Dalian COSCO Shipping Heavy Industry Completed the Maintenance Project of the "China Oil Sea 5" Platform and Set Sail Smoothly

A few days ago, the jack-up offshore drilling platform "petrochina Sea 5" completed all the repair projects in Dalian COSCO Shipping Heavy Industry, successfully towed the factory, and went to the Bohai oil field for drilling operations.

"CNPC Hai5" is a drilling platform belonging to CNPC Offshore Engineering Drilling Company, with a total length of 75 meters and a height of 72 meters. Because the platform has an established lease before entering the factory, China Oil Sea hopes Dalian COsco Shipping Heavy Industry to shorten the construction period as much as possible under the premise of ensuring safe construction.

Combined with the problems encountered in the project planning and the needs of the owner, the project team made a lot of communication with the owner's maintenance before the start of the project, and formulated the construction plan based on the drawings. In the maintenance project of the platform, the project team innovatively adopted the method of semi-submersible barge docking platform for maintenance, avoiding the additional occupation of ship repair wharf and dock caused by drilling platform station piles, effectively releasing the company's ship repair resources, and opening up a new mode of offshore platform maintenance of the company.

In the process of promoting the project, the workshops promote the relevant work in a reasonable and orderly manner according to the planning, and the green and environmental protection rust removal process is adopted in the painting construction of the project. High pressure water knife is used to remove rust on the pile legs and robot is used to remove rust on the hull, which not only ensures the efficient promotion of construction, but also its environmental evaluation is highly recognized by the shipowner. In terms of the transformation and dredging of the pile leg spray system, the project team wanted to what the owner wanted, and urgently needed the owner. After repeated tests and explorations, the project team finally found the simplest and most economical method to solve the problems that had plagued the ship for more than ten years, and was highly praised by the owner.

Finally, the "China Oil Sea 5" drilling platform successfully completed various repair works and went to the offshore oil field operation area. After sailing, the ship owner sent a letter of thanks to express his affirmation and praise for the company's project team, and said that the follow-up will continue to cooperate with Dalian COSCO Shipping Heavy Industry on offshore platform maintenance business.
