The project utilized China’s self-developed \"Shenlong 3\" multi-functional modular seabed trenching machine, as well as 3D sonar and shallow-sea profile instruments to monitor the trenching data, ensuring that the shape and depth of the submarine trenches met the required standards. To ensure flawless installation of the project, advanced technical equipment such as flange measuring instruments with precision exceeding industry standards and high-precision underwater positioning systems was also employed, enabling millimeter-level alignment between the key components of the underwater 30-meter single-point mooring system and the submarine pipelines. This approach filled the technical gap in the installation of \"dual-channel single-point mooring systems\". Once the project is operational, it will solve the problem of oil tankers over 100,000 tons in Bangladesh being unable to dock for unloading oil. Sun Bijun, Project Manager in Bangladesh at China National Petroleum Pipeline Bureau Engineering Co., Ltd.: We carried out independent innovative modifications to the trenching machine equipment, achieving a maximum trenching depth of 11.9 meters ； Overcame the underwater millimeter-level docking technology for single-point mooring systems at sea ； For the first time, the innovative \"offshore reaming and pipe pulling technique\" was employed, achieving a 100% success rate for single-pass crossings.
