The dredger, designed for dredging at depths to 14m and producing 4,000 m3/hr, had been built in 2006 for a customer in the Middle East. When the job was completed in that region the dredger was sold to Lagos Channel Management in Nigeria. After the transfer of the dredger, it was undergoing a final inspection and maintenance activities in the Port Harcourt yard when the accident occurred.

Due to unknown causes, the harbour crane fell over and landed on the dredger, completely crushing the wheelhouse. The dredge delivery piping and mufflers were also hit. As the dredger is constructed in heavy steel plate (well above class requirements), the structural components of the dredger were not damaged. Replacement items were ordered to get the dredger back to work as soon as possible.

Damen has improved the design of the wheelhouse over the past year, with a spacious cabin accommodating three crew and isolating them from noise and heat. The cabin is fitted out with air conditioning and double tinted glass and the windows have been enlarged to ensure an excellent view of the deck equipment. Ergonomically designed desks include all controls, ample workspace and an FM radio. With the improved design fitting the old footprint, the cabin will be bolted directly onto the existing foundation. All electrics are fitted out with plugs to enable a smooth installation.

The new cabin was shipped to Nigeria and was due to arrive at the end of May. It should be back at work by now, all within a few months of the accident.
