Marine surveying is one of the most technically demanding and commercially important professions in the shipping industry. Yet for many ship owners, cargo interests, and insurers — particularly those new to shipping — the scope and purpose of marine surveys is not always clear. This guide covers the essentials.
What is a Marine Survey?
A marine survey is an independent, professional inspection of a vessel, its cargo, or related marine property. The survey is conducted by a qualified marine surveyor who provides an objective assessment and a formal written report. That report serves as documentary evidence for insurance purposes, commercial transactions, legal proceedings, or regulatory compliance.
The key word is independent. A marine surveyor works for the party that engages them — not for the carrier, the port, or any other interested party. This independence is what gives survey reports their commercial and legal credibility.
Types of Marine Surveys
The marine survey industry covers a wide range of specialisations. The main categories relevant to commercial shipping in Singapore include:
- Condition surveys — assess the general condition of a vessel at a specific point in time, often for insurance or pre-purchase purposes
- Cargo surveys — verify the condition and quantity of cargo at loading, discharge, or during storage
- Bunker surveys — measure and document fuel oil quantity and quality during bunkering operations
- Draft surveys — determine cargo weight by measuring the vessel's displacement before and after loading or discharge
- On-hire and off-hire surveys — document a vessel's condition at the start and end of a charter period
- Damage surveys — investigate and document damage to a vessel or cargo following an incident
- P&I surveys — conducted on behalf of Protection and Indemnity clubs following incidents involving personal injury, pollution, or cargo claims
How Survey Reports Are Used
A well-written survey report is one of the most commercially useful documents in shipping. Its primary uses include:
📋 Insurance Claims
Underwriters rely on independent survey reports to assess the validity and quantum of claims. A report from an MPA-licensed surveyor accepted by the insurer is the fastest path to claim resolution.

MPA Licensing and Why It Matters
Singapore Marine Agency is licensed by the Maritime and Port Authority of Singapore (MPA) to conduct marine surveys at all ports and anchorages of Singapore. MPA licensing is not merely administrative — it signifies that the agency and its surveyors meet the standards required by Singapore's maritime regulator.
Reports from MPA-licensed surveyors are accepted by all major P&I clubs, marine underwriters, classification societies, and maritime authorities worldwide. When selecting a surveyor in Singapore, MPA licensing should be a baseline requirement.
Choosing the Right Marine Surveyor in Singapore
Singapore has many marine survey companies. When evaluating your options, the key criteria are: MPA licensing, the specific expertise required for your survey type, response time capability, and the quality and format of reports produced. References from P&I clubs and insurers who have accepted the surveyor's reports previously are a reliable indicator of quality.
