Hull & Structural Condition Assessment
The vessel's hull and accessible structural areas were examined for visible signs of corrosion, coating deterioration, deformation, wastage, previous repairs, and other condition indicators relevant to the acquisition assessment.
Deck areas and exposed structural members were also reviewed to identify conditions that could require future maintenance, steelwork, or closer examination.
Cargo System Assessment
The oil tanker cargo handling arrangements were reviewed as part of the technical assessment.
- Cargo piping arrangements
- Cargo pumps and associated equipment
- Valves and accessible cargo system components
- Cargo tank arrangements and accessible areas
- Deck cargo equipment
- Visible condition and maintenance indicators
The assessment focused on identifying visible deficiencies and maintenance considerations that could affect future operational reliability and expenditure.
Machinery Inspection
The main propulsion plant and auxiliary machinery were examined to evaluate visible condition, maintenance standards, operational indicators, and potential areas requiring further technical attention.
Main Propulsion
Assessment of accessible main propulsion machinery, visible condition indicators, maintenance presentation, and operational readiness.
Auxiliary Machinery
Review of auxiliary machinery, generators, pumps and supporting systems with attention to maintenance condition.
Engine Room Condition
Assessment of housekeeping, cleanliness, maintenance standards, visible leaks, deterioration, and general machinery space presentation.
Maintenance Indicators
Identification of visible wear, deferred maintenance indicators, repair requirements, and areas requiring future monitoring.
Safety & Compliance Review
Safety equipment and relevant technical documentation were reviewed to provide an overall indication of vessel readiness and compliance status within the agreed pre-purchase survey scope.
- Lifesaving appliances
- Firefighting equipment
- Emergency systems
- Navigation and communication equipment
- Statutory certificates
- Classification information
- Maintenance records
- Previous survey and repair records
Technical Documentation & Maintenance History
Available technical records were reviewed to assist in establishing the vessel's maintenance history and technical background.
Certification
Review of available statutory and classification certification relevant to the vessel's technical condition.
Maintenance Records
Review of available maintenance information and records to identify maintenance trends and outstanding requirements.
Survey History
Review of available previous survey, inspection, repair, and dry-docking information.
Technical Records
Assessment of available technical documentation supporting the vessel's operational and maintenance history.
Deliverables
The completed assignment provided the client with structured technical information to support the acquisition assessment.
- Pre-purchase survey report
- Technical deficiency register
- Repair and maintenance observations
- Technical risk assessment summary
- Photographic evidence where applicable
- Practical recommendations for further technical attention

Oil Tanker Pre-Purchase Survey FAQ
Why conduct a pre-purchase survey of an oil tanker?
A pre-purchase survey identifies structural, mechanical, operational, maintenance, and compliance risks before acquisition, helping buyers make informed investment decisions.
What areas of the tanker were inspected?
The inspection covered hull structure, deck machinery, cargo systems, engine room equipment, safety systems, and available onboard technical documentation.
What is technical due diligence?
Technical due diligence is an independent assessment of a vessel's condition, maintenance status, operational capability, technical risks, and potential future repair exposure before an acquisition decision.
Were cargo handling systems reviewed?
Yes. Cargo piping, pumps, valves, tank arrangements, deck equipment, and associated accessible components were assessed for visible condition and operational suitability within the agreed survey scope.
Why review vessel documentation?
Documentation reviews help verify statutory compliance, maintenance history, survey records, certifications, repair information, and other technical information relevant to the acquisition assessment.
