Offshore jobs vary a lot in length, and the answer depends on the sector, the type of role, and the contract you sign. Most offshore assignments run anywhere from a few weeks to several years, with rotation schedules that bring you home regularly in between. Whether you are just exploring the idea or ready to apply, here is a practical overview of what to expect.
What does an offshore job actually involve?
An offshore job is any role carried out away from shore, typically on a vessel, platform, wind farm, or other marine or subsea installation. You live and work on site for a set number of days, then return home for an equally structured rest period. The work spans a wide range of roles, from hands-on technical and operational positions to engineering, surveying, and project management.
Offshore work is project-driven by nature. That means your day-to-day tasks, your location, and even your team can change from one assignment to the next. You might be on a drilling platform in the North Sea one month and on a cable-laying vessel in the Baltic the next. That variety is one of the main reasons people are drawn to it.
The environment is demanding but structured. Safety is taken seriously across the board, and most employers require specific certifications before you can set foot on site. Think BOSIET, HUET, or STCW for maritime roles. These are not optional extras but standard requirements for any offshore placement.
How long are offshore jobs typically?
Offshore jobs typically last anywhere from two weeks to several years, depending on the sector and contract type. Short-term assignments in construction or installation can run just a few weeks, while longer operational roles on production platforms or vessels often stretch to six months, a year, or beyond. Many professionals work a series of back-to-back contracts over a career spanning decades.
The length of an assignment is usually tied to the project scope. A single offshore wind turbine installation campaign might last three months. A crewing position on a survey vessel could be renewed season after season. Production roles on oil and gas platforms tend to offer the most stability, sometimes running for multiple years with the same operator.
It is worth noting that contract length and time offshore are two different things. A twelve-month contract does not mean twelve months at sea. It means you are employed for that period, working within a rotation schedule that brings you home regularly.
What is an offshore rotation schedule and how does it work?
An offshore rotation schedule is the pattern that defines how long you work offshore and how long you spend at home. The most common schedules are 2 weeks on / 2 weeks off, 4 weeks on / 4 weeks off, and 28 days on / 28 days off. Some sectors use longer rotations, particularly in remote locations where travel time makes shorter trips impractical.
Here is a quick overview of the most common rotation patterns:
- 14/14: Two weeks offshore, two weeks at home. Common in the North Sea and European renewables.
- 28/28: One month on, one month off. Widely used in oil and gas globally.
- 6/6 weeks: Six weeks on, six weeks off. Often used in more remote or longer-haul projects.
- Voyage-based: No fixed rotation. You join a vessel for a voyage and return when it docks. Common in maritime crewing.
Your rotation is agreed before you start and forms part of your contract. In practice, rotations can shift slightly depending on operational needs, but any significant change should be communicated in advance.
What’s the difference between a contract and a permanent offshore position?
The key difference is employment security and flexibility. A contract offshore position is time-limited, tied to a specific project or period. A permanent offshore position offers ongoing employment with a single operator, with no fixed end date. Both involve the same rotation-based working pattern, but the employment relationship and financial structure differ significantly.
Contract work tends to offer higher day rates and more flexibility to move between projects and locations. It suits professionals who want variety or who are building a broad portfolio of experience. The trade-off is less job security and the need to manage your own availability between contracts.
Permanent positions offer stability, benefits, and a clearer career path within one organisation. They are more common in larger oil and gas operators or established shipping companies. For professionals who prefer predictability, a permanent role is often the better fit.
Many people start with contract work to build experience and then move into permanent roles later, or vice versa. Neither path is better in absolute terms. It depends on what you value at a given stage of your career.
Which offshore sectors offer the longest or shortest assignments?
Assignment length varies noticeably by sector. Oil and gas production roles tend to offer the longest and most stable assignments, sometimes running for years. Offshore wind installation and civil marine projects are typically shorter and more campaign-based, often lasting weeks to a few months. Maritime crewing follows voyage or contract cycles that vary widely by vessel type and trade route.
| Sector | Typical assignment length | Rotation pattern |
|---|---|---|
| Oil and gas (production) | 6 months to several years | 28/28 or 14/14 |
| Offshore wind (installation) | 4 to 16 weeks per campaign | 14/14 or project-based |
| Maritime crewing | 2 to 9 months per voyage | Voyage-based |
| Civil and tunnelling (marine) | 3 to 12 months | Project-based |
| Survey and inspection | 2 weeks to 6 months | 14/14 or 28/28 |
If long-term stability matters most to you, oil and gas production or a permanent maritime role is worth prioritising. If you prefer variety and shorter bursts of work, renewables installation and survey roles offer exactly that.
How do you find and apply for an offshore job?
To find and apply for an offshore job, start by identifying the sector that matches your skills and certifications, then connect with specialist recruiters or crewing agencies who work in that space. General job boards rarely carry the best offshore roles. Most positions are filled through industry networks and specialist agencies with direct client relationships.
Here is a practical approach to getting started:
- Get your certifications in order. BOSIET, STCW, and relevant trade qualifications are the baseline for most offshore roles. Check what is required for your target sector before applying.
- Build a clear, relevant CV. List your certifications, relevant equipment experience, and any previous offshore or marine work. Be specific about vessel types, project environments, and your role.
- Register with a specialist agency. Offshore recruitment works differently from onshore hiring. Agencies with dedicated offshore desks have access to roles that are never publicly advertised.
- Be clear about your availability and preferences. Agencies match candidates to roles based on availability, rotation preferences, and location. The more specific you are, the better the match.
- Browse active vacancies regularly. New offshore roles open constantly as projects are awarded and crewing needs change. Check offshore job vacancies regularly to stay ahead of new openings.
If you are new to the sector, do not be discouraged by experience requirements. Entry-level offshore roles exist, particularly in support and deck crew positions. The important thing is to have the right safety certifications and a willingness to work in a demanding environment.
