This illustration shows several types of offshore oil and gas structures. Various designs can be used for drilling, production management, crude storage and offloading:

#1 and #2 are conventional fixed platforms anchored to the seabed; 
#3 is a compliant tower; 
#4 and #5 are vertically moored tension leg and mini-tension leg platforms (#4 represents the design of the ConocoPhillips’ Magnolia TLP); 
#6 is a spar platform; 
#7 and #8 are semi-submersible platforms; 
#9 is a floating production, storage, and offloading facility; and, 
#10 is a sub-sea completion and tie-back to host facility.
