Our Multi-Purpose Dredger Designed as an Amphibious and built-in Istanbul. The Crocodile is suitable for a wide range of works in all types of bodies of water.
The Crocodile, Multi-Purpose Dredger is versatile on the water, makes it suitable for uses ranging from heavy work to fast emergency response. Its powerful engine, propulsion system and pumps, superior mobility, and sophisticated positioning equipment place it in a class by itself. Another important environmental feature of the Multi-Purpose Dredger is its ability to operate with low noise levels. It is equipped with a supercritical silencer that reduces noise to remarkably low levels.
Cleaning and restoring contaminated rivers and canals and other waterways / Reconstruction of shorelines / Creating wildlife habitats / Controlling vegetation / Installing water pipes, pipelines and submarine cables / Flood Control, Installing water pipes, pipelines and submarine cables with the Multi-Purpose Dredger’s technology is possible to drive piles from the water. That protects the shores and enables pile driving at a considerable distance from the coast. The Crocodile Multi-Purpose Dredger moves independently in water with its propulsion system and excavator assembly. Crocodile Multi-Purpose Dredger anchors with its spuds and does not need steel cables for dredging, which may disturb passing water traffic.
The Amphibious machine arrives as a complete unit on a truck or cruises there by itself on water. After coming to the site on a trailer, there is no need for costly crane assistance because the machine is Amphibious simply “walks” in and out of the water without any outside assistance, and also there is no drafting limit for the operations because she is Amphibious.
The Crocodile Multi-Purpose Dredger can remove floating or rooted vegetation, harmful stones, and trash from the bottom via using the rake.
Multi-Purpose Dredger can pump the soil through a pipeline to a discharge area located up to 1 km away. In this process, the soil is mixed with large amounts of water, 80-90 % of the total volume.
The Crocodile Multi-Purpose Dredger’s independent dredging movements and anchoring are based on hydraulic stabilizers. 2 rear stabilizers, equipped with hydraulically tilting cylinders spuds. Depth control through hydraulic two front stabilizers with detachable floats and removable spuds.
International Maritime Organization announcing a strategy to reduce greenhouse gas (GHG) emissions to zero by the end of this century, marine environmental regulations have been tightened worldwide, and the implementation of emission control areas has begun to affect vessel operations. Mavi Deniz has successfully started new technologies for emission control regulations by developing dual-fuel solutions and cleaner green power technologies. Mavi Deniz’s Green Power Options; Solar Energy System, Battery Power System, Hydrogen Fuel Cell System, LPG System can fully integrate to Multi-Purpose Dredger + Amphibious including deck equipment and propulsion system.
Multi-Purpose Dredger + Amphibious Green Power Options
- Powered by Solar Energy System
- Powered by Battery Power System
- Powered by Hydrogen Fuel Cell System
- Powered by LPG System
- Dredging in places where it is difficult or impossible to work with other machinery
( lakes | rivers | wetlands | shallow waters | harbors | canals | shorelines | industrial pools | under bridges | in tunnels, etc. )
- Where unique/versatile dredger is needed, which can both pump and excavate
- Where it is not feasible to mobilize several one-purpose machines
( cutter suction dredger | backhoe dredger | excavator | tugboat | assembly cranes or assisting vessels for anchorage to the site )
- Dredging in places where there is a water traffic jam
- Where pipelines/submarine cables/ pile driving in water or on the shoreline is needed
- Where vegetation do not permit conventional dredger
- Where floating or rooted vegetation has to be removed/controlled from the bottom
- Where environmental dredging required
- Where Amphibious Dredger required
The Crocodile, Multi-Purpose Dredger’s propulsion system is designed to provide maximum power with minimal disruption. The crocodile can sail 4 to 8 knots. The propeller can be raised in shallow waters to protect aquatic vegetation and avoid disturbing riverbed sediment. Environmental dredging in the tropical and arctic climate.
The Crocodile, Multi-Purpose Dredger’s cab meets the highest comfort and ergonomic standards with excellent visibility. The pilot controls all hydraulic functions from the cabin. Amphibious Dredger is equipped with fully adjustable deluxe seats, easy to reach controls, side windows that can be opened, and a range of standard and optional accessories like sunroof hatch, radio system, and gauging for hydraulics/engine.
The Crocodile Multi-Purpose Dredger Equipped with a light, compact, low-pollution Cummins / Caterpillar / Volvo / Perkins vs. engine. The Amphibious Dredger excavator has the power to spare ( 260 to 700 hp – standard model: 260 hp).
Crocodile 1000 has a One-piece body divided into 7 watertight compartments for protection. Crocodile 1400 has a One-piece body divided into 9 watertight compartments for protection. Crocodile 1500 has a One-piece body divided into 13 watertight compartments for protection. Corrosion-resistant painting system for minimum 3 years guarantee. Protective skid bars on the bottom. Slip-Safe deck. Handrails.
Maximum bucket reach: 5.3 m to 12 m through 180º Maximum depth: 12 m
Breakout force (from bucket cyl.): 77 kN ( depends on selected option )
Digging force (from bucket cyl.): 40 kN ( depends on selected option )
Lifting capacity at max. Reach: 16 kN ( depends on selected option )
Several tools are available for backhoe dredging; a 400 lt bucket with teeth for standard work, an 800 lt bucket for bigger sites, and a clamshell bucket for environmental dredging. With the bucket of Amphibious Dredger, the dredged material can be deposited on barges or, in narrow channels, directly on the shore. Stone and trash removal can be done with the backhoe bucket, clamshell bucket. Larger stones can be moved to the coast, deeper into the water, buried, or they can, for example, be used to make a breakwater.
