Hull Cleaning include Cleaning of Vessels, Rigs and OffShore Platform. Fuel consumption is one of the main reasons for hull cleaning; the fuel occurring cost is over half of the ships operational cost. For under water hull cleaning, Propeller Polishing and Maintenance of Ships, Indus Divers exploits their complex Technology as well as methods of cleaning and polishing using hydraulic cleaning machines which can give a surface finish of 1-2 micron CLA (Rupert grade "A" or better)

NDT Hull thickness determination surveys now permitted by classification societies up to one year before the second and subsequent special surveys become due are facilitated by water, which forms an ideal ultrasonic medium. Accurate gauging can be taken by divers without the need to remove paint coatings. It is not uncommon, Indus Divers reports, for a team of three divers to take 500 - 600 readings in a day.
