TRAV&L Bunker Transfer System (TRAV&L Bunker) provides an effi cient and safe method of transferring LNG within the specifi ed delivery envelope. It is based on the principles of hydraulically articulated marine crane technology. A single system controls and deploys two transfer lines capable of handling the transfer of Liquid and Vapour return lines. It offers full control in case of Emergency Shutdown by activation of the powered Emergency Release Couplings.

APPLICATION AREAS:

Bunkering: Ship to Ship and Shore to Ship

Designed in compliance with all relevant standards, codes and regulations, the TRAV&L Bunker is ideally suited for the marine environment onboard vessels or onshore at a bunkering facility where highly reliable safety equipment is required.

Whether the transfer operation is Ship to Ship [STS] or Shore to Ship, the TRAV&L Bunker offers enhanced control over the operation.

The TRAV&L Bunker system provides ESD functionality during the operation by providing the ability to stop the transfer and disconnect both transfer lines in a safe and controlled way if an ESD event occurs.

The TRAV&L protects the hose from being stretched beyond its maximum length or into unacceptable curvatures. Safety lines initiate the following signals.

• Warning • ESD1 • ESD2

HYDRAULIC POWER UNIT (HPU):

The HPU provides hydraulic energy for the hydraulic system components used to manoeuvre the booms, motors and miscellaneous accessories, estimated consumption 50 kW.

The HPU consists of a self-contained unit comprising the hydraulic reservoir on which is mounted an electric motor pump system discharging to a pressure manifold block via an inline fi lter.

Mounted on the pressure manifold are the solenoid operated control valves for the associated control functions. The function valves have a manual operation facility to allow manual recovery functions in the event of a controls power supply failure.

Conforming to applicable Exclusion Zone, the unit’s construction enables the HPU to be located in close proximity to the TRAV&L Bunker. Protection from the elements is provided by robust exterior panels.

HYDRAULIC CIRCUIT FEATURES:

+ High and low speed functionality to aid ERS positioning

+ Independent isolating valves are fi tted for each hydraulic cylinder and/ or hydraulic motor

+ Hydraulic locking system for cylinders and motors when the system is shutdown

+ Stainless steel, hydraulic pipelines and fi ttings used throughout

+ Pressure gauges are provided adjacent to the control panel for monitoring both main & ERS system pressures

+ Connection for an optional external hydraulic supply such as an emergency pump

+ Low pressure system circulation pump providing offl ine fi ltration and system pre-heating and/or cooling

A system HPU providing the hydraulic system requirements to operate the TRAV&L Bunker system can be provided by Houlder as a separate costed option.

6. OPERATION SEQUENCE

The following list is a step by step sequence of the typical operations occurring during an LNG transfer

6.1 TRANSFER OPERATIONS

This sequence is provided as a guideline to show the capability of the TRAV&L Bunker system. Final operation guidance shall be developed in accordance with bunker vessel safety procedure and ISO “Guidelines for systems and installations for supply of LNG as fuel to ships” prior to system onboard installation.

+ Connection link hoses between TRAV&L Bunker and vessel gas system to be rigged and confi gured for vapour or liquid transfer in accordance with the receiving vessel manifold arrangement

+ ERSs to be released from stowed position

+ Horizontal distance between QCDC to be adjusted as per receiving vessel manifold arrangement

+ TRAV&L Bunker manoeuvred to its connection position by slewing and raising the articulated booms

(In connection position, the TRAV&L Bunker head is located vertically over the receiving vessel manifold)

+ ERSs lowered to the receiving vessel manifold platform level

+ TRAV&L Bunker is manoeuvred until contact is achieved between the QCDCs and the receiving manifold fl anges

(Operator/s is required on the receiving vessel to ensure that fi nal connection is achieved)

+ QCDCs to be engaged and jack stand legs extended to the deck to secure the connection

+ TRAV&L Bunker control system is now switched to transfer mode with the ERS winch working in tension

+ Transfer operations such as purging, cool-down, draining etc… can now be safely performed as agreed between the vessels

+ QCDCs disengaged now transfer completed

+ ERSs lifted away from receiving vessel manifold platform

+ TRAV&L Bunker manoeuvred back to its stowed position

BUNKER VESSEL WITH ONBOARD TRAV&L SYSTEM DURING BUNKERING OPERATION

SYSTEM FEATURES:

+ The horizontal span between the two ERSs is adjustable before transfer to ensure obtaining accurate alignment with the receiving fl anges.

+ During the transfer operation, the TRAV&L Bunker automatically compensates for the relative movements between the vessels by its winch operating in tension mode and compensating for vessel movements.

+ Change of loads due to the system release are accommodated by the winch operating in tension mode preventing any shock loads transmitted to the TRAV&L Bunker structure.

+ A Guidance Connection System (GCS) can be provided as an option to facilitate connection operations.

6.2 EMERGENCY SHUTDOWN ESD

The TRAV&L Bunker safety system interfaces with the bunker vessel or jetty safety system throughout operation to ensure that in the case of emergency shutdown, the transfer is stopped in a controlled and safe way.

TYPICAL ESD COMMUNICATION SYSTEM LAYOUT

TRAV&L TRIGGERS THE FOLLOWING SIGNALS TO THE VESSEL/JETTY SAFETY SYSTEMS:

+ ESD1 signal (In the event that vessel drifts over the ESD1 limits) + ESD2 signal (In the event that vessel drifts over the ESD2 limits)

TRAV&L RECEIVES FROM THE VESSEL/JETTY SAFETY SYSTEM:

+ ESD1 signal (actions initiation) + ESD2 signal (actions initiation)

TRAV&L ACTIONS FOLLOWING ESD1 AND ESD2 SIGNALS:

+ ERS shutdown by closing double ball valve + ERC release by opening the emergency collar + ERS retrieved by winching up the transfer line away from the receiving vessel

(This is an automatic action following the ERC release) + Audio and visual alarm
