Stinger’s Mini- and Micro-ROV are small and agile subsea vehicles, especially designed for demanding narrow areas and waters. Our innovative and automated solutions, high-end software, and fully electrical systems ensure a prompt and competent response to your needs, increased flexibility, operational continuity, better precision, and a substantial decrease in CO2 footprint.

Our drones

We deliver complete robotized solutions based on sophisticated in-house developed systems. Our drones can be permanently installed on the seabed, onboard oil production rigs, drilling rigs, anchor handlers and supply vessels. Stinger also provides services to support your drone operations in collaboration with you and our partners.

Our subsea drones can be mobilized quickly and efficiently, operated with resident or remote systems, and piloted in the field or from shore. They are specially designed to be small, powerful, and robust ensuring that they can handle the rough and demanding climate on the Norwegian Continental Shelf all year round and for longer periods of time.


The Stinger Mini-ROV is a powerful and portable ROV system, which can be equipped with multiple tools to perform a wide range of operations. It is designed to be deployed without a crane or lifting devices.

The Mini-ROV is equipped with eight 1.5kW thrusters, making it more than powerful enough to handle rough offshore conditions, 2×4 LED lights, and two high-resolution cameras as its standard setup. Optional equipment includes high-resolution multibeam sonar, positioning systems, gripper, CP-tools, and more.

A Stinger ROV pilot operates the Mini from a portable control station. The control station includes monitors for the ROV pilot and inspectors or client representatives. Video, sonar imagery, telemetry, and internal vehicle status can be monitored, recorded, stored, and streamed to an online inspector or client anywhere in the world.

The Stinger Micro ROV is an extremely agile and portable system suited to operations in confined spaces. It is designed to be deployed without a crane or lifting devices.

The Micro is equipped with eight thrusters giving it lots of power in six degrees of freedom. This means it is able to manoeuvre inside the most constricted spaces. It is integrated with a high-resolution camera and four powerful LED lights. Optional equipment includes high-resolution multibeam sonar, acoustic positioning, CP-probe, gripper and more.

A Stinger ROV pilot operates the Micro from a portable control station. The control station includes monitors for the ROV pilot and inspectors or client representatives. Video, sonar imagery, telemetry, and internal vehicle status can be monitored, recorded, and stored.

    Stinger Technology has an autonomous underwater vehicle (AUV) development program, which started as a collaboration with Neptune Energy, where we are developing a Mini-AUV with a similar form factor as our Mini-ROV (750x650x300mm). Small and lightweight vehicles provide the advantage of enabling precise inspection and monitoring of critical subsea assets while reducing the risk of equipment damage for clients. In contrast, traditional heavy duty vehicles pose unnecessary threats to vulnerable subsea infrastructure. Additionally, small drones can operate efficiently in areas with restricted access and the splash zone. They are also capable of fast and precise inspections of the vertical axis of a subsea structure. The lower unit cost of smaller AUVs allows for the deployment of multiple drones to maximize  operational efficiency.


    The Aquanaut AUV
    The Aquanaut from Nauticus Robotics is an AUV with inspection, intervention, and monitoring capabilities. The company is currently restructuring to focus their efforts on qualifying the Aquanaut in the Gulf of Mexico in collaboration with one of the major energy providers.


    The Sabertooth AUV
    The Sabertooth from Saab is a sophisticated AUV with stable baseline autonomous functionalities and compatibility with third party software and hardware.

    Stinger is qualifying a resident ROV system with Equinor at Tau Autonomy Center, where it completed a Client Acceptance Test in January 2024. The system has a subsea docking station with high battery capacity, a tether management system, acoustic sensors, cameras, lights, and other control systems. The system is remotely operated from Stinger’s own operational control centre at Stinger headquarters. System integration into infrastructure is highly flexible, making it easy to plug in to any underwater asset, from subsea docking stations to vessels and platforms. A modular “Internet of Things” design facilitates several third party sensors.

    The user case of the resident ROV system is to have continuous monitoring capabilities and instant access (visual and intervention) to a defined operational area. This can be harbors, subsea templates, wellheads, manifolds, Xmas trees, structures/platforms, umbilicals/risers, or critical segments of pipelines. The cost effectiveness of the system enables the installation of multiple systems across various locations. The resident system is unaffected by harsh weather conditions and well suited for remote areas.

    The original user case of the Resident-ROV was to monitor and aid the Sabertooth AUV. The Resident ROV was designed to function as an optical communication link to the larger drone, equipped with free space optics (FSO).

    In a realistic scenario, during critical phases of drone operations, such as docking, close inspection, and intervention on vulnerable infrastructure with a heavy duty AUV, the resident ROV system can facilitate a high bandwidth wireless connection (FSO) to the AUV as a contingency and safety measure. This will allow a person to intervene and control the AUV when needed. Inspecting the AUVs after or before longer missions might also be necessary to mitigate risk. For critical infrastructure, a permanent presence will also mitigate security risks related to non authorized human activities.

Remote in-field or onshore operations

With Stinger’s longstanding offshore experience and expertise, we’re able to deliver highly qualified personnel, groundbreaking technology, and superior communication systems making it possible to provide surveillance whilst operating in real-time. Coordinated and streamlined data collection with high-resolution footage provides the best possible foundation for efficient, precise, and safe decisions.

  • Advanced live streaming
  • Surveillance
  • Operations in real-time

Our fully or partly autonomous operations can be controlled directly in the field or from onshore control rooms providing better conditions for the safety of the personnel and the operation, the operational quality, and the environment. Stinger Technology will give you:

  • Increased flexibility and productivity

  • Cost-efficient operations, savings in logistics, crew, and execution, fewer vessel days, and shorter execution period

  • Advanced live streaming, surveillance, and operation in real-time

  • Easier access to the administration of data and a better foundation for analysis

  • Remote and autonomous control technology

  • Reduced CO2 emissions

Stinger holds long-term frame agreements with a number of major energy companies and acts as the operational entity, establishes operational procedures and routines, allocates trained personnel (operators, supervisors, inspectors, managers, etc.), and provides the remote control center, project management, and client management.

With this approach, Stinger Technology can provide a wide variety of underwater solutions, including large long-distance drones, small close-range drones, and other resident drone options. This technology, combined with our long operational experience, ensures a complete sustainable service.
