control system layout and design.  The enclosures are usually mounted on
leveling jacks or stands, or they may be mounted on a field-constructed
Where ISO units cannot be used such as 10 foot wide units, built-in
tension members in the wall and built-in spreader bars in the roof should be
provided so roof line hoist points can be used at the quarter points of the
container. Removable end panels, some with personnel doors, are often times
provided to simplify the installation and removal of equipment.  Flexible
(accordion like) weather covers and demountable walkways are used to connect
the transportable either to a building or to other transportables when
applicable.  When stair access is provided allow sufficient platform space at
the top for door swing and so it will not be necessary to back down the stairs
to open the door.  Railings should meet OSHA 2201, Safety Standards for
General Industry.  Transportable/non-relocatable. With this type of enclosure, there
is little or no emphasis on relocatability.  Shipment may include any number
of packages, which are field-assembled and installed.  Factory fabrication and
pre-assembly are usually limited to providing several large portions of the
enclosure or complex, along with some portions of the power wiring, plumbing,
and air conditioning.  The enclosures are usually mounted on field-supplied
foundations or supports.  Sub-categories.  Various sub-categories of transportables include
trailers, semi-trailers, vans, milvans, containers, and shelters.  These are
generally in the tactical or relocatable category, but, in certain
applications, could be classified as non-relocatable. Containers are ISO
standard-sized units. Two are of particular interest for housing and
transporting Naval electronic equipment; both are 8 feet (2.4 m) wide by 8.5
feet (2.6 m) high, and are either 20 feet (6.1 m) or 40 feet (12.2 m) in
length. These units are designed for a gross weight of 44,800 pounds (20 317
kg) and 67,200 pounds (30,475 kg), respectively, and are provided with rugged
corner fittings for hoisting, stacking, and shipping.  Milvans (the Army
equivalent of ISO containers) are only available in the 20-foot (6.1 m)
version. Shelters are tactical units and rarely exceed 7 feet (2.1 m) wide by
7 feet (2.1 m) high by 12 feet (3.7 m) long. Trailer, semi-trailer, and van
dimensions depend on the particular vehicle selected for use.  For further
information, refer to NAVELEX 0101,110, Installation Standards and Practices.

Architectural and Structural  Structural Requirements. Transportable facilities shall be
designed to withstand equipment weights and other in-service loads, plus any
load resulting from storage, handling, and transportation. Where possible,
the design should incorporate the longeron/stressed skin (semi-monocoque)
concept.  This permits maximum interior space with respect to outside
dimensions, but limits the size and location of openings and requires careful
design of framing around opening.  (In extreme cases, an entire wall or end
may be open where one container is coupled to another, and it may be necessary
to use shipping panels that provide structural support at the openings when
the containers are in transit.)
