EXPERIENCES IN THE USE OF PHOTOGRAMMETRY IN SHIP PRODUCTION

During 1974-75, the Stralsund shipyard in East Germany, a well equipped yard specialising in the series building of large fishing-vessels, carried out investigations aimed at identifying the causes of geometrical and dimensional discrepancies that may occur in parts and assemblies during fabrication, transport, and erection; the need to rectify such discrepancies adversely affects production flow. Industrial photogrammetry was the method chosen for checking the dimensions and form of the larger hull-sections, stereo-photographs being taken at intervals during the course of production to enable any relevant qualitative and quantitative effects of the processes to be ascertained (e.g., the effect of welding, or the possible effect of transportation, upon the geometry of the abutting contour of a section). The photogrammetric results were processed (by the Shipbuilding Institute, Rostock) with a computerised Carl Zeiss Jena system, which includes both hardware and software. The output can be in the form of a data list and is also available (with the aid of a numerically-controlled draughting machine) in the form of a scale drawing. The Authors describe the methods used at Stralsund, mention some possible improvements in accuracy and effectiveness, and briefly discuss the shipyard use of photogrammetry in the light of the investigation. Some recommendations are made on the shipyard applications for which these techniques are most suitable, and some practical difficulties are mentioned. Experience at Stralsund has shown that photogrammetry can contribute to the achievement of smooth-flowing and economic production.
