Microprocessor-Based System Monitors/Controls Mooring Lines

—Literature Available A compact, microporcessor-based monitoring system that measures cable tension, line position and speed of submerged mooring lines is available from remote Systems Technology (RST), a subsidiary of Baldt Inc.

The electronic Load Monitoring/Line Payout System indicates values measured on a backlit LCD display and can interface with calculation equipment to control line position and speed. It can be used on ships, barges, drill ships and semisubmersibles, in conjunction with a winch or crane. In situations where line pull stress limits are about to be exceeded, the system can sound an alarm or automatically initiate equipment shutdown.

Examples of equipment affixed to mooring lines include anchors, electronic packages, remotely operated vehicles, and current, temperature and depth meters. System features include an alphanumeric display that guides the user through operating sequences.

The system incorporates 16K bytes of program memory and interfaces with the following inputs and outputs: 4 channels of analog input which can be converted to digital values with 12-bit (1 part in 4096) resolution; 4 input amplifiers for calibration of transducer signals; 8 digital inputs for special function switches and ON/ OFF sensors; 4 output relays; 2 analog output channels; 20 position sealed keyboard; and 2 line x 16 character backlit LCD display.

The input channels can be configured to accept load cells, pressure, angular position and linear position transducers; temperature and magnetic flux sensors, and pendulums. Custom configurations are also available to meet specific application requirements.
