Dear all,
Got a couple of quick questions for the brainstrust.
1) Why did the Olympic Class use firetube boilers and not watertube? Watertube boilers had been around since the late 1800s and were well established in warships. Was the cost vs performance just not worth it?
2) I have been following some naval podcasts recently and it is mentioned time and again that vertical triple expansion engines could not run at full speed for any length of time due to vibrations causing damage. Therefore a vessel with a top speed of 20 knots could only run at that speed for a short period of time. I would however note that the Olympic class seemed to have no problems ploughing at full speed across the Atlantic for days at a time with no detrimental effect. Can anyone confirm/deny?
Many thanks!
