“Vancouver, B.C., based Vard Marine, Inc. reports that the Canadian Coast Guard has awarded it an engineering services contract to explore concepts for the Coast Guard’s future fleet renewal program.
“…The work is intended to explore requirements for multiple future fleet ship types and could stretch over several years.“
Vard was of course a designer of the Offshore Patrol Cutter.
