When a moderately large project suddenly more than doubles in volume, flexibility and rapid responses are the order of the day. Strengths that the team demonstrated once again in the course of the repair order for the suction dredger ‘NORDSEE’.
Unexpected order volume
The original repair schedule covered only general task for class renewal of the vessel and a few additional items. These included, amongst other things, steelwork in the hold (hopper compartment) and on one forward ballast water tank, and the replacement of the suction tubes. Shortly after the arrival of the dredger at the shipyard in February 2014, it was discovered that this was going to be far from enough. The repairs needed in the hold and for the ballast water tank turned out to be much more extensive than planned. The following tasks had to be added to the repair schedule:
- Replacement of the greywater and blackwater piping
- Replacement of major components of the heating system
- Repairs to the sweeping arms
- Repairs to the dredging equipment, including the booms, pawls and suction mouth systems
- Gutting and renewal of the deck house fittings
- Replacement of windows and installation of energy-efficient insulation for the deck house
Successful shakedown cruise
After 15 months laid up at the yard, the ‘NORDSEE’ headed for her namesake, the North Sea, for a shakedown cruise. All trials under weigh and tests of dredging operations were passed according to plan. The order was completed on time and the ‘NORDSEE’ returned to her home base in Wilhelmshaven without further delay.
