Metal Shark, Sea Machines launch new autonomous vessel

Louisiana shipbuilder Metal Shark and Sea Machines, a Boston-based developer of autonomous marine technology, have introduced a new 29′ autonomous vessel. The vessel is being offered through Metal Shark’s Sharktech autonomous division.

The new Sharktech 29 Defiant welded aluminum monohull pilothouse vessel features OEM-integrated Sea Machines technology offering a full range of advanced capabilities including active control and collision avoidance. The system allows for either traditionally manned, reduced-crew or unmanned autonomous operations to deliver “human-in-the-loop” navigation capabilities during both line-of-sight and over-the-horizon operations.

Sea Machines and Metal Shark recently began demonstrations using the new platform, and units are now available for acquisition by government and commercial operators under Metal Shark’s stock boat program.

“While many people still think of autonomous technology in future terms, it has already arrived,” Metal Shark’s CEO Chris Allard said in a statement. “Together with Sea Machines we’re bringing autonomy to market in a ready form that operators can buy today and run tomorrow.”

Through Sea Machines’ SM300 autonomous control and monitoring system, the Sharktech 29 Defiant and all onboard systems are commanded via a direct wireless PC-based user interface. An industrialized remote control with joystick provides manual control for situations when autonomy mode is not required, and an available belt-pack remote allows for vessel, systems and payload control within a one-to-two-kilometer range.

The system frees the operator from the helm to allow manned, technology-assisted control from anywhere onboard the vessel. Alternately, when unmanned operations are required, the vessel and its onboard systems may be monitored and controlled via network connections from a shoreside station or second vessel. Local situational awareness is provided to the remote operator via streaming video, ENC localization, radar, AIS and live environmental and deck machinery condition feeds. The vessel may also be operated autonomously in traditional (manned) mode.

Advanced mission planning and situational awareness capabilities round out the autonomous package. Routine software updates allow for system enhancements as additional refinements are made.

The advanced Sea Machines technology suite has been integrated into a versatile, military-proven hull form. Nearly 400 Metal Shark 29 Defiant vessels are in service worldwide. Powered by twin outboard engines, the vessel achieves top speeds in excess of 45 knots. The Sharktech 29 Defiant may be customized to suit unique mission requirements. However, to reduce lead times, a standardized configuration has been developed for the stock boats program.

“We founded Sharktech in 2018 to streamline the customer’s path to autonomy by bridging the gap between the industry’s autonomous software developers and the traditional shipbuilder,” said Allard. “Now, in conjunction with Sea Machines we have developed a turnkey autonomous production model to be kept in our regular stock rotation and available for near-immediate delivery.”

“The decision to partner with Metal Shark is yet another example of Sea Machines’ commitment to delivering advanced technology to the commercial marine market,” said Sea Machines’ founder and CEO Michael G. Johnson. “With our systems installed on board, commercial operators and government users alike will benefit from increased operational productivity and safety, and will gain capabilities such as force multiplication, collaborative vessel operations and remote payload control — all of which allows operators to do more with less.”
