The objects of this transportation are 6 large offshore structural platforms - oil field wharf modules with a total weight of 6000 tons, with a maximum weight of 1400 tons per piece. Our company collaborates with Xiamen COSCO Shipping Logistics: Our company has deployed equipment with 74 axes and 6 PPUs, responsible for the land translation and roll on/roll off loading of this module; Xiamen COSCO Shipping Logistics dispatched four ships, including the "Yuanjian" vessel, to be responsible for the sea transportation business of some voyages of the project. The tacit cooperation between both parties ensured the quality and efficiency of the project's operations. This is the first large-scale offshore bridge transportation in China, with dense batches, short time, and high difficulty. The smooth progress of the project fully demonstrates the professionalism of our operation and technical team.
