Tech Diving Expedition: TDI Trimix Course on HMS Repulse

HMS Repulse Liveaboard technical diving trip provides perfect conditions for helium mixed gas diving.

South China Sea, Singapore

Continuing the expedition James Foleher and James Thornton-Allan departed Phuket and flew to Singapore to join a technical diving liveaboard on the Mv Samudera Quest which departs for 2 days and 3 nights on the HMS Repulse Shipwreck located off the coast of Singapore in south east Asia.

The purpose of this trip is to expose Mr. Foleher to the challenging conditions of the south china sea with strong currents and large swells. In addition to the environment the HMS Repulse is one of the top technical diving wrecks in the world and a perfect destination to combine with the training for the TDI Trimix Diver Course

The divers departed in the morning of the 21st of May and flew Air Asia direct from Phuket to Singapore Changi airport. Buy excess luggage upon booking was essential to avoid the heavy fines incurred from last months flight.

The plan was to meet the divers at Taneh Merrah Ferry Terminal where we would clear customs and immigration and board the Mv Samudera Quest which would start it’s overnight journey out to the HMS Repulse.

The Mv Samudera is a converted river ferry which has been adopted for technical and recreational diving with on board trimix, nitrox, oxygen supply and decompression bar below. The food is excellent and that always makes a difference on every long journey.

Arriving in the morning of the 22nd we were tied onto the torpedo damage section midships of the wreck at a depth of 40m. The sand would be a 55m which would be the majority of our dives since the wreck is almost inverted which meant having to go under the deck to explore the exterior.

During the first dive a British flag was placed on the bow, more to that story found later.

After completing 2 normoxic trimix dives the weather changed and a storm moved in. Unable to remain on site the vessel moved to a local island to seek refuge from the stormy weather. The waves were so strong that it broke the tie off line casting the liveaboard into the waves. Although it proved no concern to the dives it did mean someone would have to go back in and tie the rope back on to the wreck and there were no eager volunteers.

The following day it was decided to move on from the repulse and conducted more dives on the Au Tanker which is a very large and deep tanker with the sand at about 65m. This old vessel appeared to be an insurance scam as it was picked clean of everything that you would associate with a wreck.

Moving closer to Singapore a final wreck called the “Sara-D” wreck is another large freighter which many believed to be larger than the HMS Repulse. This wreck proved to be one of the favorites with large penetrations, crystal clear water and easy access with the wreck lying on it’s starboard side with the hull sheltering the divers from the current.

Singapore has one of the largest commercial shipping ports in the world which provides a lot of wrecks.

Upon returning to Singapore we disembarked and explored the city waiting for a return flight home to Phuket to continue our expedition to Krabi. Congratulations to James Foleher who completed his TDI Trimix Diver Course.
