Damen completes maintenance work on Deep Arctic DSV

Damen Shiprepair Amsterdam has completed maintenance work on the diving support vessel (DSV) Deep Arctic.

 

Damen said on the 26th June that a substantial proportion of the maintenance work was done in dry dock.

 

According to the company, the 156-metre, TechnipFMC-owned, Deep Arctic came in for a main class renewal docking and maintenance, including the renewal of the steel plates to its box coolers.

 

The yard also performed a large number of works at considerable heights.

 

Damen conducted precise removal, overhaul, inspection, and installation of the coolers. The works required renewing the box cooler steel plates included cropping the old sea chest plates and replacing them with new steel plates.

 

Once the works were complete, all the interior areas affected, including the ballast water tanks, forward tanks, cofferdam tanks and hull plates, were treated with a coating programme.

 

The yard also blasted and painted all the repaired sea chests and 16 additional forward sea chests.

 

During the vessel’s stay in dry dock, a complete thruster overhaul including upgrades to its tunnel, retractable, and Azimuth thrusters was done.

 

The propeller shaft and centre-line rudder also had their ten-yearly overhaul.

 

These operations all took place in close collaboration with the owner’s specialists, Rolls Royce, and OEM.

 

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.

 

The rest of the works included repairs to the gangway and load tests on the accommodation ladder and platform as well as maintenance to two cranes and painting the main and navigation masts and the helideck support structure.
