Project situation

On June 27, 2019, our company won the bid for this Design-Build General Contracting Project tendered by Xiamen Road & Bridge Group, undertaking the full-process scope of work. The total length of the relocated and reconstructed pipelines is approximately 27 km. The project broke ground on December 3, 2019, and was put into operation on January 31, 2021.
High-pressure Pipelines:
●The rerouted Sinopec product oil pipeline measures 12.186 km in length, with a diameter of 355.6 mm and a design pressure of 10 MPa. Its designed annual transmission capacity for crude oil and product oil is 3.8 million tons.
●The rerouted CNOOC LNG pipeline is 7.3 km long, with a diameter of D406.4 mm and a design pressure of 7.5 MPa.
●The rerouted China Resources natural gas pipeline has a length of 5.7 km, a diameter of DN600 and a design pressure of 4 MPa.
All the above pipelines are laid along the Shenyang-Haikou Expressway and its surrounding areas in accordance with the corresponding design parameters.
Medium-pressure Pipelines:
This part covers the relocation and reconstruction of the Xinglin and Guankou sections, as well as the connection of the Anren Boulevard section. With a diameter of DN300, a design pressure of 0.4 MPa and a total length of approximately 2 km, the original pipelines are decommissioned simultaneously to ensure transmission safety.

Undertake work

Undertake the renovation of the 306.8-km Kanbauk-Myaingalay section, merging the original 7 bare pipeline segments into 5 pipeline replacement sections. Conduct the redesign of all valve chambers and the cathodic protection system along the entire Kanbauk-Myaingalay section. Perform 16 hot tie-in joints with the original pipeline.


The supporting pipeline project of the Phase I Guangdong Eastern Liquefied Natural Gas (LNG) Project adopts an advanced, mature, and reliable computer-based Supervisory Control and Data Acquisition (SCADA) system for data collection, monitoring, control, and management of gas transmission pipeline stations and yards. Station Control Systems (SCS) are installed at Jieyang Initial Station, Huilai Pigging and Offloading Station, Jiedong Offloading Station, Fuyang Offloading Station, Lianhua Terminal Station, Chaoyang Terminal Station, and Puning Terminal Station. Remote Terminal Units (RTU) are deployed at line block valve chambers, Chaonan Pigging Station, and Xilu Pigging Station. A Dispatch and Control Center is to be established in Jieyang Airport Economic Zone (to be determined).
The SCS and RTU systems complete data collection and control functions, and transmit data to the Dispatch and Control Center through the communication system. Among them, the SCS systems of 6 large-scale stations (Huilai Pigging and Offloading Station, Jiedong Offloading Station, Fuyang Offloading Station, Lianhua Terminal Station, Chaoyang Terminal Station, and Puning Terminal Station) include a Basic Process Control System (BPCS) and an independent Safety Instrumented System (SIS), where the SIS is responsible for the safety interlock protection of the gas transmission stations. One set of SIS is installed at Jieyang Initial Station to fulfill its monitoring, control, and safety interlock functions. The Dispatch and Control Center undertakes data processing, monitoring and control, safety protection, and unified dispatch management of all stations and the gas transmission pipeline network.
