DEME Offshore’s newest heavy-lift jack-up Apollo has recently completed a one-month conversion project at Damen Shiprepair Dunkerque (DSDu).
This complex contract involved the installation of a moon pool on the main deck. The technical demands combined with the limited time available required highly precise planning together with working around the clock in order to complete on time.
The moonpool installation was a major undertaking that involved creating an opening right through the centre of the vessel, from the main deck down through the engine stores and finally through the hull. To achieve this without compromising the structural integrity of the 87.5-metre Apollo the work was done in a strict sequence based on strength calculations of the ship’s structure so as to manage the weight distribution.
Before the works could begin, the vessel had to be manoeuvred alongside the quay and then jacked up. This allowed the work to be conducted from a pontoon positioned directly beneath the hull.
The Apollo is now in Scotland for a wind farm installation project.
