1.3. General Information
The NEPTUNE JB is cylindrical, 13.2” (33.5 cm) in diameter by 40” (101.6 cm) in length. It
should be noted that this length does not include the SeaCon connectors which extend
approximately 1” (2.5 cm) beyond the end plate of the JB.
The JB weighs approximately 400 lbs (181kg) in air and approximately 202 lbs (91.5kg) in
fresh water.
The JB is equipped with the two following custom tooling items:
- NEPTUNE Lifting Frame Assembly, part number 0848-250-T30000
- NEPTUNE Assembly Alignment Fixture, part number 0848-250-T20000
The NEPTUNE Lifting Frame Assembly is designed to be used for both lifting and securing
the JB during transportation. The NEPTUNE Assembly Alignment Fixture is designed to be
used when inserting the JB chassis into the pressure vessel.
The JB is shipped in a custom fabricated crate. The crate empty weight is approximately 60
lbs (27.2 kg) and must be accounted for when handling the crated JB.
