Application for a certificate of survey and/or load line certificate for a domestic commercial vessel (form 521)


Overview

You can use this form to:

  • apply for a new certificate of survey, load line certificate, or both
  • renew an existing certificate of survey, load line certificate, or both
  • apply to alter or modify the vessel’s operations
  • apply to alter or modify the vessel’s structure, arrangements, material or scantlings
  • request changes to an existing certificate, including:
    • removing or changing a condition
    • changing service categories or capacity
    • updating engine details
    • changing the vessel name
    • updating the current certificate holder’s details (for example, a change of name).

You can’t change the certificate holder using this form. The new holder must complete a separate Application for change of certificate (or approval) holder for a vessel permission (form 1780).

We can’t assess your application until we receive the vessel survey reports.

You’ll receive survey codes after you apply. Give them to your surveyor and ask them to submit their reports as soon as possible.
