Sternmax

The groundbreaking, patented, Sternmax products are high-capacity advancing Arctic skimmers designed to separate oil from the drifting ice with a high recovery rate. The brush wheel skimmer system has two oil transfer GTA pumps and an ice and oil separating grate that collects oil with excellent ice handling capabilities in harsh Arctic climatic conditions.

“The Sternmax is a uniquely design and patented specialized oil recovery system that is firmly mounted on the stern of cold water traveling vessels, especially in arctic conditions with ice. It can press through ice and penetrate into the oil trapped underneath to free it for highly effective recovery”

How it works

As the vessel with icebreaking capabilities crushes the ice, the Sternmax is deployed from the rear of the vessel. The isolation grate pushes the large pieces of drifting crushed ice under the water, separating the oil and water from the ice. The grate can be lifted and tilted to remove ice and debris. The oil is collected by the brush skimmer that separates the oil from the water and transfers the oil into a hopper equipped with two GTA pumps. The Sternmax is supported by an A-frame that deploys the skimmer off the stern of the vessel from its storage cradle. It is a robust and durable vessel mounted, hydraulically driven system that utilizes Lamor’s proven technology to enable successful Arctic oil spill response operations.
