Shipdock has recently secured four contracts for the upgrading and maintenance of the jack-up vessels GMS Endurance, GMS Endeavour, Seajack Leviathan and Seajack Zaratan. Each of these is equipped with elevating legs of over 100 m in height.
Shipdock has managed to considerably increase its activities in the offshore market since the very first jack-up barge, the Danish-based A2SEA Sea Jack, came into the yard approximately two years ago. The main task then carried out at Shipdock was to lengthen the legs in order to keep the lower cable sheeves out of the mud in elevating mode. Until some months ago, Shipdock expected to be working on one or two jack-ups per year. Because of the rapidly growing wind park construction activities in the nearby North Sea waters, the total for tis year has risen to four. The most important jobs that the new contracts require are:
– manufacture and installation of new crane pedestals
– installation of heavier cranes
– reinforcement of supporting deck structures
– installation of helidecks
– manufacture and installation of winch foundations
– lengthening of legs (on the GMS Endeavour)
– general project mobilisation work
