Permanent Oil Containment Boom for a Naval Submarine Dockyard

In 2024, Jerryborg supplied and installed a permanent boom system at the Chinese Navy’s regular submarine dock in eastern China. The client chose us as the supplier to provide the boom to prevent oil spills during the refueling and maintenance of the submarines at this location. After a site visit, our team found that the seawater in this area is relatively calm, and there is little tidal movement. After final discussions, we recommended a permanent polyurethane boom with floats and stainless steel ballast chains.

We deployed the permanent boom in a curved shape in the sheltered harbor area near the jetty. The total deployment length is about 800 meters. Anchor points are fixed at intervals so that waves do not dislocate the boom. Since its installation, the boom has remained in a fixed position almost all the time with minimal maintenance. Our booms are also effective in preventing fuel residue when the submarine is at anchor, helping our customers meet safety standards in the marine environment.

This project is a prime example of Jerryborg Marine’s permanent booms being used at military terminals and in sheltered waters. Based on this project, we have summarized the core technical features of permanent booms. Full technical documentation details can be found below.
