ship erection process deck plates are often distorted due to
welding, fitting practices, penetrations, inserts, and rolled-in
stresses at the mill.
Military Specification 1689 identifies the fairness requirements
of the different parts of the ship.
fairness is primary in these requirements because: a)
unfairness of the deck creates a corrosion problem, b)
unfairness of the deck can reduce midship transverse framing
stiffness, c) foundation fit up requirements, and d) personnel
safety in walking areas. However, due to the cumulative affect
of the different sources of distortion, often the fairness of
the deck is out of specifications.
manual straightening process is used to bring the decks back
into spec, but this is a costly non-value adding process that
consumes resources and
can affect construction schedules. The cost of removing this
distortion drives the cost of Navy hulls up 0.1 – 0.3%.
Portable Automated Plate Straightener (PAS-D) is the first
example of a portable unit possessing both robotic capability
and flexible automation in ship production. The system can
adjust to the changing environment in real time in order to
straighten the deck.
This system was designed and built with
collaboration with Northrop Grumman Ship Systems and Bollinger
