Top to Bottom Overhaul for the Crystal Harmony

Cascade General drydocked two cruise ships in the Portland Shipyard this spring, in preparation for the start of the 2000 Alaska season. After the departure of Holland America's Statendam in April, Crystal Cruises brought the Crystal Harmony to Portland for a ten-day stopover in May. The overhaul on this ten-year old ship included maintenance and overhaul work below the waterline, extensive interior remodeling and steel replacement for the pool areas.

In order to maximize the amount of work that can be accomplished during the brief shipyard stay, Cascade General routinely sends advanced crews out to join cruise ships on their way to Portland. On this occasion, the first mobile crew joined the ship in Los Angeles, where work began immediately on an overhaul of one of the auxiliary boilers. A second team embarked in San Francisco to clean ballast tanks prior to structural repairs and tank preservation work.

Within hours of the Crystal Harmony's arrival, rebuilding was under way on the Lido Deck in the pool areas. Once the 790' (240m) ship was high and dry on Portland Shipyard's 982' (299m) Dry Dock 4, work began on all the mechanical systems below the waterline, which were also due for 10-year inspection.

The Sperry stabilizer fins, weighing 27 tons each, were removed to a building bay where they were completely refurbished; both the 1000 kW Lips bow thrusters were extracted for complete disassembly, overhaul and testing in one of the shipyard machine shops.

Multiple paint layers were blasted away to clean the entire hull down to bare metal and a five-coat Jotun paint system applied. Access openings were cut near the keel, to gain entrance to the ballast tanks, where welding crews began replacing corroded steel in several locations.

To comply with Lloyd's rules, over fifty sea valves were overhauled and inspections carried out on propellers, shafting and rudders. In the ship's public spaces, over 125 skilled craftsmen, working for over a dozen sub-contractors, were engaged in a wide-ranging remodeling work.
The Crystal Harmony left Portland Shipyard on May 24 and arrived in Vancouver on May 25 ready to start its first Alaska run for 2000.
