150 tonnes of steel used in retrofit

Damen Shipdock Amsterdam retrofitted two antiroll tanks onto GulfMark UK’s Highland Defender and Highland Guardian, both platform supply vessels. In all, 150 tonnes of steel was used for the job.

Niron Staal manufactured the antiroll tank and hull sections, while the shipyard handled the installation at its 250-meter Panamax drydock. Antiroll tanks are installed onto ships in order to reduce the roll motion and roll angle during adverse weather conditions.

“The contract was completed within a six week lead-time only, from the initial steel cutting to the vessels’ delivery,” Flip van der Waal, managing director of Shipdock Amsterdam said in a statement. “The lead-in time was practically zero.”

Prefabrication took three weeks, including constructing the two 75-tonne sections and painting them. Overall, the 87-meter-long PSVs were out of service for six weeks.
