7.1 General

All operation at PTT Tank Jetty will be carried out fully in accord with the recommendations contained in the latest edition of the International Safety Guide for Oil Tankers and Terminals (ISGOTT).

7.2 Gangways, Hoses / Loading Arms Connections & Disconnections

Gangways, hoses and loading arms are vulnerable to damage when ships range along the berth. To prevent accidents of such nature, moorings should be adjusted throughout the ship.s stay alongside.

Gangways shall be provided by the Terminal. Ship.s gangway may be required in the event the terminal.s gangway is not available. It must be fitted with handrails and a safety net must be rigged below around the gangway.

On completion of mooring alongside PTT Tank Jetty, the ship will be presented with arms/hoses for loading and/or discharge. It is the responsibility of the shore to ensure that the hoses are maneuvered and connected safely and are correctly rigged, but the manual assistance of the ship.s crew is requested to achieve this. Similarly, on completion of cargo operations, terminal personnel are responsible for ensuring the safe connection and maneuvering of the cargo arms/hoses and ship.s personnel is requested to manually assist with the process, including bolting in place the cargo hose and blanks.

7.3 Cargo Handling Facilities

During the pre-transfer conference, all terminal lines involve in the cargo transfer operation is to be listed down in the „Ship/Shore information Agreement.. Similarly, the ship has to provide the same information such as ship manifold for each cargo to be handled in the „Ship/Shore information Agreement..

7.4 Cargo Transfer Rate

Pumping rate will be established for starting transfer and will take into account the need for precautions when handling cargoes which defined as static accumulators, if applicable, procedures for the final topping off shore tanks will also be established and agreed.

The maximum initial pumping rate for all cargoes shall not exceed flow rate of 1 meter/second as specified in the table below. During the entire cargo transfer operations whether discharging or loading, the pumping rate shall not exceed flow rate of 7 meter/second.

When discharge/loading rate meets above criteria, the maximum pumping rate shall be maintained for the entire transfer operations, and this has to be agreed during the pre- transfer conference.

7.5 Checks on Quantities Transferred

Unless otherwise agreed during pre-transfer conference, ships should provide the Terminal with information regarding the amount of cargo that has been loaded and/or discharged on hourly basis. The terminal will provide the ship with comparable shore figures.

If the exchange of information reveals a sudden or significant difference between the terminal and the ship.s figures on quantities transferred, operations will be stopped until a satisfactory explanation can be found.

7.6 Environmental Criteria for Suspending Operations

Irrespective of measured wind speed, if either the ship.s Master or the Terminal Loading Master considers that the prevailing conditions potentially threaten the safety of operation, transfer should be suspended and arms and/or hoses disconnected.

7.7 Delivery/Handling of Ship’s Store

This operation is strictly not allowed in PTT Tank Terminal.

7.8 Tugs, Boats and Craft Alongside

Except in an emergency or when ordered to assist in mooring, unmooring or maintaining the ship alongside, tug are forbidden to lie alongside any tanker berthed at PTT Tank. Throughout the period when a tug is alongside, all cargo lids, ullage ports and other tank opening must be securely closed.

7.9 Garbage Reception Facilities

This facility not available in PTT Tank Terminal.

7.10 Bunkering

This operation is not allowed in PTT Tank Jetty except in special circumstance that an agreement between the Ship.s Duty Officer and Terminal Representative has been established.

If it is allowed, the receiving tanker must stop all cargo or ballasting operation and batten down during the entire bunker transfer.

7.11 Ballasting

Ballasting is a dangerous operation when gas is being expelled from the cargo tank. All items of the ship/shore safety checklist apply until ballasting and cargo operation are completed and the cargo tanks are finally battened down.

7.12 Deballasting

PTT Tank Terminal does not have ballast facility to receive ballast water from the ship.

De-ballasting may be permitted at all times provided the ballast water is clean and free of oil. It must be clearly understood that the responsibility for avoiding oil pollution rests with the ship. Even segregated ballasted needs to be visually inspected prior de-ballasting.

7.13 Potable Water

Potable water is available for ship supply.
