Mooring Chain Cleaning & Gauging

Using a Mini-ROV to clean, visually inspect and caliper-gauge mooring chains in the field. This inspection can be carried out on FPSO’s, Semi’s, CALM Buoys, etc.

UWILD of Drillship Thruster

This video shows an Underwater Inspection in Lieu of Drydocking (UWILD) of a deep-water drillship. This inspection was carried out while the drillship was in D.P. (Dynamically Positioned) operation and attached to the drill string, causing no disruption to operations. The DNV surveyor in attendance gave full UWILD credit to the vessel owner without any divers entering the water.

Critical Hull Weld Cleaning

As an offshore platform gets older, the need to closely expect critical hull welds becomes more important. But, just as inspection requirements increase, so does the marine growth that obscures inspection. The ability to clean marine growth is a necessary precondition of a successful underwater survey but until recently was the domain of only larger ROVs.

Proceanic has successfully adapted this technology to mini-ROVs which can be hand launched. As a result, we can carry out the inspection at a fraction of the cost and with minimal impact on operations.

Sea Chest Cleaning

The mini-ROV can be used to perform localized cleaning of your vessel while offshore and in operation, such as needed for sea chests and spot cleaning of welds for visual inspection.

The mini-ROV is able to do this while still remaining hand-deployable, thus enabling it to operate in situations where larger ROVs would not be able.

Close Up Survey

This video shows the ROV performing close-up survey of an FSO tank internals. Video is taken using a supplementary high-definition camera mounted atop the ROV. High definition video provides the clearest possible documentation of the condition of the tank structure and coatings.

ROV Side Shell Gauging

This video shows the ROV taking girth belt gaugings on side shell. Initially, one pass is made to take the plate and flange gaugings. Then, the gauge is aimed downwards, and another pass is made to capture web plate gaugings

General Visual Inspection

General visual inspection (GVI) is performed of the ballast tanks of an offshore spar platform. The GVI was approved by ABS and USCG.

Tank Gauging

Gaugings taken of an offshore spar platform to perform verification of as-built scantlings. Video shows text overlay of thickness reading from gauge. All video is recorded, and all videos and photos taken during the inspection are delivered to the vessel owner.

Hull Cleaning with Magnetic Crawler

Proceanic’s proprietary magnetic hull crawler is used to perform wide area cleaning of a ship’s shell plating and seachests. The cavitation cleaning dome is powered by a high-pressure pump located on the main deck.
