Introduction
 Cable s supply power to the ships
 Cable spools are currently stored on the ground
 They are getting damaged due to the sun, weather, &
waterfront activity
 Safety hazard
 Disorganized
 Spools in front are being used more than those in the
back
Problem Definition
 Racks need to be
adaptable to different
sized spools
 Cables must be stored in
the allotted area
 Forklift will be used to
load & unload the rack
