Sternmax 20

The groundbreaking Sternmax is a high capacity advancing Arctic skimmer designed to separate oil from the drifting ice with a high recovery rate of 100 m³/h. The 20 brush wheel skimmer system has two oil transfer GTA 50 pumps and an ice and oil separating grate that collects oil with excellent ice handling capabilities in harsh Arctic climatic conditions. 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 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 50 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. The Sternmax is designed and certified in accordance with DNV 22.2 Lifting Appliances and it is Ex-Zone 1.
