Marlin AUV

High Volume Grab Subsea intervention specialist Marin has unveiled a versatile new high-volume grab tool designed for use across a range of applications, including large-scale brownfield clearance. The tool forms part of the EVO Marin Debris Recovery System (MDRS) and serves as proprietary technology capable of operating in harsh subsea environments to full ocean depth for the recovery and removal of assorted debris.

Lockheed Martin is leveraging its proven capabilities and technology with autonomous underwater vehicles (AUV) toward the application of the Marlin class of AUVs for use in offshore oil and gas, science and oceanography, and other applications.

window in high-seas states. These features coupled with modular high payload capacity and endurance allows Marlin to execute missions for commercial, scientific and military applications in a cost-effective manner.

The highly-advanced Marlin AUV has been developed for a range of civilian and military customers who require a quick and safe way to conduct subsea surveys and inspections. Packed with an array of sensors and capabilities that can be tailored to diverse customer requirements, the Marlin operates in challenging environments throughout the water column.

The Marlin AUV is well-suited for use in the oil and gas industry to inspect offshore structures and pipelines, especially after severe weather strikes, such as hurricanes. The Marlin’s high-resolution optical and acoustic sensor package can provide 3-D pictures up to 1000ft beneath the surface and rapidly inspect for potential damage, eliminating the need for divers in these dangerous conditions. The Marlin is able to operate in tight spaces, sprint up to four knots and cruise for up to 16 hrs.

The ten-foot long submersible, which can carry a payload of up to 25lbs , delivers key features unparalleled in the AUV market. The hydrodynamic design and thruster arrangement enables hover capability and high manoeuvrability in tight spaces. Vertical thrusters ensure operation from freshwater to seawater for missions in lakes, rivers, estuaries, harbours, ports, coastal regions and oceans. Fully integrated autonomous launch and recovery capability enables subsurface recovery extending the operational

“We developed the Marlin from our extensive AUV systems experience to fill a need in the commercial sector,” said Dan McLeod, Senior Program Manager Lockheed Martin MS2 business unit in Riviera Beach. “The Marlin’s advanced autonomous functions and cutting edge technology will deliver game changing capabilities for our customers.”

With a mobilised capacity of 40t3, the hydraulically-driven, multi-tined Evo MDRS grab can be deployed by single wire or by a remote actuation pack and operated via clients’ ROV intervention systems. The grab is the latest in a series of complementary proprietary tools in
