Shelf Subsea owns a single mast and dual mast diver-operated drilling rig for coring and pipeline stabilisation (rockbolting).

Our single mast PQ3 coring rig has been operated by divers in Saturation (65m of water) achieving 70m cores whilst our dual mast rock bolting rig has installed over 1000 pairs of 5.5 metre bolts on multiple subsea pipelines.

Shelf Subsea can also offer a number of unique, innovative Geotechnical sampling solutions for seabed investigation, whether it be for bulk seabed sampling or the removal of overburden with our mechanical Clam Shell Grabs or smaller samples with our diver operated Push Tube sampler.
