MOBILITY
Goal M2: Maximize vessel mobility within ports and waterways.
FY99 Target: Maintain navigation aid availability at 99.7%.
Measure: Aid station days - discrepancy days/aid station days.
Measurement Issues: Interim measure - outcome measure to be developed.
Aid availability is a measure of the maintenance of established aids to
navigation. It measures program effort, reliability of equipment, and
personnel performance. This measure tends to overstate the discrepancy
time of the aids to navigation system: a single aid outage usually does
not degrade a waterway's entire aid system and vessels are still able to
transit normally. Complete system outages are rare, and usually result
from severe weather incidents such as hurricanes. While aid availability
is not a true outcome measure, it does bear on the level of mobility
through navigable waterways. Future measures may center more directly on
movement of commerce, or accident prevention. Confidence in measure is
moderate.
Causal Factors to be Addressed:
Aid to navigation outage or out of position.
Vessel allisions with aids.
Poor channel markings.
Obstruction in waterway.
Strategies to Achieve Target:
Ongoing Strategies:
Coordinate with other agencies and industry groups such as the
Interagency Committee for Waterways Management to encourage joint
problem solving.
Use research and development to improve waterways management, including
the computerized Waterways Evaluation Tool (WET) and other projects for
establishing the appropriate mix of navigation systems.
Establish improved navigation marks for mobility and safety in locations
of need.
Develop the annual Federal Radionavigation Plan for the effective
management of all federal radiaonavigation systems.
New Strategies:
Commence projects to install, replace, and realign navigation aids in
coordination with Corps of Engineers channel dredging projects.
Highlights: Chesapeake Bay, and the Houston Ship Channel.
Pursue regulatory activity to improve the aids to navigation system by
consolidating and eliminating differences between the Uniform State
Waterway Marking System and the U.S. Aids to Navigation System.
Efficiency Strategies:
Replace the aging buoy tender fleet with new vessels, providing
essential navigation services with less resources by leveraging
technology. Buoy tenders maintain aid to navigation infrastructure
which minimizes accidents such as collisions and groundings.
