‘Terschelling’ arrived at Damen Shipyards Den Helder for annual and corrective maintenance, and testing however after dry-docking, it was discovered extensive repairs were required.

Annual maintenance

Testing and annual certification checks were carried out to the MOB davit, to the lifting and lashing equipment, the safety equipment including fire-fighting equipment and to the navigation instruments and radio. In addition, the diesel-fired heater was also serviced.

Buoy laying crane

Major work was carried out to ‘Terschelling’s’ buoy-laying crane. This was dismantled by Damen Shipyards Den Helder in conjunction with drive and control technology specialist Bosch Rexroth.

The hydraulic pumps and cylinder were then taken to Bosch Rexroth’s factory for servicing and repairs while Damen Shipyards Den Helder checked the crane’s joints and clearances. The crane was then reassembled and tested at 125% load, witnessed by the class certification representative.
