Abstract: In this research project, a Tanker Loading and Simple offshore Fire-Water Ring-Main systems were studied using the Sunrise Pipe-net Application and three cases which comprehensively cover the cases that normally occur in Loading and Fire-Water Systems were considered.
Tanker Loading and Fire-Water Ring-Main systems are usually located near the sea and in most cases offshore and therefore, are often susceptible to suffer from pressure surge problems; hence considerable care must be taken in their design. Subsequently, if there is a leak of hydrocarbon material, it could lead to a potential environmental disaster, such as fire and oil/gas pollution.
Tanker loading systems normally has two valves which could be the source of problems in the operation of the system. The Normal Shut-Off Valve (NSV), which operates on a daily basis as tankers need to be loaded or unloaded and the Emergency Relief Coupling (ERC) valve which is also of interest and operates when the system needs to be shut down in an emergency, such as storm or leakage. This valve which is usually located at the end of the jetty is designed to shut quickly and disconnect the hose going to the ship in an emergency situation.
Consequently, both closure of the NSV and ERC valve were considered for these design purposes. The operation of the NSV was considered because it operates on a daily basis. Even if the maximum pressure is acceptable, it could progressively weaken the connection and the system could start leaking. In anticipation of a loading system failure, there was need to design a Fire protection system on onshore/offshore platforms and process plant, since hydrocarbon materials are highly flammable.
In the end of the project, surge analyses were carried out based on the requisite force calculations and graphical results were generated to analyse the system design.
