How Many People Can Stay on an Oil Rig Offshore?
The number of people that can stay on an oil rig offshore varies significantly based on the size and type of the rig. From small lift boats to massive semi-submersibles, the capacity can range widely, but it is always designed to ensure safety and efficiency. Let's dive into more details about the population dynamics of offshore platforms.
Large Offshore Projects: An Example
One of the most impressive oil rig projects I had the opportunity to work on involved a platform that could accommodate 175 people. In addition, we had a semi submersible "floatel" that held 750 individuals. This project was particularly large and located around 225 miles off the coast of Louisiana. The living conditions were not just tolerable but comfortable, with a top-notch chef who used to work on the Queen Mary. One can only imagine the sumptuous meals served on the floatel.
Depending on the Rig Size
While some offshore platforms can house thousands of people, others, like small lift boats, can only accommodate around 20 crew members. These smaller boats are typically used for maintenance and other smaller tasks. More substantial rigs, such as semi-submersibles, can certainly have larger capacities. For instance, a semi-submersible rig might be able to hold over 100 workers.
Mixed Operations: Barges and Semi-Submersibles
Some offshore platforms are not just unique because of their size but because of their mixed operations. For example, I once worked on a North Sea project that involved a large barge with its own crane, parked alongside a semi-submersible drilling rig. Both had planks connecting them to the main platform, and in bad weather, they pulled these up for safety.
These mixed operations created some fascinating dynamics. The barge had its own living quarters and even its own food facilities. It wasn't uncommon to see card games on the barge, and even some rather eye-opening scenarios. One time, I witnessed a pile of money on a table, totalling around 50,000 dollars, in various denominations. It was too much for me, so I withdrew—for a moment—to enjoy some of the excellent whiskey served there before returning to my duties as a roughneck.
Other critical aspects of working on these rigs include multiple helicopter decks. In good weather, it felt like a helicopter airport, bustling with activity. However, during storms, it could turn into a challenging environment with 80 mph winds and 60-foot seas. It was definitely a job that required a robust sense of adventure and resilience.
Conclusion
While some offshore platforms can be veritable towns housing thousands of workers, others may only accommodate a few dozen. The key is always to have a crew capacity that ensures both safety and efficiency—no matter how big or small the rig. These platforms have come a long way since my early days in the industry, and they continue to evolve to meet the demands of modern drilling operations.
