The United States Bureau of Safety and Environmental Enforcement (BSEE) has published Safety Alert 516, relating to potential risks involving compressed gas cylinders. 

What happened?

During the period 2024-25, multiple explosions were reported to the bureau and were linked to cylinder failures. Several of the explosions were severe, causing injuries and damage to facilities.

What was the response?

BSEE conducted a performance-based risk inspection, of 20 assets, including production platforms and well operations operated by 13 different operators across the Gulf region.

BSEE identified several key findings:

  • Over-reliance on offsite, third-party contractors to ensure adequate integrity of compressed gas cylinders.
  • Limited understanding of cylinder inspection programs and recharging processes.
  • Offshore personnel not familiar with cylinder markings, recertification dates, local regulatory requirements for compressed gas cylinders, or the shelf life of compressed gas contents.
  • Multiple compressed gas cylinders with no markings or information about their contents. No platform inspected used gas detectors to ensure cylinder integrity over time.
  • Offshore personnel were unaware of recent safety alerts published by BSEE and the International Association of Drilling Contractors (IADC) on the risks and the recommendations to lower the risks associated with compressed gas cylinders.
  • Some facilities with no compressed gas cylinder inspection programs. Cylinders containing the same gases stored together and secured, but cylinders with different pressure ratings stored in the same areas without adequate consideration. Some cylinders could not be inspected, and some had no markings or showed corrosion.
  • In some facilities, no compressed gas cylinder maintenance plans and sole reliance on third-party inspections.
  • Multiple cylinder racks in unprotected areas that did not allow for proper drainage, increasing long-term exposure to corrosive elements.
  • Operator and contract personnel not trained on how to inspect compressed gas cylinders, the risk associated with them, or best practices to prevent rupture incidents.


It is to be noted that the BSEE report does record some positive findings. Here, IMCA has focussed on the lessons to be learned. 

BSEE recommendations

  • Ensure industry safety alerts are properly shared with offshore personnel.
  • Ensure all compressed gas cylinders are stored by contents and pressure; be easily inspectable; have valve caps on when not in use and secured within a rack with chains, straps, or secured to a wall or support.
  • Inspect all cylinders and validate that every compressed gas cylinder is properly labelled with clear, durable content identification. Every cylinder should have marking requirements that include legible content names, hazard warnings, and any information required by local regulatory requirement.
  • Ensure offshore personnel have a full understanding of cylinder labels, markings and recertification dates.
  • Establish a thorough inspection criteria for compressed gas cylinders, inspections should be conducted by qualified personnel and properly documented.
  • Ensure there are written procedures for safe recharging operations.
  • Work with third-party vendors to ensure all cylinders sent offshore meet the appropriate regulatory requirements.
  • Ensure compressed gas cylinders are stored safely and subject to company procedures, local regulatory requirements and industry best practice.
