FLNG Docking and Mooring Systems

TRELLEBORG GROUP 8

General Observations

Onshore/near shore docking and mooring FLNG / FSRU applications.

Majority of current projects are floating onshore regasification.

Floating regasification applications more complex from a mooring system integration standpoint.

Many of the mooring scenarios involve a compound mooring arrangement.

The docking and mooring system elements tend to be considered in isolation.

LNGC/FSRU – Shipbuilder focusing on primarily FSRU Ship-to-Ship mooring system hardware.

FSRU/LNG Jetty – Civil EPC focusing on jetty construction.

The total mooring system must be considered in its entirety.

The “system” includes mechanical elements, instrumentation and control & monitoring.

Mooring


A Primer

Structural Element between entities

Jetty to Vessel

Vessel to Vessel

As it is dynamic it requires observation and adjustment

Because there is a designed state

And an operational state

Aim is to achieve the designed state to limit vessel excursion.

Docking


A Primer

Jetty / Berths, designed berthing speeds

Based on structure loading

Fender criteria (PIANC)

Hull Pressures

Ship to Ship berthing speeds have set limits

Once moored during product transfer,

predefined vessel excursion limits apply

Docking systems monitor all those states

Implements a feedback loop for control of the process

Environmental & MetOcean


A Primer

Designs have set MetOcean and Environmental States

Prior to berthing

Sea States Wave, Current, Water Level , Tide Trend

Weather Conditions Wind , Barometric Pressure, Temperature , Humidty

Lightning / Storm

During berthing

Sea States Wave, Current, Water Level , Tide Trend

Weather Conditions Wind , Barometric Pressure, Temperature , Humidty

Lightning / Storm

Purpose is to ensure Operations can be safely carried out within designed conditions and limits.

System Integration


A Primer

All Data - one system

Distribute relevant data to each party in the operations

Correlation of data for reporting and analysis

Logical control and monitoring

One System

Provide a feedback loop for :

Human Control of the process

Expert Vendor

Fully considered system architecture

One clearly defined maintenance and support path

Potential for a fragmented system

Mooring System Integration Challenges

TRELLEBORG GROUP 19

Safe and coordinated emergency release is critical

29-11-2013

Design Considerations

TRELLEBORG GROUP 20

Instrumentation, Control and Monitoring considerations

Who requires monitoring system data?

– Plant operations/Process Oversight – FSRU and ashore

– Terminal operations floating and ashore

– LNGC deck officers

Where will the cargo operations be controlled from?

Safe execution of emergency release – assurance that only the desired

vessel is released during an emergency.

Equipment choices for Hazardous Areas: Zone 1 Zone 2 Explosion proof

(Ex d) or Increased Safety (Ex e)?

Ingress Protection (IP Rating)

29-11-2013

Compliance Requirements

TRELLEBORG GROUP 21

Compliance to Class DNV , ABS , BV , RINA

IMO MSC /1175 (Guidance on Ship Towing & Mooring).

ISO 28460:2010 Petroleum and natural gas industries — Installation and

equipment for liquefied natural gas — Ship-to-shore interface and port

operations.

OCIMF MOORING EQUIPMENT GUIDELINES (2009)

SIGTTO, LNG operations in port areas

SIGTTO, ESD arrangements and linked ship/shore systems for gas carriers

TRELLEBORG GROUP 26

Quick Release Hawser Hooks

Coordination of QRH sizing (SWL) between Jetty and FSRU

OCIMF guidelines versus MCS – Operational based

“recommendations” versus defined maximum structural limits

QRHs on the jetty may also be utilised by the transient LNGC

Semi Permanent nature of FSRU creates special challenges –

mechanical equipment difficult to access for maintenance

The jetty mooring lines may be terminated by chain stoppers on the

FSRU – typically the mooring winch brake is the limiting factor

TRELLEBORG GROUP 28

Considerations for Floating LNG

Operator safety & risk minimization during operation.

High structural integrity, considering possible “damage state” integrity.

Lift capacity, considering dynamic factors.

Slack wire tensioning

HPU power & redundancy options.

Demanding open sea protection needs.

Deck footprint area minimization

Applications

Jetty based SSL to LNGC

hard arms or hoses.

Jetty based to FSRU based Ship to

Shore

Small Scale LNG distribution

New emerging configuration for Jetty /

STS / Tandem configurations

29-11-2013


TRELLEBORG GROUP 32

Mutual Shutdown: Ship-Shore or Ship-Ship

Required to conform to SIGTTO practice for SSL

In an emergency, prompt controlled shutdown must take place to avoid damage and minimise the risk of spillage

The SSL ensures simultaneous mutual ESD of ship/shore or ship/ship plants in the event of an abnormality signalled by either facility.

Telecommunications between facilities: Hot Line & PABX

Passive Data Transfer between facilities includes transfer Mooring Tensions, monitored Met Ocean data

Active Control for QRH Remote Release where the FSRU is the control centre for Emergency Release of STS as well as LNGC Head & Stern lines leading to jetty hooks.
