After a successful walk to work campaign in the summer of 2014, Maersk Oil North Sea UK Limited (MOUK) has again awarded Ampelmann with a contract covering the time charter of their A-Type.
MOUK will use the Ampelmann system for a shutdown campaign in the UK sector of the central North Sea to extend the weather window and increase workability and efficiency. During the Walk to Work campaign (W2W) in 2014, MOUK was able to increase efficiency with approximately 25 per cent compared to the 2013 W2W campaign by using the Ampelmann.
Compensating Heave Motions
This year, the Ampelmann A-type system will be mobilised onto the Island Crown. The system is capable of compensating actual heave motions up to 2.5 metres which ensures safe, efficient and reliable transfers of personnel to the FPSO Global Producer III.
With these so called ship to ship transfers, a seventh DOF compensation is activated. An extra sensor is installed on the target vessel, which transmits motion data to the Ampelmann system in a wireless mode. Due to the received data, the Ampelmann gangway is able to compensate for the target vessel’s motions.
Ampelmann is the only company in the world who succeeded in these ship to ship transfers with a MCG.
