LNG Pre-Purchase Inspection & Technical Due Diligence
Independent technical inspection and pre-purchase assessment of an LNG carrier to support vessel acquisition decisions, identify technical risks, evaluate vessel condition, and establish a clear technical basis for commercial and investment due diligence.
LNG Pre-Purchase Inspection Project
PAMS Pacific Admiralty Maritime Services provides independent marine technical consultancy for LNG carrier pre-purchase inspections and technical due diligence.
The inspection is intended to provide the prospective buyer with an independent assessment of the vessel's apparent technical condition, machinery, cargo containment and handling systems, marine systems, safety equipment, documentation, maintenance status, and identified technical risks.
Asset Type
Liquefied Natural Gas (LNG) Carrier
Service
Pre-Purchase Inspection & Technical Due Diligence
Technical Focus
Hull, machinery, cargo systems, LNG containment, safety systems, maintenance, documentation, and operational condition.
Inspection Objective
Identify material technical risks and provide independent information supporting the buyer's acquisition decision.
Client Requirement
The prospective buyer required an independent technical inspection of an LNG carrier under consideration for acquisition.
The objective was to establish an independent understanding of the vessel's apparent condition and identify technical matters that could affect vessel value, operational reliability, safety, maintenance requirements, dry-docking expenditure, regulatory compliance, or future capital expenditure.
Particular attention was given to the specialised systems associated with LNG transportation, including cargo containment, cargo handling, gas-related systems, propulsion and machinery, safety systems, and the vessel's maintenance and inspection history.

LNG Pre-Purchase Inspection FAQ
What is an LNG pre-purchase inspection?
An LNG pre-purchase inspection is an independent technical assessment of an LNG carrier performed before acquisition to identify apparent vessel condition, technical deficiencies, maintenance concerns, documentation issues, and potential future expenditure.
Why is a pre-purchase inspection important for an LNG carrier?
LNG carriers contain specialised cargo containment, cargo-handling, gas-related, propulsion, and safety systems. An independent inspection can help the prospective buyer identify technical risks before completing an acquisition.
What systems are inspected on an LNG carrier?
Depending on the agreed scope, the inspection may cover hull and structural condition, propulsion, auxiliary machinery, electrical systems, LNG cargo containment and handling systems, deck equipment, navigation equipment, safety systems, firefighting equipment, life-saving appliances, and other marine systems.
Is the LNG cargo containment system included?
LNG cargo containment systems form an important part of the technical assessment. The scope may include visual inspection of accessible areas, review of available records, identification of observable defects, and recommendations for specialist examination where required.
Are cargo pumps and compressors inspected?
Yes, where included within the agreed inspection scope. Their apparent condition, maintenance status, operating information, records, and identified technical concerns may be reviewed.
Are class and statutory records reviewed?
Available class and statutory documentation can be reviewed as part of technical due diligence, including survey status, recommendations, conditions, certificates, and other relevant records made available for inspection.
Does the inspection identify future repair expenditure?
The inspection can identify apparent defects, deterioration, overdue maintenance, equipment concerns, and other matters that may indicate future repair, renewal, dry-docking, or capital expenditure requirements. Detailed cost estimation requires appropriate repair specifications and commercial quotations.
Can the inspection include machinery condition assessment?
Yes. Main propulsion, auxiliary machinery, electrical generation, pumps, compressors, and other relevant equipment can be assessed within the agreed technical scope, together with available maintenance and operational records.
Is the inspection a classification survey?
No. A pre-purchase inspection is an independent technical consultancy and condition assessment. It does not replace surveys or inspections performed by a classification society, Flag Administration, or statutory authority.
What does the buyer receive after the inspection?
The buyer receives a structured technical report covering the agreed inspection scope, observations, identified deficiencies, technical concerns, documentation findings, and recommendations for further investigation or action.
Can PAMS provide LNG condition inspections after acquisition?
Yes. Independent LNG condition inspection and technical consultancy can also be provided after acquisition to establish vessel condition, support maintenance planning, identify technical deficiencies, or assist with specific technical due diligence requirements.

LNG Pre-Purchase Project Reference Notice
The information presented on this project page describes the methodology and technical scope applicable to LNG carrier pre-purchase inspection and technical due diligence assignments. Actual inspection scope depends on vessel type, age, cargo containment system, propulsion arrangement, trading history, location, access, available documentation, classification status, buyer requirements, and the agreed technical scope. Findings from a pre-purchase inspection are based on accessible areas, available information, visual observations, operational evidence, and agreed inspection activities and should not be interpreted as a substitute for specialist testing, statutory surveys, classification surveys, or destructive examination where such examination is required.
