Underwater cutting charge

The Supracoupex 850 is a rigid underwater cutting charge mainly used for cutting huge vessel chain links.
The charge is positioned directly on the target over the central part of the chain link.
The locking on target is insured by two ratchet straps that can be positioned transversely or longitudinally on the charge. Specific notches have been designed on the device lid to make the straps assembly and immobilization easier.
The charge has been designed to operate up to 30m deep and is capable of cutting 85mm thick mild steel.
