COMPRESSED AIR 40 HYDRAULICS & PNEUMATICS April/May 2020 www.hpmag.co.uk ALS compressors.” ALS – or air lubrication system – is a method used to reduce the resistance between the ship’s hull and seawater by using air bubbles. The air bubble distribution across the hull surface reduces the resistance working on the ship’s hull, creating energy-saving effects. The seven LNG carriers in question will be equipped Hyundai Heavy Industries’ self-developed Hi-ALS air lubrication system. According to Hyundai Heavy Industries, its Hi-ALS system can cut fuel consumption by up to 8%. TMC’s marine compressed air systems for ALS will be coupled with the Hi-ALS system to generate the required stream of air bubbles that passes continuously beneath the ship’s surface, thereby reducing frictional resistance between the hull and the seawater and producing the desired energy-saving effect. www.tmc.no TMC Compressors of the Seas (TMC) has been awarded a contract by Hyundai Heavy Industries to deliver its air lubrication system compressors to seven LNG carriers the Korean shipbuilder is constructing for Capital Gas Corp. TMC has developed a range of marine compressors for use in combination with air lubrication systems (ALS) to help ships further reduce fuel consumption and emissions to air. Under the contract, TMC will supply three marine ALS compressors to each of the seven LNG carriers, in total 21 compressor units. TMC will also provide its ALS control system that is integrated in a specially designed control cabinet. TMC has not disclosed the value of the contract. The equipment will be manufactured in Norway and shipped to Hyundai Heavy Industries in Korea. Green commitment Hans Petter Tanum, TMC’s director of sales and business development, says: “During the past 15 years, we have more or less constantly tried to identify new ways of reducing energy consumption and the environmental footprint of our compressors. Identifying new usage areas for our compressors, such as ALS, is part of our commitment to making shipping greener. Landing such a significant contract with Hyundai Heavy Industries is a fantastic seal of approval for our new range of TMC secures ALS compressor contract for seven LNG newbuilds TMC’s ALS compressor. Chicago Pneumatic has introduced a new range of air motors to its portfolio. The comprehensive air motor range combines multiple configurations, a compact and well-balanced design and excellent performance in harsh environments, enabling OEM and machine builders to improve the efficiency of their systems. “We are excited to include air motors as part of our product portfolio for the first time,” says Damien Feller, global product marketing manager, spares & solutions, at Chicago Pneumatic. “This addition to our catalog is ideal for OEMs and machine builders looking for simple yet reliable power in applications including pipe processing, mixing, blending, filling, metering in food and chemical processing, and machine maintenance. The new range complements our existing range of pneumatic products and tools and reinforces our position as leaders in industrial pneumatic solutions, so customers can be assured they are receiving the highest quality product and support.” Versatility There are nine models of motors in the range, providing power from 0.16 kW (0.21HP) to 1.8 kW (2.45HP), maximum output torques of up to 299 Nm (221 ft.lbs) and speeds of up to 21,500 rpm. They are easy to install and use providing users with high versatility based on their needs. Power can be adjusted easily by regulating the air supply, pressure or throttling, and users have a choice of progressive or immediate start to best suit their application. The motors are efficient thanks to a lightweight and compact design. They feature internal planetary gears which contribute to a long, slim design, and the motors are up to six times smaller and lighter than electric motors of equivalent output power meaning OEMs can reduce the overall weight of their machines. Output inherently adjusts to match the applied load, which further enhances efficiency, and low friction blades, which are a lubrication-free design enable users to improve their sustainability. They are a cost-effective solution compared to other motor types, with low installation, operation and maintenance costs. www.cp.com New air motors from Chicago Pneumatic provide simple yet reliable power
