Coastal Systems provided engineering services for the design/build construction of 10 acres of artificial reefs offshore of Dania and Hollywood beaches in Broward County. The mitigation was required for hard-bottom impacts from the planned Segment III (south of Port Everglades) beach restoration. The project consisted of placing 66,000 tons of limerock boulders utilizing a crane barge outfitted with precise positioning equipment. The boulders were transported using barges from quarries in Freeport on Grand Bahama Island. The crane barge was anchored in 15 - 20 feet of water approximately 500' off of the beach.

Coastal Systems provided an engineered approach to the construction with the following services:

• Coastal engineering wave statistical analysis to determine optimum construction schedule for favorable weather conditions
• Marine resource surveys to map hard-bottom limits utilizing towed underwater video
• Preparation of construction plans with reef mapping data and LADS data to modify environmental permits and use during construction operations.
• Mooring analysis design for temporary single-point mooring of supply barges
• Design/layout of pile anchor system for crane barge with supply barge in nearshore zone, adjacent to reefs
• Specification of high strength floating line for 4-point mooring of crane barge
• Design of barge loading ramps at quarry site
• Crane and barge marine positioning using DGPS
• Vessel tracking system
• Site engineering support
• Web-based project management
• As-built hydrographic surveys
• Construction management and automated quality control

Construction was completed between May and September of 2003, on schedule.

We constructed a complete offshore mooring system for Royal Caribbean in Labadee, Haiti.
