1.0 INTRODUCTION

1.1 PROJECT BACKGROUND

CONTRACTOR has been awarded by CLIENT for Engineering, Procurement, Construction and

Installation of a FPSO to be installed in the *********. field situated in the Deep Water **** license block,

some ****km offshore Ghana, West Africa, where they and their partners take stakes.

The FPSO is being constructed in the **** Shipyard (“Shipyard”) in Singapore in the form of conversion

from a VLCC and will be delivered and installed to the development field.

CONTRACTOR has earlier delivered another FPSO to CLIENT which is installed and in production in the

**** field in the same license block in approximately 30km east to the **** field.

The FPSO mooring system is a deep-water taut mooring system with an external turret and consists of

three (3) mooring leg groups in 120o separation, each of which has three (3) mooring legs with a

separation angle of 3°. A mooring leg comprises a suction pile, a pile chain section, a subsea connector,

a bottom chain section, a lower polyester rope section, an intermediate chain section, an top polyester

rope section and a top chain section with H shaped mooring connector links. Water depth of the field

ranges from approximately 1,100m to 1,600m. The mooring system layout and mooring components

details are found in Exhibit B and Exhibit C.

The installation of the FPSO and its mooring system will be performed in two (2) separate phases. In the

first phase (“Phase 1”), all suction piles will be installed in the seabed and all mooring legs are

assembled, installed to the suction piles, pre-laid on seabed and then wet stored on seafloor till the next

phase. In the second phase (“Phase 2”), when the FPSO is delivered in the field, all the moorings will be

recovered and passed onto the FPSO turret for engagement into chain supports and thereafter tensioning

to a pre-determined mooring tension to ensure the mooring system performance to its design and

specification. The first and second phases are scheduled in the third quarter 2015 and the first quarter

2016 respectively with a certain schedule window notification scheme allowing adjustment of installation

schedule as detailed in Exhibit D.

Subsea well heads, manifolds, pipelines and flexible flowlines including risers will be installed by others.

The presence and installation of the subsea assets may restrict the mooring leg pre-lay or wet-storage

patterns as well as introducing SIMOPS opportunities. SUBCONTRACTOR shall consider such

background factors and plan their work as defined in SUBCONTRACT in such a way that gives the

maximum flexibility in responding to such potential restrictive situations.

condition. SUBCONTRACTOR shall remove such sea-fastening prior to the hook-up operation. In the

interest of safety it is important that this operation is carried out before any mooring leg attachment is

made to the turret, as the design of the fastenings is only to prevent the turret rotating during transit from

the integration yard to the installation site.

CONTRACTOR shall advise SUBCONTRACTOR of the sea-fastening orientation the turret is when

received at site prior to arrival of FPSO. SUBCONTRACTOR may request CONTRACTOR to sea-fasten

the turret in its preferred orientation to suit the installation procedure.

9.7 MOORING LEG HOOK-UP AND TENSIONING (AHT)

Once all the mooring legs are pre-laid and pre-tensioned and the FPSO is ready for hook-up being

positioned by the positioning tugs, the free end of each mooring leg shall be retrieved from seabed and

handed over to FPSO using the pull-in winch and the wire pull-in rope then engaged into the chain

stopper on turret one by one.

Following hang-off of all nine (9) mooring legs on the turret, the top chains shall be tensioned using the

pull-in winch tensioning rope to a specific value as specified by CONTRACTOR measuring the angle of

the chain stoppers in accordance with Installation Guideline. Tensioning shall be performed by pulling in

the mooring chains section by section. Once a certain chain length is pulled into turret, excess chain

length shall be cut using gas cut torch and pull-in line shall be re-rigged up on the top chain for the next

step of tensioning. The process will be repeated a step by step until the mooring chain tension reaches

the specified value.

CONTRACTOR will provide a mooring engineer on board FPSO to instruct SUBCONTRACTOR for

required tensioning length, sequence, etc.

It is to be noted that the tensioning process shall be performed as evenly as possible for all mooring legs

monitoring tension or angle of all mooring legs and hence cannot be pre-determined. Further

CONTRACTOR will need a certain time to analyse mooring leg angle measurements reported along with

the FPSO turret centre position at each step to determine required shortening length of all the mooring

legs in the next step.

SUBCONTRACTOR shall consider the storm safe condition as defined in Installation Guideline and may

release maximum two (2) bow positioning AHT’s once such condition is achieved depending on site

environment and position keeping performance.
