ABS has experience with a wide range of naval vessels including non-nuclear combatants, high-speed naval craft, patrol vessels and all types of auxiliary ships. In addition to the US, we have worked with the Navies of nations across the globe including: Australia, Canada, Chile, Colombia, Denmark, Ecuador, Egypt, India, Israel, Italy, Mexico, New Zealand, Oman, The Philippines, Saudi Arabia, Singapore, South Africa and others. We maintain engineering offices that specialize in naval vessel design review in Washington DC, Houston, Texas and Sydney, Australia.
We are able to provide continuity regarding the engineering aspects of certification. Our main objective is to verify that the design, construction and installation of systems, equipment and components will safely meet performance requirements.
ABS can offer more detailed analyses to meet specialized client needs. Our large corporate research and development team performs linear and non-linear hydrodynamic analyses, complete structural direct analysis, vibration analysis and spectral fatigue analysis (SFA) among others.
Under the ABS Naval Vessel Rules initiative, the Navy maintains its role as the technical authority. ABS functions as an independent certification agent and executes surveys in an autonomous manner.
