What is the purpose of hook up mooring?

Mooring General Arrangement of the Hook-Up ​Lead tugs are used to tow the FPSO to site, while the stern tugs are used to stabilize the FPSO fishtailing during sailing and installation. Installation Vessels used on site to recover the chains and ensure the connection of the chains with the FPSO.

What is FPSO-FSO turret mooring?

FPSO-FSO TURRET MOORING DESIGN & INSTALLATION ​​The FSO conversion is done by modifying tanker in bow or in midship. External turret mooring system are employed by modifying tanker in the bow area. The FSO are mooring by even number of mooring chains i.e 6,8,12 depending on mooring requirements and commercial viability.

How to hook up FPSO to mooring chains?

How to hook up mooring lines to the FPSO?

The following sequence is to be used to hook-up each mooring lines to the FPSO. Retrieve mooring line end using the subsea or pennant buoy (at the line end location). Chain end is recovered and locked onto the installation vessel.

What is a FPSO vessel?

It stands for floating production storage and offloading (FPSO). These vessels are used extensively by the offshore industry and have become one of the primary methods of oil and gas processing and storage.

How to offload oil from FPSO to shuttle tanker?

When a shuttle tanker is chosen to transport the oil, the offloading of oil from FPSO to the shuttle tanker can be carried out by using an offloading buoy. Alternatively, oil can be transferred from the FPSO to the tanker directly through tandem or side-by-side arrangements.

How do you secure a mooring chain?

After laying each mooring chain, the end of it shall be secured with a pennant to it with a surface marker buoy, with the number of the chain marked on the buoy. Another way is to secure a subsea beacon to the end of the chain which can be subsequently interrogated and the connection made to the end of the chain using an ROV.

How many mooring chains are there in an FSO?

The FSO are mooring by even number of mooring chains i.e 6,8,12 depending on mooring requirements and commercial viability. Risers are attached from chain table to PLEM.
