Wreck Diving Day on Koh Tao Island

Technical and recreational divers explore a ocean wreck in Thailand

Koh Tao, Thailand

Big Blue Tech took eager divers out to the “Big Blue Wreck” today off the coast of Koh Tao Island in the gulf of thailand.

The “Big Blue Wreck” is a wooden passenger ferry that went down without casualty in 45m of water in April of 2009 due to rough weather. Big Blue Tech conducted several searches for the wreck and found her in February of 2010. You can read more about the discovery here: Technical divers discover shipwreck off coast of Thailand

Today’s diving trip was organized to train our divemaster interns on deep, wreck and nitrox skills which started the day previously on a coral dive site and progressed to our deep wreck this morning. The course was conducted by Technical Diving Instructor Helen Artal and assisted by Mark Slinn who is helping out at Big Blue Tech this month as the main staff are in Europe.

On arrival at the wreck site, using GPS to located the wreck a “shot line” or weighted line was dropped as a visual aid for Mark who is a Trimix Diver to descend and secure a fixed line on the wreck for the rest of the divers to use. The shot line was dropped directly on the wreck which goes to show the accuracy and professionalism of the team. After mark secured the line the divers descended and enjoyed 2 dives on the wreck.

This wreck is private and only Big Blue Tech have access to it’s location. This is also in response to environmental research being conducted on the site to the effect of deep coral development and sustainability of wooden wrecks in the region. By keeping the site exclusive it allows for tracking of diver impact on the fragile ecosystem.

Big Blue Tech run frequent wreck day trips throughout the year to several different wrecks along the coast of Koh Tao.
