In accordance with contractual require- ments, the vessel has been engineered and faired to maintain at least 21.1-knots on the design draft at 85 percent engine output, with 20 percent sea margin. The fact that she achieved more than 23 knots on trials is an indication of her latent power, but the expecta- tion that she will be able to keep to 21 knots even in conditions where existing trailerships of 17-19 knots have to slow down is no less salient to the operation. Tor Selandia provides the first sea-going ref- erence for the ZA50S engine, a continuation of the Swiss-developed Sulzer medium-speed lin- eage within the Wartsila NSD portfolio. Remarkably compact in relation to their out- put, the two nine-cylinder models employed in the Swedish vessel rank among the world's most powerful in-line, four-stroke machinery. Manufactured in north-east Italy by Grandi Motori Trieste (GMT), a partnership of the vessel's builder and engine licensor, the prime movers deliver a total 29,340-bhp at 450-rpm, driving twin, highly-skewed Kamewa controllable pitch pro- pellers through a Renk Tacke reduction gear- box. Although it incorporates many of the lauded features of the popular ZA40S engine, a unique feature of the latest design is the adop- tion of hydraulic actuation for the gas exchange valves, commonly employed in low-speed two-stroke machinery, but hitherto not used in the medium-speed domain. In the ZA50S, it is used in conjunction with pneumatically-controlled, load-depen- dent timing to provide variable inlet closing (VIC). One result is a low level of exhaust emissions, an ever-more pressing consid- eration in the short-sea trades in partic- ular, such that the installation falls well within the IMO year 2000 limits pre- scribed for nitrogen oxide (NOx) output, while giving a substantial reduction in smoke emis- sions during part-load engine running. The other major result is improved fuel economy, with a flat fuel consumption profile across the engine's load range.
