Specialised Weapons & Material Handling

Today many shipboard systems have increased automation requiring digital controls, solid state relays in lieu of electromechanical relays, and invoke PLCs for increased service life, reliability, flexibility, and compatibility with newer technology. FEC has a solid background incorporating PLCs in weapons and material handling systems, particularly in the elevator and conveyor arena.

FEC furnished all fourteen shipsets of the T-AKE hangar door assemblies. These doors consisted of flight deck/cargo doors with stainless steel roller curtains as well as helicopter hangar door assemblies rated at 60 psf. FEC also produced the A-60 rated “Fire Doors” for the T-AKE class ships. The fire doors are electromechanically operated solid panels and are utilized to separate the helicopter hangar area from the interior cargo handling spaces. The doors are fabricated using steel plate with A-60 fire rated insulation applied between the vertical and horizontal door stiffeners. An expandable “fire seal” is present around the perimeter of each door to provide a seal with the adjoining bulkhead to prevent the passing of heat and smoke in the event of fire. These doors have been fully tested and certified to meet the A-60 fire door rating requirements.
