Speed-power performance prediction
General information
In the early stages of ship design, an initial speed-power prediction can be made by MARIN to verify whether the hull design is good enough to enable the ship to attain its contract speed at a specified draught, trim and power. Such a prediction is made on the basis of a large database that MARIN owns, which contains the results of many model tests as well as full scale ship sea trial results, either measured by MARIN, or by a third party and supplied to MARIN.

Services & Activities
The Resistance and Propulsion experts have a vast expertise in the field of speed-power predictions for ships. The available data not only concern conventional single and twin screw displacement ships, but also semi-planing and planing craft, ships propelled by pods and /or azimuthing thrusters and waterjet propelled craft.

Facilities & Tools
The following tools are used to make speed power predictions:
