Changes made to LNG TF 11-01, the working document for today has been amended between LNG TF 10 teleconference on 3 July and today. The changes can be seen in the updated initial document, now shown as LNG TF-11-03.

Justifications were added at the bottom of the new document using other existing standards and regulations referenced on the subject of LNG tank valves. Mr. Dijkhof reviewed the language of the newest document (based on the draft submittal of the Netherlands) as well as the standards/regulations for CNG, LPG and hydrogen.

A service valve and manual valve is not intended to be put in series for redundancy purposes. A more complete description of the manual valve has been included indicating that it is only for servicing while the automatic valve is used for fuel shut-off purposes (other than servicing) when the ignition is off, for whatever reason.

Mr. Dijkhof explained that the RDW did not intend to have the automatic and manual valves in series. The important point was that in CNG, LPG and H2 the automatic valve should be on the tank. That is why it might make sense to explain in the definition the distinction between the purposes of the manual valve and automatic valve (service versus shut-off when the ignition is off, for any reason).

Mr. Ursan indicated that what the RDW wants make sense, and that the more complete clarification of the valve functions would be an improvement in the document.

Wording that includes the manual valve OR automatic valve is not what RDW wants. Mr. Dijkhof believes that the clarifying the purposes of the valves explains the intention of the components, which should avoid confusion.

Mr. Ursan added that this is the intention of the Australian standard as well, although the language is different.

The new language added in sections 8.13.1.2 and 18.13.1.3, ‘provisions on components fitted on the LNG Tank’ now includes the purposes of the valves. (for ‘service’ and for ‘fuel shutoff’).

Also the Australian/NZ standard, which agrees with our approach, will be added in the justification section of the proposed amendment document.

Mr. Murray (Chart) also suggested that we add for the manual valve ‘for fuel system maintenance’ to the explanation.

The team agrees that the new language will be satisfactory to the RDW. The new document will be sent to the LNG-TF for any comments. Mr. Dijkhof has had a discussion with RDW staff and they agree that, if the proposed amendment mandates an automatic valve mounted directly on the tank (regardless of what other clarifications might be added) then it is acceptable and Mr. Dijkhof should send the amendment to GRSG secretariat on Friday.

Mr. Dijkhof thanked the group for their cooperation and input. We will send the newest document to the LNG TF immediately and will consider any comments received before the close of business on 11 July 2013. Mr. Dijkhof will submit the final document on 12th July 2013 to the GRSG secretariat.
