Below loading is explained basis my present vessel. See the diagram for better understanding. The cargo oil tanks are divided into three segregations or groups which can be used either individually or combined to permit the loading of the nominated quantities. Group 1 consists of No.1, No.4 COTs and the starboard slop tank Group 2…
System explained basis my present vessel Cargo oil tanks are crude oil washed to comply with both legislation (contingency ballast requirements) and charterer’s requirements in order to achieve maximum out-turn. This would usually be No.4 COT port and starboard (nominated heavy weather ballast tanks) and one quarter of the remainder. However, no tank requires to…
System explained basis my present vessel. The deck mounted tank cleaning machines are turbine driven, fully programmable, single nozzle units. The nozzle performs a helical pattern by rotating in a horizontal plane, combined with a very slow vertical movement. The machine can rotate 360° in the horizontal plane and up to 135° in the vertical…
The Gas Sampling system is a gas detection system which monitors and detects explosive gases in the pump room. The system monitors for hydrocarbon content. Additionally, there are two gas sampling points in the accommodation, one at each entrance door on ‘A’ deck. The gas detection system is an automatic scanning, permanently installed gas detection…
The burner is of the rotary cup type and so does not require any atomising steam or air supply. Control air is needed for valve actuation and purging and an electrical supply is required to operate the rotary cup drive motor. Combustion air is supplied by means of an electrically driven forced draught fan. The…
The Electronic Governor System is a control system designed to accurately maintain the output shaft speed of the main propulsion engine to a given order. The governor consists of a microprocessor unit at the engine revolution control part and a fast response electrical servomotor with reduction gear at the actuator part. The servomotor unit is…
The engine protecting system (EPS) is designed to monitor the ship’s main engine performance and speed, then control the engine protection functions, such as shutdown and slowdown, if the engine’s monitored operations exceed defined limits. The protecting system provides the following control and monitoring facilities: Control of: • Emergency stop • Engine shutdown • Engine…
Introduction The Bridge Maneuvering System is a bridge maneuvering system used for the remote control of the ship’s main diesel engine which is connected to a fixed pitch propeller. The maneuvering system allows for remote engine control from the bridge or engine control room. Control may be transferred between these stations and may also be…
Requirement Following the entry into force of the BWM Convention on 8 September 2017, all ocean-going vessels are required to record each ballast operations in a BWRB. Appendix II of the BWM Convention (Form of ballast Water Record Book) specifies the type of ballast operations that should be recorded, as a minimum, in the BWRB….
High expansion foam provides fire extinguishing capability by excluding oxygen from the seat of the fire and by the cooling effect caused by the evaporation of the foam bubbles. Foam is made by mixing a foam making chemical with sea water. The sea water is supplied from the emergency fire pump. The foam liquid tank…
