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.

Harad

Harad is the first in a four-ship double-hulled series of VLCCs constructed for Hellespont of Greece by the South Korean builder Samsung Heavy Industries. During construction, the four vessels were re-sold to NSCSA of Saudi Arabia. The vessel, which incorporates a number of technical features to ensure high levels of environmental protection and high performance, holds a large main engine, improved strength by increased plate thickness, improved service lifetime for coatings by increased paint specification and advanced inert gas system. The hull form of the vessel has been specifically remolded to meet Hellespont's requirements and differs from the conventional VLCCs, featuring a 'blunt' fore part and a breadth of 190 ft. (58 m) to reduce hull deflection.
