MacGregor Full X,Y & Z Compensated Crane
When delivered from Fjellstrand shipyard, the 74m infield support vessel Siem Moxie will debut a new offshore crane from MacGregor with three-axis motion compensation. The crane, with a swl of 5 t @ 25m outreach, can land equipment on small, high platforms, or ship-to-ship transfers, where there is little margin for error.
“This crane is a first of its kind, not just for MacGregor, but for the offshore industry,” says Frode Grøvan, Director, Sales and Marketing, Advanced Load Handling. To compensate pitch and roll, the crane’s fixed foundation connects to an internal foundation system, supported by a hydraulically actuated two-directional motion compensation system. Active heave compensation provides the third degree of stabilisation. The jib’s luffing and slewing controls remain fully functional. Mr Grøvan: “This makes precise load positioning possible without shutting down the compensation mode or moving the vessel. While a similar operational end result might have been achieved by making use of the crane’s luffing and slewing functions to control the position of the head of the jib, it would have resulted in a more complex solution and it would have been difficult to achieve the required speed of response.”
