Abstract
Voor het bepalen van de risico's van brandstofpontons
in een jachthaven is een generieke risico-analyse uitgevoerd. Er is een
referentiesysteem gedefinieerd, bestaande uit een betonnen brandstofponton
met een relatief grote inhoud en doorzet. Aangenomen is dat de ponton
gelegen is in een jachthaven waar alleen pleziervaart aanwezig is, en dat de
tankauto tijdens het lossen beschermd is tegen externe beschadiging door
langskomend verkeer. De kwantitatieve risico-analyse is uitgevoerd conform
de standaard rekenmethode van het Paarse Boek. De referentie
brandstofponton leidt tot individueel risicocontouren van 10-5 per jaar en
10-6 per jaar, die praktisch samenvallen. De afstand van deze contouren tot
de brandstofponton en de tankauto bedraagt ongeveer 20 meter. Het risico
wordt voornamelijk bepaald door de plasbrand binnen de brandstofponton en de
breuk van de losslang bij verlading van tankauto naar
brandstofponton.
A generic, quantitative risk assessment was carried out according to the standard method in the 'Purple Book' to determine the risks posed by pontoons used for supplying fuel to watercraft. The pontoon is assumed to be situated in a yacht basin accessible only to pleasure boats, and the tank lorry during unloading assumed to be protected against external impact from passing traffic. The reference system defined consists of a concrete pontoon with a relatively large capacity and a high volume of trade. Applying the reference pontoon system led to individual risk contours of 10-5 and 10-6 per year, which almost coincide. The distance of these risk contours to both the pontoon and the tank lorry is about 20 metres. The risk posed by the pontoon is largely determined by the pool fire within the pontoon and a rupture in the loading hose, which could take place during transhipment from the tank lorry to the pontoon.
