Concept - This system is used to call other engineer to ECR when the engineer on working at local needs help or he found the abnormal condition of machinery. 2. Procedure - In ECR the selector switch must be indicated to calling position and push the "CALL" button, then calling signal will be informed to cabin or public room. Then the buzzer of calling box in room sound and the lamp light. - The engineer in cabin room or public room pushes the "ACCEPT" button on calling box to inform the acknowledgement then the buzzer sounding, and lamp lighting are stopped and the accept signal will be informed to ECR by lamp lighting on console. - The engineer in ECR push the "ACCEPT" button, then lamp light will be off. When calling action is finished, the position of selector switch must be positioned to "OFF". 3. Procedure - There is one more function in the system, which is that when the failure of extension alarm system take place, the alarm signal is informed to all room automatically regardless selector switch position. In this case, acknowledgement action is same as manual calling system Patrol Calling System This system is used to patrol engineer in local area in order to announce the machinery alarm or telephone signal and there are three positions. 1. Patrol Position When the engineer in the engine control room left to local area, the selector switch must be indicated to this position, hi this position, machinery alarm and telephone signal occurred in ECR are extended to air horns and strobe lights installed in local area in order to inform the engineer on patrol. 2. Call Position This position is used when other man wants to call the engineer on patrol or on working in local area. 3. Off position the engineer must change the selector switch to this position when he finished the patrol. If not, the lifetime of air horn and strobe light will be reduced due to long time operating till acknowledgement whenever alarm occur. Pressure Indicating System 1.

These can indicate the overload stress on components and thus prevent an unexpected breakdown. Supervision systems help to achieve optimum operation without overloading can also prolong the operating life of components -giving. With each tank fitted with sensors, the operator can should be able to receive real time information such as levels, temperature, pressure, etc. With supervision and control systems, operators remotely control the FSOs substation and supervise the status of the vessel. In the FSO, it is important to control, management, monitor for power distribution system. Supervision and control systems can effectively reduce the possibility of accidents and the loss of finance. Through supervision and control system, the operator does not need to go to the site to check the status of the device. He can monitor and manage the device in the control room. Meanwhile, the tables, historical trends and reports will be generated rapidly and accurately. The system has run in the factory substation of oil refinery. The results are shown that the data is correct, and operation is easy. Full monitoring and alarm facilities are provided both in the machinery space and in the Engine Control Room (ECR). Sufficient facilities are also provided for machinery watch on the Bridge, and a Watch-calling subsystem enables engineers to be automatically called to the ECR when they are on watch-call duty in their quarters. Thus, both the machinery and the ECR may safely be left unmanned, while machinery watch is carried out on the Bridge The main purpose of the system is to give ship's officers all the basic alarms and status information they require to maintain safe and efficient operation of the machinery. The system is designed to meet the classification society's requirements for periodically unmanned engine room operation. The design conforms to all rules and regulations, and all modules are type approved. Cargo Operation and Bridge Watchkeeping Cargo alarms will sound either at the cargo control room or bridge. These alarms will usually be related to the machineries on deck, cargo tank level, ballast tank level and etc. During operations ongoing, the CCR will be manned, therefore alarms of any kind will be accepted and acknowledged. At the bridge, for the watchkeepers during watch, a Bridge Navigational Watch & Alarm System (BNWAS) is fitted as a monitoring and alarm system which notifies other navigational officers or master if the officer on watch (OOW) does not respond. This system is similar to the dead man alarm in the engine room. In FSO function, the bridge will be minimally manned in accordance with Perenco Safe Manning philosophy. Uncontrolled copy.

The hose reel drum is rigidly connected to the slew ring (via the spokes and drive-end hub), which is driven by four pinions. Each pinion is housed by a gearbox which is controlled by a hydraulic motor. The hose reel control system is used to control the hose reel operations for pay-in and pay-out of the hose. The hose reel equipment is controlled via manual operation of the joystick levers. The control console is used to control the movement of the hose reel. The hose reel is driven by 4 hydraulic motors which turn the slew ring. The motors can rotate the drum in the pay-in and pay-out directions, as well as stopping the hose with the disk brake each gearbox has. The movement is controlled by a joystick on the control console, and its speed increases as the joystick is moved further towards the up/down positions. The central position of the joystick is the neutral position where the hose reel has stopped rotating and the hydraulic motor brakes are applied. As the joystick is moved towards the neutral position each motor slows down, the rotation stops once the joystick reaches the central position and the hydraulic brakes are applied. Uncontrolled copy.

In both situations outlined above, the mooring hook in which the ship's mooring hawser has been placed is opened. The "Quick Release System" is used for casting off the ship's mooring lines and this action can be carried out remotely. Remote operation is carried out using a project-related remote control operating panel. Manual operation of the mooring hook always remains possible by using the release lever. The remote-control system can be used to load the mooring lines into the hooks. The mooring hooks are now executed with a hydraulic cylinder “L” and a proximity switch “H,” which indicate the ‘open’ or ‘closed’ position of the hooks. Safe monitoring with Mooring Load Monitoring System (MLMS) The Mooring Load Monitoring System in place enables us to keep a constant watch on the forces on the mooring lines. Immediate actions could be taken with possible slack or overload situations. Load information is displayed in real time, the alarms can be preset on Safe Working Load requirements. The retrieved data can be used to estimate the number of mooring lines required for safe mooring. Uncontrolled copy.
