Planning logistics for pipeline construction exemplified for the Brokdorf power station

The Mannesmann Anlagenbau AG company (MAB) shows the utilization of up-to-date project logistics by means of EDP exemplified by their working activities with the construction of the Brokdorf nuclear power plant. The MAB was commissioned to deal with pipelining the nuclear power plant including the packages of construction and design, supply, manufacturing, assembly, project management and quality safeguarding. About 56,000 m pipelines plus c. 69,000 accessories like shaped parts, valves and fittings and mounts are to be placed. The number of welded seams mounts to c. 60,000 which require c. 400,000 checks with a total of more than 1 million testing steps to be performed and documented. MAB developed their own EDP programme system (System 84) which consists of individual programme modules covering special tasks. The bulk of calculation is run in dialog operation on a computer (Prime 2250) installed on the site. The construction site computer is connected to other computers via public telephone lines. It can be dialled externally so that authorized subjects or bodies can scan the state of the project from outside the site at any time. (orig.)
