At Thanes Marine we have developed this questionnaire which is based on ISO 10239, the current standard for marine gas systems.
This questionnaire can be used by Surveyors, Gas Engineers or Owners to create a report of the state of the LPG installation on a boat.
The certificate can also be used to report to a prospective buyer, an insurer or a marina.
This is currently a free single use service so please use it.
All you need to do is create an account.
