MARINE INDUSTRY
Lo Underwater hull cleaning.
Underwater hull cleaning is the process of removing marine growth, algae, barnacles, slime, and other deposits from a vessel’s hull while the vessel remains afloat
Propeller polishing and repair.
Propeller polishing and repair involves cleaning, restoring, and maintaining a ship’s propeller to ensure efficient propulsion and safe operation.
Underwater Real-Time Photo and Video Survey
Underwater real-time photo and video survey is the inspection of a vessel’s underwater hull and equipment using underwater cameras operated by divers or remotely operated systems.
In water class survey.
In-water class survey (IWS) is an underwater inspection of a vessel carried out while the vessel remains afloat, as an alternative to a conventional dry-docking inspection when permitted by the vessel’s classification society.
NDT. Non-destructive testing, ultrasound measurement and electrolytic test.
Non-destructive testing (NDT) is used to assess the condition and integrity of a vessel’s structure and components without causing damage to the material.
Replacement of parts and electrolytic protection.
Replacement of parts involves removing damaged, worn, corroded, or defective components and installing new or refurbished parts to maintain the vessel’s safety and operational reliability.
Underwater cutting and welding. Plugging and sealing.
Underwater cutting and welding are specialised repair techniques used to carry out maintenance on a vessel’s underwater structure and fittings while the vessel remains afloat.
Precision measurement. Salvage. Support in STS operations. Protection and containment of spills
Provides accurate measurements of underwater structures, hull dimensions, clearances, and damaged areas.
PORT AND CIVIL CONSTRUCTION
Structure cleaning. Structural inspection with photos and video reports.
Structure cleaning prepares the underwater surface for inspection, while photographic and video structural surveys provide clear, documented evidence of the condition and any defects requiring attention.
Destructive and non- destructive tests. Construction and underwater assembly.
Destructive testing determines the performance of materials by testing specimens to failure, while NDT identifies defects without damaging the structure. Underwater construction and assembly enable installation, joining, and repair of structures below the waterline.
Underwater Concrete Moulding, Formwork and Repairs
Underwater concrete moulding and formwork involves installing temporary or permanent moulds and supports to allow concrete to be placed and shaped correctly below the waterline.
Underwater cutting and welding. Surveys and maintenance in hydroelectric dams
Underwater diving services for hydroelectric dams provide inspection, cutting, welding, cleaning, repair, and maintenance of submerged structures, helping maintain dam safety and reduce the need for extensive shutdowns or de watering.
NDT. Non-destructive testing, ultrasound measurement and electrolytic test.
Non-destructive testing (NDT) is used to assess the condition and integrity of a vessel’s structure and components without causing damage to the material.
Precision measurement. Salvage, recover, restore
These services provide accurate underwater measurement, professional recovery of submerged assets, and specialised restoration and repair, helping return damaged or recovered structures and equipment to a safe and usable condition.
Underwater cutting and welding. Plugging and sealing.
Underwater cutting and welding are specialised repair techniques used to carry out maintenance on a vessel’s underwater structure and fittings while the vessel remains afloat.
Launching and commissioning of cables and ducts..
Launching and commissioning of cables and ducts involves the controlled installation, positioning, connection, and testing of underwater cables and protective ducts.
installation and maintenance of beacons and flagging.
Installation and maintenance of beacons and flagging involves placing and maintaining underwater or marine navigation markers used to identify hazards, channels, structures, and restricted areas.
