The lowest position in offshore work is typically called a roustabout (on oil and gas rigs) or a general assistant (in other offshore sectors like renewables or marine). It is a hands-on, entry-level role that requires no prior offshore experience. You do physical work on deck or around the installation, support the crew, and learn the ropes from day one. It is the standard starting point for anyone looking to build a career offshore.
What does an entry-level offshore worker actually do?
A roustabout or general assistant handles the physical, day-to-day tasks that keep an offshore installation running. Think cleaning decks, moving equipment, maintaining tools, painting, and supporting more senior workers during operations. You are the backbone of the crew, and the role gives you a front-row seat to how everything works offshore.
The work is physical and the hours are long. Most offshore roles run on a rotation schedule, meaning you work a set number of days on the installation and then get an equal number of days off onshore. Common rotations are 14 days on and 14 days off, or 28 days on and 28 days off.
What makes the roustabout role so useful as a starting point is the exposure. You work alongside riggers, mechanics, electricians, and supervisors every day. You pick up skills fast, and you start to understand which direction you want to take your career.
What qualifications do you need for an entry-level offshore job?
To start in an entry-level offshore position, you typically need a Basic Offshore Safety Induction and Emergency Training (BOSIET) certificate, a valid medical certificate (like an ENG1 or offshore medical), and in some cases a survival at sea certificate. These are the baseline requirements for most offshore roles globally.
You do not need a degree or years of experience to get started. What employers and crewing agencies look for at this level is:
- A valid offshore medical fitness certificate
- BOSIET or HUET (Helicopter Underwater Escape Training) certification
- A willingness to do physical, hands-on work
- A basic understanding of safety procedures
- Reliability and a good attitude on the job
At iPS, we screen all candidates against QHSE requirements and international safety standards before any placement. This is a non-negotiable part of how we work, and it protects both you and the client.
Some roles in renewables or civil offshore projects may also ask for specific trade certificates, but at the entry level, safety training is always the priority.
How does the offshore job hierarchy work?
The offshore job hierarchy moves from general labor at the bottom to senior management and specialist roles at the top. Here is a simplified overview of how the structure typically looks in oil and gas, though it is similar across renewables and marine projects:
- Level 1 (Entry): Roustabout, General Assistant, Deck Hand
- Level 2 (Skilled): Roughneck, Able Seaman, Junior Technician
- Level 3 (Experienced): Derrickman, Crane Operator, Electrician, Welder
- Level 4 (Supervisory): Driller, Foreman, Chief Officer
- Level 5 (Management): Tool Pusher, Offshore Installation Manager (OIM), Captain
Each step up requires more experience, additional certifications, and often a strong track record from your previous role. The offshore world rewards people who show up, work hard, and keep building their skills. Moving up is realistic, not just theoretical.
You can explore the offshore and maritime industries we work in to get a better sense of where entry-level roles exist across different sectors.
How long does it take to move up from the lowest offshore position?
Most people move up from an entry-level offshore position within one to three years, depending on how actively they pursue additional certifications and how much time they spend offshore. The more rotations you complete, the faster you build experience and credibility.
A typical progression from roustabout to roughneck, for example, can happen within 12 to 18 months if you stay consistent and pick up the right safety and technical certificates along the way. Moving into a supervisory role usually takes at least three to five years of accumulated offshore experience.
A few things that speed up progression:
- Completing additional training courses between rotations
- Asking for more responsibility on the job
- Building a strong safety record
- Working across different projects or regions to broaden your experience
- Networking with colleagues and supervisors who can recommend you for the next step
Offshore careers are genuinely merit-based. If you perform well and keep learning, the path upward is open.
How do you apply for your first offshore job?
To apply for your first offshore job, you need to get your safety certifications in order, then register with a crewing agency or apply directly to offshore operators. Most entry-level offshore workers find their first role through a recruitment or crewing agency rather than applying directly to companies.
Here is a practical step-by-step approach:
- Get your offshore medical certificate from an approved medical examiner
- Complete your BOSIET or HUET training at a certified training center
- Update your CV to highlight any relevant physical work, safety awareness, or technical skills
- Register with a crewing or staffing agency that specializes in offshore recruitment
- Apply for open entry-level vacancies and be flexible about location and rotation schedule
Browsing current offshore vacancies is a good way to see what roles are available right now and what each one requires. This gives you a realistic picture of the market before you invest in training.
