The Coast Guard and MODUs

The mobile offshore drilling unit (MODU) was developed as an alternative method for drilling in water environments. A MODU is a vessel that is capable of engaging in drilling operations for subsea resources. Early versions included towed barges or platforms and submersible barges that rested on the bottom. Many of the wells accessed by early MODUs were at depths of less than 30 feet. Today’s MODUs come in a range of varieties including jack-up rigs, self-propelled semi-submersibles, and spar-shaped units capable of drilling in depths up to 10,000 feet. The United States Coast Guard is involved in construction and inspection of MODUs that operate in U.S. waters.
