Underwater Inspection Project
Independent underwater inspection of a 55,000 DWT bulk carrier at Manila Anchorage following a change of vessel ownership and classification.
Project Overview
PAMS Pacific Admiralty Maritime Services conducted an underwater inspection project for a 55,000 DWT bulk carrier at Manila Anchorage in July 2026.
The inspection was undertaken following a change of vessel ownership and classification, providing the new stakeholders with an independent technical assessment of accessible underwater areas and associated vessel condition.
Project Background
The underwater inspection was arranged in connection with a change of vessel ownership and classification. In such circumstances, an independent technical assessment can provide useful condition information to the incoming stakeholders.
The inspection focused on accessible underwater areas and components within the agreed scope, with particular attention to the observable condition of the vessel's underwater hull and associated marine structures.
The assessment was conducted as an independent technical inspection and was intended to provide factual observations rather than replace the responsibilities of the vessel's classification society, Flag Administration, owner, operator, or other appointed parties.
Inspection Objectives
The principal objectives of the underwater inspection were to:
- Assess the observable condition of accessible underwater hull surfaces.
- Identify visible damage, deformation, coating deterioration, corrosion indications, marine growth, and other abnormalities.
- Examine accessible propeller and rudder areas.
- Examine accessible underwater appendages and fittings.
- Document relevant observations through inspection evidence where practical.
- Provide the new stakeholders with an independent technical condition overview.
- Identify areas requiring maintenance, monitoring, or further technical investigation.
Underwater Inspection Scope
The underwater examination covered accessible areas appropriate to the vessel and the agreed inspection requirements.
Underwater Hull
Visual examination of accessible hull surfaces for visible damage, deformation, coating condition, corrosion indications, marine growth, and other observable abnormalities.
Propeller
Examination of accessible propeller surfaces for visible damage, deformation, fouling, coating condition, and other observable abnormalities.
Rudder
Visual examination of accessible rudder surfaces and associated underwater areas for visible condition observations.
Appendages
Examination of accessible underwater appendages, fittings, bilge keel areas, and associated structures within the agreed inspection scope.
Sea Chests & Gratings
Visual examination of accessible sea chest areas and gratings for fouling, obstruction, damage, or other visible abnormalities.
General Underwater Condition
Overall assessment of the observable underwater condition, taking into account visibility, marine growth, access, water conditions, and inspection limitations.
Inspection Methodology
PAMS applied a structured underwater inspection methodology designed to provide traceable technical observations and condition information.
Pre-Inspection Review
Review of available vessel information, previous records, reported condition information, and the requirements applicable to the inspection assignment.
Inspection Planning
Establishment of the agreed underwater inspection scope, accessible areas, inspection sequence, evidence requirements, and reporting objectives.
Underwater Examination
Systematic visual examination of accessible submerged hull surfaces, propulsion components, steering components, appendages, fittings, and other agreed areas.
Evidence Collection
Photographic and video documentation was used where practical and technically suitable to support the recorded observations.
Technical Assessment
Observations were considered according to their apparent condition, location, significance, accessibility, and potential requirement for follow-up.
Reporting
Findings were documented in a structured technical format, distinguishing observed conditions from technical interpretation, limitations, and recommendations.
Technical Observation Categories
The underwater examination considered the following technical observation categories:
Hull Condition
Observable underwater hull condition, including visible damage, deformation, coating deterioration, corrosion indications, and other abnormalities.
Marine Growth
Marine growth and fouling were considered when evaluating visibility, accessibility, and the reliability of the underwater observations.
Propeller Condition
Accessible propeller areas were examined for visible damage, deformation, fouling, coating condition, or other observable abnormalities.
Rudder Condition
Accessible rudder surfaces and associated underwater areas were visually assessed for observable condition issues.
Technical Significance of Ownership & Class Change
A change of vessel ownership can require incoming stakeholders to establish an independent understanding of the vessel's present condition and outstanding technical matters.
A change of classification may also involve additional technical coordination and review requirements depending on the circumstances of the vessel and the receiving classification society.
Inspection Evidence & Documentation
Underwater inspection observations are most useful when supported by clear and traceable inspection evidence.
Photographic Evidence
Underwater photographs can document visible condition observations and provide a reference for subsequent technical review.
Video Evidence
Underwater video can provide broader visual context and assist with technical review of inspected areas.
Location Reference
Observations should be associated with identifiable vessel locations or components wherever practical.
Inspection Limitations
Visibility, marine growth, access, water conditions, and equipment limitations should be recorded where they affect the reliability or completeness of an observation.
Technical Condition Assessment
The inspection findings were considered within the context of the actual underwater inspection conditions and the agreed scope.
Observable Condition
Direct visual observations were recorded based on the areas that could be adequately accessed and viewed.
Technical Significance
Observations were considered according to their apparent significance and potential effect on maintenance or further technical investigation.
Follow-Up Requirements
Where an observation requires confirmation, measurement, cleaning, testing, repair, or further examination, appropriate follow-up can be recommended.
Independent Reporting
The assessment provides an independent technical record of the observed underwater condition within the agreed scope.
Project Value to the New Owners
The underwater inspection provided the incoming stakeholders with additional technical information concerning the vessel's observable underwater condition following the ownership and classification changes.
- Independent underwater condition information.
- Identification of visible underwater abnormalities.
- Documentation of accessible underwater areas.
- Technical evidence for maintenance planning.
- Identification of areas requiring further investigation.
- Additional technical information for vessel condition records.
Key Lessons from the Project
- Underwater inspection planning should reflect the vessel's specific condition and technical objectives.
- Areas affected by marine growth or restricted visibility should be clearly identified.
- Photographic and video evidence can improve technical traceability.
- Significant observations may require additional measurement or technical investigation.
- Findings should distinguish direct observations from technical interpretation.
- Underwater inspection results can provide useful supplementary information during ownership and classification transition.
