Skills development is critical to the Company and ensures that our investment in the development of local talent empowers our employees, our communities and fosters economic opportunity for Namibia. It is with this in mind that the Company puts significant emphasis on skills development through a wide range of programmes including; bursaries, technical training, long-term trainee, self-study assistance, leadership development and safety awareness. Annual expenditure on human resource development exceeds N$20m.

Namibianisation is a key initiative that has been driven at the highest level since the migration of the company from South Africa to Namibia in 2002. Since then, the Namibian portion of the workforce has increased from 18% to 80% to date, which is a remarkable achievement, especially in the light of the scarcity of the highly specialised marine diamond mining skills in Namibia.

Our Namibian Captains

Namibianisation of the Debmarine Namibia workforce is a key initiative that is driven at the highest level. Over the past 14 years, a dedicated effort was taken to train and develop Namibian Captains to master our fleet of six (6) vessels. These employees obtained all-round training from various institutions and attained their Master’s Certificate of Competency. We are proud to produce internationally qualified Masters for Namibia.
