Aluminum Anode Sled

This pyramid aluminum anode is designed for replacing depleted anodes on mature offshore assets. It can be quickly installed by lowering it onto the sea floor. Compared to underwater welding or other methods of attachment, its speedy installation is incredibly cost-effective . Thus, our anode sled is ideal for anode retrofit projects of subsea equipment and platforms.
