Power of the engines
I've updated the text to show the power of the 4 engines combined as 9650 kW, which is given in several publications (including the one I cited in the article). As Sulzer is a European company a value specified in metric units seems more credible. The prior figure, 3177 NHP, seems to have come from the Lloyds Register cited in the article, and it has two problems: one is that NHP is something more usually applied to steam engines in the early days of steam ships, not diesels; and the other is that it never has any relevance to the actual power of an engine. In fact, in 1936 "The Motor Ship" described Lloyds practice as "Briefly, then, N.H.P. in the Register represents a figure which is a measure of the amount of work entailed in the surveyor’s inspection of the machinery of a ship. It affords a basis for computing the fees to be charged for the survey and not the actual power of the engine; or anything like it, for that matter." https://www.shipsnostalgia.com/threads/nhp.115826/ 2601:589:300:CA70:A8C7:6023:7DB4:25BA (talk) 23:09, 26 January 2023 (UTC)
