System as per my present vessel The automatic cargo stripping system is provided to improve the efficiency of stripping the cargo oil tanks and to assist in the maintenance of high bulk rate discharge. It utilises the cargo oil pumps to complete the stripping operation


System described basis my present vessel FULL DISCHARGE The following factors are to be considered prior to a full discharge: •    Maximum available draught at the berth •    Maximum allowable freeboard on the berth •    Grade segregation, if carrying multiple grades •    Crude oil washing


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

Crude Oil Wash

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

Crude Oil Washing System

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 stripping pump is a steam driven, double stroke, reciprocating type pump, controlled  from the cargo console in the CCR. The stripping pump can be used to drain the cargo lines and the pump room bilges to the port or starboard slop tank, to shore


Normally on oil tankers the main cargo pump system consists of three vertical centrifugal single stage double suction type cargo pumps. They are situated at the bottom of the pump room and are driven by a single stage Curtis steam turbine and intermediate shaft passing

Refrigerated Containers

A large variety of cargoes carried in containers today – everything from ice cream to New Zealand lamb, from avocados to flower bulbs, from melons to fish – all require different specialist refrigerated care. Considering the high cost of most reefer cargoes it is important


Containers of various sizes are used in the industry and we shall now understand how they are utilised for cargoes of various sizes and types. Size of containers The standard containers consist of the following size: – Hi-cube containers have the dimensions of 20’/40’x8’00”x9’00”or9’06”. In

Container Vessel – Stowage plan & Slot Identification

On a general cargo vessel the identification of the location of a parcel of cargo was a simple process. Since the vessel was divided into holds, the first parameter was the hold. Each hold was divided into lower hold and tween decks hence the next
