You can find offshore job openings all over the Internet at literally hundreds of websites. These job openings you see posted at so many websites are vacancies in the Offshore Industry which vary from Entry-Level jobs to Professional positions which require experience and an education.
You can always find work in the Offshore Oil & Gas Industry, this is mostly because many jobs are contract based for short periods of time (e.g. 3 months) or long term contracts (for a couple of years). Once the project is completed, most employees lose their jobs. Therefore, many employees go from project to project, this is also why working internationally is an adventure, which you will never experience when working a day job at the office.
The advantages of working offshore are the divers worldwide locations you may work at, but also the work schedule (working 28 days on / 28 days off) are absolutely great. You gain a lot of experience, and the job is challenging & adventurous to say the least. You may even (at your boss’s expenses) be relocated, your airfare gets paid for, you travel to your job location by helicopter, and your income is grand.
Unfortunately, the disadvantages weigh just as heavy, as you won’t have a steady job which may last till you retire. You will need to apply regularly to new job openings just to be able to keep working. And since you and you colleagues are all fighting for the same jobs, the competition is high. Your job also entails workdays from 12 up to 16 hours a day (or more), and you will be away from your home and family for long periods of time.
