China-developed deep trenching technology breaks world records

A multi-functional modular seabed trencher created by a Chinese organization has recently finished 100 kilometers of pipelines design in Bangladesh’s 1st maritime pipeline job, location two earth information in directional drilling and deep trenching.

The seabed trencher was self-developed by condition-owned China Petroleum Pipeline Engineering Co (CPP), which is a skilled enterprise specializing in constructing oil and gasoline storage and transportation infrastructure, less than the China Nationwide Petroleum Company.

The set up of the maritime pipeline project in Bangladesh, a single of the crucial projects less than the Belt and Road Initiative, desires to full six directional drillings and attain a buried depth of 11 meters to stay away from the industrial and naval waterways, generating the unprecedented difficulty in the history of earth marine engineering, CPP stated.

In accordance to experiences, the standard depth of trench digging in the offshore market is 1.5 meters to 3 meters under the seabed, and achieving 5 meters is previously a difficult venture for the field.

To offer with technical difficulties, CPP has carried out impartial improvements and upgraded trenching equipment to achieve a greatest digging depth of 11.9 meters, mastered the underwater millimeter-level docking technological know-how of offshore single-position mooring and adopted the first system that ensured a 100 p.c results in one particular-time drilling.

Following the project is set into operation, oil tankers previously mentioned 100,000 DWT that can not dock to unload oil at ports in Bangladesh, CPP said.

As an essential oil and fuel storage and transportation venture in Bangladesh under the Belt and Road Initiative, the job was introduced as Bangladesh is not capable of dealing with huge vessels carrying imported crude and finished oil because of to very low navigability of a essential river channel and constrained facilities at the primary seaport in Chittagong, the Xinhua Information Agency reported.

In December 2016, Bangladesh attained an agreement with CPP for engineering, procurement, design and commissioning for the installation of one issue mooring with 220-kilometer-extended double pipelines, which include constructing a 146-kilometer-extended offshore pipeline and 74-kilometer-lengthy onshore pipeline to carry imported oil from sea to a refinery in Chittagong district.

The venture is envisioned to have an annual unloading ability of 9 million tons.
