Tech/Engineering - Ships, Sailing, Maritime / boat technical specification
French term or phrase: Vitesse en service
Vitesse en service:

From a form to be filled out by the manufacturer or importer of a boat built outside France to obtain a registration number in France.
The form lists all the boat technical specification; such as:
- Nombre maximum de personnes à bord
- Déplacement lège
- Mode de propulsion
- Nombre et types d'hélices
- Vitesse en service

"Vitesse en service" is the last line and is the only line concerning/mentioning the speed.

Does it mean "operation speed " ? other ?

Thanks for your help.

Asker: Thanks Florence, do you think it could have anything to do with the MAXIMUM sailing speed ?

  -> If you search "vitesse en service" in ship specifications, I think it is quite clear that it means cruising speed.

"Below the waterline, the forward engine room was dismantled and the two outboard propellers were removed to reduce fuel consumption as a high service speed was no longer required as she was now a cruise ship."

"Her engines consisted of eight high-pressure, super-heating boilers delivering 64 bars (930 psi) of pressure and 500 °C (932 °F), all weighing 8,000 tons. This delivered 175,000 horsepower (130,000 kW) and provided for a service speed of 30 knots (56 km/h; 35 mph) and a maximum speed of 35 knots (65 km/h; 40 mph), with a fuel consumption of 750 tonnes of oil in a 24-hour period. The machinery turning the four propellers was divided into two fore and aft groups, as was the electrical generating station.[4]"

"Calculation of the mean long-term service speed of transport ship: Part II Service speed of ship sailing on regular shipping route in real weather conditions

Calculation of the mean long-term service speed of transport ship: Part II Service speed of ship sailing on regular shipping route in real weather conditions

Service speed obtainable by a ship in real weather conditions when sailing on a given shipping route, is one of the major parameters which have great impact on ship operation costs. The so far used, very approximate method of service speed prediction based on "service margin", is very little exact. In this paper a new method based on additional ship resistance dependent on mean statistical parameters of wave and wind occurring on a given shipping route, is presented. The mean long-term service speed is calculated on the basis of the calculated additional resistance and the screw propeller and propulsion engine parameters. Also, a new definition of service margin and a way of its calculation is presented apart from the results of the mean service speed calculation depending on ship's type and size and shipping route."
