Debmarine Namibia launches next-generation crawler technology

Debmarine Namibia has announced a major advancement in marine diamond recovery with the unveiling of its Next Generation Crawlers, representing a significant leap in offshore recovery technology

This milestone coincides with the delivery of two 800NB crawlers (NB indicates Nominal Bore, the internal diameter of the crawler’s pipeline system) and an upgraded recovery system designed for seamless integration with the MV Benguela Gem.

These advanced crawlers showcase the forefront of marine engineering. Built to operate efficiently in coarser gravels and higher-density panels, they deliver a 20% boost in mining rates and extend pump life by 30%. Each crawler weighs 370 tonnes, redefining operational resilience and capability at sea.

The official unveiling and integration of the new generation crawler onto the MV Benguela Gem took place on 8 September, at Cape Town harbour.

Following the retirement of the MV Grand Banks and MV Coral Sea, the new crawlers are expected to boost Benguela Gem carat recovery by approximately 80,000 high-value carats annually. This increase is projected to more than offset the carats lost due to the retired vessels and aligns with the company’s strategic realignment to address reduced natural diamond demand.

Kevin Smith, chairman of the Debmarine Namibia Board, said, “We are confident that the new crawler investment combined with technological innovation and disciplined cost management, will position Debmarine Namibia to weather the downturn; and will put the company in a better position, poised for recovery when the natural diamond market demand strengthens.”

As the MV Benguela Gem readies for return to Namibian waters at the end of September 2025, Debmarine Namibia acknowledges the exceptional dedication and precision behind this achievement, particularly during financially challenging times. Training initiatives are underway to ensure safe and effective operation of the new systems, reinforcing the company’s commitment to capability development and shared value.

Shakwa Nyambe, board deputy chairperson, said, “This project is a clear example of how strategic foresight and technical excellence come together to deliver long-term value. The new crawlers are not just an upgrade, they are a platform for future innovation.”

“This milestone reflects the ingenuity, collaboration, and pioneering spirit that define Debmarine Namibia,” Smith added. “It demonstrates our unwavering commitment to innovation and excellence in marine diamond recovery.”
