1. If multiple, how many mobilizations are expected/required?

A minimum of two mobilizations will be required for these inspections.

4. Where is the fuel from Tanks 310, 311 and 211 being transferred into?

1. Tank 310 and 311 are approximately 100 feet apart. One of these tanks will have to be transferred into the other. Only two DS2 Tanks we have.

5. The Performance Work Statement references API 653 inspections and wiper seal replacement, but it’s not clear if contractors are also responsible for tank cleaning, fuel transfer, or mechanical services as part of this effort. Could you confirm if those services are included in scope, or if this requirement is limited strictly to inspection and seal replacement?

1. The contractor shall provide all personnel, equipment, supplies, facilities, transportation, tools, materials, supervision, and other items. The contractor shall also provide non-personnel services necessary to, execute the fuel removal, transfer or dispose of remaining fuel, clean the tank, replace wiper seals, and perform an AST Internal inspection on the tank(s), as applicable, at the location and for the tanks specified in Attachment B, as defined in this Performance Work Statement (PWS), except for those items specified as government furnished property and services.
