design life of the ship, including fatigue
analysis requirements, redundancy of
propulsion systems, unique requirements
for fire-fighting and other auxiliary
systems, and any specific requirements
for outfitting and habitability.
“Continued development of naval rules
requires a close working relationship
between the subject matter experts at
the class society and the Naval Technical
Authority or Warrant Holder in the

representatives,” says Ashe. “Our Naval
Technical Committee provides the forum
for us to do this.”
Since issuing its ABS High Speed Naval
Craft Guide in 2003, and the ABS Naval
Vessel Rules in 2004, ABS has issued
regular updates that have been developed
with the input and review of the Naval
Technical Committee. “The general goal
for ongoing rule development is to capture
new technology quickly, clarify and clearly

lessons learned,” Ashe explains. “In some
