The American Bureau of Shipping (ABS) was chartered in 1862 to certify ship captains. Since then, it has been involved in developing and setting safety and quality standards for ships and offshore structures. ABS standards are recognized globally and are used to ensure that the materials, parts and components, and construction of vessels and marine equipment meet established safety standards. ABS works with the marine industry worldwide as they develop new technologies for constructing marine vessels and offshore structures, revising and updating its certifications to meet the changing industry needs.
The Rules and Grades established by ABS for certification are written to provide standards for the design, construction, and periodic survey of marine vessels and offshore structures to promote their safe design and assembly. Materials, parts, and components used in the manufacture of marine vessels and structures must meet the set standards for the vessel or structure in which they will be used.
Certifications are specified by the Rules, such as Steel Vessel Rules part 2-3-7/1, or MODU (mobile offshore drilling unit) Rules, or the material grade, such as Grade 2, or Grade 4C.
The end use of the component determines the inspections and certifications required, as well as any requirements for inspections during manufacturing:
Information about ABS certifications can be found at www.eagle.org.
ABS certification costs time and money. Certification inspectors are on-site at your facility during manufacturing, construction, or fabrication to verify that your processes meet the standards - and you pay for the time they are on-site. So, it’s important that you understand the Rule requirements for your product to identify the stages in your supply chain where inspection and certification should occur. By doing so, you’ll save your company time and money, and minimize the risk of your products not being certified. Some simple steps can provide you with cost and time savings.

With some planning, answering a few questions, and partnering with your suppliers, you can improve the efficiency of your production and reduce the costs of certifying your products for use in the marine industry.
Answering a few questions will help:
Which ABS Rules or ABS Grade applies to your product?
What is the application that your component will be used for? For example, are you manufacturing a component for a jacking system (or the complete system), torque-transmitting parts, or a structural component? The application helps determine the section of the Rules or Type Approval Tier that is appropriate for your part.
What is the end-use of the part? The end use of the part is also used to determine which ABS Rule, Grade or Type Approval Tier is required. For example, if your part is a component in a tail shaft, the process required may be different than if it is being used in rudder stock.
Do you have an ABS-approved drawing or Design Approval Document? These drawings or documents show that ABS has approved the design as well as provide an approval number for reference.
Partner with your suppliers.
It is critical to flow-down your ABS requirements to your suppliers...and your entire supply chain. This is the most important aspect to ensure your component will be accurately certified. It may be required for your suppliers to have an inspection performed during the manufacturing process. Clear requirements throughout the supply chain ensure that your component is manufactured under the certification requirements without delays or added costs.
Often, by the time the purchase order is submitted to raw material vendors, the ABS Rule requirements are missing. This is caused because the requirements were not flown-down the supply chain.
An ideal PO includes information on all the ABS Rules and Grades or the Design Approval Document from ABS.
Your supplier should work with you to ensure that the inspections and certifications are handled at the most effective point in the manufacturing process, eliminating time-consuming errors and reducing inspection costs.
It is helpful to have a supplier that is approved by ABS. Using certified suppliers can further minimize the cost and lead-time of inspections (ex: if you need a forging where final heat treatment will take place at another level within the supply chain, and the forging facility is an ABS- Approved supplier, then an inspection may not be required at the forge level).
