Project Overview

To give a sense of scale of the Project, the Treatment Plant is on board the central section of the MV Benguela Gem Vessel which is Debmarine Namibia’s brand-new purpose-built ship that is 177m long and 27m wide.

Project born out of the need to deliver greater safer and sustainable value for the shareholders of Debmarine Namibia and the people of Namibia, which is home to some of the most sought-after diamonds in the world.

Project size and cost:

“The ~US$420 million custom-built vessel will add an additional 500,000 carats of high value diamonds to Debmarine Namibia’s annual production, an increase of around 35 per cent, while creating 160 high-skilled jobs for Namibians.

Debmarine Namibia is a 50/50 joint venture between the Government of the Republic of Namibia and the De Beers Group. The MV Benguela Gem joins the world-class Debmarine Namibia fleet, which responsibly recovers some of the world’s highest quality diamonds.

The MV Benguela Gem was designed in Nor

Project Details
From inception of the project, the project methodology was to reduce the duration of final assembly at K&L berth as well as the duration for the vessel integration. 3C Metal Belmet achieved this by performing prefabrication of all structural members, Plated structures, Platework and pipework items 100% complete, fully corrosion protected, C0 co
During design, trying to limit the FEA model sizes while still taking into account enough of the vessel for vibration design. Iterative process of ships motion design and vibration design, and their impact on one another. Having a steel deck as the foundation and trying to reduce the vibration transfer between plants Size of modules for lifting; quayside locating for correct sequencing Focus 30 being here and having an end date to leave, waiting for the ship to arrive (delays due to covid) and then the lifts needing to be revised to save time Availability of materials (first during plant design) & then for lifting frame CHSs changed last minute and needed super-fast incorporation into the design and mass considerations of this for the lifts because bigger sections were available The continued change in design, material availability, environment resulted in multiple change in approach and plan to ensure the schedule is not affected. With the stringent COVID-19 protocols in place during fabrication and assembly we have 3C Metal Belmet implemented various work shift to ensure the work can continue with minimal interruptions as well as to ensure personnel are working in a safe environment.
Benefits of Steel in this Application

Most modern-day ships are made from steel. This vessel is also made from steel. As a result of this it is logical to make the treatment plant from steel. Another reason is because of the interface with the Vessel deck, the steel structures are welded onto the shelter deck

Modular aspects of steel are beneficial, quayside construction and rigging onto vessel

Speed of erection

Weight considerations-this is particularly important on a Vessel as there is a weight limit determined by the naval architect

Important to note that the structures are designed for many more loading and boundary conditions than land-based mining structures, steel is well suited to this as it is versatile and handles variable loads and temperatures well
