The electrical construction package included concrete encased ductbanks,
low smoke, halogen-free 15kV cable, and the fire alarm, voice/data, and
security systems installations as well. The 200 foot tall, 7,000 ton capacity
Goliath Crane spanning drydock #4 was powered with a 13.2kV drive with a
cable trough and coiling draw-up system to accomodate crane movement and
a personnel elevator in the north east crane leg. The goliath crane was
manufactured in Portugal by Mague, owned by ABB. It was shipped across
the Atlantic in pieces and rigged into position by two cranes lifting the gantry
simultaneously over an 8 hour time period. The entire crane runs on rails
and is used to lower ship "blocks" into the drydock skidding system where they
are welded together and the ship is completed.
