Abstract
This technical report presents results of calm water tank tests on a model of Semi-Autonomous Coaster. The purposes of the tests were as follows:
- determination of resistance and self-propulsion characteristics for two load conditions;
- determination of nominal 3D wake field in the propeller disc;
- determination of optimal trim.
The hull model is manufactured according to the requirements given in the ITTC Recommended Procedure 7.5-01-01-01: Ships Models.
The propeller model is manufactured according to the requirements given in the ITTC Recommended Procedure 7.5-01-02-02: Models Manufacture, Propeller Model
Accuracy.
The propulsion tests were carried out using the external rudder model (provided by its Manufacturer/Designer).
The methods used to carry out the tank tests and to extrapolate the results follow in general the methodology given in the relevant ITTC Recommended Procedures.
The tests are carried out in the deep water towing tank sized 270 m x 12 m x 6 m in length, breadth and depth respectively. The tank is fitted out with a towing carriage of a maximum speed of 12 m/s.
The full scale resistance/propulsion predictions are given for sea water salinity of 3.5%, for the temperature of 15°C.
Description
The tests were conducted for the purposes of a project "Development, construction, and verification in real conditions of a prototype of a semi-autonomous cargo ship for sea navigation", carried out by Nelton Sp. z o. o., Design Department. Project was co-financed under the Intelligent Development Operational Program by the National Center for Research and Development, POIR.01.01-00-0478/18.
