6Sigma, registered in 2012, was the Exclusive Naval Architecture and Engineering Design Office for DCD Marine Cape Town. (NEWS1, NEWS2)

The latter is known worldwide as a trusted name for multimillion-dollar contracts in the oil and gas, ship, and rig repair industries. DCD Marine Cape Town eventually downsized to meet market demand, which led to 6Sigma receiving as it’s trusted partner. Our tasks broadened to project planning and implementation. In particular, we were entrusted with full projects from concept design, class design, class communication and approvals, procurement, contracting of fabrication, quality assurance, blast and paint, transport, and delivery to commissioning and handover.

6Sigma naturally evolved as a main contractor and became a trusted name in consultancy for maintaining and operating major state assets of South Africa. We also have a reputation for designing project-specific maintenance and equipment structures for fleet clients as well as oil and gas majors. Our company portfolio and client list can be provided on request.
