Vattenfall has issued a call for competition seeking a service operation vessel (SOV) for the DanTysk and Sandbank offshore wind farms in Germany.

The selected party will provide an SOV to allow accommodation and transfer of technicians via suitable gangway solutions to turbines for scheduled maintenance during the spring and summer campaign of 2021.

The vessel will be based in the Danish Esbjerg harbor.

Vattenfall will consider as SOV any DP2 vessel with a gangway that meets all technical, HS and EnSu employers requirements.

The expected commencement date of the contract is 1 May 2021 with a four-month duration and option to extend three times by one month.

The duration of the qualification system is from 23 December to 14 January 2021.
