Continuing its long-standing relationship with De Beers Marine (part of the De Beers group of companies), Tenova TAKRAF Africa has delivered a Tenova Dynamic Scrubber for installation on a new deep-water diamond exploration and sampling vessel, the MV SS Nujoma. The vessel will be operated by Debmarine Namibia off the coast of Namibia and the West Coast of South Africa. Debmarine Namibia is a joint venture marine diamond prospecting and mining company owned equally by De Beers and the Government of the Republic of Namibia.
Construction of Tenova Dynamic Scrubber in progress on the quayside, Cape Town, South Africa.
TAKRAF Africa’s scope of work covers design, supply, manufacture and delivery, as well as technical assistance during installation and commissioning on the quayside and at sea (where hot commissioning will take place). De Beers Marine placed the order for supply of the scrubber following successful completion of the initial design study phase awarded to ADP Consulting. The 4.5 m3/sec scrubber was ordered in November 2015 and will be installed by ADP Consulting on the sampling vessel, which is under construction at the South African port of Cape Town.
As a wet dust extraction system, the Tenova Dynamic Scrubber will collect dust extracted from the air in a slurry, before discharging it into on board sumps that utilize seawater. The air vented to the atmosphere will contain less than 30 mg/Nm2, well within environmental regulations. In the diamond-processing industry, wet dust-collection systems are the preferred means of achieving low dust emission levels to protect both operators and machinery.
The highly specialized and technologically advanced MV SS Nujoma will become the sixth ship in the Debmarine Namibia fleet and will be registered at the Port of Lüderitz in Namibia. It is named after Namibia’s founding president, Dr. Sam Nujoma.
Previously known as Bateman Engineered Technologies (BET) prior to the acquisition of the Bateman Group by Tenova in 2012, TAKRAF Africa supplied dynamic scrubbers as well as other equipment for most of De Beers Marine’s sea mining vessels. These include the deep-sea mining vessels, the MV Debmar Pacific, the MV Debmar Atlantic and MV Peace in Africa.
TAKRAF Africa has an extensive reference list of more than 3,000 dust control systems installed in Southern Africa over the past 50 plus years. Tenova Dynamic Scrubbers are simple to operate and enable low dust emissions to be achieved with relatively low capital and operational costs. The scrubbers are used for general dust collection of medium to heavy dust loads with an efficiency of 99 % for particles in the 1 to 2 micron range. The smallest dynamic scrubber can handle 0.2 m3/s, while twin arrangements of the largest scrubber handle up to 65 m3/s.
“We highly value such repeat orders as they are testimony to both the superior performance of TAKRAF Africa’s technology as well as to our commitment to supporting our products over their complete lifecycles,” says Jimmy Tomlin, Manager: Air Environmental Control, TAKRAF Africa. “We are proud to have been associated with De Beers Marine since the 1990s.”
