The US oil and gas industry — centred on the Gulf of Mexico (GoM) offshore sector, the Permian Basin in West Texas and New Mexico, the Eagle Ford Shale in South Texas, and the Bakken Formation in North Dakota — employs hundreds of thousands of workers directly, with the GoM alone producing approximately 1.9 million barrels of oil per day in 2025. Working on an offshore rig or oil field requires specific mandatory certifications that are legally required before you can set foot on a platform.
Mandatory certifications for US offshore workers
The offshore oil and gas industry is heavily regulated. These certifications are non-negotiable for any offshore role — operators and contractors will verify your credentials before you board a helicopter to a platform:
1. TWIC Card (Transportation Worker Identification Credential)
The TWIC card is issued by the Transportation Security Administration (TSA) and is required for workers who need unescorted access to secure areas of US maritime facilities and vessels. For Gulf of Mexico offshore workers, a TWIC card is required by most operators. To obtain a TWIC card:
- You must be a US citizen, lawful permanent resident (green card holder), or have valid immigration status
- Pass a TSA threat assessment including an FBI criminal history check
- Submit biometrics (fingerprints, photo)
- Pay the enrollment fee (approximately $125.25 for 5-year card, as of 2026)
- Certain criminal convictions are permanently disqualifying (including felonies involving terrorism, treason, espionage, murder, and others)
- Processing typically takes 6–8 weeks — apply well before you need it
2. BOSIET (Basic Offshore Safety Induction and Emergency Training)
BOSIET is the mandatory baseline safety qualification for every person working offshore globally, including US GoM operations. No BOSIET, no platform access. It covers:
- Helicopter underwater escape training (HUET) — what to do if your offshore helicopter ditches in water
- Sea survival — life raft use, group survival, hypothermia prevention
- Firefighting — basic fire prevention and response
- Emergency response and first aid
BOSIET must be issued by an OPITO-approved training center. It is valid for 4 years, after which you must complete BOSIET Refresher training. Cost: approximately $700–$1,200. You must have a medical certificate of fitness for offshore work before enrolling.
3. H2S Alive / H2S Safety Training
Hydrogen sulfide (H2S) is a highly toxic, colorless gas that can occur naturally in oil and gas operations. H2S training teaches workers to recognize hazards, use detection equipment, and respond to H2S incidents. Required for all oil field and most offshore roles. Typically 8 hours, renewed annually or every 3 years depending on the employer.
4. OPITO MIST (Minimum Industry Safety Training)
MIST is a standard safety induction covering permit-to-work systems, hazard identification, manual handling, and risk management — required for US GoM operations. Often completed online (theoretical component) with a brief practical assessment.
5. HUET (Helicopter Underwater Escape Training)
Sometimes included within BOSIET, sometimes a standalone requirement. Covers procedures for evacuating a helicopter that has ditched in water and inverted. Required for all personnel who travel to offshore platforms by helicopter — which is essentially all GoM offshore workers.
Medical requirements for offshore work
All offshore workers must hold a valid offshore medical certificate confirming fitness for offshore duty. In the US GoM context, operators typically accept an OGUK (Oil and Gas UK) offshore medical certificate or equivalent. The medical includes vision, hearing, cardiovascular, musculoskeletal, and psychological assessments. Some operators have additional requirements including specific body weight limits related to helicopter harness sizing — check operator requirements before completing medical.
Key documents to include on your oil/gas resume

- Well control certification (IWCF or IADC WellCAP) — for drilling, completions, and well services roles
- Any trade certifications (electrical, mechanical, welding) relevant to your role
- OSHA 10 or OSHA 30 (general industry or construction)
