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.
