Abstract
    To provide a safe locking process the forces acting on ships during levelling must be kept below  certain threshold values. Due to the limitations of the present measurement techniques Flanders Hydraulics  identified the need of a new technique to validate a lock levelling accurately, safely and efficiently. This paper  describes the pathway of the development of a new innovative measurement technique, supported by the  Programme for Innovation Procurement of the Government of Flanders. A preliminary study concluded the  absence of an off-the-shelf solution but pointed out some possibilities for new developments. Within the project  two different possible techniques have been explored. The objective of this project is to identify the suitability  of these techniques by means of Proof of concepts. Apixa explored a technique based on stereovision, Iv-Infra  explored a technique based on tachymeters tracking prisms positioned by drones. The real Proof of Concept  of both techniques was executed in October and November 2023 in an ECMT class IV lock. During both Proof  of Concepts reference measurements were carried out by Flanders hydraulics and The General Technical  Support Division. By the time of writing of this paper the measurements of the Proof of Concepts are being  processed. The preliminary results look promising but further processing and analysis is needed.
