Utilizing their vast experience in China, Seabridge Contractors Ltd offers clients a program to deliver turn-key, high quality newbuild barges, vessels and steel structures built to the best international standards and design.

Classification may be by Lloyd’s, American Bureau of Shipping, Det Norske Veritas, Bureau Veritas, Nippon Kaiji, Kyokai, or other internationally recognized major Societies.


The key benefits of this proven turn-key program are quality control and integration of a full service package covering financial, technical and supervisory requirements, plus delivery to the buyer’s desired location in the World all without exposing our clients to the risk of running an operation outside of their area of expertise.
