Pre-Purchase Vessel Survey & Technical Due Diligence
Independent technical inspection and condition assessment for vessel acquisition, investment decisions and maritime asset due diligence.
Technical Due Diligence for Maritime Assets
In the acquisition of maritime assets, incomplete technical data can create significant uncertainty. PAMS Pacific Admiralty Maritime Services provides impartial technical surveys designed to identify observable machinery defects, structural concerns, regulatory gaps, maintenance backlog risks and other technical conditions relevant to vessel acquisition.
The assessment is intended to provide practical technical information that can support asset-condition evaluation, repair exposure assessment, commercial discussions and informed investment decisions.
PAMS Pre-Purchase Survey Methodology
Machinery & Systems Assessment
Moving beyond external visual inspection by reviewing the condition and available records of propulsion, auxiliary machinery and power-generation systems.
Regulatory & Compliance Review
Review of applicable IMO, ISM, ISPS and MLC 2006 requirements together with class and statutory documentation to identify relevant compliance risks.
Maintenance History Validation
Review of PMS records, dry-dock history, maintenance records, outstanding defects and available technical documentation to identify potential future repair exposure.
Operational Readiness
Evaluation of vessel condition, documentation and operational preparedness against applicable industry expectations, including RightShip RISQ 3.2 and OCIMF SIRE 2.0 criteria where relevant.
Pre-Purchase Inspection Scope
The inspection scope is adapted to the vessel type, location, access arrangements and available technical documentation. Typical areas of assessment include the following.
Hull, Structural & Deck Integrity
- Visual screening of accessible ballast tanks, void spaces, cargo holds and exposed structures.
- Assessment for deformation, buckling, corrosion, localized pitting, coating breakdown and structural deterioration.
- Condition assessment of deck machinery, hydraulic mooring equipment, windlasses, winches and cargo containment systems.
- Hatch covers and sealing arrangements.
- Evaluation of corrosion control measures including sacrificial anodes and impressed current cathodic protection records where available.
- Review of thickness gauging reports, repair records, dry-dock history and structural maintenance documentation.
Machinery, Propulsion & Engineering Systems
- Main Engine and Auxiliary Engine condition assessment.
- Propulsion machinery operating records.
- Oil analysis data, oil mist detector history and crankcase inspection records where available.
- Fuel oil treatment systems.
- Air compressors, pumps, heat exchangers and cooling systems.
- Critical piping arrangements.
- Machinery automation, alarm history and safety protection devices.
- Planned Maintenance System records, outstanding defects and potential future repair expenditure.
Navigation, Communication & Safety
- Bridge navigation equipment.
- GMDSS functionality and available certification.
- Electronic Chart Display and Information System (ECDIS) certification and license validity.
- Navigation records and relevant documentation.
- Fire-Fighting Equipment (FFE).
- Life-Saving Appliances (LSA).
- Emergency systems and applicable SOLAS requirements.
Class, Statutory & Technical Records
- Classification survey status.
- Conditions of Class.
- Class recommendations.
- Statutory deficiencies.
- Enhanced Survey Programme (ESP) documentation where applicable.
- Thickness measurement reports.
- Survey status and available technical records.
Technical Documentation Review
Physical inspection findings should be considered together with the technical records available for review. Documentation can provide important context regarding vessel history, maintenance, class status and outstanding technical matters.
| Documentation Area | Technical Review Focus |
|---|---|
| Class Records | Survey status, Conditions of Class, recommendations, outstanding items and relevant technical history. |
| Dry-Dock History | Previous repairs, structural work, machinery work and recurring maintenance requirements. |
| PMS Records | Planned maintenance, overdue jobs, outstanding defects and maintenance trends. |
| Thickness Reports | Available structural thickness measurements and previously identified deterioration. |
| Statutory Records | Relevant certification, survey status and identified deficiencies. |
| Machinery Records | Operating history, available oil analysis, inspection records and relevant machinery maintenance information. |
Pre-Purchase Technical Assessment Process
Documentation Review
Review available class, statutory, maintenance, dry-dock, thickness and technical documentation before or during the inspection.
Physical Inspection
Examination of accessible structural areas, machinery, equipment, navigation, communication and safety systems within the agreed inspection scope.
Technical Cross-Check
Comparison of observed condition with available records, maintenance history, class status and technical documentation.
Risk Identification
Identification of observed defects, maintenance concerns, regulatory issues and technical conditions requiring further attention.
Decision Support
Findings are presented in a structured technical format to support vessel acquisition, repair planning and commercial technical discussions.
What the Survey Helps Determine
Repair Exposure
Identification of observed defects and conditions that may require repair, further investigation or technical follow-up.
Maintenance Backlog
Review of available maintenance information to identify outstanding work and potential future maintenance exposure.
Machinery Condition
Technical assessment of propulsion, auxiliary machinery, supporting systems and available operating and maintenance records.
Structural Condition
Identification of accessible structural deterioration, corrosion, deformation, coating breakdown and other observable conditions.
Class & Statutory Status
Review of available classification and statutory survey status, recommendations, conditions and deficiencies.
Technical Risk
Consolidation of relevant findings to provide a clearer technical understanding of the vessel's condition and acquisition risks.
Technical Survey Deliverables
Executive Summary
Immediate post-attendance technical briefing covering the principal findings identified during the inspection.
Full Technical Report
Detailed report with categorized findings, technical observations and supporting photographic evidence.
Risk Assessment
Practical identification of repair liabilities, maintenance concerns and priority technical findings.
Photographic Record
Condition evidence supporting technical findings, repair discussions and subsequent technical evaluation.
