gines with integral thrust bearings, each coupled directly to KaMeWa controllable-pitch propellers having a highly skewed blade design. The main engines each have a maximum continuous rating of 15,770 bhp at 140 rpm.

The Siemens propulsion control system, which includes automatic main engine overload control as well as an engine load increase feature, incorporated different operating modes, including: constant-speed operating mode at 136 rpm for shaft alternator operation; and two com- bination operating modes—one thrust mode and one pitch mode— where the engine speed, propeller thrust, and propeller pitch are con- trolled according to a pre-estab- lished curve.

At sea, the Jubilee will normally operate in the constant-speed mode at 136 rpm, and the shaft-driven alternators will feed the main switchboard. As it is not the inten- tion to run the two shaft alternators in parallel, the main switchboard is capable of being operated in a "split" mode by means of a section

The vessel's hull form has been developed to give good propulsion and seakeeping performance with due regard to the large propeller tip clearance requirements at the vari- ous design conditions. The lines were designed to give the smallest possible resistance, with the bul- bous bow designed for a draft of 24.6 feet and optimized for a service speed of 19.5 knots.

Except for certain parts of the public spaces, where special features are introduced, Dampa continuous ceiling systems consisting of pre- stressed, baked enamel steel/alumi- num panels are used throughout the accommodations, and Ecomax has been used throughout for linings (bulkhead panels). Sound-absorb- ing decks consisting of mineral wool slabs with steel tops are installed in the crew accommodations above the engine rooms as well as below the bandstand and dance floors to pro- vide maximum insulation against noise.

The Jubilee is the first large pas- senger vessel built by Kockums, soon to be followed by her sister ship Celebration scheduled to be delivered at the end of Janaury 1987:
