Know What's Happening Below the Waterline Before It Costs You Time and Money

The most costly underwater problems are often the ones you can't see. Hull fouling, propeller damage, corrosion, coating failure, and marine growth can reduce vessel performance, increase fuel consumption, delay maintenance plans, and lead to unexpected repairs.

Qualitech Marine provides professional underwater inspection, hull cleaning, and technical reporting that give technical superintendents, fleet managers, and vessel owners the evidence needed to make faster, smarter maintenance decisions—with confidence.

See the condition clearly. Reduce operational risk. Make the right decision.

COMMON ISSUES WE SOLVE

Is Your Vessel Facing Any of These Underwater Problems?

Early underwater verification helps prevent unnecessary downtime, reduce operational risk, and support informed maintenance decisions.

Hull Fouling Is Reducing Vessel Performance

Marine growth on the hull and propeller can increase fuel consumption, reduce vessel speed, and affect propulsion efficiency long before the problem is visible above the waterline.

Our solution

We inspect the underwater condition, assess the extent of marine growth, and carry out hull cleaning or propeller polishing where operationally appropriate.

Suspected Underwater Damage After Contact or Grounding

Berthing contact, floating debris, tug operations, or grounding may cause underwater damage that cannot be confirmed through a visual inspection from deck.

Our solution

Our commercial divers verify the affected area and provide photographs, video, and condition reports to support informed repair and operational decisions.

Underwater Obstructions Affecting Safe Operations

Ropes, fishing nets, debris, or marine growth can interfere with propellers, rudders, sea chests, and other underwater appendages, affecting vessel performance and operational reliability.

Our solution

We identify the obstruction, verify the underwater condition, and recommend or perform the appropriate corrective action whenever operationally feasible.

Address Hull Fouling Before It Further Affects Performance

Marine growth on the hull and propeller can increase resistance, reduce propulsion efficiency, and contribute to higher fuel consumption. We verify the underwater condition and determine whether inspection, cleaning, or propeller polishing is appropriate based on the vessel’s condition and operational feasibility.

✓ Underwater hull and propeller inspection
✓ Marine-growth condition assessment
✓ Hull cleaning or propeller polishing, where suitable
✓ Underwater photo and video documentation

— OUR UNDERWATER SERVICES —

Confirm Suspected Underwater Damage While the Vessel Is Afloat

Grounding, berth contact, tug interaction, or floating debris may cause damage below the waterline that cannot be assessed from deck. Our divers inspect the reported area and document the findings to support repair planning, operational decisions, and further technical review.

✓ Targeted inspection of the reported area
✓ Examination of related underwater components
✓ Underwater photographs and video
✓ Condition findings and inspection report

Confirm Suspected Underwater Damage While the Vessel Is Afloat

Ropes, fishing nets, debris, and marine growth may interfere with the propeller, rudder, sea chest, or other underwater appendages. We verify the location and extent of the obstruction and carry out removal or recommend the appropriate next action when conditions permit.

✓ Propeller and rudder inspection
✓ Sea chest and grating inspection
✓ Rope, net, or debris removal where feasible
✓ Post-work verification and documentation

Need Help Choosing the Right Underwater Service?

Send us the vessel’s concern, port, and schedule. We’ll review the requirement and help define the appropriate scope and next step.

Frequently asked questions

1. Can underwater work be carried out while the vessel is afloat?

Yes. Many underwater inspections, cleaning tasks, and condition checks can be completed while the vessel remains afloat.

Feasibility depends on the vessel’s condition, location, schedule, working environment, port requirements, and the proposed scope. Send us the vessel details so we can review the practical arrangement.

4. Can you support suspected damage or urgent underwater problems?

Yes. We can review requirements involving suspected grounding or contact damage, entanglement, obstruction, blocked sea chests, and other visible underwater abnormalities.

For urgent cases, include the vessel’s location, ETA, available working window, photographs if available, and the deadline for the technical decision.

2. What underwater services can Qualitech Marine arrange?

Depending on the vessel’s requirement, services may include:

• underwater inspection and visual assessment;

• hull and propeller cleaning;

• propeller polishing;

• rope, net, and debris removal;

• suspected damage inspection;

• sea chest and underwater-opening checks;

• pre-dry-dock condition inspection; and

• underwater photo and video documentation.

Cleaning and polishing are arranged only where permitted by applicable port and environmental requirements. The final scope is based on the vessel’s actual condition and operational need.

5. How quickly can your team mobilize?

Mobilization depends on the vessel’s location, service scope, working window, personnel and equipment availability, port access, weather, water conditions, and local requirements.

Once we receive the vessel details, we can review feasibility and advise the earliest practical arrangement.

3. What information should we send for an initial review?

Please send:

• vessel name and type;

• port, anchorage, or operating location;

• ETA, ETD, and available working window;

• underwater concern or required service; and

• local agent details, where available.

Photographs, drawings, previous reports, and reporting requirements are helpful but may be sent later. You do not need every detail before contacting us.

6. What photographs, video, and reporting will we receive?

Reporting is agreed before the job and may include:

• underwater photographs and video;

• location-specific observations;

• visible defects or abnormalities;

• before-and-after evidence;

• work-completion details; and

• a completion summary.

The report provides organized evidence to support your technical team’s next decision.

Unless specifically included and performed through the appropriate approved parties, the service report does not constitute a class or statutory survey.

7. How is the quotation prepared?

We review the vessel requirement, location, schedule, scope, deliverables, and working conditions before issuing the quotation.

This helps ensure the proposed scope is practical, clearly defined, and less likely to require avoidable changes after mobilization.

8. Which Philippine locations do you cover?

We support selected Philippine ports, anchorages, and coastal locations, subject to local access and operational feasibility.

Send us the vessel’s location and schedule so we can confirm availability and the practical mobilization arrangement.
