The world’s heaviest ship heads out for sea trials

The world’s heaviest ship heads out for sea trials

The Pioneering Spirit, a topsides removal/installation vessel, completed her lifting system commissioning last week and set sail on August 6 for a series of sea trials. Her owner, Allseas, says that she will conduct the trials through August, including several removal and installation evolutions in various sea states. Allseas purchased the support frame and jacket of BP’s defunct North West Hutton platform for purposes of the test, a 5,500 tonne structure which the new vessel will lift up and down for its trials. The lifts will test her active motion compensation system, a key component of her ability to pick up the massive platforms without causing impact damage from rolling and heaving motions. After commissioning, she will head north to Repsol’s Yme mobile offshore production unit, which is slated for removal. She will then return to Rotterdam for installation of four additional lifting beams on her pontoons, which are to be used next summer for removing Royal Dutch Shell’s Brent Delta platform.
