Call me if you have any questions or comments. Thanks, Eric Gillaspie 713-345-7667 Enron Building 3886 Chris Sonneborn 08/08/2000 02:32 PM To: Eric Gillaspie/HOU/ECT@ECT cc: Lal Echterhoff/HOU/ECT@ECT, Audrey Pullen/HOU/ECT@ECT, Gregory Lind/HOU/ECT@ECT Subject: Scope of work for Lost Creek SCADA installation Eric, this is a copy of the scope of work that I forwarded to Pat Flavin. It will need some clean-up to put it into the contract, but this should give you a flavor of what I am working toward. Thanks, Chris Sonneborn (713) 853-6530 - phone ============================================================================== ==== -------------------------------------------------------- cut here ---------------------------------------------------------------------- ============================================================================== ==== Timeline: Purge and pack pipeline 8/15/2000 First flow to CIG/WIC 8/19/2000 SCADA: 6 total meter sites SCADA Software versions: Enron Modbus CM1 95Q013 Ver 2.20c Daniels GC Comm2 95Q013 Ver 2.20c Enron EFM 95Q13 Rev 2.20f 8/99 At North end of pipeline (Lysite/Lost Cabin production office): There are three meter stations at the north end of the Lost Creek pipeline. They are the Fred Novotny, Keith Baker, and the Madden West meters. Each of these is a Fisher ROC 360 which needs to be set up with an MDS 9810 radio and a yaggi antenna. They will be polled using a master radio to be located at the Burlington Resources Lysite office nearby. This master radio's antenna will be mounted on a shared tower with the existing BR master radio system for the Madden Field area. The Lost Creek radio will operate on a different hopping frequency. Poll requests will be sent from Houston via VSAT and/or analog phone. A phone modem and a VSAT are to be installed at BR's Lysite production office and connected to the master radio through a PanelTec device. The VSAT should have the master port. Each of the RTU's is installed in a portable building, along with a chromatograph and other equipment. 110/220V power should already be available at each of the sites. At Sand Draw: A small meter (7 mmscf/d) will be located at Sand Draw, WY. This is another Fisher ROC 360. We would like to install a cell-phone modem for this device, as it will be polled infrequently, and is not of a critical nature. Again, power should already be available onsite. Lost Creek does not require analog dial-around capabilities at this meter. At South end of line (Wamsutter Plant): There are two meter stations, a plant, and a compressor that must be monitored here. To do this, we have two Fisher ROC 360's and a Rosemount Delta V. One Fisher ROC and the Delta V are installed at the Lost Creek Wamsutter plant site. The other RTU will be installed at the CIG/WIC interconnect site approximately 3000 (?) feet away. This remote RTU's data will be collected using an MDS 9810 radio system and yaggi antenna back to the Lost Creek plant site, where a master radio with a 360 degree antenna is to be installed. All three devices will be polled from Houston via either VSAT, 56K dedicated line, or standard phone system. The current debate over the VSAT versus the 56K line will be decided shortly, based on decisions by Enron IT security. Greg Lind should have more details soon. Again, we would like to install a PanelTec to provide dial-around capabilities should we have problems with the VSAT/56K line. The RTU for the CIG/WIC interconnect is currently in a chromatograph building at our staging area, and is programmed to handle flow through an orifice tube meter. The CIG and WIC meters are ultrasonics. This will require a reprogramming of the RTU. Is this something that can be done by HMS, or should I simply order a brand new RTU for the CIG/WIC interconnect and have it built correctly from scratch? Whether I use the one we already own, or order a new one, I will have to have RTUs for both the CIG/WIC interconnect as well as the chromatograph building I am talking about raiding. Thoughts? Either way, I believe this is a tight, if not downright impossible, timeline to meet for this particular interconnect point in terms of SCADA telemetry. Please correct me if I am wrong. Finally, we are working on the required legal documentation to allow Lost Creek personnel and contractors access to the CIG/WIC meter site to perform the installation. Equipment: Enron (Mike Moore) will place the orders for the VSATS and phone lines. Pat, I believe that you know how this works normally, with the breakout between Hughes and commisioning the VSAT and HMS and connecting the RTU and VSAT. (<--- This piece is currently on hold, as we are looking at the possibility of using a 56K line at Wamsutter and CDPD at the Lysite production office) Enron will provide the MDS 9810 radios and masters. Enron will provide antennas for the MDS 9810 radios at the RTU's, the Lysite production office, and at the Wamsutter plant site. Enron will provide the cell-phone modem and cell service for the Sand Draw meter site. Enron will provide both of the PanelTecs. Standard phone modems are already installed on all of the Fisher ROCs. One of these should be used at the Lysite office for dial-around capabilities. Another one should be used at the Wamsutter plant to provide dial-around capabilites. Installation: HMS will install and test all radio systems, including cabling, and the antennas at the Wamsutter and Lysite production office sites. HMS will perform final connections between VSATS and PanelTecs and test communications throughput. (if necessary) HMS will perform final connections between 56K line and PanelTecs and test communications throughput. (if necessary) HMS will install and test PanelTecs and correctly connect with analog modems, installed phone lines, and with the RTU's and the Delta V at both Wamsutter and the Lysite production office, as appropriate. HMS will install and test the cellular modem at Sand Draw. Best regards, Chris Sonneborn ENA Facility Planning
