Divesafe International students dive the wreck of HMCS Columbia during both the Occupational SCUBA program and the Surface Supply program.
A project by the artificial reef society of British Columbia, the HMCS Columbia lies upright in approximately 120 feet of water with a 35 degree list to port. We fear that over the years this list is increasing. The ship was a 366 foot long Restigouche – class Destroyer that served from 1959 to 1974.
Our occupational SCUBA students dive the wreck with enriched air nitrox for extended bottom times. The surface supply students have the opportunity to do penetration dives on the ship.
On surface supply, after a reconnaissance dive to seek out the best penetration points, diver one tends diver two’s umbilical at the entry point while diver two penetrates the wreck. The two divers then swap roles and sometimes entry points. When a diver enters this wreck the sediment inside gets disturbed, reducing visibility.
These surface supply dives give the students some great experience with confined space diving, something they will undoubtedly come across when they enter the commercial diving industry.
