SUBPRO Subsea Production and Processing
separation concepts and ideas worth pursuing will
be performed. There are two concepts analysed
previously at NTNU that might be looked into:
separation in spiral conduit and separation in an
inclined pipe using distributed tapping.
At a later stage, the research will select the
most promising concept to develop further (in
agreement with the industrial partners) and
will perform experimental measurements and
numerical simulations to determine separation
performance.
Status:
The project will start mid-2016, due to
limited availability of qualified PhD candidates in
the first announcement round.
The originally proposed work plan has been
revised, considering the delay. The laboratory
facilities have been planned and prepared at the
end of 2015.
The main objective of this project is to perform an
experimental and numerical evaluation of primary
separation techniques for oil and water flows
with potential for subsea implementation. The
techniques to be analysed should be robust, effec-
tive and have low energy requirements.
At an early stage, the research will perform a
systematic evaluation of existing systems and
methods for subsea separation using input from
existing projects and from industrial partners.
Afterwards a screening and pre-evaluation of new
