radius of operations would increase four times. Or you can put weight savings into increased armour, ammunition or firepower. However, it is Flannery’s prophetic forward
view that really shows the understanding of the members of the importance of Selandia: “She [Selandia] has cylinders of just under 21in in diameter. She develops 2500 Indicated Horsepower (IHP) in her main engines [16 cylinders]; that is, roughly about 160 HP in each cylinder of 21in in diameter. If you compare that with a steam cylinder of the

understood very well that this was the beginning of the revolution and that far more was to come: “Te development, therefore, is to be found in doubling or quadrupling, as you ultimately will, the power that can be produced from a cylinder of a given size. Tese are four-cycle engines in the Selandia. The next step, which our friends on the Continent are working very hard to attain, will be to introduce the two-cycle engine. Tat will double the power. Aſter that the next step will be in double-acting instead of the single-acting engine, and that will give you, with engines of practically the same size and of no greater weight [although, possibly in the first instance, somewhat greater
that in the comparatively near future that result [10,000HP] will be attained…when it is attained, we shall probably be quite sure that we have reached the stage when steam-propelled vessels will have become obsolete.” And enthusiastic members were not to
be disappointed by Selandia as Knudsen reported to them through a written response to their discussion on the vessel’s first voyage aſter leaving London: “During the voyage from Antwerp to Gibraltar the vessel encountered very high seas, and during 48 hours the propellers were racing continually. Te Aspinall Governors, fitted to the engine, worked excellently and kept the revolutions at from 120-130 up to 150. Te heavy sea had, in fact, no influence on the good working of the machinery.” NA

cash flow for marine related projects. Those attending the course will be better able to identify the pitfalls and traps experienced within the industry, and be more prepared to identify all the costs,schedule changes and to properly assign responsibilty for those changes and effects. This will save companies considerable sums in each major contract.
