International Maritime Security (IMS) has become the world's leading expert in the provision and implementation of the International Ship and Port Facility Security (ISPS) Code.

Since 1986, IMS has been retained as security consultants by over 500 maritime companies, and in 1996 was commissioned by the International Council of Cruise Lines (ICCL) to prepare the model generic Ship Security Plan (SSP) for all its members.

The US Marine Safety Centre accepted this SSP as meeting in full the provisions of the US Coast Guard Federal Register Regulations.
