Anchor-handling towing supply vessels

Tidewater's large, powerful anchor-handling towing supply vessels, capable of all types of towing and anchor-handling activities, are the most versatile vessels in its fleet. Fitted with experienced crews and the most up-to-date equipment, these vessels are capable of positioning and mooring drilling rigs in any location, at virtually any depth and under any conditions.

With a wide range of power, sizes and capacities, Tidewater’s anchor-handling towing supply vessels provide general offshore support service, drilling rig support functions and cargo transport assignments.

General-purpose supply vessels

Few vessels in Tidewater’s fleet can match the "work horse" persona and versatility of these general-purpose supply vessels (PSVs). PSVs are designed to carry a wide variety of cargoes and can transport large amounts of fuel, drilling fluids, cement or mud in tanks beneath the deck, while their spacious, open decks transport large quantities of other materials such as casing, drill pipe, tubing and miscellaneous deck cargo.

Towing and anchor-handling offshore tugs

Tidewater’s offshore tugs, the largest fleet in the industry, offer complete flexibility in all offshore towing markets for any project size and any location. Its tugs perform conventional towing and anchor-handling functions within a wide range of offshore applications, including rig towage and construction support. Additionally, Tidewater’s offshore tugs are employed in the coastal and ocean towage of both containerized and bulk cargoes.

Fast crew supply vessels

Tidewater's crewboats have the capacity to transport moderate quantities of cargo and as many as 150 passengers at high speed and in comfort. With the versatility to meet a variety of production needs in demanding conditions throughout the world, no vessel surpasses Tidewater’s crewboats.

Utility vessels

Ranging from 85ft to 150ft in length, Tidewater's utility vessels can be configured to meet an endless array of special needs. These versatile vessels generally support production in the field, functioning as all-purpose vessels to support diving operations, offshore structure maintenance and low-cost general assistance.
