Marine Oil Pipeline Project

Marine oil pipeline is based on the seabed to transport oil pipeline engineering.

Marine Oil Pipeline Project

The marine oil pipelines contain undersea oil transportation pipelines, trunk pipeline and supercharger platform pipeline which are connected with competent part.

The role of marine oil pipeline is mainly mined in the offshore oil fields in t the oil pooled, the exports mooring tankers single point mooring or exports to onshore oil depot.

The Features of Marine Oil Pipeline Project

Large Investment Construction

The laying of a medium-caliber marine oil pipelines need a pipeline vessel, ditching machine, tug boats and more than 10 auxiliary equipments of the large professional fleets. Also, you need a supply of raw materials, equipment and fuel vessels. The costs of fleet are an important cost in the marine oil pipeline construction, which is higher than onshore pipeline.

High Quality Construction Requirements

The maintenance is much more difficult than the onshore pipe as well as maintenance costs for the marine oil pipe line. The marine oil pipeline construction is strict with the quality.

Construction Environment

Sea condition is easy to change with the natural environment for instance wind and sea wave. It is difficult to keep a stable construction fleet. In this case, it is often required the oil pipeline construction into the seabed and resumed construction until the storm stopped.

Complex Construction Organization

The marine oil pipeline construction including pipeline prefabricated fleet auxiliary devices, fuel and fresh water supply needs to depend on the shore base. The location and the determination of the direction also rely on the radio navigation. Therefore, the marine oil pipeline construction is complex and difficult.

Tech & Service of Seamless pipe

Seamless pipes are extensively applied for the nuclear device, gas, petrochemical, ship building and boiler industries. Seamless pipes dominates 65% of market share in Chinese boiler industry.

How to make seamless pipe(seamless pipe process)?
Hot Piercing Workshop
Piercing process
The cross roll piercing and pilger rolling process in the size range from approx. 250 to 660 mm outside diameter.
Precision cold drawn steel tube production process
Pipe weld cracks
often follow different mechanisms can be divided into two types of thermal cracking and cold cracking.
How to calculate a steel pipe and tube theoretic weight
Calculate a steel pipe?
Pipe fittings are necessary to join together pipes, or to change the direction of an existing pipe.
Pipe beveling
Pipe beveling is the process where an angle is formed between the edge of the end of a pipe or tube and a plane perpendicular to the surface.
Steel pipe cutting machine
Pipe cutting
Cutting tools have a grinding wheel piece cutting machine (also known as toothless saw), hand saw, cutter and other hand tools.
Packing the steel pipes
There are probably hundreds of different methods for packing a pipe, and most of them have merit, but there are two principles that are vital for any method.
