Nautilus Positive Locking Subsea and ROV Hooks

Subsea lifting operations are critical, since 2012 the award-winning NautilusHooks™, Subsea and ROV range of “positive locking” safety hooks have been setting the benchmark for Safe, secure and reliable subsea lifting operations.

From shallow water diver ops to deep sea ROV construction projects, the proven safety benefits and robust construction of NautilusHooks provides assurance for your subsea operations, reducing risks, enhancing safety and minimizing costly downtime.


Unique Features Eliminate Snagging and Jamming

Optimized for ROV Compatibility

Nautilus Subsea Hooks are optimised for ROV compatibility, to reduce the known risks and hazards associated with subsea lifting operations.

The unique, patented, safety features include a smooth external profile and unobstructed ROV “grab” shank to the fully recessed, and protected, SS locking mechanism with “single point” ROV activation to unlock, open and discharge the hook.

These unique features are specifically designed to enhance ROV compatibility and operational safety while eliminating known equipment “snagging”  and “jamming” hazards associated with external levers, spring latches or trigger arrangements.

Conversely, Nautilus’s patented locking mechanism never comes under load during operation which provides a smooth, simple and easy “jam free” operation every time.

Nautilus 10t and 22t WLL Subsea/ROV models are now available, in either ROV long shank or Subsea eye release versions. Additional 6t and 32t models coming soon.
