The MATCOR Sea-Bottom Anode is a factory-built marine anode sled for impressed current cathodic protection of docks, piers, pilings, and underwater structures. Weighing 900 to 5,000 pounds with concrete end weights, it is lowered to the sea or river floor with no field assembly required.
MATCOR’s Sea-Bottom Anode is complete and ready to install, including*:

Sea-Bottom Anodes can be designed and manufactured with almost any current output and life required. Contact MATCOR with specific current and life requirements and our expert corrosion engineers will design the right anode for virtually any marine cathodic protection application anywhere in the world. The physical size of the Sea-Bottom will vary with the current output and weight requirements. Areas of high water currents may require heavier assemblies. There are no depth limitations for the MATCOR Sea- Bottom Anode.
The method of installation will vary with each project and the size of the Sea-Bottom Anode. The assembly is moved with lifting lugs that are secured in the concrete end weights, or by lifting with slings through the bottom supports. The anode sleds are set on the sea floor or river bottom and the protective cable housing with cable, is run to the termination point. Any length of cable and housing can be attached to the anode assembly in the MATCOR factory. The heavy wood skid is not removed from the anode assembly when the Sea-Bottom Anode is installed. In cases where there are high water currents, weights can be placed over the cable housing to prevent movement of the cable. MATCOR manufactures ring concrete weights for this purpose. The installation of an entire system can be done very quickly. MATCOR has installed ten Sea-Bottom Anode sleds to protect a thousand-foot long dock in a single day.
