WAVE WALKER 1, DORDRECHT, HOLLAND [SEACORE FUGRO]
MD Projects – Wave Walker 1 was designed and built as a multi purpose walking jack up barge. The project for us was as near as you can get to a turn key installation. The hull came out of the ship yard in May and was handed over to the crew in November. We had a four man team on the build. As a company on a new build and these type of installations, we bring a lot of design and practical knowledge to the table that the designer can miss when planning and putting it on to paper. The barge was towed to its first job dredging in Brazil, where it has been used to assist drilling and blasting the sea bed.

MD Projects – Preparation of a 260 meter deep air intake shaft, this consisted of bolting steel mesh back to the shaft wall and shotcreteing. We then pulled a 185mm single wire armoured 11,000 volt cable to surface, the cable was then anchored to the shaft wall every 6 metres to prevent any slippage, communication cables were also installed. We then installed the Alimak lift and a top cover with cage. Access into the shaft was gained via crane and man basket.
Installation of an emergency access staircase in a shaft 40 metres deep in a cross tunnel, the shaft was long hole drilled and blasted, we then formed a concrete plinth at the top for us to install the main bridge to access the shaft safely for inspection and shotcreteing. We then installed the platform brackets and cut the platforms to suite the shape of the shaft. Cages and ladders was installed to the platforms to ensure safety, the final stage was to put the bridge in its rightful place and secure.
Large air doors that were intended to be hydraulically operated for trucks to pass through when mucking, the doors was installed in a main air tunnel and were opened and closed when the direction of air needed to be altered when mining was in progress,
