Review of Coastal Navigation Asset Management Efforts within the Coastal Inlets Research Program (CIRP). Part 2. The Channel Portfolio Tool.

摘要

This Coastal and Hydraulics Engineering Technical Note (CHETN) summarizes research efforts that have taken place since the 2008 fiscal year (FY) within the Coastal Inlets Research Program (CIRP) concerning asset management of coastal navigation channels. Specifically, the details concerning the conceptual basis and application of the Channel Portfolio Tool (CPT) are described. The CIRP work unit responsible for all of the efforts described herein is referred to as Coastal Navigation Portfolio Management (CNPM). In response to a direct request from USACE-HQ, beginning in July of 2008 the CIRP started development of the Channel Portfolio Tool (CPT). This web-based software uses the proprietary, dock-level tonnage database maintained by the Waterborne Commerce Statistics Center (WCSC), part of the Corps Institute for Water Resources (IWR) Navigation Data Center (NDC), for determining the extent to which dredged channel depths are utilized by commercial shipping. CPT provides an objective, consistent basis by which channels may be compared quickly to others for prioritization of Operation & Maintenance (O&M) funding, thereby providing improved justification for annual O&M dredging budget items. The preliminary, proof-of-concept version of CPT received positive feedback in a briefing to examiners from the Office of Management and Budget (OMB) prior to the end of FY08. These same examiners had indicated previously to USACE-HQ personnel that improved justification such as that provided by CPT is a required precondition for increased outlays from the Harbor Maintenance Trust Fund (HMTF), which carries a net balance of several billion dollars due to annual revenues exceeding outlays (GAO, 2008).
