The proposed Notifier NFS fire panel has been deemed acceptable by SPLNG for monitoring of the Administration, Warehouse, and Control Buildings. The Jetty, Customs, and Switchgear / Electrical buildings shall be monitored by the Det-Tronics system due to their proximity to the process areas. The necessary hardwired cross connections shall be provided to integrate the Det-Tronics and Notifier systems. A Det-Tronics S3 console shall act as the annunciating console for the combined building and process area fire and gas detection system. A hard-wired interface shall provide a general alarm and trouble from the Notifier NFS to the Det-Tronics controller.

B-1. Trend T-1012 is to implement the Fencing & Security System Enhancements as follows:

1) Move the fence across the road at the curve near the construction dock.

2) Move the interior fence from west of the Warehouse to between the Warehouse and Administration Building.

3) Move helipad slightly north east, within the area where soils were previously stabilized and north of future road that will align east-west with gate on eastern facility fence.

4) Delete east-west fence north of LNG storage area.

5) Relocation of north Process Gate operator and associated card readers to driveway north of Administration Building. Add intercom that annunciates in Guard House and Main Control Room. Gate operator shall be remotely controllable from both locations.

6) Delete South Process Gate operator and associated card readers.

7) Relocate Main Control Building turnstile and associated card readers to footbridge southwest of Administration Building. Add intercom that annunciates in Guard House and Main Control Room. Turnstile shall be remotely controllable from both locations.

8) Add a turnstile with card readers at both the East and West Jetties (between the platform and jetty access road).

Add intercoms that annunciate in Guard House and Main Control Room. Turnstiles shall be remotely controllable from both locations.

9) Add two (2) turnstiles with card readers at the road entrance to the tug berths.

Add intercoms that annunciate in Guard House and Main Control Room. Turnstiles shall be remotely controllable from both locations.

B-2. Trend T-1030 is to delete the fence intrusion system from Bechtel’s scope of work. This scope of work was defined under Bechtel Trend T-SP-049 dated April 4, 2004. This credit was reduced by fifty-eight hours for activities already performed for this scope of work.

C. Trend T-1005 is to install 7 piles, two foundations, 3 liquid sample probes, 2 gas sample probes for two future gas chromatograph shelter locations. The scope of work includes the piping related work for the installation/relocation of sample points and the necessary valve and / or probes on the sample connections to the process piping as to not require piping to be blown down in the future.

D. Trends T-0142 / T-1009 are for the supply and installation of double block and bleed valves and a flanged, removable spool piece required on all natural gas and nitrogen lines entering any maintainable vessel.
