Detailed Description :

Scope of Work

ode provided Project Engineering Services for platforms SPD5 & SPD6 of Phases 4 & 5 of the South Pars development. These services covered the complete detailed design of the facilities including :

• Verification of initial FEED studies (by Tecnomare)
• Front Detail Design (FDE) in London
• Detail Design Engineering in Tehran in part by subcontract to an Iranian Engineering Company.
• A number of additional services including
• Procurement support
• Follow-on Engineering at the fabrication site in Bushehr

Elements covered by these activities are :

• Wellhead/Process Platform.
• Intermediate Bridge Support Platform jacket
• Intermediate Bridge Support Platform deck
• Bridge 1st span
• Bridge 2nd span
• Flare Platform jacket
• Flare Platform deck
• Flare platform stack

Engineering disciplines include –:

• Process
• Fire and Safety and environmental.
• Structural
• Piping.
• Mechanical, including packaged equipment, vessels and handling equipment.
• Electrical.
• Instrumentation and controls.
• Telecommunication.
• HVAC / Architecture.

FEED Verification

Verification of FEED studies was undertaken, to endorse prior works by Tecnomare. Conclusions of the review as well as any proposed changes to the FEED were compiled and documented in the “Endorsement Report of the Project Design Documentation” prior to implementation of the FDE and DE phases.

Front Detail Engineering (FDE)

The FDE activities, executed over a 7 month period, encompass the preparation of engineering documents for the scope of work listed above. This is developed to :

• Issue of AFC (Approved for Construction) documents – for Primary Structures.
• Confirmation of P&IDs including HAZOP studies and issued for Approval.
• Issue of IFC (Issued for Comments) then IFA (Issued For Approval) – for All other disciplines.
• Preparation of datasheets, MTOs and technical input to enable the preparation and issue of enquiry requisitions.
• Technical bid evaluations of all major packages and long lead bulk materials including technical recommendations and issue of PO Requisitions.

During the FDE phase 3D-CAD PDMS software was used to model the structure, main piping systems and equipment to confirm the layout and provide piping MTOs. All critical lines were stress analysed at this time.

Detailed Design Engineering (DDE)

The DDE encompasses the completion of the remaining part of the detailed engineering following FDE. This was carried out in Tehran by a ‘local’ Engineering Company on a subcontract basis under ode supervision.

The supervision included :

• Dedicated Engineering Manager in Iran until completion of DDE.
• Visiting Senior Lead Engineers who have led during the FDE phase.
• Visits by other consultants with specific high-level expertise as deemed necessary to the completion of work.
• The engineering design team moved to the Bushehr site for the final elements of the work.

Procurement Services

Assistance to SADRA for Expediting and Inspection of packaged Equipment and materials that were supplied from Europe. This support included:

• Provision of Expatriate Procurement Specialist Expediters to work in SADRA’s Tehran offices.
• Co-ordination of all European field expediting and inspection activities.
• Field expediting and inspection visits were undertaken by either project engineering staff from London or local in country consultants.

Follow-on Engineering

This included the provision of a team of specialist expatriate engineers based in the fabrication site at Bushehr to ensure the basis of design is implemented during construction and to assist generally in a construction support role.
