Scope and Application

The mooring system provides position keeping to support the production and operation in the context of Rules and Guides mentioned above, and may be a part of the mandatory classification such as in the FPI Rules, or have a separate optional classification notation requested by the owner. This Guide provides detailed classification requirements for the mooring systems. The Guide is applicable to offshore position mooring systems including, but not limited to:

i) Spread mooring systems

ii) Turret mooring systems (internal turret and external turret)

iii) Catenary anchor leg mooring (CALM) systems

iv) Single anchor leg mooring (SALM) systems

v) Disconnectable mooring systems

vi) Pre-laid mooring systems

vii) Thruster-assisted mooring systems

The Guide does not cover the tendon systems for Tension Leg Platforms (TLP).

The main components of the mooring system include:

i) Mooring line

● Chain, wire rope, synthetic rope, or a combination

● Clump weight

● Spring buoy

● Connecting hardware (shackle, swivel, other connectors)

ii) Winching equipment

● Windlass

● Chain jack

● Drum-type winch

● Linear winch

● Traction winch

● Fairlead and stopper

iii) Anchoring system

● Drag Embedment Anchors

● Pile Anchors (driven, jetted, drilled and grouted)

● Dynamically installed piles

● Suction pile and Suction Caisson

● Gravity Anchor

● Plate Anchor (drag embedded and direct embedded)

● Suction embedded plate anchor (SEPLA)

iv) Where applicable, the mooring system may also include the following

● Turret for turret mooring systems

● Disconnection system for disconnectable mooring systems

● Thrusters and thruster control systems for thruster-assisted mooring systems

iv) Where applicable, the mooring system may also include the following

● Turret for turret mooring systems

● Disconnection system for disconnectable mooring systems

● Thrusters and thruster control systems for thruster-assisted mooring systems
