Underwater Burning
ISI divers effectively make clean cuts in black water and high current environments. We have strict safety protocols included in our Dive Safety Plan to protect divers from possible underwater explosions due to cutting gas build up.
ISI divers are capable of directing multiple cranes to set rigging for Heavy Lifts while operating in no visibility conditions and contending with harsh river environments. ISI Dive Supervisors coordinate with divers, topside personnel, and crane operators to safely achieve rigging objectives.
ISI divers are familiar with basic Naval Architecture and can effectively survey hull damage and casualty disposition. From these surveys, salvage plans and damage reports are developed.
Penetration and Tunneling
ISI divers regularly cut access holes and penetrate sunken casualties to perform air-lifting, underwater burning and welding. Divers are also experienced in “tunneling” underneath casualties using high pressure water jetting in order to properly place rigging. ISI Dive Supervisors and Salvage Masters closely monitor and coordinate the above operations to ensure the safety of the diver.
Other Services
ISI salvage divers are also capable of the following; underwater welding, search and recovery, patch installment, fuel lightering, hot tapping, and dredging.
