The Italian and, extra lately, US Navy have each commissioned FREMM (Frégates Européennes Multi-Missions) and FFG62 Constellation Class Guided Missile Frigates respectively, constructed by a significant Italian ship builder at its Italian and US shipyards. The aero derived gasoline generators powering these ships, and configured for marine functions might be protected by Parker altair® Neptune filtration techniques. The main Parker altair® Neptune filtration techniques are designed to make sure a clear, dependable provide of air to the gasoline turbine inlet. Downstream Salt focus is 0.0025ppm v NGTE 30 knot aerosol. Equal to 99.93% salt removing effectivity, important for offshore operation. They’re additionally ultra-compact and lightweight, making them superb to be used on such vessels. Critically, the system contains a three-stage resolution, together with marine vane separators and coalescer/filters, which offers the excessive effectivity and efficiency required to be used in navy vessels.

As a part of a long-term contract, Parker has supported the multi-FREMM improvement program and has already delivered 10 FREMM ship units for the Italian Navy. This engagement has been prolonged with an order for a further two, for supply in 2022. The current order for the FFG62 frigates for the US Navy was acquired final yr and in the end will lengthen to 10 ship units over the following six years, with the primary deliberate for supply subsequent yr. The FFG62 is a part of the US Navy Small Floor Combatant (SCC) program and has a wider and extra elongated hull relative to the dad or mum design of the FREMM. The procurement of those vessels helps the Navy’s force-level objective of a 52 SCC pressure inside the present 355 whole ship plan. Frigates are designed for velocity and manoeuvrability. This makes the supply of GT spec compliant air to the propulsion techniques (gasoline turbine) important to the mission.


Neptune filtration system

Gerald Woodward, Division Gross sales & Advertising and marketing Supervisor at Parker, stated: “We’re delighted to be supplying additional ship units for the Italian vessels and with the brand new contract for the US Navy. These techniques are properly confirmed and their gentle, compact type means they are perfect for a variety of vessels. Their superior design ensures dependable, strong operation and fewer filter changeouts, making them superb to be used in a marine surroundings. The Neptune system is confirmed to offer distinctive salt removing. Its use in these naval functions displays the arrogance shipbuilders and turbine OEMs have in its design and operation.”

A well-designed air consumption system not solely delivers clear air but in addition facilitates upkeep actions comparable to filter cleansing or changeout and drainage inspections. Anti-ice techniques and automated by-pass doorways are additionally a part of the scope. The Neptune filter system is appropriate for gasoline generators and, on the FFG62 vessels, additionally the diesel turbines. Through the use of these state-of-the-art filters, each navies might be assured of dependable operation and, by defending the effectivity of the generators. Turbine internals are simply broken by the corrosive nature of salt. The primary stage of the Neptune system removes bulk water from rain, sea spray and aerosols. Within the second stage, a coalescer removes mud and stable contaminants in addition to tremendous aerosols by coalescing them into bigger droplets. The third stage makes use of a vane separator to take away concentrated saline options which have handed by way of the primary levels.
