Revalidation of Limited/Unlimited or Unclassed DP Certificates


To revalidate your DP Certificate in 2024, in addition to the 150 days of sea time or equivalent, you will also need to:



  • Complete the NI DP Refresher Course  


  • Be enrolled in a NI-approved Continuing Professional Development programme AND undertake the on-line examination. 


To ensure all applicants have enough time to meet the requirements, we will be introducing the changes gradually. Although your revalidation may not be due until 2024 or beyond, it is important you understand this requirement now. 





  • If you have between 30 -150 days of sea time - You must complete the NI DP Refresher Course


  • If you have less than 30 days of sea time - You must complete the NI DP Revalidation Course


Note: All DPOs whose certificates are due to expire from 1st January 2024 until 31st December 2028, and have been unable to complete the new requirements for revalidating their certificate, will be issued with a 12-month indemnity letter once their online application has been submitted/paid. The applicant must complete the new requirements of the CPD and/or courses and resubmit their application within a year of the issue date of the letter to be eligible to apply.



The indemnity letter is not to be used by the applicant to complete any of the sea time requirements for their application.
