Ship Hull & Port Inspection by Coratia Technologies

Underwater robotics service

Ship Hull & Port Inspection

Ship and port underwater inspection uses ROV cameras, sonar, and survey tools to document hulls, propellers, rudders, quay walls, jetties, pilings, moorings, and navigational depth without relying only on diver access.

Overview

How the service supports asset decisions

Coratia supports vessel operators, ports, and marine engineering teams with inspection and survey data for submerged assets. Missions can focus on rapid visual checks, detailed condition records, sonar coverage, bathymetry, obstruction detection, or robotic cleaning, depending on the operational requirement.

Typical applications

  • Ship hull, propeller, rudder, sea chest, and appendage inspection
  • Quay walls, jetties, pilings, dolphins, and mooring structures
  • Berth pockets, approach channels, obstructions, and bathymetry
  • Marine growth assessment and configured robotic cleaning

Method

Inspection and survey workflow

  1. 01

    Operational planning

    Coordinate targets, vessel or berth status, access, traffic, visibility, and safety controls.

  2. 02

    Inspection setup

    Configure cameras, sonar, scaling, survey sensors, or cleaning tools for the task.

  3. 03

    Underwater mission

    Capture structured evidence across the agreed hull, structure, berth, or channel.

  4. 04

    Results package

    Deliver organized media, observations, and survey outputs for maintenance planning.

Outputs

Typical deliverables

  • Hull or structure video and still-image record
  • Observed fouling, damage, obstruction, or anomaly log
  • Sonar or bathymetric outputs where scoped
  • Inspection coverage and operating-condition summary

Direct answers

Frequently asked questions

What is underwater ship hull inspection?

Underwater ship hull inspection uses ROVs and specialized imaging or inspection equipment to examine submerged areas of a vessel without requiring the vessel to be dry-docked. It can help identify fouling, damage, corrosion, obstructions, and other underwater conditions.

Can an ROV inspect a ship while it is afloat?

Yes. ROVs can inspect vessels while they are afloat, subject to operational, environmental, and safety conditions. Inspections can cover areas such as the hull, propeller, rudder, sea chest, thrusters, and other submerged appendages.

What parts of a vessel can be inspected underwater?

Depending on the inspection scope, underwater vessel inspections can cover the ship hull, propeller, rudder, sea chest, thrusters, appendages, intake areas, and other submerged structures. The ROV configuration can be selected according to the vessel and inspection requirements.

Can ship hull inspections be performed in low-visibility water?

Yes. Low-visibility conditions can be supported using appropriate underwater imaging and sensing technologies. Imaging sonar can supplement cameras where turbidity or limited visibility affects the visual inspection range.

Can underwater vessel inspection and cleaning be performed together?

Yes. Inspection and cleaning can be combined when the ROV, tooling, surface conditions, environmental controls, and operational approvals are suitable for the required task. The appropriate approach depends on the vessel condition and mission requirements.

What information is provided after an underwater ship inspection?

Typical deliverables may include hull and structure video or still-image records, observations of fouling, damage, obstructions, or anomalies, sonar or bathymetric data where included in the scope, and an inspection summary documenting the inspected areas and operating conditions.
