HC Deb 06 March 1912 vol 35 cc373-4

asked in what way the power of motor and oil engines is computed for the purpose of entry in the register of shipping; whether a formula assuming a certain steam pressure is still used; and whether, as there is no steam pressure in either motor or oil engines, the advisability of devising a new formula for both types, which will give an approximation of engine power, will be considered?


Vessels fitted with motors or oil engines and registered in this country are as yet of small tonnage; and the power of the engines given on the certificate of registry is that stated on the certificate supplied by the engine makers. No formula assuming a certain steam pressure is used by officers of the Board of Trade for deciding the registered horse-power of motors or oil engines. It is probable that, in the near future, vessels of considerable size, fitted with internal combustion engines, will be built for registration in the United Kingdom; and, in that case, the necessity of framing a suitable formula for determining the registered horse-power will be considered.
