Offshore Turbine Services (OTS) are, in conjunction with Seazip Offshore Service BV, providing a crew transfer vessel (CTV) – Lieutenant P – for the construction of the 42MW Tahkoluoto offshore wind farm in Finland.
Initially, the vessel worked for the foundation installation contractor, supporting the marine civils aspect of the construction phase.
Once that was completed, the wind farm owners took the opportunity to place the vessel on hire to assist with the next phase of the construction supporting the turbine manufacturer techs on site, OTS said.
The OTS vessels are particularly suited for this close inshore, shallow draft working as they use Rolls-Royce jets for propulsion, OTS said.
The vessels are also very fuel efficient and their moveable wheelhouses allow them to be configured for a variety of tasks including generator refuelling, blade inspection and repair and marine civils work support.
This is the first collaboration between OTS and Seazip and the companies are looking forward to working together in the future.
The Tahkoluoto offshore wind farm comprises 10 4.2MW Siemens wind turbines installed off Pori.
The wind farm is scheduled for commissioning in September 2017.
