successful record-breaking descent to the deepest part of

For more than forty years, McConaghy Boats in Sydney has
been solving complex composite engineering problems in the
marine, aviation, military and industrial markets.
Internationally recognised for building high-performance,
record-breaking racing yachts, McConaghy was approached
eighteen months ago to assist the explorer-filmmaker James
Cameron and his engineering partner, Ron Allum, with the
complex construction of the DEEPSEA CHALLENGER submersible,
a submarine capable of diving to the bottom of the Mariana
Trench in the Western Pacific, eleven kilometres down at the
deepest part of the worlds oceans - with Cameron himself
onboard as sole pilot.
The challenges involved in this project were immense. The
pressures involved at these extreme depths meant any faults
or voids in the materials or construction process could
prove catastrophic. During a three-month period, McConaghy
developed a solution for bonding more than two hundred and
fifty sections of the submersible's core-buoyancy material -
an extremely hard and high-strength composite foam structure
innovated by Cameron's team called ISOFLOAT® and forming the
5.8m main structure of the submersible. This beam had to be
constructed to withstand 16,500 psi (114MPa) of sea pressure
- allowing the main beam to become massively compressed at
its record-breaking depth at the base of the Mariana Trench,
resulting in the submersible becoming 60mm shorter than it
is at sea-level.
Having overcome the problem of bonding the core buoyancy
materials, McConaghy continued to work closely with the
Acheron Project, Cameron's and Allum's Sydney-based team,
fabricating 95% of all composites in the project, including
the main beam thruster units, doors, access panels and
Cameron and Allum spoke with McConaghy general manager
Richard Stanning just days before the submersible left
Sydney for sea-trials. They were delighted with both
McConaghy's commitment to the project and its engineering
capabilities. "It's safe to say we couldn't have done this
without the McConaghy team," said Cameron.
"Following explorer-filmmaker James Cameron's recent successful record-breaking descent to the deepest part of the worlds oceans, McConaghy Boats confirmed its significant involvement in this remarkable project."
