ANTWERP-HEADQUARTERED underwater repair specialist Hydrex has been carrying out more modifications to a ship's underwater areas and equipment in addition to the company's more common damage rectification work.
The increase in this type of work - to propellers, in particular = follows the introduction of the European Monitoring, Reporting, Verification (MRV) regulation which has seen more shipowners look at ways to further lower fuel consumption and emissions when operating to and from European ports.
The EU MRV regulation entered into force in July 2015. It mandates shipowners and operators to monitor, report and verify CO2 emissions for vessels larger than 5,000 gross tonnes calling at any EU and EFTA port. Data collection requirements became effective on a per voyage basis in January 2018.
An example of the company's performance-enhancing upgrade work was a recent project carried out on a 229 metre long bulk carrier berthed in Bremerhaven. In this case, the bulker's five-bladed propeller was modified to achieve optimum efficiency at lower speeds.
'A major benefit of this approach is that the work is carried out rapidly without the need to take the vessel out of service for drydocking, which is costly in terms of both time and money,' said Hydrex production executive Dave Bleyenberg.
Hydrex engineers are able to carry out underwater repair, conversion and modification work anywhere in the world, in any weather conditions and even in ice.
Before the next winter season, Hydrex engineers carried out a modification programme, altering the blades to a very specific design which would make them less prone to damage from ice and debris, while having a minimal effect on the overall efficiency of the propellers.
