Offshore modules

Project reference: Design of a modular plant for storage and treatment of drilling mud, compliant with DNV OS-E101 and 2.7-1/2.7-3 requirements.

Our portfolio includes modules and mechanical packages for the offshore oil and gas industry as well as the offshore wind energy sector. We design and engineer a variety of modules and topside structures for fixed production platforms including process modules, subsea templates, living quarters, control rooms and other engineered packages at clients’ request.

We can design and engineer a wide range of offshore modules and mechanical packages, suitable for operation in hazardous areas onboard drilling and production units.
The most significant features of standard designs are as follows:
  • Compliant with North Sea rules and regulations: Norsok D-001 Drilling Facilities and DNV Offshore Standard OS-E101 Drilling Plant.
  • Modules compliant with DNV 2.7-3 as well as OS-E101 during operation.
  • Designed to operate within Zone 1 and 2 hazardous areas.
  • Designed so as to withstand sour service (NACE MR-0175 and ISO 15156).
  • Process piping designed in compliance with ASME B31.3.

What follows is a non-exhaustive list of packages we have developed to date.

  • Drilling mud treatment systems.
  • Cuttings reinjection systems.
  • Chemical injection systems.
  • Methanol injection systems.
  • Riser gas handling systems.
  • Gas scrubbing and inter-cooling systems.
  • Sand handling and treatment systems.
  • Oil, gas and water separation systems.
  • Fuel transfer systems.

Besides developing engineering packages, we can provide technical assistance during the design review process and fabrication. What follows is a non exhaustive list of activities we can undertake to provide support during the fabrication stage.

  • Code consulting, compliance with North Sea rules and regulations.
  • 3D Modelling and 2D drafting, bill of materials, generation of as built drawings.
  • Assistance to material selection, procurement, logistics, customs clearance.
  • Revision of welding procedures and welding maps.
  • Production of traceability records (material certificates, non destructive testing, mechanical tests, etc).
  • Coordination with Certifying Body during design review and production surveys.
  • Engineering and production weight control compliant with ISO 19901-5.
  • Lifting and handling planning.
  • Mechanical testing procedures and witnessing/undertaking.
  • Bolt tightening procedures and verification.
  • Pipe cleaning and flushing procedures and verification.
  • Pressure test procedures and supervision.
  • Coating procedures and specifications, coating production tests.
  • Assistance to mechanical completion, pre-commissioning check lists and commissioning procedures.
