Autonomous-Control and Advanced-Perception Systems

For Dredgers and Related Workboats
Available now, Sea Machines’ vessel intelligence systems install aboard existing or new-build dredges – including trailing suction hopper dredgers (TSHDs) and water injection dredgers (WIDs) – to increase their productivity and predictability, while reducing their overall risk and operational costs.

Capabilities & Use Cases

Autonomous Command

  Industry challenge: Highly manual operations
  Sea Machines solution: 
Technology that automates

Our systems automate tedious, redundant and dangerous tasks, and allows crewmembers to focus on higher-level operations via minimally manned or unmanned modes.

Operators can program vessels to autonomously deploy pre-established routes, a feature especially valuable for transiting to offshore sites. Workboats can be remotely commanded to follow paths in an unmanned or autonomous mode.

  Industry challenge: Systems lack intuitive and dynamic capabilities
  Sea Machines solution: 
Intelligent vessel systems

Unlike an auto-pilot, Sea Machines systems execute with human-like behavior, intelligently factoring in environmental and sea conditions (including wave height, pitch, heave and roll); change speeds between waypoints; and actively detect obstacles for collision avoidance purposes.

  Industry challenge: Operational incidents caused by fatigue
  Sea Machines solution: 
Obstacle detection and collision avoidance

Our systems help to reduce operator fatigue, a major casualty factor in marine incidents during nighttime operations, long-distance transfers and challenging sea states.

Remote Helm Operations

  Industry challenge: Vision obstruction that impairs operations
  Sea Machines solution: 
Remote helm control

Remote helm control ensures optimal visibility while docking, when maneuvering in tight quarters and during periods of low light, by allowing crews to command vessels from locations with the best vantage point, whether that be on or off the vessel.

The Sea Machines industrial-grade joystick offers portable helm operations, allowing mariners to command a vessel while monitoring operational indicators from a location outside of the wheelhouse.

  Industry challenge: Human exposure to challenging conditions
  Sea Machines solution: 
Minimally manned or unmanned operational modes

Sea Machines enables remote-helm, minimally manned or unmanned modes, which increases safety by eliminating or reducing the need for humans to be on board and exposed to challenging sea-states and dangerous environments.

  Industry challenge: Time-consuming and dangerous shift changes
  Sea Machines solution: 
Remote-operated, unmanned vessels

Remotely operated, unmanned vessels do not require stop-work periods for shift changes. This is especially important in poor sea and weather conditions, and through periods of low light or visibility.

Collaborative Autonomy

  Industry challenge: Inefficiencies related to large coverage areas
  Sea Machines solution: 
Autonomous vessel collaboration

Sea Machines systems enable vessels to autonomously collaborate as they follow pre-established grid patterns and perform other coordinated tasks.

To create a force-multiplier effect, operators can coordinate multiple autonomous boats to collaborate and follow the same paths at set distances apart, a feature especially useful for large coverage areas.

  Industry challenge: High-cost operations
  Sea Machines solution: 
Reduced crew requirements

Minimally manned and unmanned collaborative autonomous vessels reduce the resources required, helping to lower operational costs.

Grid Path Autonomy for Repetitive Routes

  Industry challenge: Operational incidents due to fatigue or distraction
  Sea Machines solution: 
Automation of repetitive or tedious vessel paths

The majority of operational incidents in the marine industry can be traced to human errors related to fatigue or distraction. Repetitive path autonomy eliminates the need for mariners to manually execute tedious paths, such as those used during site surveys and dredging operations.

  Industry challenge: Low performance and speed of manual operations
  Sea Machines solution: 
Autonomous grid paths

An autonomous vessel executes precision grid paths more predictably than a human operator.

Autonomous technology improve the speed and accuracy (XTE) of predefined and repetitive routes.

Remote Payload Control

  Industry challenge: Payload controls located in wheelhouse
  Sea Machines solution:
Remote payload control

Traditional payload controls are located inside a wheelhouse, requiring on-board operators to engage equipment from a location that doesn’t always offer the best vantage point. Sea Machines frees the operator to engage vessel payloads — such as cameras, pumps, sensors and other equipment — from anywhere on the vessel that offers the greatest visibility. Off-site operators can remotely activate and control on-board equipment from a distance of +/-1 kilometer.

Remote Vessel Monitoring

  Industry challenge: Limited visibility into real-time vessel operations
  Sea Machines solution: 
24/7 remote vessel monitoring

From a shoreside location or second vessel, Sea Machines enables operators to monitor the operations and progress of working vessels in real time, anywhere there is a network connection.

This “on-watch redundancy” can help to prevent operational incidents and keep crews safer.

Human operators can command and control fleets of unmanned vessels with greater efficiency and reduced operational cost.

Advanced Perception & Situational Awareness


  Industry challenge: Poor at-sea situational awareness
  Sea Machines solution:
Advanced perception and situational awareness technology

Slated for release in 2020, a future Sea Machines system will use Artificial Intelligence (A.I.) to improve at-sea situational awareness, object identification and tracking capabilities.

Using advanced sensors to collect a continuous stream of information from a vessel’s environmental surroundings, Sea Machines will identify and track potential conflicts, and efficiently display the data in the wheelhouse. This sensor fusion will provide a target’s name and flag, speed, course and more to an on-board or on-shore operator, enabling faster classification of the approaching object.

Proof of Performance

“In conjunction with Sea Machines, we have developed a turn-key autonomous production model to be kept in our regular stock rotation and available for near-immediate delivery. We’re bringing autonomy to market in a ready form that operators can buy today and run tomorrow.” — Chris Allard, Metal Shark

Sea Machines is now offering government customers a commercially available 29-foot autonomous vessel, made possible by Metal Shark’s “Sharktech” autonomous division. The system allows for traditionally manned, reduced-crew or unmanned autonomous operations to deliver “human-in-the-loop” navigation. Learn more.
