Hull Closures/Doors

Along with shipboard deck machinery, Federal Equipment Company specializes in customized hull closures, specifically door and hatches, that come in a variety of shapes and sizes and applications. Since hull closures are critical to a ships survivability in maintaining compartmentation and watertight/weathertight integrity, FEC doors and hatches are designed, manufactured and tested to meet the most stringent requirements. As a leading hull closure supplier to the U.S. Navy and Coast Guard and their premier shipbuilders, FEC has a proven track record furnishing a multitude of doors that can be found on virtually every class of ship such as the LHA, LHD, LPD, LCS, T-AKE, MLP, NSC, and AOE class, just to name a few. Illustrated below are some of FEC’s featured doors.




Littoral Combat Ships (LCS) - Roller Curtain Doors


Similar to the NSC Class doors, FEC designed and manufactured the helicopter hangar doors for the LCS Independence variant built by Austal USA. These doors are also manufactured from aluminum and rated for 40 psf wind load. These port and starboard roller curtain door assemblies meet all the LCS specification requirements including shock and EMI qualifications.


Currently FEC is engaged with Austal USA in an on-going effort to design a new light weight stern door for the LCS Independence Class. Using an innovative door slat design with a combination of composite and aluminum materials, FEC and Austal are hopeful to initiate manufacturing soon with a target installation in 2017.




"Deepwater" National Security Cutters (NSC) - Roller Curtain Doors


The NSC Class ships also prominently display FEC helicopter hangar doors on the flight deck. Designed and built for Huntington Ingalls Industries, this heavy duty helicopter hangar door system is an all-aluminum construction rated to sustain a 40 psf wind loading.


T-AKE Class Ships - Roller Curtain Doors


Designed and manufactured for General Dynamics NASSCO, 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 as well. 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.
