Improved dynamic positioning for large vessels to increase safety and effectivity in offshore operations and exploration and exploitation of marine resources (DP-JIP)

Deliverables

The report describes the three stages in the DP system design of a DP ship: initial, detail and as built. The required accuracy of engineering data and regulatory requirements is discussed for these phases. The second part of the report describes the effect of using RTEFE technology on the design process.
The report describes the findings of the R&D work to develop, test and validate on model scale the RTEFE technology. Additionally, the results of full scale measurements are discussed, which were carried out to assess the applicability of model scale results for full size conditions. It concludes that the RTEFE method is sufficiently robust to be applicable and will improve DP performance of the vessel.
The report describes the CAPEX and OPEX of a 1 million bbl FPSO for a typical deepwater area. A conventionally moored FPSO is compared with a DP FPSO with and without RTEFE technology. The DP FPSO concept is capable of station keeping in the 100-year storm condition and power generation for DP and process is optimised.
