2003 level voting
I need to provide 2003 level voting on a vessel for SIL 1 shutdown. I only have two tappings (upper and lower) on the vessel.
Option 1: Provide a cross pipe with flanged tappings for remote dp seal transmitters on the upper and lower tappings.
Option 2: Provide a stand pipe. Weld 3 flanged tappings for the upper tapping and also for the lower tapping.
Please advise which option is best for the 2003 voting requirement.
