DASH7 comprehensive subsea structure design services cover 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 draughtsmen and subsea structure engineers. At the preliminary stage, a 2D or 3D conceptual model is prepared, followed by a detailed stress analysis to validate the integrity of the subsea structure. Subsequently, design drawings are prepared for fabrication, material take-off and weight take-off. We can provide preliminary drawings and MTO as early as possible to expedite the procurement of long-lead items.

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


  • ​Subsea manifolds / PLEM.

  • SSIV Structure.

  • Riser base;

  • PLET and in-line wye/tee assembly.
