Class-level design

Class-level design involves the definition of all the major plans required for approval by the nominated Classification Society and Flag State.

By combining every engineering discipline under one roof, we’ve successfully delivered Class-approved designs for vessels from 9m to 220m.

We’ve worked extensively with all the major Classification Societies and offer a profound knowledge of how to achieve full Class approvals as efficiently and effectively as possible. With each Class society subject to its own nuances, we have the insight to engage Class in educated debate at the appropriate points and ensure that designs are unencumbered by heavy, redundant or expensive features. Where designs do not fit within existing regulatory frameworks, we work closely with Class and Flag to agree compliance based on a pragmatic design solution that meets equivalent levels of safety.

By combining this invaluable capability with our experience in pre-contract design, we can offer single-source engineering for development of all naval architecture, structural, mechanical and outfit factors to meet the most demanding rule requirements. Where appropriate, we integrate a high level of production-ready detailing into our Class-level designs, thereby making it possible to progress quickly into production engineering and potentially saving the shipyard valuable time and cost.

Our Classification-level design engineering services include:


From the engineering calculations mentioned above, we produce high-quality Class-level drawing packages and vessel specifications for vessel cost estimation, contract or further detail design development by the shipyard.
