SUPERVISION AND CONTROL

Within the tanker trade, the ship/shore interface plays a vital part in operations. It is an area where differing standards and safety cultures may coexist.

There is no major difference between the general operation of a tanker and the operation of any other type of ship. However, in view of the hazardous cargo transported by a tanker, the crew must be trained to be extra vigilant and to consider at all times the potential risk under which the ship, its crew and its cargo are placed.


Close co-operation between ship and shore personnel is essential for the safe handling of a ship transferring cargo in a terminal. If the operation is well prepared and if open channels of communication are maintained between ship and terminal, there is a good chance that the transfer will be carried out smoothly and that any unexpected incident will be tackled promptly before it can develop into something more serious.

With respect to the equipment fitted on jetties, the ship/shore interface covers:-
■ Moorings
■ Fenders
■ Breasting dolphins
■ Hard arms and hoses
■ Ship/shore gangways
■ Emergency shut-down arrangements
■ Ship/shore links, and
■ Fire-fighting equipment capability

Tankers are loaded and discharged at many terminals around the world by a wide variety of ship types and sizes. Operations range from the very large to smaller terminals handling many different products.

The terminal
During the design of a new marine terminal, minimum and maximum ship size is established. Furthermore, the jetty and its equipment are designed accordingly. Farther offshore, the port approaches and river channel are surveyed. Once a terminal is ready for service, the relevant information needed by visiting ships should be advised to the port authority, ship’s agents, pilots and ship owners’ associations.

The ship
Tankers are normally built in such a way that there is maximum compatibility with a range of terminals. Terminal personnel prior to acceptance of any nomination should always confirm compatibility of any particular ship and terminal from a technical viewpoint. Confirmation should include items such as mooring studies, manifold configurations and ESD link (Emergency Shut Down) compatibility.

Communications

Communications should start before the intended voyage and continue until the arrival of the ship alongside: they must also include the period of cargo operations and continue until the ship departs. All communications should be carried out in a common language so that misunderstanding cannot develop. Usually, apart from some coastal trades, this will be English.

Prior to arrival
As a ship approaches a port, direct contact should be established between ship and shore as soon as possible. Modern communications will readily allow the terminal to update the ship on its requirements for the envisaged transfer operation. Additionally, port requirements, berthing arrangements and the facilities available can also be advised. Similarly, the shipmaster may inform the terminal of the cargo arrival temperatures and pressures, stores and bunker requirements and personnel joining or leaving.
For the planning of ship cargo operations, the shipmaster should be advised by the terminal of all port and terminal requirements relevant to tanker.

Alongside the jetty
As for the earlier parts of a ship’s voyage described in the foregoing paragraphs, reliable and effective communications are a necessity once the ship is alongside.

While alongside and transferring cargo, various means of communication need to be agreed. Decisions must be made on the use of portable radios or telephones. These tools usually form the basis of good communications under normal operating conditions. However, emergency means of communication must also be developed and this will normally take the form of an established terminal operating procedure.

In many terminals, the actuation of emergency shut-down (ESD) valves is interlinked between ship and shore. This communication channel requires a suitable system having plugs and sockets fitted on ship and jetty. Both ship and shore need to be properly outfitted. Such methods of communication are recommended so that a controlled emergency shutdown can always be accomplished. This will always ensure that either the ship or shore emergency shutdown valve, whichever is nearest to the operational cargo pump, is closed first.

Discussions prior to cargo transfer
Before the start of any cargo transfer operation, the intended cargo handling procedures must be thoroughly discussed at a meeting held between the responsible personnel from the ship and the terminal.

The purpose of the meeting is primarily to draw up a suitable cargo plan and to check on safety issues. Furthermore, the meeting has the benefit of making both sides familiar with the essential characteristics of ship and shore cargo handling systems. At the meeting, the envisaged operational and safety procedures and requirements should be covered. Finally, any limitations to be observed during the transfer should be noted in writing. Written agreements should include a cargo handling plan (including transfer rates), communication procedures, emergency signals, emergency shutdown procedure and the tank venting system to be used.

The content of the meeting will depend on a wide variety of circumstances but the following broad outline forms the normal basis for such meetings.

(i) The names and roles of terminal and ship personnel who will be responsible for cargo transfer operations should be noted.

(ii) The terminal representative should check that pre-arrival instructions to the ship on cargo, cargo disposition and cargo arrival temperature have been carried out. They also check that all necessary ship equipment inspections and tests have been performed.

(iii) Similarly, the ship’s officers should satisfy themselves that the relevant terminal equipment is satisfactory and that appropriate inspection checks have been carried out.

(iv) The terminal representatives and, where necessary, customs and independent surveyors should be informed of the cargo tank data, such as:-

• Temperatures
• Liquid heel or arrival dip
• Pressures
• Composition of tank vapour,
• Cargo tank quantities and
• Total quantity of cargo on board

(v) The ship and terminal should then discuss and agree in writing the quantity and types of cargo to be loaded or discharged and in what order. The anticipated transfer rates and, for discharge, the receiving tank allocations should also be agreed.

The cargo transfer operation should be planned and confirmed in writing in order to assure full mutual understanding. The items to be addressed should include:-

• The order of loading or discharging
• The total quantities of cargo to be transferred
• The sequence of discharging and receiving tanks
• The intended transfer rates
• The transfer temperatures and pressures to be expected, and
• The use of vapour return line


(vi) To reconfirm earlier pre-charter advice, the previous three cargoes carried by the ship and the relevant dates should be noted in order to identify and assess any possible cargo contamination problems.

(vii) The appropriate Cargo Information Data Sheets should be provided and should be posted in prominent places on board the ship and within the terminal.

Ship/Shore Safety Check List
When a ship is alongside, no cargo operations or inerting should commence until the ship and the terminal have completed the international Ship/Shore Safety Check List and it has been confirmed that such operations can be safely carried out. It is normal practice that this checklist is presented to the ship by the terminal.


Recommendations on the Safe Transport of Dangerous Cargoes and Related Activities in Port Areas were revised by IMO in 1995. They refer to a comprehensive Ship/Shore Safety Check List covering the handling of bulk liquid dangerous substances with a special section for liquefied gases. It also includes guidelines for its completion.

Operational Considerations
Berthing and mooring
Berthing

Port and terminal authorities should establish berthing and unberthing criteria for safe operations, including limiting wind, wave, current and tide conditions. Requirements for the number and size of tugs must also be set.
