Seadraulics (formerly Specialist Offshore Services) required structural, piping & geotechnical engineering design support to deliver the structural “module” component of their SHFM design. The SHFM subsea structure had demanding specifications such as deployment to seabed at (-)4000m, electrical/hydraulic ROV interfaces, 2 x chemical dosing bladders, flooding system & filters, loading arm and pressure testing facilities.
- Structural design in accordance with DNV 2.7-3 / AISC 360-10
- Piping design to ASME B31.3
- Geotechnical design to API RP 2A / DNV-RP-C205
- 3D interchange of CAD files between mechanical and structural models and Inventor / Solidworks for full clash check
Critical file management of the 3D Mechanical models in Inventor and Structural models in Solidworks for weekly integration and clash checking allowed for a seamless design process. Structural design incorporated Chinese steel sections for COOEC fabrication. No clash problems with fabrication as a result of integrated approach to combined 3D module models.
