Offshore Pipeline is witnessing massive installations with increasing demand for crude oil and gas worldwide

 

Offshore Pipeline

An offshore pipeline system is a buried pipeline that is dug beneath the ocean or in saltwater areas in close proximity to shore. The pipeline is constructed within an underground trench or under the ocean bed to protect the pipeline from the corrosive effects of the salty sea water. In some instances, the pipeline is completely on-land but at other locations it traverses water bodies, including large oceans, small rivers and even small straits. The majority of offshore pipelines are located in the U.S. although there are also many that originate in various foreign countries. For example, the largest onshore pipeline system in the world is the Trans-Alaska Pipeline System, which is located between Canadian and Alaska.

An Offshore pipeline system can be a very useful method of transportation of both crude and natural gas. Offshore oil drilling and petroleum production on land have created many problems for the offshore oil industry. This method of production has caused many environmental issues such as coastal erosion, missing beaches and valuable underwater wildlife such as the salmon. On the other hand, offshore pipeline systems allow for the easier transportation of natural gas and petroleum products from well to well. The transportation methods vary by each natural gas carrier.

An offshore pipeline system can be used in numerous applications. One such application is to transport crude oil from the well to the sea floor. The transport of crude oil is done through the use of an offshore pipeline system which is separated by the use of seams or in other words seabeds. The cost of transporting offshore gas is considerably less than the cost of ocean shipping. Most offshore pipelines are generally located in deep water, offshore areas where it is difficult to install the system. Offshore pipelines generally run between the continental shelf and the continental deep water. Recently, in September 2020, Morrison, a U.S.-based contractor, installed oil and gas pipelines for Byron Energy’s South Marsh Island Blocks in Gulf of Mexico.
