Solution

Challenges

The aging of workboat crews is progressing, and the shortage of successors is becoming acute. Unstable working environments, hazards from waves and tidal currents, and heavy machinery operation on workboats—these represent a critical point that conventional management methods alone cannot resolve.
We solve challenges that exceed human limits at the site through teleoperation and automated technologies. This is a definitive path toward marine civil engineering sites that simultaneously achieve safety and productivity for the next generation.

ARAV Solutions

We promote DX at marine and dredging sites through teleoperation and automated solutions for construction machinery. Rather than DX for a single machine, we aim to provide a "Field Automation Platform" that optimizes the entire site operation.
For example, we are envisioning solutions such as the automated operation of backhoes (hydraulic excavators) on barges and soil-unloading machinery.
We contribute to improving safety across the entire site process and ensuring business continuity beyond individual tasks.

Target Processes for Teleoperation and Automation

Promoting Site DX Through Phased Implementation

Example Scenarios

Phase 1

Small Start - Demonstrate value starting with a single unit

Initially, we start with the teleoperation or automation of a single unit, such as a backhoe (hydraulic excavator) on a barge or a wheel loader for transport.
We select tasks where challenges are expected based on consultation and site requirements.
Based on the results from a single machine, we propose further DX promotion through future scalability and safety improvements.

Phase 2

Horizontal Expansion - Scaling to multiple units and proposing automation

After verifying practicality with a single machine, we propose the teleoperation or automation of subsequent units for specific work areas or sites.
[Examples of Machinery and Tasks]
Backhoes (Hydraulic Excavators) on Vessels: By teleoperating or automating dredging machinery, operators can be evacuated to onshore bases for safety even under the influence of waves or strong winds, while optimally and stably continuing excavation according to depth and soil quality.
Transport Vessels / Soil Unloading Sites:Teleoperating or automating multiple units involved in loading dredged soil onto barges and acceptance/transport at landing sites improves coordination accuracy, realizing efficient soil processing and shortened construction periods.

Phase 3

Final Phase

Our final vision is to further increase the number of teleoperated and automated machines to create unmanned operations and an environment free from constraints of time and location.
This contributes to improving the work environment at marine civil engineering sites, permanently avoiding natural environmental risks, and maintaining port functions through planned construction.
We aim for a site-wide DX that cannot be achieved by the automation of single machines alone.
