Damen Shiprepair Amsterdam has completed maintenance programme on the diving support vessel ‘Deep Arctic’.
The 156-meter, TechnipFMC-owned Deep Arctic came to Damen Shiprepair Amsterdam (DSAm) primarily for a main class renewal docking and for maintenance including the renewal of the steel plates to its box coolers.
The works required renewing the box cooler steel plates included cropping the old sea chest plates and replacing them with new steel plates prefabricated in the DSAm steel workshop and machine shop.
Once the works were complete, all the interior areas affected, including the ballast water tanks, forward tanks, coffer dam tanks and hull plates, were treated with a coatings programme. The yard also blasted and painted all the repaired sea chests and 16 additional forward sea chests.
Whilst the Deep Arctic was in the dry dock, it also over went a complete thruster overhaul including upgrades to its tunnel, retractable and Azimuth thrusters, six in total. The vessel’s propeller shaft and centre line rudder also had their 10-yearly overhaul.
Additional associated works included the fabrication of new piping for both tunnel thrusters, renewal of the lower gear units, repairs to the rudder stock actuator and the overhaul of the stern tube seal boxes.
To finish off, the yard also performed repairs to the gangway and load tests on the accommodation ladder and platform. Maintenance was also done to the structures of cranes no.1 (400T) and no.2 (58T), which included the removal of rust and painting the main and navigation masts and the helideck support structure.
