OCTF – Oil and Chemical Tanker Cargo Operations

The lines were foam Mains for foam solution or concentrate are provided the lines should have a number of accessible take off (hydrant) points, which should be spaced not more than two or three standard hose lengths apart. The take off (hydrant) points generally consist of a header fitted with two outlets individually valved and fitted with a fire hose connection suitable for the particular type of fire hose coupling in use locally. Isolating valves should be fitted so as to maintain the integrity of the line in the event of fracture. Suitable pipeline drain valves and wash out facilities should be provided. A foam solution pipeline of this type should cater for a design minimum of 115 cubic metres/hour of solution. Foam concentrate can be distributed through a smaller bore pipe system to the tanks supplying the inductors of fixed or mobile foam making appliances. Fixed pipelines for generated (aerated) foam are of limited value owing to pressure losses in the system and lack of projection

Large capacity monitors would normally be on a fixed mounting. Minimum requirements for monitor operations are a jet length of 30 metres and a jet height of 15 metres in still air.
