Tripping Joint Industry Project for Propeller Scale Corrections

This document is a technical report detailing the objectives and scope of the Tripping Joint Industry Project (JIP) proposed by MARIN. The primary aim of the project is to develop new scale corrections for propellers to enhance the accuracy of full-scale predictions for both open water and propulsive performance. The report outlines the motivation for the project, which includes reducing uncertainties during model tests and improving propeller designs for manufacturers, ship owners, and research institutions. The document describes the planned methodology, which includes conducting open-water model tests with turbulators to achieve turbulent flow, performing RANS computations for a wide range of Reynolds numbers, and developing a generic scale correction method. The project is structured into four work packages, each focusing on different aspects of propeller testing and analysis. A timeline for the project is also provided, indicating a three-year duration with a kickoff meeting scheduled for November 2023.
