The Need for Better Hull Inspection
Hull inspection is a critical part of vessel maintenance and offshore asset management. Operators need reliable information about coating condition, structural integrity, and potential corrosion.
Traditionally, these inspections are performed by divers or manual teams, often under time pressure and in challenging conditions. Visibility, accessibility, and safety constraints can limit the quality and consistency of the inspection.
As offshore operations become more demanding, there is a growing need for more controlled and repeatable inspection methods.
Limitations of Traditional Inspection Methods
Conventional hull inspection approaches present several challenges:
- Dependence on diver availability and conditions
- Limited visibility in underwater environments
- Inconsistent documentation and repeatability
- Safety risks associated with underwater work
In addition, combining inspection with other tasks, such as cleaning, often requires separate operations, increasing cost and downtime.
How Robotic Hull Inspection Works
Robotic hull inspection uses a crawler-based system that can be equipped with inspection tools such as cameras or measurement devices.
In most operations, the operator remains on deck or on a stable working area with direct line-of-sight to the robot when operating above water. For underwater operations, monitoring is typically supported by cameras integrated into the system.
The crawler is controlled via cable, allowing precise positioning and stable movement across the hull surface.
Using magnetic adhesion, the crawler maintains contact with the underlying steel structure. This enables movement across vertical and inclined surfaces, even when coatings or marine growth are present.
Inspection and Measurement Capabilities
Depending on the tool configuration, a crawler platform can support:
- Visual inspection of hull surfaces
- Coating condition assessment
- Identification of damage or irregularities
- Localised measurements, such as thickness or corrosion checks
The ability to position sensors accurately and maintain stable contact improves the reliability of collected data.
Combining Cleaning and Inspection
One of the key advantages of a modular crawler platform is the ability to combine tasks.
Cleaning and inspection can be performed using the same system by changing or combining tools. This allows operators to:
- Clean a surface and inspect it immediately afterwards
- Focus inspection on areas of interest identified during cleaning
- Reduce the need for multiple mobilisations
This integrated approach improves efficiency and reduces operational complexity.
Benefits for Service Providers and Operators
- Improved Safety
Reduced reliance on divers for certain inspection tasks. - Better Data Quality
Stable positioning and controlled movement improve inspection consistency. - Increased Efficiency
Cleaning and inspection can be combined in a single workflow. - Operational Flexibility
The same platform can be used across multiple vessels and applications.
Designed for Real Offshore Conditions
Hull inspection environments are dynamic and often unpredictable. Waves, currents, and limited visibility all impact operations.
Crawler-based systems are designed to operate under these conditions, maintaining stable contact with steel surfaces and enabling controlled movement even in challenging environments.
Expanding the Role of Robotic Systems
Hull inspection and measurement represent a natural extension of crawler-based robotics.
By enabling both cleaning and inspection on the same platform, robotic systems become more than a single-purpose tool. They support a broader range of maintenance and engineering tasks.
