The American Bureau of Shipping (ABS) is a leading classification society in the oil and gas industry. They provide services such as safety, environmental protection, quality assurance, risk management, research, and development for shipbuilding and offshore structures across all industries. This article will discuss how ABS helps keep your employees safe when they are onboard drilling vessels. 

This post will cover what you need to know about The American Bureau of Shipping (ABS) and drilling systems: who they are, their rules, standards, inspection services, type approvals, and what it means to you as an employer. We’ll also discuss why it’s important to have them around while working on a vessel or offshore drilling platform.

Who is The American Bureau of Shipping (ABS)?

The American Bureau of Shipping (ABS) is a leading provider of classification and technical advisory services to the maritime industry. Classification societies are responsible for the approval, periodic inspection, and certification of the construction, stability, subdivision, and operating conditions of ships over 500 gross tons.

ABS provides consulting services to both government and private clients in support of their quality assurance programs. ABS has four main lines of business: ABS classed fleets; ABS Consulting Services; ABS Inspection Services; ABS Research.

ABS Membership

The American Bureau of Shipping is an international classification society that provides services to the maritime industry to promote safety, security and environmental protection. ABS was founded in 1862 as the American Society of Civil Engineers.

ABS membership is open to any organization that supports ABS's mission, vision or values. ABS members include ship owners and operators, ship designers, contractors, naval architects, engineers, insurers, port authorities and other companies active in the maritime industry.

In addition, ABS has a fleet of more than 170 vessels and offices in more than 100 countries. ABS is also an accredited United Nations' ISM auditor and is headquartered in Houston, Texas, USA.

ABS Rules

The ABS Rules are ABS's guidelines for the construction and operation of ships, associated equipment, and engineering. ABS provides these guidelines as a service to international maritime regulation and practice. ABS Rules & Guides are derived from principles of naval architecture, marine engineering and related disciplines.

It's important to recognize that ABS is not an agency of any government, nor does ABS inspect or certify ships, their equipment, or operations; it is privately owned and governed by its members, who comprise some 96% of the world's fleet.

In addition, ABS represents not only the needs of its members but also those of its customers, other ABS member societies, and the public at large. For this reason, ABS serves clients in all areas of maritime trade. ABS has headquarters in Houston, Texas with additional offices worldwide.

Currently, ABS has more than 200 Rules, Guides and Guidance Notes available for download or purchase through the online catalog.

ABS Inspection Services

The ABS inspection services are performed to determine compliance with ABS rules and regulations for ships, as well as ABS engineering standards for a broad range of industrial structures.

ABS inspections are performed by ABS-certified inspectors, who have been trained to the ABS inspection level appropriate to the specific work they will be performing. Inspectors apply their experience and knowledge related to specific ship types, operational environments, and other relevant factors when reviewing a company's inspection results or preparing an ABS-type survey inspection.

ABS-certified inspectors can perform ABS type surveys and ABS class renewal inspections, as well as ABS special surveys.

ABS Standards

ABS Standards are comprehensive documents that ensure the safety, health and environmental performance of ABS type and ABS special survey vessels, ABS product tankers, ABS offshore structures. ABS standards are developed under guidelines by a consensus-based process involving ABS members and other subject-matter experts from around the world.

ABS Type Approvals

ABS type approval is an ABS approval for a specific device or design of equipment on ships, offshore units, and other marine-related facilities. To obtain ABS type approval for a device, ABS reviews the related requirements of the ABS rules to which it must comply.

Benefits of ABS Type Approval

The ABS type approval system provides ABS members and other interested companies with a means for demonstrating compliance with ABS rules. This is particularly important when either ABS has not adopted international consensus standards or when there are no relevant internationally recognized standards.

ABS type approvals may only be used in an ABS classification society survey if the equipment, device, or structure covered by ABS type approval meets ABS rules.

Some benefits of using ABS Type approved equipment include:

  • Streamlined acceptance of equipment and components on ABS-classed units and other marine and offshore applications
  • Demonstrated compliance with international/recognized standards and ABS Rules
  • Flexible certification approach to match business objectives
  • Avoid repeated evaluation of identical designs
  • Increased market visibility
  • Searchable in the ABS Type Approval Database

Guide For The Classification of Drilling Systems

The Guide For The Classification of Drilling Systems (CDS) discusses criteria for drilling systems that have been authorized by ABS and are designed to meet approved codes and standards. In other words, the guide provides a comprehensive approach to classing offshore drilling systems and their associated support systems.

The ABS CDS Guide is the latest international offshore drilling standards and practices, as well as input from industry experts. The document refers to other ABS Rules and Guides, as well as relevant industry codes and standards, in order to ensure that the information is comprehensive. From the wellhead to the top of the derrick, the Guide contains requirements for systems, subsystems, equipment, or components from the wellhead to the top of the derrick.

Similarly, the Guide also specifies engineering submittal requirements for drilling systems, subsystems, equipment, and components. The most recent drilling technologies have been added, as well as clarifying the technical and survey criteria for systems and components.

Why is it important to follow the ABS CDS Guide?

The abbreviation CDS is given to operators who follow ABS guidelines in this Guide for the Classification of Drilling Systems.

The number of ABS CDS-drilled rigs has increased by a factor of three in the last five years. Currently, over 70 oil rigs have been delivered with the CDS signifying that additional conditions have been satisfied for the drilling system, its subsystems, equipment, or components.
