"They that go down to the sea in ships, that do business in great waters; these see the works of the Lord, and His wonders in the deep...He raiseth the stormy wind, which lifteth up the waves...they reel to and fro and stagger like drunken sailors!" (psalm 107)

Napier Deltic Engines

Napier Deltic Napier Deltic

The Napier Deltic diesel engine adapted for marine use (18-7A overhaul life 4000 hours) - the gearbox is actually a gear phasing unit for three crankshafts as this engine is configured like a Y with 3 banks of 6 pistons - an 18 cylinder two stroke diesel engine. Before cold starting the crank had to be turned 100 revolutions by hand to build up oil pressure and to ensure there was no water between the pistons which would cause the engine to hydraulic at start up, and bend connecting rods which might break at a later date. These engines were started by firing a cartridge or at sea by 'trailing in' the second engine.
