Subsea Lifting Anchors for ROV Installation (Patented)

These are designed to save ROV operation time and are vailable in several sizes with a capacity of 10, 13.5 and 30Te and with angle deviation up to 90ºfrom the direction of the drilled hole.

Subsea Worm Gear

Subsea worm gear are for use in ROV tooling applications where a compact, oil filled and compensated transmission unit is needed. They are available in three main sizes with numerous alternative ratios, output torque from 100Nm to 1500Nm.

Subsea Winch 50 kN

This is a compact winch that focuses on optimization of the weight/performance ratio to carry out demanding subsea tasks. It has a mall number of components, is oil filled and has a compensated transmission unit. The winches are outfitted with composite rope and they are a reliable and attractive product in the market.

Core Drill Tool for Subsea Structures

The core drill tool is designed to drill Ø100 mm holes in subsea structures by operation from ROV. It has a robust hydraulic transmission, is easy to install and the tool is fastened to the base by activation 4 pcs magnets, alternatively with suction pads or clamping.

ROV Operated Small Bore Hot Tapping Tool & Pipe Squeezer

In order to perform hot tapping for small bore pipes like hydraulic lines, Mechanica has developed an efficient ROV operated hot tapping tool. For operations including blanking of pipes, the hot tapping tool is designed to be operated in combination with the Mechanica pipe squeeze tool.
