Swire Pacific Offshore says the first example of its new class of icebreaking PSVs, the UT758 Pacific Endeavour, started ice trials on March 13th when it arrived at the edge of the Artic polar pack.
Said Swire: "Prior to departure there was considerable anxiety among the ice experts about finding sufficient first year ice of the quantity and quality required due to the unseasonably warm winter in the extreme northern hemisphere. However, it turned out the polar pack ice was thicker than anticipated from the forecasts, and the vessel was frequently encountering areas of ice of 4-6m thickness capped with 1.5m of snow."
Apart from ice manoeuvring trials the vessel also conducted a full push test to confirm the maximum torque and maximum revs of the motors at 7MW of input power at the Aquamaster thrusters.
"All on board were extremely impressed with the way Pacific Endeavour handled ice that was well over the initial design specifications, and well in excess of what will be found off Sakhalin Island where the vessel will operate," said the company.
The channel widening test was passed with flying colours, achieving a 65m channel through 45cm ice and 10cm snow in excess of 2.5 knots headway, as were subsequent trials.
