Vessels

DSV Archie

The Archie is a 26′ steel, single-deck, yard-assist tug with flat forward and aft, square bow, straight-sided hull and square stern that offers unique capabilities in the diving industry. The flat deck acts as a working platform for dive and salvage operations. The vessel is fitted with a steel mast that supports navigation lights and air horns. An engine-driven air compressor and a single-hydraulic pump are stored within its hull. The deck house is two levels of welded steel construction and has a pilot house with no staterooms, galley mess area or crew head and is considered a day boat only. It is moored in Seattle, WA.

DSV Loon

The Loon is a 36′ fiberglass work scow. Its flat bottom and fully-operational bow ramp allow it to work safely in shallow waters and increase diversity for emergency spills and shore related work. The Loon is powered by two 115 horsepower, 4-stroke outboards attached to pipe racks and mounted directly to the transom. It is moored in Portland, OR.

DSV Munson

The 38′ aluminum Munson is primarily a diving support vessel. Since its initial purchase, the vessel has been meticulously upgraded with twin 150 horsepower, 4-stroke motors, new navigation and communication instruments, aluminum dive hose racks, gear storage lockers and extensive updates to the electrical and lighting systems to name a few. The vessel regularly has a dive compressor, dive umbilical hoses, standby air cylinders and other equipment on deck to respond to daily dive related work needs. The vessel is moored in Seattle, WA.

DSV Sand Island

The Sand Island is an 80′ by 25′ dive support vessel that berths 12 people. The vessel is powered by twin Cummins engines with a combined 700 horsepower. It has the capacity to make efficient crossings in the Cook Inlet Basin against extreme tidal currents. This allows shorter run times between tasks and can reduce travel times. The vessel also supports a deep diving air system and hydraulic tool support. It has enough deck space to support additional equipment as needed. The vessel is moored in Anchorage, AK.

MV Dawn

This 43′ Gulf Coast Crew Boat was converted to support surface-supplied diving and marine construction operations. It provides a stable, self-contained platform with rapid deployment capability ideal for ship husbandry, inspection, and support for marine construction projects. The Dawn is an ideal platform to support shallow water diving projects throughout the Bay Area and outside the Golden Gate. The vessel is moored in Port Richmond, CA.

MV Prudhoe Bay

Originally built as a landing craft and utility vessel for use on the North Slope of Alaska to transport cargo and equipment into shallow waters, the 62’ twin engine Prudhoe Bay was completely retro-fitted in 2008. It is regularly employed for diving and salvage work, but also supports marine drilling operations.

The Prudhoe Bay has a Gateway 5-ton, 4-function deck crane on a raised pedestal. The deck is equipped with two winches specifically for raising and lowering the I-beam supported and expanded metal bow ramp. The bow ramp allows for shallow water landings and added deck space when in the lowered position. Also on deck are four pneumatic anchor winches with localized controls to keep the vessel positioned while moored. In addition to other deck-related equipment, the Prudhoe Bay is accompanied by an 18’ aluminum outboard support boat as well as a surface control van for diving operations. The vessel in moored in Seattle, WA.

RV Elwah

The Elwah is an ideal platform to support shallow water diving projects. It provides a stable, self-contained platform with rapid deployment capability ideal for ship husbandry, inspection, and support for marine construction projects. The vessel has a small, enclosed cabin for the set up of electronics and dive support equipment, and a large open deck area forward.

The Elwah has a shallow draft and a bow ramp, enabling work in shallow areas, mudflats, and in locations with limited access for the rapid loading and unloading of equipment and personnel. A 1,000 pound rated ‘A-Frame’ on the bow of the vessel also assists with loading equipment via the ramp and supports diving and ROV construction activities. The vessel is moored in Seattle, WA.

Steadfast

Used predominantly for pre-boom operations, the 32′ Steadfast is a multifaceted combination work boat. With a wide open back deck and stern, she is well suited for anchor handling, boom towing and maintenance. A 6kw Northern Lights generator provides 110v power for seven sodium floodlights allowing for nighttime operations. Steadfast is powered by a 440hp Lugger main engine which, in addition to propulsion, also drives continuous flow hydraulics at 30gpm. A 10” Naiad Bow thruster allows for superior maneuverability. Steadfast has a full compliment of wheelhouse electronics as well as wireless internet. The vessel is moored in Anacortes, WA.

Tug

This 18’ pushboat is the workhorse on many of our marine construction projects.  She is powered by a Detroit 4-53N motor providing 140 HP to a 26” wheel through a Twindisc transmission.  A single rudder with twin flanking rudders provides extra maneuverability.  Two Beebee winches are mounted on board to assist with barge assembly and other tasks. She has a removable house and stack, so she is easily transported to inland jobsites on any type of trailer.

Portable boat fleet

Working alongside Global’s larger vessels are a variety of smaller aluminum, steel, and fiberglass boats. A majority of the smaller aluminum vessels are dedicated to spill response booming contracts, such as the fleet of 14′ skiffs and 16′ Tuff boats. We own three fiberglass Boston Whalers generally deployed for oil booming operations, but also fully capable of shifting to dive and salvage vessels.

We own and operate a diverse fleet of vessels to service a variety of needs. Our vessels support diving and salvage projects, environmental cleanups, and other marine services.

Our fleet ranges from small skiffs to large landing crafts and dive-support vessels capable of operating in harsh environments, such as Cook Inlet in Alaska. We also maintain select barges as diving platforms for projects requiring larger work areas.
