10. The first Spar was Kerr-McGee's Neptune, which is a
floating … facility anchored in 1,930 feet in the Gulf of Mexico.
11. Floating production systems are large ships equipped
with processing facilities and moored to a location for a … period.
12. … are mini TLPs of relatively low cost, used in water
depths between 600 and 3,500 feet. They can also be used as
utility, satellite or early production platforms for larger deepwater
discoveries.
13. The Spar may be more economical to build for small and
medium sized rigs than the TLP, and has more inherent stability
than a TLP since it has a large … at the bottom and does not
depend on the mooring to hold it upright.
14. Fixed platforms are economically … for installation in
water depths up to about 1,700 feet.
15. The first (and only) cell … is Kerr-McGee's Red Hawk.

Exercise 2. Are the following statements true or false?
1. Fixed Platforms built on concrete or steel legs anchored
directly onto the seabed.
2. Compliant towers are designed to sustain significant
lateral deflections and forces.
3. Semi-submersible rigs cannot be moved from place to
place.
4. Jack-up Platforms used in relatively low depths, are
designed to move from place to place.
5. Drill ships are used only for scientific drilling.
