Dredging Research Program. Dredge Mooring Study, Recommended Design, Phase 2 Report
1992
Blair, Jerry A.
This report describes the design of a four-leg catenary anchor leg mooring and capsule buoy for the direct pump-out of Corps of Engineers hopper dredges. This is the second phase of a two-phase study. The campaign report (phase I - conceptual design) describes operational conditions and operational criteria and buoy dimensions (28 ft long by 11 ft 6 in. wide by 7 ft 6 in. high) . This report provides detailed information on: (a) structural calculations, (b) buoy stability, (c) piping system pressure loss analysis, (d) system time/resource analysis (during transport, assembly, and installation), and (e) an example bid proposal specification for procurement. The system time/resource analysis section describes the amount of dock space and staging area required (250 ft by 300 ft of dock space), crane requirements (a 50- to 60-ton crane), and time and personnel required for reach action. The report estimates the buoy could be assembled by five personnel and installed onsite by four personnel (including a diver) in 1 week or less (5 days minimum). With the addition of a second crane and second anchor handling vessel, the assembly and installation time could be reduced by 1 to 2 days. Direct pump-out Hopper dredges Single- point mooring buoy.
