Seawalker platform heads for Namibia

DRILLING CONTRACTOR Seacore has sold a Seawalker selfcontained, eight-legged walking jack-up platform to mining company Namdeb for use in mining diamonds in the shallow waters along the Namibian coastline.

Namdeb, which is jointly owned by De Beers and the Namibian Government, will use the walking jack-up platform with an on-board processing plant at Oranjemund.

It will trial sampling and mining methods in the surf zones along a 150km stretch of coastline north from the mouth of the Orange River which forms the border between Namibia and South Africa.

Before Seawalker was shipped to southern Africa the innovative platform played a successful role in very rough conditions - similar to those along the Namibian coastline - on the extension to the UK's Royal National Lifeboat station at Sennen Cove, in Cornwall south-west England (GE August 2002).

Seacore used Seawalker in the heavy Atlantic surf as a working platform for drilling and blasting granite to widen and deepen a 120m long channel for launching and recovering the lifeboat. The platform worked in breaking waves up to 2m high and coped with waves up to 5.5m.

lSeacore and Eidesvik Subsea have signed an agreement to jointly provide offshore drilling services to the site investigation and mineral coring industries.

Seacore will provide drilling and testing systems while Eidesvik Subsea will supply drilling vessels and subsea services.
