Safe and cost effective ship-to-ship operations in Arctic waters

Tildelt: kr 4,3 mill.




2007 - 2011




The project aims at developing a set of common Russian - Norwegian guidelines for STS operations. This will enable Norwegian interests to have a commanding role in such a development, and to become competitive and attractive partners for later projects in the Arctic area. The project will also provide the project partners with an unique opportunity to establish solid relations with important Russian interests for further development in the Arctic area. The following sub goals will be addressed: 1) Colle ct Ice-metocean data for potential STS loading areas, as well as models for use in Arctic design and operation 2) Describe alternative STS designs (Tandem, Side by Side and Longer by Side), and define operational limits based on data and models for use in Arctic design and operation (from 1). Also investigate technical and operational challenges. 3) Select STS design and location(s) based on calculated system performance, with focus on high safety performance and minimum downtime. Input to the modelling will be location specific Ice-metocean data. 4) Develop an operational procedure for each operational phase based on 1) and 2) The project proposal will focus on the last challenge, ship to ship transfer of LNG/LPG. For this operation a number of theme s need to be investigated: - Selection of STS mode, side-by-side, longer-by-side or tandem configuration - Vessel control under approach/separation manoeuvres - Vessel control during cargo transfer - Relative vessel motions - Design of mooring system - Sloshing in partly filled cargo tanks - Motion of and forces in cryogenic loading hose - Downtime due to operational limits and reliability of system components The project group consists of major norwegian maritime cluster partners representing ship own ers, equipment manufactorers, classification and research. The Russian partners are Gazprom and Gazflot.
