Why Do Oil Rigs Winterize? 6 Real Dangers for Rig Workers

Depending on their location and just how far temperatures drop, offshore oil rigs and land rigs can keep functioning through the winter. To make this as safe as possible, however, they must be winterized. This is a process where an oil rig is prepared for cold weather. When done right, winterization can protect workers, equipment, and production. When it’s glossed over or delayed, the results can be catastrophic.

Oil Rig Winterization & Winter Safety

Winter weather creates harsh conditions for oil rig equipment, piping, and instrumentation. Workers also face the risk of hypothermia, frostbite, and trench foot caused by exposure to freezing or near-freezing temperatures. When an oil rig is properly winterized and workers are given the gear and training to deal with the cold, the risks can be lowered significantly.

Winterizing an oil rig may include the following steps:

  • Planning – Companies must create detailed plans and checklists of every piece of equipment, instrument, pipe, and system that needs to be retrofitted for the cold. These plans must also outline exactly what to do if something goes wrong.
  • Training – Every single worker on an oil rig must be trained on how to work in cold weather, what gear to wear, how to handle winterized equipment, and the freezing points of every material they deal with.
  • Insulating – Proper insulation will reduce heat loss and will protect equipment, machinery, and instrumentation from the damaging effects of the cold. Outdoor equipment and piping must also be protected, with plans in place if a blockage, freeze, or leak occurs.
  • Maintaining – Maintenance is even more crucial during cold winter months, as low temperatures and significant temperature changes can put additional pressure on heavy machinery, instruments, pipes, and other equipment.
  • Slowing Down – Rushing any task on an oil rig is a dangerous idea. In the winter, workers should be particularly cognizant of the value of taking extra caution, walking slowly to avoid slipping on ice, checking equipment carefully in freezing temperatures, and more.

If temperatures are expected to drop too low or a storm is coming in, however, staying operational is not an option. In some cases, a well may need to be temporarily shut down in preparation for a freeze. In others, fixed rigs may need to be evacuated. Floating rigs may need to be moved to warmer waters.

When Rig Winterization Goes Wrong

Winterizing oil rigs is in the best interests of owners and operators, as production can continue and serious accidents can be avoided, but that doesn’t necessarily mean that they will do the right thing. In attempts to avoid shutdowns and the cost of replacing or maintaining equipment, some oil and gas companies may delay winterization, continue to work with aging equipment, or cut corners in educating and implementing workers on winter safety. Nothing good can come of this.

Oil rig workers face six main dangers when companies do not prepare for winter temperatures:

Danger #1: Faulty Instrumentation

Extreme cold or the combination of hot and cold temperatures can lead to condensation in critical instrumentation. Sensors may malfunction and signals may be interrupted, affecting readings that give rig operators the information they need to drill and extract natural gas. If instrumentation is improperly winterized or is not prepared for low temperatures at all, blowouts, leaks, and other serious accidents may occur.

Danger #2: Frozen Piping

Frozen piping is one of the primary hazards associated with cold temperatures. Water and other materials will expand if they freeze in pipes, and in some cases, water may mix with other substances to form solid hydrates, which can block piping. Frozen pipes may leak or crack. Removing a blockage in piping can be dangerous in itself. Improperly winterized piping and equipment on an oil rig can cause catastrophic explosions, fires, and other accidents.

Danger #3: Cold Stress Injuries

When oil rig workers are not provided with proper protection against winter weather, they can experience cold stress injuries. On offshore rigs and in oilfields, workers may be exposed to low temperatures and rain or sea spray, which can lead to trench foot. Other cold stress injuries include frostbite and hypothermia. Companies that do not winterize oil rigs put their workers' very lives at risk.

Danger #4: Ice, Snow & Slippery Decks

On a land rig or an offshore platform, ice and snow can make walkways, ladders, and stairs extremely hazardous. Without proper winterization, these surfaces can cause slip and fall accidents and even falls overboard that leave workers seriously injured or even claim their lives.

Danger #5: Equipment Failure

Equipment failure is a risk when an oil rig is not readied for cold, freezing, or near-freezing temperatures. Winterization should include inspecting, maintaining, and repairing equipment before low temperatures hit, as well as making additional preparations for cold fronts and storms. This can be an issue alongside frozen piping and faulty instrumentation.

Danger #6: Blowouts & Other Disasters

The worst oil and gas disasters happen when companies cut corners in maintaining equipment and implementing safety standards. This applies to winterization as well. It also applies to companies’ overall behavior when storms are about to strike, such as failing to evacuate crews from rigs or oilfields in areas that are going to be hit by heavy winter storms. Oil rig explosions, capsizing platforms, fires, and other catastrophes can be linked to failures to prepare for winter weather.

Rig Workers Deserve Safe Work Environments, Even in the Winter

It doesn’t matter how hot or how cold it gets. It doesn’t matter if a storm is rolling in. Oil rig workers deserve to be protected from the worst that Mother Nature has to offer, and in the winter, that means proper rig winterization. If you were injured on an oil rig in any weather, you deserve the chance to recoup your losses and get the treatment you need.
