News Release   October 21 2002 Offshore Systems International Equipping U.S. Navy Carrier Battle Groups With Electronic Navigation System Vancouver, Canada -- October 21, 2002 -- Offshore Systems International Ltd. (TSX: OSI), a marine electronic navigation company with a strong defense niche, announced today that it received a C$450,000 (US $285,000) order for its proprietary Electronic Chart Precise Integrated Navigation System-Military (ECPINS-M) software to provide an enhanced Navigation Situational Awareness capability for certain undisclosed United States Navy Carrier Battle Groups (CBG) and their associated Amphibious Readiness Groups (ARG). "Offshore Systems is proud to provide the next round of Situational Awareness electronic chart systems for operational deployment. This latest order is a follow-on purchase from the U.S. Navy's roll out of ECPINS-M on the USS George Washington Carrier Battle Group and the USS Nassau Amphibious Ready Group," said John Jacobson, President and CEO of Offshore Systems. The Company is delivering this new software order immediately, and expects the sale to be reflected in Offshore's fourth quarter revenue. A CBG/ARG is a single combat unit consisting of an aircraft carrier, embarked air wing, and eight to ten escort vessels, which are part of the U.S. Navy's Atlantic and Pacific Fleets. In 2001, the United States Navy established an interim goal to provide all deploying ships with a standard electronic charting system for improved situational awareness and to facilitate a cultural transition leading up to fleet-wide implementation. Offshore Systems continues to work closely with the U.S. Navy during this transitional phase as the Navy works toward the fleet-wide implementation of it's ECDIS-N (Electronic Chart Display & Information System-Naval) standard. ECPINS-M is Offshore Systems' electronic chart navigation system for military and government fleets. It handles a wide variety of official chart and specialty data types, and has a number of key functions that support vessel operations in a complex mission-oriented environment. In 2001, Offshore Systems received fleet-wide orders for ECPINS-M from the Canadian Navy and the Royal Danish Navy. 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.
