The Hong Kong Shipping Register passed the 100 million gross tonnage mark at the end of September with a total of 2,449 ships registered.
The Marine Department said today the register is committed to maintaining Hong Kong's high shipping standards.
As a result of the register's quality control system, the Port State Control detention rate of Hong Kong-registered ships remains at a low level.
Ships registered in Hong Kong remain among the top performers in the white list issued by the Tokyo Memorandum of Understanding of Port State Control, and are classified as low-risk ships in the Paris MoU.
Plus, Hong Kong continues to hold the Qualship 21 status of the US Coast Guard.
The register, the fourth largest ship register in the world, will continue to enhance its services and provide shipowners with technical support and advice.
The department added it will continue to improve co-ordination with Mainland authorities to better protect Hong Kong-registered ships when they are in international waters and in foreign ports.
