Subsea structures and pipeline design

Design and design review for subsea structures, offshore pipelines - both in shallow and deep waters - and onshore pipelines aim at supplying a company with a final package of documents that can be used to make a FID (Final Investment Decision) for a project or for the tender phase with EPCI (Engineering, Procurement, Construction and Installation) contractors.

Typical activities are:

• Concept selection amongst the different available technologies
• Cost estimation development
• Preparation of an invitation to tender (ITT)
• Assistance during bidders’ evaluation and selections.

Focus on owner engineering

The services provided range from design input data, premises, assumption, company standards - with the optimization of the general field layout - and pipeline (offshore & onshore) routes, to the completion of the design and the production of a package of documents that enable the company to release the invitation to tender.

Deliverables

• Evaluation of potential alternatives and definition of the best solution for the field
• Development of a cost estimation for the EPCI / installation contractor’s scope of work
• Provision of a turnkey package to be used for tender purposes
• Concept selection studies and routing
• Economical and financial feasibility
• Basic and FEED design
• Detailed design and field engineering
• Advanced design, analysis and simulations
• Geo-hazard.

Special studies:

• Health & safety
• Environment
• O&M
• Pipeline integrity management
• Structural monitoring and leak detection systems.
