Nautical Institute DP Revalidation: FAQ
- What is the Nautical Institute DP Revalidation (DP-REVALIDATION) certification?
- 5-yearly DP Operator revalidation by either 150+ days DP sea time, an approved DP simulator course, or an NI assessment. Category: DP.
- Who needs DP-REVALIDATION?
- DP-REVALIDATION applies to seafarers in roles defined under STCW. Recommended prerequisites: dp-advanced. Without DP-REVALIDATION, operators may decline to roster you for the relevant duties.
- How long does DP-REVALIDATION take?
- Typical course duration is 32 hours (4 working days at 8h/day). This is face-to-face or blended-learning time at an approved training centre; revalidation refresher courses are usually shorter. Plan against your sea leave window before booking.
- How much does DP-REVALIDATION cost?
- Typical cost is around US$2400 at an approved provider. Cost varies widely by country and training centre quality; many shipping companies cover the course fee as part of the contract. Check with your manning agent or fleet department before paying out of pocket.
- Where can I get DP-REVALIDATION?
- DP-REVALIDATION is delivered by approved training centres in most major maritime training countries. Use our /training-centres directory and the certifications-by-country filters to find an approved provider near you. The flag administration of your seaman's book may also publish a list of accepted providers.
- How long is DP-REVALIDATION valid?
- 5 years from issue, with a refresher required every 5 years. Plan your revalidation course before the expiry date; lapsed certificates may require re-sitting the full course rather than a refresher, and operators may refuse to extend a contract while a critical certificate is expired.
