【In-depth discussion on modular installation of HaiChuan】Take a look at the modules manufactured by Penglaijutao for the Yamal project
Thread Content
The largest construction contract awarded to Penglaijutao comes from the YAMAL LNG project in Russia. In July 2014, Penglaijutao won the bid for the utility tunnel modules of the YAMAL LNG project, being responsible for the construction of the tunnel modules for three production lines under Package P3 of this project – a total of 33 tunnel modules weighing around 140,000 tons, of which the structural components weigh about 100,000 tons; the heaviest individual module weighs over 7,000 tons. All of these modules have been delivered.
Located in the frigid Arctic region and being one of the largest projects for building natural gas liquefaction and export facilities in the world, the YAMAL project involves a large number of pipeline modules, with many complex and stringent construction requirements. Package P3, which is under the responsibility of Penglaijutao, consists mainly of three identical production line pipeline modules, with a total weight of around 140,000 tons; of this amount, the structural components weigh about 100,000 tons, and the heaviest individual module weighs over 7,000 tons； The pipeline construction involves approximately 15,000 tons of material, and it requires the use of a large number of new welding techniques. Welding materials made of low-temperature carbon steel for large-diameter pipes at -60°C present significant welding challenges, and the dimensional tolerances at the ends of the pipelines require extremely high precision ； Three large cranes are used to lift the top modules

Modules began to be shipped in 2016. What is the red component on the left side of this conduit module?
The maximum weight of a single piece is 7,000 tons; transporting it is also a technical challenge
It is mainly surface transportation, using multiple SMPT transport vehicles; loading and unloading from ships is a key aspect. When designing the modules, it is necessary to take into account the transportation capacity
What are the requirements for maintaining the same height or slope between the ship and the shore?
It is adjusted through ballast water, and tidal levels also need to be taken into account; there are posts discussing this series, so you can search for them
