Know—and Compensate
for—All the Details

  • The tension of every deployed mooring line
  • Sea and weather conditions
  • Ship movement
Crew can also define the optimum line deployment per weather conditions. Or use Mooring Master's flexible reporting to see the big picture of mooring history over changing ship locations, seasons and loads.

The Need
Keeping a large vessel securely moored to terminals that experience extreme wind and tidal conditions is tricky and often dangerous.

Human error in judging and correcting mooring tensions endangers life, the environment and assets. Just "eyeballing it" risks overloading a line, a chain reaction of broken lines, resultant tragedy and the consequences of legal and public relations disasters.

Mooring Master—your science-based solution—demonstrates a firm and responsible corporate policy. Far more important, it curtails mooring problems at their source: unbalanced mooring line tensions.

How Mooring Master Works

  • Waterproof strain gauges (load cells) in every mooring hook electronically monitor tension in real time.
  • Meteorological sensors measure direction and magnitude of winds, currents, and the height of tides.
  • Ship movement sensors are a valuable backup for line tension monitors.
  • Hard-wired connections transmit tension, weather and ship movement data to the command unit in the control room.
  • A waterproof radio link system is available if a direct connection between the dock and the ship is not available.
  • Signal conditioners, a high-speed analog-to-digital (A/D) converter and special software prepare the data for display.
  • Crew graphically see each line's tension.
  • Unmistakable audio and visual alarms go off when any line approaches its rated load limit.
  • Crew correct each mooring line by the indicated amount—scientifically—not based on "feel" or the uncertainty of human perceptions, which could be suspect during inclement weather.
  • The system records the tension history of each line. The performance over several hours of any line or lines can be reviewed at any time.
  • Complete historical data—individual moment-by-moment line tensions, sea and weather conditions, and ship movement—are stored on an optical disk. Reports are easy to define and generate.
