NEXT GENERATION
A new, advanced subsea diamond recovery crawler has been installed on Debmarine Namibia’s flagship vessel Benguela Gem, which operates off the coast of Namibia. Following nearly four years of development, the crawler is larger than its predecessors, weighing 370 t and measuring 28 m long and 8 m high and wide. With a sweeping mining arm that covers a 21 m arc in 25 seconds, the crawler operates between 100 m and 135 m below surface, drawing a combination of seawater, sand, gravel and diamond-bearing material through an 800-mm-diameter pipeline.
