Alongside us was a team of Royal Engineer divers, also using surface supplied diving equipment, who dug three of the four holes for the four legs of the Underwater Lifting Frame (ULF) then installed that on June 16th. After that they helped us with the tunnelling under the hull.
As a diver in the salvage team I remember many hours spent tunnelling under the hull in the dark using a combination of a water jet, to break up the compacted seabed material, and simultaneously a big flexible airlift between my legs to suck away the spoil. We were tunnelling to reach the bolt positions in order to install the backing plates and nuts to the bolts. As we progressed with this the lift wires could be attached between the ring bolts and the ULF above to support the hull. I did many other diving tasks as part of preparing the hull for the final lift and during the final lift but the tunnelling, bolt and backing plate installation and the lift wires from them to the ULF occupied me the most.
My last dive on the Mary Rose was with Christopher Dobbs on the Monday morning of October 11th and we were tasked with checking and inflating the airbags, which acted as a cushion between the underside of the hull and the cradle. Fifteen minutes after I came out of the water the heart-stopping crunch happened.
