Set multiple industry records! How strong is the 'giant' at sea? Get the data!
On the early morning of June 10th, on the work vessel 291, the underwater anchor chain successfully docked with the "Sea Anemone One" traction chain, which means that the last of the 12 anchor chains has been "jointed". At 12:00 on the 10th, the last anchor chain of "Sea Anemone No. 1" was locked and fixed, and settled in Liuhua Oilfield in the Pearl River Mouth Basin. Haikui No.1 "is a high-end marine equipment that integrates functions such as crude oil production, storage, and export, setting multiple records in the construction and installation industry of marine oil and gas equipment.
