The De Beers marine business unit recently embarked on a project to upgrade the power and propulsion system on their ‘Gariep’ offshore mining vessel.
The project will include modifications to the vessel to facilitate the physical and functional integration of new generating plant and a new electrically driven propulsion system.
Additionally, the project will involve changes to support auxiliary, structural and control systems. JB Switchgear Solutions secured the contract for the low voltage primary switchboard.
The scope includes manufacture, factory acceptance testing, delivery, installation and ‘C1’ commissioning of the switchboard.
This marine-certified, 100kA, 600V, 60Hz switchboard includes 1 x 6300A, 5 x 5000A and 2 x 1600A air circuit breakers. The switchboard is fed from four diesel-powered generator sets and includes synchronizing capabilities.
Strict quality control procedures at JB Switchgear, and adherence to the applicable marine standard for the manufacture and assembly of this switchboard, are in place.
JB Switchgear is a level 3 BEE supplier, and ISO-9001 listed for its quality management system.
