American Bureau of Shipping (ABS)

The American Bureau of Shipping (ABS) is a classification society, founded in 1862, with a mission to promote the security of life, property, and the natural environment in the maritime industry. It sets safety and environmental standards for ships, offshore structures, and maritime-related facilities.

Key takeaways

  • Definition: The American Bureau of Shipping (ABS) is a U.S.-based classification society that sets and enforces safety and environmental standards for maritime assets like ships and offshore structures.
  • How it works: Companies consult ABS for expert guidance on maritime projects, going through phases such as design evaluation, construction oversight, and rigorous inspections, all aimed at ensuring compliance with globally recognized 
  • Types: ABS provides a wide range of services including vessel classification, engineering reviews, and environmental compliance among others.
  • Pros and cons: Advantages include rigorous safety standards, global reach, and comprehensive services. Disadvantages could include high costs, complexity, and time-consuming processes.
  • Explore your options: Understanding ABS's role and methodology empowers maritime companies to align their operations with global standards, thereby achieving safety, efficiency, and environmental responsibility.

How it works

The American Bureau of Shipping (ABS) serves as a foundational pillar in the maritime sector, helping companies achieve safety and environmental excellence. When companies embark on maritime projects, they consult with ABS to ensure alignment with globally recognized standards. The consultation phase is a vital step to identify and mitigate potential risks and inefficiencies.

Once onboarded, companies undergo an in-depth design evaluation. This process helps ensure the blueprints align with existing safety norms and eco-friendly practices. After gaining design approval, projects move to the construction phase, which comes with robust oversight to prevent any lapses in compliance.

Inspections are a mainstay throughout the building or retrofitting processes. ABS conducts thorough examinations to validate that each structural and functional component adheres to predetermined standards. These evaluations are essential in building stakeholder confidence and ensuring operational safety.

After successful inspections, assets are awarded the coveted ABS certificate. This certification is not just a one-time event; it requires ongoing commitment to standards via periodic renewals. This ensures that vessels or structures continue to meet evolving industry norms.

ABS's engagement doesn’t end with certification; it extends into the operational lifecycle of the maritime asset. Continuous monitoring and auditing activities are conducted to ensure enduring compliance and operational excellence. Through this comprehensive process, ABS remains a stalwart advocate for maritime safety, efficiency, and environmental stewardship.

By grasping the functional framework of ABS, maritime organizations can better strategize their projects, ensuring they meet or surpass industry standards in safety, efficiency, and environmental impact.

American Bureau of Shipping service types

ABS offers a comprehensive suite of services designed to ensure maritime safety, environmental compliance, and operational efficiency across a range of vessel types and offshore structures.

Let's delve deeper into the five main types of services ABS offers:

Vessel classification

ABS evaluates ships, such as cargo vessels, tankers, and passenger ships, against a set of established criteria for design, construction, and maintenance. This ensures that the vessels are structurally sound, safe, and environmentally responsible. The classification also helps ship owners in securing insurance and meeting international regulations.

Offshore structure certification

ABS has particular expertise in certifying offshore installations like oil rigs, floating production units, and renewable energy structures like wind farms. Through rigorous inspections and assessments, ABS ensures that these facilities meet safety and environmental standards. This is crucial for minimizing risks in high-stakes, hazardous environments.

Engineering design reviews

Before construction or retrofitting begins, ABS reviews engineering designs and blueprints for ships and offshore structures. Their experts provide insights to enhance structural integrity, safety features, and operational efficiency. This preliminary step can prevent costly errors and ensure alignment with industry standards.

Maritime safety management

Through audits and certifications, ABS helps organizations implement effective Safety Management Systems (SMS). These programs cover everything from operational protocols to emergency response plans. By attaining SMS certification, maritime companies demonstrate a commitment to safety and regulatory compliance, which can be beneficial for their reputation and operations.

Environmental regulations

The environmental services offered by ABS aim to reduce the ecological impact of maritime activities. This involves certifications related to emissions control, ballast water management, and waste disposal. By helping operators meet or exceed environmental regulations, ABS plays a role in sustainable maritime operations.

Each of these services is designed to address specific aspects of maritime safety, efficiency, and environmental responsibility.

Pros and cons


  • High standards: ABS enforces rigorous safety and environmental standards. This ensures that vessels and offshore structures meet global best practices, reducing the risk of accidents and environmental harm.
  • Global reach: ABS has a global network of offices and experts, making it accessible to shipping companies worldwide. This helps maintain a consistent standard of safety and environmental compliance across different jurisdictions.
  • Reputation: Being certified by ABS is often viewed as a mark of quality. This can increase the value and marketability of ships and offshore structures, providing a competitive edge to owners.
  • Comprehensive services: ABS offers a wide range of services including surveys, audits, and training. This one-stop-shop approach makes it convenient for maritime businesses to meet all their certification and compliance needs.
  • Technical expertise: ABS employs experts with deep knowledge of maritime engineering, navigation, and environmental sciences. Their guidance can significantly improve the design, construction, and operation of marine assets.


  • Cost: The process for gaining ABS certification, which includes inspections, audits, and possibly modifications, can be expensive. For small operators, this financial burden could be prohibitive.
  • Complexity: The regulations and standards set by ABS can be intricate and difficult to understand. Companies often need to hire experts to help navigate these requirements, adding to the overall cost.
  • Time-consuming: Certification involves multiple steps and rigorous inspections that can take a long time to complete. Delays in certification can impact the operation and profitability of maritime assets.
  • Reliance: Companies that rely solely on ABS for certification may miss out on alternative, potentially more suitable standards or methods offered by other organizations. This lack of diversity could limit the perspective on safety and efficiency.
  • International limitations: ABS is an American-based entity, and its standards may sometimes conflict with local regulations or practices in other countries. Navigating these conflicting requirements can be a significant challenge for international operators.
