MANTA RAY


MANTA RAY patented marine anchors are driven into the earth by hydraulic handheld jackhammers (breakers). The anchors do not disturb the soil upon installation, but actually compacts the soil around itself when being driven.
After driving, the anchors are tipped into "anchor-lock" position in disturbed soil using MR anchor locker. This provides a prooftest of the anchor, which immediately tells the installer the holding capacity of the soil. This removes the guess work from anchoring.

Hull Condition Inspections

This important function can be undertaken through the use of either ROV’s (Remote Observation Vehcile) which is a diverless operation OR through the deployment of qualified divers with hand-held video and still-camera.  Both methods of observation can be relayed to the surface in real time on closed circuit TV monitors.
