5 Contracting strategy

Depending on the worldwide economical situations, different contracting strategies (for the provision of the selected floaters) can be envisaged, as follows:

  • Full out-sourcing known as EPCI contract.

  • Split work packages to be subcontracted, e.g. (1) Engineering & Procurement, (2) Construction and (3) Installation.

  • Owned facilities or Leased & Operate facilities (FPSO)

The merits (& disadvantages) of above contracting strategies are outside the scope of this document.

5.1   EPCI Contractors

The following table summarizes the main contractors of production floating facilities with references in FEED/EPCm (management of EPC contracts), EPC and EPC+I (Installation) contracts:

  • Lease and Operate Contractors (FPSO)


5.2   Main Shipyards

There are two distinct sub-systems (for fabrication) which form an offshore FPU, namely: (1) the topside and (2) the hull. These two distinct sub-systems with the mooring system drive the schedule (planning) of offshore field development (see Section Section 5.3, “Typical Development Schedules”).

Areas with large ship building industries (hulls and topsides) are in South East Asia: mainly in South Korea (3 shipyards) and Singapore (1 shipyard) with new shipyards capabilities being developed in China and Malaysia. South Korea used to be the world's largest shipbuilding nation in terms of tonnage and numbers of vessels built (all market included). Since 2017, China is the largest shipbuilding country (based on completions in gross tonnage), followed by south Korea and Japan.

The following Table presents the main shipyards and topside fabricators gathered by area:

5.3   Typical Development Schedules

The following Tables present typical development schedules for the main FPUs, and for preliminary evaluation at conceptual phase and study. Such schedules will depend greatly on the worldwide economic status and demands for steel, energy, transportation and resources availability.

Figure 5.4 - Typical FPSO Execution Schedule (see notes)


[Note]

Note

FPSO main characteristics provided here after: FPSO newbuilt or conversion at Contractor standards

  • Process Capacity: 100-150 kbopd

  • Topsides Weight: 30 000 tons (Operating)

  • Storage Capacity: 1.5 M barrels

  • Displacement: 300 000 tons

Theses schedules will depend greatly of the EPC contract strategy.

In case of a Basic Engineering followed by a Call for tender and an EPC contract awarded to a yard contractor (South Korea, China), more time is needed for detail engineering and procurement before to start topside fabrication and overall schedule is significantly extended

The following Table presents typical FPSO execution schedule with yard contractor

Note

FPSO main characteristics are provided here after: Newbuilt FPSO by EPC Yard Contractor

5.4   Transportation & installation

5.4.1   General

The global nature of the offshore oil & gas industry calls for heavy maritime transportation & lifting means for moving large equipments such as hulls or topside modules.

The following Sections present an overview of the Transportation Vessels and Heavy Lift Vessels commonly used for the platforms and floaters transportation and installation.

Refer to ( – Offshore Reference Book) for further technical descriptions of the Transportation Vessels and Heavy Lift Vessels.

5.4.2   Transportation Vessels

Such transportation means from one continent to the other (e.g. TLP hull fabricated in Asia with final fitting of process topsides in the Gulf of Mexico) require large deck load, fast loading, transit and offloading capabilities.

A number of transportation vessels are available and can be categorised in two main groups:

  • Semi-submersible vessels

  • Ship shaped vessels plus craneage capabilities

The semi-submersible vessel disposes of sophisticated ballast system to float-on & float-off typical floating hulls, such as semi-submersible rigs, TLP, FPU and SPAR hulls, see following Figures.

Figure 5.9 - Dockwise ‘Vanguard ’ – MOHO NORD FPU Transportation


Figure 5.10 - Dockwise ‘Mighty Servant 1’ – Thunder Horse Semi-Submersible Transportation


For other smaller equipments (e.g. topside manifolds, mooring reels, subsea foundations) it is preferable (economic) to use the ship+craneage capabilities (Figure 5.11, “Jumbo ‘J1800 class’”), especially in remote area where quay facilities are un-sufficient with crane capacities in the 500T-1000T range.

Figure 5.11 - Jumbo ‘J1800 class’


The main Transportation Contractors are:

5.4.3   Heavy Lift Vessels

For offshore deck integration (SPAR) the offshore heavy lift vessels will be required. The main Heavy Lift Contractors are:

The following Figures present some Heavy Lift Vessels:
