The world's first ocean-going motorship was the Dutch motortanker m.s. "Vulcanus", built in 1910 by the Nederlandsche Scheepsbouw Maatschappij of Amsterdam for the Nederlandsch-Indische Tankstoomboot Maatschappij, a Dutch Royal Dutch/Shell company. Her main engine was built by Werkspoor, also of Amsterdam. The engine was a single-acting six-cylinder four-stroke crosshead with blast injection. Further particulars:
Bore x stroke: 400 x 600 mm.
Output: 450 BHP at 180 rpm.
BMEP was 4.95 kg/cm2, piston speed 3.6 m/sec.
"Selandia" (and B&W) may have received all the publicity over the years....... but she most definitely was NOT the first!!!!!!!!!!
