Holland-America Selects Sulzer Diesel Engines For Its Two Cruise Ships

Sulzer low-speed, two-stroke engines have been specified for main propulsion and auxiliary duties for two 32,000-grt, 30,500-bhp passenger cruise ships recently ordered by Holland-America Line from the St. Nazaire Shipyard of Chantiers de 1'Atlantique. With fuel costs forming a major factor in ship operating costs, the owners have planned a machinery installation to ensure overall economy, in particular in fuel bills and maintenance and with special regard to low noise level.

After detailed studies of various classes of main and auxiliary machinery and systems, Holland-America, with Chantiers de 1'Atlantique, have ordered for each ship three Sulzer crosshead-type two-strokes, all to burn heavy oil. Two are for main propulsion and the third to drive two electric alternators.

It is the first time in many years that two-stroke crosshead-type engines have been used for auxiliary power generation.

The reasons in this case are low consumption on low-grade fuel oil and fewer cylinders and moving parts to maintain.

The propulsion engines, to be built in the CCM-Sulzer plant at Mantes-la-Jolie, will be of the newly developed 7RLB66 type, each rated at 15,225 bhp (11,200 kw) at 140 rpm.

Each of these seven-cylinder "small-bore" engines is, however, optimized for fuel economy reasons for 14,680 bhp (10,800 kw) at 135 rpm.
