In October 2003, two successful installations of Transas VTS systems were completed in Namibian ports of Walvis Bay and Luderitz. These VTS projects were implemented in cooperation with Marine Data Systems (South Africa), the contractor and project coordinator. Two independent port surveillance systems fitted by Transas are primarily intended for assistance to Port Control operator to supervise ship traffic within the port area and help ship masters and pilots avoid collisions when following the approaching channel to the ports. The Walvis Bay port has two long approaching channels.
