Offshore drilling involves various other operations other than drilling. Offshore drilling is a tedious operation. It is more demanding when compared to onshore operations. This is due to the harsher environmental conditions and remote areas where the drilling takes place. A floating system may be lower in expense in the offshores than a fixed platform; offshore manned facilities also present logistics and human resource challenges. An offshore oil platform is a small community in itself. They have the requirements with cafeteria, sleeping quarters, management and other support functions and a few recreational options sometimes.

A chopper transports the staff members for their required shifts, and the duration depends on their contract. The man force working offshore usually receives a higher salary than onshore workers do. Supplies and waste are transported by a ship. The supply deliveries need careful planning due to limited storage space on the platform, and it should maintain a balance on the platform. The platform will not be able to hold too much weight. The dynamic nature of the platforms introduces many challenges for the drilling and production facilities. These challenges are tended to with the help of the many globally active firms like the ones listed above.
