Steady current forces on tanker-based FPSOs Conference Paper uri icon

abstract

  • There is very little information available in the public domain on steady current forces on tanker-based Floating Production, Storage and Offloading systems (FPSOs). The general lack of available data and unresolved issues related to scale effects in model tests bring into question whether the level of uncertainty in modelling of current forces on FPSOs is sufficiently well understood, which has implications for the design of FPSO station-keeping systems. This paper presents the results of a test program to measure current forces on a tanker-based FPSO at various current speeds and relative current headings. While the results are in general agreement with the design curves published by OCIMF, there are some important differences associated with the effect of bilge keels and the effect of lift forces generated by vortex shedding from the bow and stern. © 2005 WIT Press.
