News Release   June 20 2002  U. S. Coast Guard Places New Orders with Offshore Systems International Ltd. Vancouver, Canada - June 20, 2002 -- Offshore Systems International Ltd. (TSX: OSI), a marine electronic navigation company with a strong defense niche, announced today that it has received C$2.2 million (US$1.4 million) in new orders from the U. S. Coast Guard. These orders are for additional Offshore proprietary ECPINS-M (Electronic Chart Precise Integrated Navigation System-Military) systems as well as system upgrades. "The order for system upgrades adds ECPINS®' full range of electronic chart data handling to the U.S. Coast Guard's ECPINS-equipped buoy-tending vessels," said John Jacobson, President and CEO of Offshore Systems." The order for new systems completes initial installation of ECPINS® on the Coast Guard's two "Polar-class" icebreakers." The first ECPINS® system for the Polar class was procured and deployed earlier this year. "As the Coast Guard's fleet is significantly expanded to better protect the 360 ports and 95,000 miles of coastline and waterways around the United States, under the proposed budget of the new U.S. Department of Homeland Security, Offshore looks forward to continuing to provide the Coast Guard with the most advanced electronic chart navigation technology," Mr. Jacobson said. Offshore Systems International Ltd. Founded in 1977, Offshore Systems designs, develops and markets the proprietary ECPINS® 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.
