Larry,
The approach speed indicator you refer to that is currently used is not intrinsically safe and should not be approved for use by the FERC or USCG. The system we are recommending is similar to the one being used in India and other ports and is an integrated system. The additional cost of including the approach speed indicator with the tension monitoring and quick release is minimal compared to an incident. Larry Snyder and Tony Galt can give you more information on the need for this and the cost effectiveness.

Approach velocity metering is currently hand held and portable and will remain so. ?No permanent equipment is planned for installation. ?The purpose of the equipment is to measure the ship's approach velocity as it is nearing the mooring position. ?The velocity should not exceed 6 inches per second as it contacts the breasting dolphins. ?If the ship were to impact the dock at a greater velocity, then a subsequent inspection should be performed to ascertain whether or not damage to pier pilings had occurred. The metered mooring hooks have been recommended but not specified nor procured. ?The metered hooks would allow close monitoring of ship's forces on the dock during unloading and the data would allow for the ship to adjust forces on the dock, and this controlling the ship's position, by precise application/use of ballast and intermediate adjustment of mooring lines. This feature, by providing precise information on the forces (and motion) of the ship relative to the dock would allow for greater precision in positioning of the ship at the optimum vertical and horizontal position relative to the unloading arms and avoidance of undue forces on the unloading arms. This feature would reduce likelyhood of perc valves discharging and disconnecting of the ship during unloading. ?In summary, it's an information system that provides for a higher level of control of the unloading process.
