News Release   December 13 2001 Offshore Systems International Awarded $1 Million Order by United States Coast Guard Vancouver, Canada - December 13, 2001 - Offshore Systems International Ltd. (TSE: OSI), a marine electronic navigation company with a strong defense niche, announced today that it has been awarded an order by the United States Coast Guard. The contract value to Offshore Systems is approximately CDN $1.0 million (US $650,000) and delivery is scheduled in 2002. The order is another in a series of orders for ECPINS® (Electronic Chart Precise Integrated Navigation System) systems, charts and services for the U. S. Coast Guard's Juniper class seagoing buoy tender construction program. John Jacobson, President and CEO of Offshore Systems, said: "The U.S. Coast Guard is a long-time user of ECPINS® systems in its buoy tending fleet. This latest order reflects our company's commitment to quality, service and customer satisfaction in highly demanding and critical applications. Offshore's long-term relationship with the U.S. Coast Guard also reflects our company's leadership position in the naval electronic charting field." The U.S. Coast Guard uses Offshore's ECPINS® on its Keeper and Juniper Class Seagoing buoy tending vessels. These vessels are highly specialized and perform very complex missions in waters that are often shallow and rocky. Buoy-tending crews make navigation safer for other ships by positioning the marker buoys that identify hidden hazards and guide other mariners. The ECPINS® on these vessels are customized to support this mission and ensure that navigational aids are precisely positioned. Once the mission parameters are entered, ECPINS® interfaces with over 800 inputs on the ship and actively maintains the vessel's position by feeding data to the ship's dynamic positioning system. Offshore Systems International Ltd. Founded in 1977, Offshore Systems designs, develops and markets the proprietary ECPINS® (Electronic Chart Precise Integrated Navigation System) line of electronic chart navigation systems for ships. ECPINS® helps to reduce the risk of navigation-related incidents by giving bridge crews a precise, real-time display of their position, course and speed, against a background of fixed obstacles and other navigational hazards. Offshore Systems has developed a strong market position in military navigation, and has ECPINS® systems deployed with the United States Coast Guard, the Canadian Navy, the Royal Danish Navy and the United States Navy.
