DASH7 comprehensive subsea structure design services covers conceptual, FEED and detailed engineering and development of subsea structures. We have worked closely with our client throughout the project starting from initial development to fabrication to ensure a fit for purpose design that meets project delivery schedules.   

​Our comprehensive design services are supported by our team of experienced 3D modelling draughtman and subsea structure engineer. At the preliminary stage, 2D or 3D conceptual model is prepared, followed by detailed stress analysis to validate integrity of the subsea structure. Subsequently, design drawings is prepared for fabrication, material take-off and weight take-off. We can provide preliminary drawings and MTO as early as possible to expedite procurement of long lead items.

Our capabilities in subsea structures design in shallow or deep water project include:


  • ​Subsea manifolds / PLEM.

  • SSIV Structure.
