Danish coatings manufacturer Hempel has launched an underwater hull inspection service using Remote Operated Vehicles (ROVs), while a vessel is at port or anchorage.
Under the Hull Inspection Service, inspections are conducted by an expert Coatings Advisor operating an ROV which is navigated around the vessel’s hull using remote-controlled thrusters. The ROV captures high-resolution video footage and still images of the hull for assessment in real-time.
The ability to utilise remote hull inspections through the deployment of highly sophisticated and purpose-built ROV’s is a significant step-change in the ability to create advanced hull maintenance plans,
…explains Klaus Moeller, Group VP, Head of Services.
According to Hempel, using ROVs for hull inspections simplifies the process and allows for more frequent and less costly hull inspections. As no divers are required, inspections can be conducted without the need to shut down vessel systems. This makes it possible to complete hull inspections in two hours or less even alongside cargo loading or discharge.
Hull fouling is a significant contributor to speed loss and at its worst, has the potential to increase engine power requirements by close to 20 per cent over five years. Being able to routinely and consistently monitor hull condition between routine dry-dockings with ROVs enables shipowners and operators to implement an appropriate maintenance schedule which optimises vessel performance,
…comments Christian Ottosen, Group VP, Head of Marine Business.
Initially available in selected ports of China and Korea, the service will be extended to key maritime hubs worldwide in the near future.
