repair campaign and was executed under a client relationship with Jan de Nul, who was identified as the main contractor for the project. The diving works supported an offshore cable repair intervention that included replacement of a J-tube, which is a key cable interface component used to guide and protect cables where they enter a foundation or substation structure. C‑Ventus’ role therefore covered subsea access and diver-enabled tasks that typically include inspection and preparation of the worksite, support to removal and reinstatement activities at the cable interface, and verification/assistance during repair and reinstallation steps, all conducted under offshore safety and operational controls. Because the works were described as part of a cable repair project at an operational wind farm, this engagement fits within cable operations and maintenance (O&M) support rather than initial construction. The contractor explicitly thanked both Eneco (the wind farm owner) and Jan de Nul (its direct client) for the safe execution, linking the work to Prinses Amaliawindpark as a specific project asset.
