A Global Leader in Classification

For more than 150 years, ABS has been at the forefront of maritime safety. Today the ABS Rules and Guides incorporate knowledge gather through our century and a half of operation, as well as the most advanced technological research.

What is Classification?

Classification is performed by a classification society such as ABS, which is a non-governmental organization that provides services through the development of standards called Rules. These Rules form the basis for assessing the design and construction of new vessels and the integrity of existing vessels and marine structures.

How Does Classification Work?

Implementing the published Rules, the classification process consists of:

  • A technical review of the design plans for a new vessel to verify compliance with the Rules
  • Attendance by an ABS or other classification society surveyor:
    • At the construction shipyard
    • At the relevant production facilities that provide key components
    • At sea trials
  • When these inspections are completed satisfactorily in compliance with the Rules, we issue a certificate of classification.

Once in service, the owner must submit the vessel to periodical onboard class surveys to verify that the ship continues to meet the relevant Rule requirements.

Why Class with ABS?

  • Proven legacy of providing best-in-class service for more than 150 years.
