Process Vessel Design for FPS
Motion
Edward Brunet, Jr., P.E.
Overview
The motion of Floating Production Systems (FPS) in
response to the motion of the sea presents a challenge for process vessel
designers. The motion of the marine vessel causes fluid turbulence in
process vessels, particularly separators, that can significantly influence the
efficiency of the equipment. The process equipment designer must consider
the impact of vessel motion when selecting the type of equipment to use (i.e.
horizontal vs. vertical separators) and the physical location of the equipment
on the marine vessel. Additionally, modifications to the vessel internals
may be required. In this course, the student will review the six degrees
of motion imposed on floating production systems and the impact of each on
process equipment. Methods to mitigate the effects of motion on process
equipment will then be discussed.
The course material is the
technical paper "Improved Techniques for Wave and Turbulence Control in Process
Equipment" by John J. Byeseda - Technical Manager, NATCO Singapore PTE. Ltd and
Michael E. Clark - Vice President Floating Production, NATCO USA. The
referenced technical paper is reproduced by permission of
NATCO Group.
The student must take a multiple-choice quiz consisting of fifteen (15) questions
at the end of the course to obtain PDH credits.
