Morehead City, North Carolina - Cape Fear International, Inc. is proud to introduce a new solution for inlet and waterway maintenance, coastal protection and beach replenishment. CFI's SeaDozerTM offers a method to protect shores from storms and hurricanes through an effective and inexpensive approach. This technology has been tested and proven by the U.S. Army Corps of Engineers.

Many channels, waterways and harbors are subject to rapid localized sedimentation. Often this shoaling involves small quantities of sediment, but removal requires major financial outlays for traditional dredges and dredge mobilization costs. These disproportionate costs often dictate foregoing needed maintenance dredging and accepting a substandard channel for major portions of the year.

 SeaDozer fulfills the need for a highly mobile, specialized dredging capability to address these cases where material placement sites are reasonably close and sediment quantities are relatively insignificant compared to the costs of conventional mobilization and demobilization.

Cape Fear International has patented SeaDozer, a new dredge which specifically addresses this shortfall by converting the vortex discharge of multiple propulsion units and directing it to relocate the bottom material by directed water-injection.

SeaDozer can operate in seas up to six feet, even in surf zones, to direct material out of critical areas with negligible effect to marine life. Underwater conditions during SeaDozer operations resemble a normal storm surge event, with no long-term effect on biodiversity.

In addition, SeaDozer can also accomplish rapid, localized beach replenishment and protection tasks with its ability to create protective underwater sand berms near beach areas. It is especially suited for shallow and rough conditions where even smaller hopper or side-cast dredges cannot operate effectively or safely.

Beaches and coral reefs that have been clogged by fine silt as a result of previous conventional dredging, farm run-off or near-shore construction activity can be cleaned and revitalized using SeaDozer's outstanding hydrodynamic capabilities.

USACE Dredge Sandwick

 

SeaDozer utilizes directed hydraulic flow, a technique employed by the Portland District of the U.S. Army Corps of Engineers utilizing their bypass dredge "Sandwick". A review by the U.S. Army Corps of Engineers Waterways Experiment Station on agitation dredging methods concludes that directed  water flow is one of the methods that appears most technically feasible.

SeaDozer is being considered by the Corps of Engineers for participation in selected pilot research projects aimed at reducing the costs of underwater material management.

SeaDozer will be underway at approximately 2 knots during normal operations, dislodging and transporting bottom material at a controlled rate in the desired direction.

SeaDozer will also maintain position over an isolated sandbar, liquefying and transporting material to the desired location.

 SeaDozer Advantage

SeaDozer is "environmentally friendly". Its impact more closely resembles a normal storm surge event, short-lived with no long-term effect on biodiversity. Marine life is swept out of the way by SeaDozer's hydrodynamic flow, able to return later. 

 

SeaDozer is a platform hull with four thruster/propulsion units which creates a stable vessel capable of operating effectively in shallow, rough seas. (5’-30’) without the need for anchors or spuds

With a two man crew and the ability to operate independently SeaDozer reduces the mobilization and demobilization costs which often represent 40% of the cost of dredging projects.

SeaDozer costs less than half the cost of available dredges, that do not have SeaDozer’s capabilities.

With 2000 hp powering  four propellers, SeaDozer’s production rate3approaches 2000 cubic yards per hour.

SeaDozer's state-of-the-art computer controlled dynamic positioning and its ability to  travel at fifteen knots makes the periodic maintenance of wide spread shoals and sand bars along beaches, inland rivers, waterways, ocean inlets and harbors feasible.
