Fossil Energy – Installation
Boskalis’ semi-submersible heavy transport vessel Forte installed the Gallaf GE Central Processing Platform (CPP) topside at its final destination, the Al Shaheen field offshore Qatar, according to the company’s release.
This was done through a DP float-over operation in which Forte positioned the CCP topside between the legs of the pre-installed jacket. By ballasting the vessel, the CCP topside was then mated on the jacket.
A special feature of Forte’s transport and installation project is that the 17,818-ton topside is the heaviest cargo ever loaded on this vessel using the skid-on method.
This involves ‘sliding’ the CPP topside sideways from the quayside onto the vessel’s deck via a rail.
