Engineering Design

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

The latter was 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 scope broadening. 

We value our skills as engineers very highly and use state of the art software providing world class interaction with classification societies and clients. We have extensive experience in all aspects of design as described below from heavy steel to general ship structures.
