Green Sawfish
Green Sawfish is a groundbreaking modular system for
last-phase rermoval of deck frames (MSF) and gravity-based
structures (GBS). Green Sawfish is a surgical, heavy-duty
subsea/in-air sawing machine that employs state-of-the-art
diamond wire cutting technology to dismantle structures of
virtually any weight, design and material.

Safe, cost-effective, and environmentally friendly
Green Sawfish reduces potential risk to operators due to
its remote control function, which can be operated from
a distances of up to 330 feet. This new cutting tool also
reduces environmental impact, since it replaces the use of
explosives in decommissioning operations.
Green Sawíish can perform cuts with maximum dimensions
oÍ up to 16 ft. x 16 ft. and can be operated at depths of
400 feet.
