Subsea Flooding & Hydrotesting Module (SHFM)

Challenge:

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.

Cube Scope:

  • 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

Outcome:

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.
