Midwest Marine Group provides professional underwater ROV inspection services across the marine, offshore, ports, water, mining and infrastructure sectors.

Using remotely operated underwater vehicles equipped with high-resolution cameras and inspection technology, we can assess submerged assets without placing personnel in the water. ROV inspections provide a safe and efficient method of obtaining detailed visual evidence from difficult-to-access underwater environments while reducing reliance on divers, vessel downtime and operational disruption.

Our ROV capabilities include:

• Vessel hull, rudder and propeller inspections

• Sea chest, thruster and underwater appendage inspections

• Pre-purchase and condition surveys

• Damage investigations

• Underwater structures, piles and foundations

• Jetties, wharves and port infrastructure

• Moorings, chains and anchors

• Dams and reservoirs

• Water tanks and submerged infrastructure

• Intake and outfall structures

• Pipelines and submerged utilities

• Bridge piles and scour inspections

• Offshore and subsea infrastructure

• Search and recovery operations

• Environmental and seabed observations

Vessel & Marine Inspections

ROV technology allows vessel owners and operators to assess underwater hull condition without immediately requiring dry docking or diver mobilisation.

Inspections can document hull coatings, marine growth, corrosion, impact damage and the condition of propellers, rudders, shafts, thrusters, sea chests and other underwater appendages.

When incorporated into a broader marine survey, ROV findings can be assessed by our marine surveyors alongside above-water structural, machinery and operational condition.

Ports & Underwater Infrastructure

ROVs provide an effective method of inspecting submerged structures where access is difficult, hazardous or operationally disruptive.

MMG can inspect piles, quay walls, jetties, wharves, mooring systems, bridge foundations, intake structures, pipelines and other submerged infrastructure for visible deterioration, corrosion, damage, marine growth, displacement and other defects.

Dams, Reservoirs & Water Infrastructure

ROV inspections are particularly suited to confined or operational water assets where draining the structure or deploying divers may be impractical.

Applications include reservoirs, dams, water tanks, intake towers, gates, pipelines, culverts and other submerged infrastructure.

Digital Inspection & Reporting

ROV inspections can provide significantly more than live underwater video. Inspection data can be systematically recorded and referenced to identified components or areas of interest.

Depending on the project scope, deliverables may include high-resolution photographs, recorded video, defect observations, inspection logs and a detailed technical report identifying areas requiring maintenance, repair or further investigation.

Integrated Asset Integrity Solutions

A key advantage of Midwest Marine Group is our ability to combine underwater robotics with professional marine surveying and complementary inspection technologies.

Where required, ROV inspections can form part of a broader inspection program incorporating drone inspection, LiDAR and photogrammetry, ultrasonic thickness testing, visual testing, thermal imaging and other non-destructive testing methods.

This allows above-water, underwater and structural inspection information to be brought together to provide clients with a more complete understanding of asset condition.

Removing Risk with Robotics

ROV inspections reduce the requirement for personnel to enter hazardous underwater environments while providing asset owners with high-quality visual evidence and inspection data.

From a vessel hull inspection to a submerged port structure, reservoir or offshore asset, Midwest Marine Group provides practical underwater inspection solutions focused on safety, asset integrity and informed decision-making.
