FPSO vaning new challenge

This project not only constitutes a new challenge in terms of weather being bad. But also adding the fact that the FPSOs we are operating around, are moving around a "turret". A kind of "wheel" in the centerline, and often in the most forward part of the vessel. This "wheel"(turret) is secured to the bottom with anchor/wires, and all the connections to the sub sea structures, raisers etc. runs up thru this "turret". The vessel itself is free to move around the turret, drift in whatever direction the wind and surface current pushes it (Vaning). Sneaking up close to this structure is tricky. We have to asume that the current or wind, could suddenly change and set the structure drifting towards us. With our gear deployed and a top "warp speed" of 0,3 knots, makes us on the bridge stay very alert and carefully monitor the movements of "the creature". To spice it up, one of these FPSOs have a 345 meter long
"export-hose"  vaning from its stern. When this hose change direction, is the first indication of that something is in the making.
 
Detta projektet utgoer inte bara en utmaning naer det gaeller vaeder. Daer till kan laeggas att de flytande produktionsplatformarna som vi arbetar runt och under, inte aer fast foerankrade utan roer sig omring en s.k "Turrett". Ett slags "hjul "belaeget i centerlinjen ofta laangt foerut i fartyget. Detta hjulet(Turreten) aer foerankrad med wire och ankare i havsbtten, och all kontakt med undervattens strukturer och "raisers" gaar upp igenom detta hjul. Fartyget sjaelvt aer fritt och roer sig 360 grader runt detta hjul, vartefter stroem och vind saetter det. Att arbete taett intill detta "shabrak" aer lite trixigt. Man maaste ju foermoda att fartyget ploetsligt skall komma drivande emot oss. Naer vi har all utrustning sjoesatt saa kan vi endast faerdas i 0,3 knop, saa vi paa bryggan aer lite paa helspaenn vid de tillfaellena. Som graedde paa moset saa har en av dessa godingar dessutom en "export" slang paa 345 meter faest i haecken. Saa naer den rackarn aendrar riktning, aer det en god indikation paa att naagot aer paa gaang.
