FOB: Destination NET AMT Section C - Descriptions and Specifications STATEMENT OF WORK 1. Background/Definition: A. General The USNS ZEUS (T-ARC 7) cable repair ship was built by NASSCO under the 1984 rules for an unmanned/ACCU rated plant. The vessel is operated by the US Navy – Military Sealift Command (MSC). The vessel has a diesel electric plant with a centralized automation and propulsion system. The automation system and the propulsion SCR drives are obsolete and supportability is becoming an issue. Military Sealift Command intends to replace both the automation and propulsion systems with new technology. The intent of the replacement is to keep the same basic form, fit and function of the existing Automation and Propulsion Systems. The new system shall be supportable for a minimum of 12 years. This statement of work contains seven (7) appendices: A - Automation System Replacement B - Silicon Controlled Rectifier (SCR) Drives Replacement C - Government Furnished Information D - Generator Cylinder Temperature Thermocouples E - Independent Control and Monitoring Systems F - Existing Equipment Data G - Power Supply System These appendices are to be considered an integral part of this specification.

Automation System (see Appendix A) The replacement Automation System shall alarm, monitor and control all of the inputs and outputs (I/O) on the existing system as well as the additional points required by this specification, regulatory requirements and the contractors own requirements. The replacement system shall be designed to match the interfaces of the following existing systems/equipment; ? All bridge Ship Control Console (SCC) interfaces ? All Dynamic Positioning System (DPS) interfaces ? All Firemain Panel interfaces (SCC panel and panel outside the machinery space) ? All Engineer’s Extension Alarm Panel interfaces ? All existing inputs and outputs The vessel’s replacement automation system shall include the Alarm, Monitoring and Control System (AMCS) and the Propulsion Control System (PCS). The AMCS and PCS shall be independent of each other and each shall be redundant. The AMCS and PCS processors shall be communicated over redundant Ethernet communications loops. An example of the system architecture for the replacement automation system is shown in Figure 1. MSC will consider the contractor’s standard designs and other architectures as long as the reliability and redundancy are considered equivalent. The replacement automation system and equipment shall meet all of the environmental and redundancy requirements of the 2009 ABS and USCG rules. Figure 1 Example System Architecture 1.C.1 Alarm, Monitoring and Control System (AMCS) The AMCS shall have redundant processors that are arranged in a hot standby configuration. In the event of a failure of the on-line processor the standby processor shall automatically take over. Inputs and outputs (I/O) for the AMCS shall be via I/O racks located in the Main Control Console, on the EOS bulkhead, at each main generator, in the Propulsion Local Control Panel and other locations as required. Communications between the I/O racks and the processors shall be via redundant communications loops. 1.C.2 Propulsion Control System (PCS) The PCS shall have redundant processors that are arranged in a hot standby configuration. In the event of a failure of the on-line processor the standby processor shall automatically take over. Inputs and outputs (I/O) for the PCS shall be via I/O racks located in the Propulsion Local Control Panel, in the Main Control Console and in the SCR cubicles (if needed). Communications between the I/O racks and the processors shall be via redundant communications loops. 1.C.3 Operator Interfaces Operator interfaces to the automation system shall be via discrete pushbuttons, indicator lights, illuminated pushbuttons and other devices as described in this specification and through six (6) flat panel displays with keyboards and trackballs. Five (5) of the flat panel displays are to be located on the Main Control Console (MCC) and one in the Chief Engineer’s Office. The MCC units shall have full capability to alarm, monitor and control the equipment. The Chief Engineer’s unit shall have alarm and monitoring capability only, no control capability. All MCC flat panel displays shall be as large as possible (minimum 20”). The Chief Engineer’s display shall be a 17” flat panel display. All MCC keyboards and trackballs shall be drip proof. 1.C.4 Automation System Power Supply (see Appendix G) The existing automation and SCR power supply system shall be reused to the maximum extent possible. There is an existing 18kVA UPS with an automatic bus transfer switch (ABT) upstream. The ABT is fed from both a |
