The MarinerSeadrone by Maritime Robotics

THE MARINER UNCREWED SURFACE VESSEL (USV) for coastal and open waters. Robust and effective, designed for precise data acquisition, environmental monitoring, and surveillance.

Boost operational
range and efficiency

Incorporate the Mariner USV into your fleet to expand your survey, monitor- ing, and exploration capabilities. Its dual-mode operation (autonomous and remote-controlled) ensures flexible deployment while reducing costs. For environmental monitoring or surveillance, the Mariner acts as a force multiplier, improving situational awareness, minimizing risk, and delivering results even in confined or offshore environments.

Custom payloads
for every mission

The Mariner is built to accommodate a wide array of sensors and sonars for precise, high-quality data collection. Thanks to its modular payload system (including moonpool elevators or fixed gondolas), you get optimal sensor placement and reduced interference. It’s the perfect platform for ROV support, seabed studies, and multi-sensor integrations tailored to your operational goals.

Durable, agile
and built for precision

Constructed with lightweight yet rugged polyethylene (PE) , the Mariner delivers high durability with low maintenance. Its shallow draft and waterjet propulsion allow for fine maneuverability in close-range or shallow environments. From coastal surveys to deepwater inspections, the Mariner is built to reach areas that traditional vessels cannot, both above and below the surface

Durable and versatile design

The Mariner USV is a dynamic, mid-size vessel designed for both remote-controlled and autonomous operations in coastal and offshore areas. The nearly unsinkable and maintenance-free construction made from polyethylene, provides a durable, stable and easily maintained USV.

Advanced maneuverability

Equipped with a combination of water jet propulsion and bow thrusters, the Mariner boasts exceptional maneuverability, crucial for precise operations and navigation in challenging environments. For additional operational reliability, the Mariner has optional redundant propulsion, ensuring safe and cost-efficient operations.

Transportability

Designed for convenience, the Mariner fits within a standard 40-foot container, along with all its spare and operational equipment. The Mariner can be deployed and recovered with a standard boat trailer or the optional custom made Launch and recovery (LARS) cradle. The LARS cradle safely captures and deploys the Mariner using an effective locking mechanism for securing the vessel.

Wide payload capacity

With a significant payload space featuring an optional retractable moonpool elevator, the Mariner facilitates seamless integration of both surface and subsurface sensors and payloads. The retractable moonpool elevator protects the sensors in its retracted position during transportation and launching of the vessel. Once the Mariner is ready for survey, the sensors are deployed on a gondola, outside the hull bubble slip-stream, ensuring optimal data quality.

Versatile operations

The Mariner provides a sustainable, safe and cost-effective solution for offshore and coastal surveillance and inspection, high-quality data acquisition, and environmental monitoring in diverse weather conditions and environments.

Equipped with radars, cameras, and sonars, the Mariner can detect and track different targets within an area. The high-bandwidth communication links enable seamless information transfer to shore stations or other vessels, making the Mariner a safe solution for accessing challenging areas, enhancing operational efficiency. Additionally, the Mariner can patrol and monitor pipelines, platforms, and wells using its onboard sensors. The vessel can also serve as a valuable support unit for Autonomous Underwater Vessels (AUVs), and act as a force multiplier for larger fleets.

For marine mapping and surveying, the Mariner is capable of collecting detailed seafloor and water-column data using sensors such as Singlebeam and Multibeam Echo Sounders, Sub-bottom Profilers, Sidescan Sonars and Sound Velocity Profilers. Additional sensors for environmental monitoring and fish-finding are also included in the versatile list of sensor integrations available. These sensors are tightly integrated with the vessel and the Autonomous Navigation System, offering an advanced interface with accessible and practical functionalities.
