A 55 m accommodation/dive
support barge and attendant tug were mobilised from Singapore
to carry out the excavation. Both Superlite and hooka surface
supplied diving systems were used, with in-water decompression
on oxygen. A decompression chamber was available for emergency
treatment. Airlifts were deployed for excavation, and air tuggers
and an A-frame were used to lift the cargo to the surface.
