Yes. The Nautical Institute now issues a validity date on all certificates. The certificate will be valid for a period of five years. At the end of the five years, you will need to revalidate this certificate again. Please ensure that during the five years, you are logging your DP time ready to use for revalidation. Please see the Offshore revalidation or Shuttle Tanker revalidation page on our website for more details. Frequently asked questions can be found here.
