When the tide of offshore energy activity rises, Tidewater chooses to chance the wave. The company's fleet of about 300 vessels provides oil and gas exploration, field development, and production support. Services encompass transporting crews and supplies to offshore platforms, towing of and anchor handling for mobile rigs, and aiding in offshore construction and seismic operations. Its fleet includes towing-supply and supply vessels, deepwater vessels, crewboats, utility vessels, and offshore tugs. In addition to support ships, Tidewater owns Quality Shipyards, which builds, repairs, and modifies vessels for its parent and third parties. About 70% of Tidewater's revenues are generated in international waters.
