Integrated mooring technology relies on the offshore installation project of Persian Gulf oil field. Through independent research & development and innovation, the key problems in two aspects, software design and hardware upgrading, are solved. The parametric design of offshore anchoring, mooring design of multi-pontoon and multi-buoy, shape design of mooring cable and the design of special machines and tools for improving operation efficiency are studied. The technology covers the entire installation cycle from the anchor position design to the offshore installation. The technology is applied in more than ten projects, and is safe, reliable and effective, which is of good economic benefits and popularization value.
