interact with the tanker's ballast system to control the loading
operation. The tanks must be filled in a certain sequence;
otherwise the tanker's structure might be damaged due to uneven
stresses. It is the responsibility of the tanker's ballast system to
signal data to the loading system and to operate the different
valves and monitor the tanks on board the ship.

Pipeline terminal
The gas pipeline is fed from the High Pressure
compressors. Oil pipelines are driven by separate booster pumps.
For longer pipelines, intermediate compressor stations or pump
stations will be required due to distance or crossing of mountain
ranges.
The pipeline terminal includes termination systems for the
pipeline. At least a pig launcher and receiver will be included, to
allow insertion of a pipeline pigging device that is used to clean or
inspect the pipeline on the inside. This is essentially a large
chamber that can be pressurized and purged to insert and remove
the pig or scraper without depressurizing the pipeline. The pig is
often driven by pipeline flow.
