BSEE Inspection Identifies Welding and Burning Hazards

A string of high-potential fires in the Gulf of Mexico leads to inspections and recommendations to improve safety.

In September 2023, the Bureau of Safety and Environmental Enforcement (BSEE) carried out performance-based risk inspections (PBRIs) for 22 production and well operation sites in the Gulf of Mexico. An analysis of compliance and incident data since 2022 uncovered multiple high-potential fires associated with welding and burning operations leading to these on-site targeted inspections of 13 production facilities and nine well operation facilities operated by 11 distinct operators. An evaluation of those inspections identified several critical issues requiring attention to ensure the safety and integrity of ongoing operations.

The PBRIs revealed instances where fire protection barriers (e.g., tarps, curtains, and blankets) were either inadequately placed or damaged, posing a risk to the safety of welding and burning operations.

In one incident, evidence suggests hot slag from a cutting torch pierced the underside blanket barrier of the living quarters building. The residual heat likely caused the wood subfloor to ignite (Fig. 1).

The PBRIs identified the following concerns:

  • Hot work was being conducted in areas within 35 ft of equipment containing hydrocarbons.
  • Inadequate housekeeping practices were observed, with flammable sources such as cardboard boxes found within 35 ft of hot work areas, posing an additional risk to safety.
  • Tools for prevention, such as fire extinguishers and portable gas detectors, were not properly identified as necessary.
  • Operations were taking place without an approved Safe Welding Plan, indicating a need for comprehensive safety measures and planning.
  • Offshore personnel were not following safe welding and hot work procedures. For example, one procedure requires the designated person-in-charge to personally verify the individual performing the burning had been trained to safely operate the oxygen/acetylene burning equipment. BSEE found at least one instance of this not having occurred.
  • Frequency of training for hot work or welding was inconsistent. BSEE was unable to determine from the Safe Welding Plans or Safety and Environmental Management System Training Element if operators required individuals serving as welders to be trained and qualified to the appropriate industry standards and codes (e.g., American National Standards Institute, American Welding Society, American Society of Mechanical Engineers), relative to the specific type of hot work tasks being performed.
  • Hot work permits and Job Safety Analyses (JSAs) listed the same person to perform fire watch and perform the hot work.

 BSEE recommends that operators and their contractors, where appropriate, consider doing the following:

  • Taking all necessary precautions to control, remove, or otherwise correct any hazardous oil and gas accumulation or other safety, health, or fire hazard
  • Inspecting the rating, current condition, and placement of fire protection barriers to mitigate the potential risk caused by hot work, including personal protective equipment
  • Reviewing and mitigating any hazards associated with welding and burning operations, which warrant a heightened level of planning specific to the task’s risk
  • Reviewing training and competency requirements for hot work, ensuring these meet industry standards
  • Ensuring employees can understand and perform their jobs in a safe and environmentally sound manner
  • Ensuring all hot work operations are inspected by the person in charge prior to commencement of work and ensuring adequate supervision and fire watches are in place throughout the duration of the work
  • Adhering to all applicable planning and procedures for safe welding and hot work
  • Requiring all operations and contract personnel attend and participate in prejob job safety analysis meetings and ensuring the supervisors of all phases of the work know and understand the complete scope of the job
  • Ensuring compliance with 30 CFR, Section 250.46, Safe and Workmanlike Operations
