IMHO..from the "Nautical Insitute":http://www.nautinst.org/index.htm
"VALIDITY OF CERTIFICATE
The Dynamic Positioning Operator’s certificate remains valid as long as the
holder operates DP systems regularly. This is defined as a minimum of six
months DP watchkeeping experience within the previous five years. Should a
period of five years elapse and the holder does not serve aboard DP vessels
and operate the DP equipment, the holder should recommence the training at
the Simulator/Advanced course and complete all the requirements there after.
On the attendance at the Simulator/Advanced course, the training centre will
issue a new logbook and clearly mark this as part of the certificate renewal
process.
Refresher courses, even for those regularly operating DP systems, are
considered beneficial and the content of these should be tailored to the needs
of the individual, the company and the industry."
