Lesson 1 introduced independence as the profession's defining requirement. This lesson is where that principle gets tested in practice — because every survey-specific lesson ahead (Cargo, Hull & Machinery, Bunker, Draft, Marine Warranty) assumes you already understand exactly what a surveyor owes each party involved, and what happens when those obligations pull in different directions.
What You'll Learn in This Lesson
- The surveyor's primary responsibility, and why it doesn't change based on who's paying
- Who commissions marine surveys, and what each commissioning party actually needs
- The real difference between duty of care and duty to client
- What a surveyor is responsible for before, during, and after a survey
- How to recognise — and handle — a real conflict of interest
What Is the Surveyor's Primary Responsibility?
A marine surveyor's primary responsibility is to report what they actually find — accurately, completely, and regardless of which outcome would be more convenient for the party who commissioned the survey. Every other professional responsibility in this lesson exists to protect that one obligation. It's a deceptively simple standard that gets tested constantly in practice, because the party paying for a survey almost always has a preferred outcome in mind.
The Independence Principle: A Deeper Look
Independence isn't a personality trait some surveyors happen to have — it's a structural requirement of the role. A surveyor's report only has value to anyone, including the party who commissioned it, because other parties trust it wasn't shaped to favour whoever paid for it. The moment that trust breaks down, for one surveyor or the profession generally, every report becomes worth less — which is precisely why professional bodies like IIMS and NAMS treat independence violations so seriously.
In practice, independence means separating three things that are easy to conflate: who is paying the invoice, who the surveyor is professionally answerable to (in effect, the truth of what they find), and who will read and rely on the report. A surveyor commissioned by a P&I Club, for example, is being paid by the Club — but the report needs to hold up to scrutiny from the shipowner, the opposing party in a dispute, and potentially a court, not just satisfy whoever wrote the cheque.
Who Commissions a Marine Survey?
Different commissioning parties come to a survey with different, sometimes competing interests — understanding what each one actually needs is part of the job:
| Commissioning Party | What They Typically Need |
|---|---|
| Shipowners | Confirmation of a vessel's condition for insurance, sale, or chartering purposes |
| Charterers | An accurate handover record to avoid being liable for damage they didn't cause |
| P&I Clubs | An objective basis for assessing and defending third-party liability claims |
| H&M Insurers | An accurate risk picture before binding or renewing physical damage cover |
| Cargo Interests | Evidence of cargo condition at loading or discharge, to support or defend a claim |
| Banks / Buyers | An independent, defensible view of asset condition before completing a purchase or loan |
Notice that no party on this list is asking the surveyor to find a specific result — they're asking for an accurate one, even when they might privately hope for a favourable one. Confusing "what my client wants to hear" with "what my client actually needs" is one of the most common ways independence quietly erodes.

Duty of Care vs Duty to Client
| Dimension | Duty of Care | Duty to Client |
|---|---|---|
| What It Means | Conducting a thorough, competent inspection and reporting findings accurately | Delivering the report professionally, on time, and within the agreed scope |
| Who It Protects | Everyone who relies on the report's accuracy — including parties who didn't commission it | The commissioning party's legitimate procedural interests |
| Can It Be Waived? | No — this is the non-negotiable core of the profession | Partially — scope, timeline, and format can be agreed with the client |
| What It Never Includes | Shaping findings to favour the client's preferred outcome | Withholding relevant findings the client would rather not see |
The two duties usually align — a client who commissions a survey generally does want an accurate report. The tension only becomes visible when the accurate finding is one the client didn't want, and that's exactly the moment duty of care has to take priority.
Professional Responsibilities Throughout a Survey
Before the survey: confirming scope and instructions in writing, disclosing any potential conflict of interest up front, and preparing the right equipment and reference standards for the specific survey type. During the survey: recording objective evidence as it's found (not reconstructed from memory afterward), photographing conditions before they can change, and noting anything outside the original scope that still affects the findings. After the survey: writing the report to reflect exactly what was found, retaining supporting evidence in case the report is later challenged, and being willing to defend the findings under questioning — including from the party who commissioned the work.
Common Conflicts of Interest
- A surveyor with a financial relationship to the commissioning party beyond the survey fee itself
- Repeat business pressure — softening a finding to protect a valuable ongoing client relationship
- A surveyor asked to review work they were previously involved in producing (auditing their own prior recommendation)
- Time or cost pressure from the client that would require skipping a genuinely necessary inspection step
None of these automatically disqualify a surveyor from the work — but every one of them needs to be disclosed and managed, not quietly absorbed into how the survey is conducted.
Case Study: Pressure From a Client to Modify Findings
Scenario: A pre-purchase survey finds significant corrosion in a ballast tank. The prospective buyer, who commissioned the survey, asks the surveyor to describe the finding as "minor surface rust" instead, to avoid complicating the sale.
This is exactly the moment where duty of care and duty to client can appear to conflict — and exactly the moment the industry relies on the surveyor to resolve that conflict the same way, every time.
Exercise: Is the Surveyor Acting Independently?
Read each scenario and decide.
1. A surveyor discloses to both parties that they've previously done unrelated work for the commissioning shipowner, then proceeds with the survey.
2. A surveyor softens a finding after the client mentions they're a major repeat customer.
3. A surveyor writes the same finding they would have written regardless of who commissioned the survey.
4. A surveyor skips a required inspection step because the client is in a hurry and doesn't want to pay for the extra time.
Best Practices Checklist
- Scope and instructions confirmed in writing before the survey begins
- Any potential conflict of interest disclosed to all relevant parties up front
- Objective evidence recorded at the time it's found, not reconstructed afterward
- Findings written exactly as observed, regardless of client preference
- Supporting evidence retained in case the report is later challenged
- Willingness confirmed to defend findings under questioning from any party

Frequently Asked Questions
Can a marine surveyor work for the shipowner?
Yes — shipowners are one of the most common commissioning parties. The surveyor's obligation to report objectively applies regardless of which party is paying.
What is surveyor independence?
The professional obligation to report findings accurately and objectively, regardless of who commissioned the survey or what outcome they might prefer.
Who pays a marine surveyor?
Whoever commissions the survey — a shipowner, charterer, P&I Club, insurer, cargo interest, or buyer — but payment doesn't change the surveyor's obligation to report objectively.
Can a surveyor be held liable?
Yes — a surveyor can be held professionally and legally liable for a negligent or inaccurate survey, which is part of why retaining supporting evidence matters.
What happens if a survey report is biased?
A biased report undermines the surveyor's professional credibility, can expose them to liability, and damages trust in their reports going forward — for that surveyor and, over time, the profession generally.
