Abstract

I en fremgangsmåte for måling av strekkraften i en stolpeløs kjetting (6), så som en ankerkjetting for en flytende offshore-konstruksjon, blir en løkke (7) av kjettingen fastholdt i en kjettingstopper (10) i en jekkevinsj mens en ovenforliggende kjettingløkke (11) senkes ved hjelp av jekkevinsjens løfteanordning (14) slik at det oppstår en åpning mellom den øvre bøy (18) av den fastholdte løkke (7) og den nedre bøy (15) av den ovenforliggende løkke (11). En lastmåleanordning (1) omfattende en kompresjonslastcelle (2) blir så innsatt i denne åpning, hvorpå løfteanordningen (14) strammer opp kjettingen slik at kraftmåleanordningen (1) klemmes fast mellom nevnte bøyer (18, 15) og opptar hele strekkraften (F) ved videre heving av løfteanordningen (14). Strekkraften kan avleses i en bærbar anordning (17) tilkoblet lastcellen (2). Strekkraften kan også avleses under den påfølgende senkning av løfteanordningen (14) for å frigjøre kraftmåleanordningen (1). En kraftmåleanordning (1) egnet for utførelse av fremgangsmåten er også vist.In a method of measuring the tensile force of a postless chain (6), such as an anchor chain for a floating offshore structure, a loop (7) of the chain is held in a chain stopper (10) in a jack winch while an overhead chain loop (11). ) is lowered by means of the jack winch lifting device (14) so as to create an opening between the upper bend (18) of the retaining loop (7) and the lower bend (15) of the above loop (11). A load measuring device (1) comprising a compression load cell (2) is then inserted into this opening, whereupon the lifting device (14) tightens up the chain so that the force measuring device (1) is clamped between said buoys (18, 15) and absorbs all the tensile force (F) at further raising of the lifting device (14). The tensile force can be read in a portable device (17) connected to the load cell (2). The tensile force can also be read during the subsequent lowering of the lifting device (14) to release the force measuring device (1). A force measuring device (1) suitable for carrying out the method is also shown.
