Ship Repair & Conversion Cascade General Gets Crystal Harmony Back In Sync Subsequent to the departure of Hol- land America's Statendam in April, Cas- cade General took in Crystal Cruises' Crystal Harmony for a 10-day stopover in May. The 10-year-old ship underwent maintenance and overhaul work below its waterline, extensive interior remodel- ing and steel replacement for pool areas on Deck 11. With maximization of work in mind. Cascade normally sends advanced crews to join cruise ships on their way to the yard's Portland, Ore. locale. This time though, the first mobile crew met the ship in Los Angeles, where work commenced immediately on an over- haul of one of Harmony's auxiliary boil- ers. A second team was then summoned Call for a free catalog or to order our demonstration video.

Measuring 790 ft. (240 m), the vessel was dry- docked at Cascade's 982 ft. (299 m) Drydock four, beginning with the mechanical systems below the waterline. Sperry stabilizer fins, each weighing 27 tons were removed to a building bay for complete refurbish- ment, while the 1,000 kW Lips bowthrusters were taken out for com- plete disassembly, overhaul and testing in one of the shipyard machine shops. Multiple layers of paint were blasted away to clean the hull down to its bare metal so that a five-coat Jotun paint sys- tem could be applied. Welding crews replaced corroded steel in several loca- tions, and more than 50 sea valves were overhauled and inspections performed on propellers, shafting and rudders for Lloyd's Register compliance.

Taking immediate action was the Colombo Engineering dive team who was summoned to examine the 20 Puget Sound ROPE PLASMA 12 x 12 50% Stronger, 20% Less Expensive, And It's Repairable.

Using a JW Fisher DV-2 underwater camera system, the group was able to shoot an underwater video inspection that was then observed by an agent of Lloyd's Register of Shipping, who in turn discovered that one of the vessel's four propeller blades had been sheared off. The JW Fisher camera allowed the shipping agent to perform an accurate assessment regarding the problem as well as the necessary repairs involved. Actions taken were that the propeller blade opposite the sheared propeller blade should be cut off to balance the rotation. Immediate action was neces- sary, as the drive shaft bearings would 20 Maritime Reporter/Engineering News
