Going off the deep end is all in a day's work for Kiewit Offshore Services. Founded in 2001, the company is a subsidiary of employee-owned Peter Kiewit Sons' that primarily acts as a contractor for oil and gas production customers operating off the coast of the Gulf of Mexico. It primarily manufactures and repairs offshore oil and gas platforms and large structural steel components. In addition to deepwater projects, Kiewit Offshore Services also builds small platforms, modules, suction piles, and tendons. After partnering with Bullwinkle Constructors to build the Bullwinkle Jacket (the largest oil-production platform and the time of its completion), Peter Kiewit Sons' formed Kiewit Offshore Services.
