The LSD-41/49 Class Smart Gator Enabling Technologies (Enabling Technologies) upgrade replaces specified existing machinery control and monitoring systems units/consoles plus the addition of specific equipment. Overcoming component obsolescence, reducing equipment support costs, and reducing workload are key objectives in the Navy旧 upgrade plan.
Reducing the number of different assembly types and total number of assemblies required are considered key factors in meeting this objective. The descriptions of Enabling Technologies follows:
The Local Area Network (LAN) is installed as a ship wide fiber optic communications network used to interface with the Enabling Technology multi-functional workstations (MFWS), view ports and interface input/output (I/O) devices. The LAN will be installed with expansion in mind to support future additional users/technologies. The new Machinery Control System, Damage Control Quarters/Ballast Control System, Integrated Bridge System, and Integrated Condition Assessment System ships Enabling Technology network will utilize this LAN.
The Machinery Control System (MCS) installation replaces specified existing machinery control and monitoring systems units/consoles associated with both the Main Propulsion (MP) and Electric Plant (EP) control systems. The MCS consists of software-based control system utilizing MFWS and Data Acquisition Units (DAUs) controlling the main propulsion, electric plant and selected auxiliary systems.
The Damage Control Quarters (DCQ)/Ballast Control System (BCS) consists of several software-based LAN-resident subsystems including, but not limited to: Damage Control sensor/systems integration; firemain and ventilation/control and display, ballast system control and display. The system will replace the individual control allowing creation of a "central control station" (CCS) in what is currently Damage Control Central (DCC). The Government will provide the DCQ/BCS software, Programmable Logic Controller (PLC) software and Interface Control Documents (ICDs) for DCQ/BCS.
The Integrated Bridge System (IBS) converts legacy navigational information sources, such as; GPS, Speed Log, Gyro, Wind bird and depth sounder, into digital data formats and provides them throughout the ship via the LAN. The IBS contains a computer program that uses the navigational data and interfaces with MCS and the steering gear to provide steering and propulsion control both on the bridge and in CIC. The capabilities of the IBS shall include the traditional non-follow-up control, hand electric, auto pilot and track steering.
The Integrated Condition Assessment System (ICAS) software products provide a computerized engineering tool to implement Condition Based Maintenance (CBM) and equipment availability management. Inputs to ICAS consist of both manually collected and on-line sensor data. ICAS shares on-line sensors with the MCS. New ICAS specific on-line sensors shall also be installed by the contractor.
ICAS continuously assesses machinery performance conditions and transmits the information over the LAN to be viewed at the applicable MFWS(s). The Government will provide HMI software, PLC software, and ICDs for ICAS.
The Wireless Internal Communications System (WICS) is an internal wireless communications system installed to provide internal communications for command and control of combat systems, damage control, security, beach guard, sea and anchor detail, administration, and integrated team training. The system shall consist of an antenna/transmission/receiving system, portable radio units, and charging stations.
The Smart Gator Enabling Technology upgrade provides for electronic technology modernization by replacing the existing rigid HMI console designs with Software Alterable Graphic Interfaced multi-functional workstations. |
