Offshore pipeline is through a closed pipeline to transport large amounts of oil pipeline on the seabed, which is a major part of the offshore oil (gas) field development and production system and currently the fastest, most secure, reliable and economic mode of transport of offshore oil and gas.
Offshore pipeline transmission medium can be divided into undersea oil pipelines, submarine gas pipelines, undersea oil and gas mixed transportation pipelines and undersea aqueduct, from a structural point of view can be divided into double insulation pipes and single pipes.
The advantage of the offshore pipeline continuous conveyor, almost free from the influence of environmental conditions, not forcing the oil fields to cut or stop offshore oil storage facility capacity restrictions or shuttle tanker is not timely pick. The oil high efficiency, tanker capacity. Addition, the short duration of the laying of submarine pipelines quickly put into production, management, and low operating costs.
The disadvantages are: pipeline in the seabed, the majority need to be buried in the seabed soil a certain depth, inspection and maintenance difficulties, some pipe segments in the tidal range or wave breaking zone (especially riser), by the impact of wind and waves, tide, ice, etc. than floats in the sea and the ship may sometimes be hit or anchor damaged.
