Subsea Engineering & Repairs
Our diving services include underwater inspection, underwater cleaning, CCTV underwater video survey, mooring system installation, underwater video and still photography, search and recovery, hull cleaning, aquaculture diving, media diving, pool cleaning and repair, underwater mapping and light civil engineering.
Underwater inspections are primarily visual observations of the facility being inspected. Quantitative measurements, such as underwater voltmeter readings on metal structures and thickness measurements on mooring chain and steel piling, are often taken. Before making the observation, it is usually necessary to clean the structure of marine growth and fouling. Several techniques are used to accomplish this cleaning, ranging from hand cleaning with scrapers and wire brushes to the use of water blasting jets and hydraulically powered mechanical abrasive tools.
It can be performed by following methods:
Visual Inspection
ACFM Inspection
Remote Visual Inspection
