A CORRECTION METHOD FOR SHALLOW-WATER EFFECTS ON SHIP SPEED TRIALS
In July 2021, the 29th ITTC conference accepted a new procedure to correct ship speed trials results for the effect of shallow water, under the name ‘Raven shallow water correction’. Adoption of this procedure was proposed by the ITTC Specialist Committee on Operation of Ships at Sea [ITTC 2021a]. The same correction method is also included in the 2022/2023 revision of ISO15016 “Guidelines for the assessment of speed and power performance by analysis of speed trial data”.
To guarantee that the meaning, background, limitations and possible refinements of the correction procedure are clear and generally accessible, a summary report has been written and published. This report aims to collect all information available now, including the steps taken to develop and validate the procedure. It collects the main information from several previous papers by the present author; adds several new checks and comparisons; and discusses all validations done and that could be found in the literature.
The report is being sent to those we know are involved, and can be downloaded here:
