Hydrex Underwater Technology has assisted an excavation vessel hemorrhaging oil from a stern tube seal entangled with steel wire to pass safely through the Panama Canal. The 156m long, Dutch-owned vessel was unable to make the canal transit until the propeller shaft seal had been repaired, potentially delaying operations and resulting in financial penalty for the owner. Antwerp-headquartered underwater ship repair specialist Hydrex, however, repaired the leaky seal allowing the vessel to continue without disruption to its schedule.

Underwater repair specialist Hydrex says when hull damage leads to the classification society to only allow temporary repair, there is a practical solution that allows ships to continue operations until a permanent repair can be scheduled. Recently called upon to inspect damage to the stern thruster area of a 195m ro-ro ship during a scheduled stop in Antwerp, the Hydrex investigation revealed a large crack in the welding seam on the edge between the hull plating and the thruster tunnel. To repair the vessel, Hydrex was able to fabricate a 600mm x 300mm doubler plate, on-site.

Antwerp Port Authority has supported Hydrex Underwater Technologies’ plan to expand its existing 5000m² site on Asiadok on the River Scheldt with new workshops and offices.

Hydrex Chairman Boud Van Rompay said, “The new facility together with our recent recruitment drive is consequent of market demand for swift and cost-effective underwater hull and running gear care.

Belgian underwater repair specialist Hydrex says it is 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 recent introduction of the European MRV regulation which has seen more shipowners look at ways of further reducing fuel consumption (and emissions) when operating to and from European ports. The EU MRV (Monitoring, Reporting, Verification) regulation entered into force in July 2015.
