Communication between the terminal and the tanker is a vital link and special care has been taken to ensure complete and continued communications. Communications will utilize a sophisticated radio transmission system. There will always be two methods of communicating with the vessel. In addition, the terminal will be equipped with two visual and audio signals which can be activated from various stations throughout the terminal and on board the tanker. The first signal will be a fire signal. If a fire is present in the terminal, aboard the tanker or the surrounding area the signal can be activated. This signal will consist of a flashing light and a distinctive audio sound. When this signal is activated all operations in the terminal and aboard the tanker will stop. The second emergency shutdown signal will operate in similar fashion to the fire signal but will have a different characteristic light and audio signal and will signal the pumping from the tanker must stop immediately.

Tools to monitor and assess the operations will be available to the terminal operator. These tools are as follows:

1. Meteorological data from a meteorological station at the terminal. This station will report wind speed and direction and barometric pressure. Not only can the operator monitor this information when the tanker is moored at the terminal but the information will be available to the pilots when maneuvering the tanker to and from the dock
2. Bathymetric data from instruments to measure currents and wave height- The wave height information will indicate when low and high energy waves are being built up. These waves may cause the tanker to move around its moorings and put undo tension on the mooring lines.
3. Vessel movement from all degrees of freedom will be monitored from a unique set of GPS transmitters. The transmitter will send a signal to a display in the control room. The operator can then determine the tanker's level of movement. If the indicated movement begins to reach the preset action parameters, the operator can take the proper action.
4. Each mooring hook will have a strain gauge monitor incorporated into it. The strain gauge will measure the amount of strain each line is placing on the mooring hook. This information will be transmitted to the control room. The operator can monitor the information and when the strain on any mooring line or group of lines approaches the preset parameters, the operator can take action.
5. The transfer cargo arms will also have a monitoring system to indicate the position of the arms at all times. Transfer arms have an operating envelop to which they must remain within or damage will be cause to them. These monitors will indicate the exact position of the arms. The operator can take action if the movement of the transfer arms reaches or approaches the operating limits of the transfer arms.
6. Each receiving tank will be capable of automatic measurement. On a fixed pre.established schedule the terminal operator and tanker officers will compare amounts of cargo transferred. It there are significant differences the operation will be stopped until reconciliation can be determined.
7. The marine terminal will be equipped with seismic sensors to provide terminal personel with seismic information.
8. The terminal will be equipped with video cameras for both security and observation of operating conditions. If abnormal activities are observed the terminal operator can take appropriate action.
9. There will be a terminal employee stationed on the pier. This individual will have a direct communication link to the terminal operator. If an unsafe condition arises this person can order immediate stoppage of the transfer process.
10. A laser docking system will be installed to provide the pilot with mooring information.

The information provided by the tools will be transmitted to the control room and integrated into a system from which the terminal operators can monitor the critical information to maintain a safe tanker mooring and loading operation. In addition, each monitoring point will have predetermined parameters established and alarmed to provide the operator with critical information for the operator to take one of the four actions listed above.
