The process starts at the oil drilling rig model, industry enabled for passenger transport to and from the rig. It does not actually deliver oil to ships, this is the function of the oil and LNG loading platform.
Large tanker ships are not used close to a drilling rig, the oil is pumped to storage or to an off shore loading platform for transfer to tankers. The platform model may be seen behind the rig.
Passengers can load at the heliport or the ship wharf at the lower level.
A separate heliport is available, it matches the oil rig design and accepts ships and tugboats. The heliports have straight in track and are especially suitable for the new helicopters that are able to lift vertically above the track using the H key.
