Maritime Interview Masterclass: How to Nail Your Shipping Company Interview

You have 15 years of sea time. Your certificates are current. Your discharge book is clean. And you just got rejected after a 20-minute Teams call with a manning agency recruiter who’s never been to sea.

It happens constantly. The maritime industry has an interview problem — experienced professionals who can handle a Force 10 storm but freeze when asked “Tell me about a time you resolved a conflict on board.”

Here’s the truth: maritime interviews are not about checking if you can do the job. Your CoC, sea service, and certificates already prove that. Interviews are about three things:

1. Will you fit the crew? Personality, communication, attitude under pressure.
2. Do you actually know your systems? Not textbook answers — real operational knowledge.
3. Are you a liability? Safety awareness, compliance understanding, incident history.

This guide covers real interview questions by sector — tankers, gas carriers, DP vessels, offshore, survey, ROV, HSE, oil & gas, and wind energy. No generic “what is your greatest weakness” nonsense. Actual questions that actual interviewers ask, with guidance on what they’re really looking for.

📋 Before We Start: The Universal Rules

These apply regardless of sector, rank, or interview format.

Online vs. In-Person: What Changes

Online (Teams / Zoom / WhatsApp video):

• Test your connection 30 minutes before. Not 5 minutes. Thirty.
• Camera on, good lighting, plain background. No ship cabin with laundry hanging behind you.
• Have your certificates, discharge book, and CV open on screen or printed next to you.
• Look at the camera, not the screen. This is the single most common mistake.
• If your connection drops — don’t panic. Rejoin, apologise briefly, continue.

In-person (manning agency office / company HQ):

• Arrive 15 minutes early. Not 30, not 5. Fifteen.
• Dress code: business casual minimum. A polo shirt is fine. A stained hoodie is not.
• Bring originals of all certificates plus one printed copy of your CV.
• Firm handshake, eye contact, phone on silent. The basics matter.

Who’s on the Other Side of the Call

Most candidates expect one interviewer. In reality, maritime interviews often involve 2 people on the call — sometimes 3. Here’s the typical setup:

The Crewing Manager asks about:

• Your availability, documents, certificate validity
• Contract preferences, rotation expectations, salary range
• Career history, gaps in sea service, reasons for leaving previous companies
• Soft skills: communication, adaptability, motivation

The Superintendent (or Technical Manager) asks about:

• Your actual technical knowledge — vessel systems, cargo operations, DP, machinery
• Scenario-based questions: “What would you do if…”
• Real-life situations you’ve handled — emergencies, equipment failures, near-misses
• Your understanding of the specific vessel type and operation

Sometimes a third person joins — an Operations Manager, HSE Manager, or client representative (especially in offshore). They typically observe and ask 2–3 targeted questions.

The STAR Method — Learn It

Most behavioural questions in maritime interviews follow the STAR format:

• Situation — Set the scene. Vessel type, location, conditions.
• Task — What was your specific responsibility?
• Action — What did YOU do? Not “we” — you.
• Result — What was the outcome? What did you learn?

“Tell me about a time you dealt with an emergency on board.”

S: “On a DP2 construction vessel in the North Sea, we experienced a total blackout during a pipe-lay operation.”

T: “As the Second Officer on DP watch, I was responsible for maintaining vessel position and coordinating with the bridge team.”

A: “I immediately initiated the DP emergency procedure — switched to independent joystick mode while the generators were being restored, communicated with the construction team to halt operations, and notified the vessel traffic service.”

R: “Power was restored within 4 minutes. No position excursion exceeded the yellow alert threshold. The client commended the crew’s response. I documented the incident and contributed to the updated DP FMEA review.”

That answer takes 40 seconds. It tells the interviewer everything they need — competence, composure, communication, and follow-through.

What Interviewers Actually Write Down

Category	What they’re checking
Technical knowledge	Do you know your systems, regulations, and procedures?
Safety awareness	Do you think in terms of risk, or do you wing it?
Communication	Can you explain things clearly? Will you speak up when something’s wrong?
Teamwork	Will you get along with the crew? Can you take direction? Give direction?
Problem-solving	How do you react when things go wrong?
Motivation	Why this company, this vessel, this rotation? Or are you just applying everywhere?
Red flags	Gaps in service, attitude issues, vague answers, blaming others

How to Handle Gaps in Sea Service

This comes up in almost every interview. Recruiters notice gaps. Don’t try to hide them — explain them.

---

🔴 Red Flags That Instantly Kill Your Application

1. Badmouthing previous employers or crew. “The Master was an idiot” = you’ll say the same about us.
2. Vague technical answers. If you can’t explain basic watchkeeping procedures for your rank, the interview is over.
3. Zero questions for the interviewer. You should have at least 2–3 prepared.
4. Salary as the first question. Ask about the vessel, the operation, the rotation — not the money.
5. Inconsistent stories. If your CV says one thing and your interview says another, trust is gone.
6. Certificate awareness. Not knowing your own certificate expiry dates screams disorganisation.
7. Phone ringing during the interview. In 2026, this still happens. Don’t be that person.

Questions YOU Should Ask the Interviewer

• “What is the typical crew rotation schedule?”
• “What flag is the vessel? Which class society?”
• “What DP system is installed?” (for DP roles)
• “What is the client’s HSE reporting culture like?”
• “How does the company handle certificate renewals and training?”
• “What is the joining process — flights, PPE, medical requirements?”
• “Is there a structured handover period on board?”
• “What happened with the previous person in this role?” (Use carefully — but very informative)

⛽ Tanker Fleet (Oil & Chemical Tankers)

Tanker interviews are heavy on cargo operations, safety systems, and regulatory compliance. Interviewers want to know you won’t blow up their ship. That’s not an exaggeration — the consequences of incompetence on tankers are catastrophic.

Deck Officers (OOW → Master)

Cargo operations — these WILL be asked:

• “Walk me through a crude oil loading operation from start to finish.” — They want: pre-loading checks, valve lineup, communication with terminal, monitoring ullages, topping-off procedure, documentation. YOUR procedure, not a textbook.
• “How do you calculate tank stresses during loading? What’s your SWBM limit?” — Know your vessel’s loading computer. Mention the specific system (CargoMax, etc.).
• “Explain the IGS system on your last vessel. What was the IG pressure maintained at during discharge?” — Typical: 100–150 mmWG. Follow-up: “What if the IG plant fails mid-discharge?”
• “What is the purpose of COW? When do you perform it?” — Crude Oil Washing procedure, MARPOL requirements, which tanks, what sequence.
• “Describe your vessel’s PV valve system. What are the settings?” — Typically +2000 mmWG / -700 mmWG for crude carriers.

SIRE / CDI inspection questions:

• “Have you been through a SIRE inspection? What was your role?” — Know the VIQ (Vessel Inspection Questionnaire) structure.
• “What are the key OCIMF publications you follow?” — ISGOTT, OCIMF mooring guidelines, CDI standards for chemical tankers.
• “How do you prepare for a vetting inspection?” — Pre-inspection checklist, crew familiarisation, documentation review, deck walkthrough.

Safety-critical scenarios:

• “You detect H2S during cargo operations. What’s your immediate action?” — Emergency alarm, muster, stop all operations, upwind assembly, casualties assessment, notify terminal. Step by step.
• “Cargo tank pressure is rising beyond PV valve capacity. What do you do?” — Reduce loading rate, check IG system, verify venting, worst case — stop loading.
• “A crew member collapses in the pump room. What’s your procedure?” — Enclosed space rescue protocol. NOT “I go in to help him.” That answer gets people killed and fails interviews.

Engineers on Tankers

• “Describe the cargo pump system on your last vessel. Centrifugal or deepwell?”
• “How do you maintain the IGS — scrubber, deck seal, regulation valve?”
• “What was the last cargo pump overhaul you supervised?”
• “Explain the COW system from an engineering perspective — what maintenance is critical?”
• “How do you handle a cargo pump seizure during discharge?”

---

🧊 Gas Carriers (LNG / LPG)

Gas carrier interviews are among the most technical in the maritime industry. The cargo systems are complex, the consequences of errors are severe, and the companies hiring are usually major operators who can afford to be selective.

Deck Officers

Core cargo knowledge — non-negotiable:

• “Explain the reliquefaction process on your LNG carrier.” — Moss-type, membrane GTT Mark III/No. 96, IHI SPB. Know YOUR vessel’s system in detail.
• “What is boil-off gas (BOG) and how is your vessel configured to handle it?” — BOG rate, GCU, reliquefaction plant, dual-fuel engine consumption. Quantify it.
• “Describe the cool-down procedure before loading LNG.” — Inerting → gassing up → cool-down. Cooldown rates, stress monitoring, temperature differentials.
• “What is rollover in an LNG tank, and how do you prevent it?” — Density stratification → sudden mixing → rapid boil-off → pressure spike. This separates theory from experience.
• “What is the critical temperature of methane? Why does it matter?” — -82.6°C. Determines your entire cargo containment philosophy.
• “Explain the ESD sequence during LNG transfer.” — Manual ESD, automatic triggers, valve closure sequence, communication protocol.

LPG-specific questions:

• “Difference between fully refrigerated, semi-refrigerated, and fully pressurised LPG carriers?”
• “Your LPG cargo temperature is rising above target. Walk me through the troubleshooting.”
• “How do you handle a propane/butane incompatibility issue when loading multi-grade cargo?”

Engineers on Gas Carriers

• “How does dual-fuel operation work on your engine? ME-GI or X-DF?” — MAN ME-GI (high-pressure) vs. WinGD X-DF (low-pressure, Otto cycle). Fundamentally different systems.
• “What is the gas detection system configuration on your vessel?”
• “Explain the nitrogen generator system and its role in cargo operations.” — PSA vs. membrane type.

🎯 DP Vessels (Dynamic Positioning)

DP interviews are among the most structured in the industry. The Nautical Institute certification scheme means there’s a clear standard — and interviewers test against it.

DPOs (Dynamic Positioning Operators)

Core DP knowledge — you WILL be tested:

• “Explain the difference between DP Class 1, 2, and 3.” — Class 1: no redundancy. Class 2: redundancy. Class 3: same as 2, plus physical separation (A60 fire boundaries).
• “What is an FMEA, and how does it relate to your daily DP operations?” — Failure Mode and Effects Analysis. You must know your vessel’s critical single-point failures. If you can’t answer this, the interview is over.
• “Describe the DP position reference systems you’ve worked with.” — DGPS, DGNSS, HiPAP, Ranger, taut wire, Fanbeam, CyScan, Spottrack. Practical experience matters.
• “You lose one gyro on a DP2 vessel. What happens?” — How many gyros? Degraded mode? Consequence analysis?
• “What is a DP Annual Trial?” — IMCA M 190 standard. Systematic test of all DP-related systems.
• “Explain your vessel’s power management system and how it interacts with DP.” — Generator configuration, bus-tie arrangement, auto-start/stop logic, blackout recovery.
• “Drive-off vs. drift-off — what’s the difference?” — Drive-off: DP drives vessel off position (system error). Drift-off: vessel drifts due to loss of position-keeping ability.
• “What is your footprint plot and how do you use it?” — Maximum excursion envelope. Used to calculate safe working distances.

Scenario-based DP questions:

• “You’re 15m from a platform. Weather deteriorating. What’s your decision-making process?” — Capability plot, DP status, client consent, Master’s authority. The correct answer ends with: “If in doubt, we move off.”
• “During a crane operation, you get a yellow DP alert. What do you communicate and to whom?” — Bridge team, crane operator, on-deck personnel, offshore installation, client representative.

DP ASOG — The Question They WILL Ask in 2026

ASOG (Activity Specific Operating Guidelines) has become the industry standard for DP risk management, replacing the older traffic-light TAM approach. If you’re interviewing for any DP role in 2026, expect questions on ASOG.

• “What is ASOG and how does it differ from TAM?” — ASOG provides a pre-planned, vessel-specific decision framework. Unlike TAM’s simple green/yellow/red, ASOG defines specific equipment states, their consequences, and pre-agreed actions for each degraded condition. Based on IMCA M 220.
• “Walk me through how ASOG works in practice.” — The ASOG lists all critical DP equipment. For each state (normal, degraded, failed), there’s a defined action: CONTINUE, ADVISORY, REDUCED, or TERMINATE. Responses are pre-planned and agreed with the client.
• “Give an example of an ASOG trigger.” — “Lose one position reference: ADVISORY. Lose a second: REDUCED — cease crane operations. Third lost: TERMINATE — immediate move to safe position.”
• “Who develops the ASOG?” — Vessel operator, reviewed by DP team, agreed with client for each specific operation. A pipelay ASOG differs from a construction ASOG.
• “What is the DPO’s authority under ASOG?” — Absolute authority to terminate. No client pressure overrides this. If your answer doesn’t include this, you’ve failed the question.

Engineers on DP Vessels

• “Describe the thruster configuration on your last vessel. How were they grouped for redundancy?”
• “What maintenance do you perform on azimuth thrusters?”
• “Explain the UPS system and why it matters for DP operations.”
• “How does the power management system handle a generator trip during DP operations?”

🏗️ Offshore Construction & Support Vessels

Offshore interviews cover a wide spectrum — from PSVs to heavy-lift construction vessels. The common thread is operational complexity and multi-stakeholder environments.

AHTS-specific questions

• “Describe an anchor-handling operation you were involved in. What was your role?” — Rig move procedure: pre-lay survey, anchor pattern, pennant wire, chaser system, winch operation, communication with rig.
• “What is the bollard pull of your last vessel? How does it affect operations?” — Bollard pull determines what rigs and anchor systems you can handle. Know the number and practical implications.
• “Explain snap-back zone dangers during towing operations.” — Wire/rope recoil zones, deck marking, crew positioning. Life-or-death implications.
• “How do you calculate a towing plan?” — Bollard pull vs. resistive tow force, environmental loads, catenary, towline length.

PSV-specific questions

• “How do you manage deck cargo stability on a PSV?” — Cargo securing manual, GM calculations, deck load capacity, tank management.
• “Describe a cargo transfer to an offshore installation in heavy weather.” — Sea state limitations, crane coordination, deck crew safety, vessel positioning.

Construction vessel questions

• “Describe a pipe-lay operation and the vessel’s role.”
• “How do you coordinate between bridge and construction teams during J-lay?”
• “What is a lay-down area, and how do you manage position during heavy crane lifts?”

---

🔬 Survey & Hydrographic Vessels

Survey vessel interviews are niche but highly technical. These roles combine traditional seamanship with specialised geophysical or hydrographic operations.

• “What survey operations have you been involved in?” — Be specific: multibeam bathymetry, side-scan sonar, sub-bottom profiler, seabed CPT, environmental surveys.
• “How do you maintain vessel track accuracy during a survey line?” — DP operations, autopilot settings, line-keeping tolerance, speed management, turn procedures.
• “What is the relationship between vessel motion and data quality?” — Heave compensation, pitch/roll effects on beam geometry, MRU calibration.
• “How do you handle a survey party request that conflicts with safe vessel operation?” — Safety wins, but communicate alternatives.

---

🤖 ROV (Remotely Operated Vehicles)

ROV interviews are uniquely technical — part engineering, part piloting, part problem-solving. The industry is small, and interviewers often know your previous supervisors personally.

ROV Pilots / Pilot-Technicians

• “What ROV systems have you worked with?” — Name specific models: Schilling HD, Kystdesign Merlin, Oceaneering Millennium Plus, Saab Seaeye. Quantify your hours.
• “Describe a typical subsea intervention you’ve piloted.” — Valve operations, hot stab connections, CP survey, pipeline inspection. Depth, visibility, tooling.
• “How do you handle an umbilical entanglement at depth?” — Assessment first — do NOT pull. Identify point via camera, assess current, communicate with supervisor.
• “What is TMS and why is it critical?” — Deployment/recovery, umbilical protection, garage mode, depth compensation.
• “Describe your pre-dive checks.” — Hydraulics, cameras, lights, sonar, manipulators, tooling, umbilical, TMS, comms. Systematic approach.
• “ROV loses one thruster at 200m near a structure. What do you do?” — Assess controllability, move away from structure, inform supervisor, decide on degraded ops or recovery.

Maintenance / technician side

• “What hydraulic system maintenance have you performed?”
• “How do you troubleshoot a manipulator losing grip strength?”
• “Experience with fibre-optic vs. steel-armoured umbilicals?”

---

🛡️ HSE (Health, Safety & Environment)

HSE questions appear in every maritime interview, but dedicated HSEQ roles face a much deeper dive:

Universal HSE questions (asked across all roles)

• “What is your Stop Work Authority experience?” — Give a specific example where you (or a colleague) stopped a job. What triggered it, what happened after.
• “Describe a near-miss you reported and what changed as a result.” — Reporting culture is key. Event → investigation → corrective action → verification.
• “How do you conduct a Toolbox Talk?” — Topic selection, crew engagement, documentation, feedback loop.
• “Walk me through a Job Safety Analysis / Risk Assessment for [specific task].” — Hazard identification → risk matrix → controls → communication → PPE.

Dedicated HSEQ role questions

• “How do you implement ISM Code requirements onboard?” — Safety Management System, document control, internal audits, management review, continuous improvement.
• “Describe your experience with SIRE / CDI / OVID inspections.” — Preparation, common findings, corrective action tracking, crew coaching.
• “How do you handle a reluctant crew member who consistently ignores PPE requirements?” — Education first, then documentation. Escalation ladder.
• “What KPIs do you track for safety performance?” — LTIR, TRIR, near-miss ratio, observation cards, drill completion rates.

---

🛢️ Oil & Gas Platform Support

Working in the upstream oil & gas sector means understanding the interplay between marine operations and production facilities:

• “Describe your experience working within a 500m safety zone.” — Communication protocols, DP operation near installations, standby procedures, EER support.
• “How do you coordinate helicopter operations on deck?” — HLO duties, deck preparation, refuelling procedures, fire crew readiness.
• “What is your experience with FRC / daughter craft operations for crew transfer?” — Launch/recovery, coxswain duties, sea state limitations, transfer procedures.
• “Explain the process for hot work planning near hydrocarbon areas.” — Gas testing, fire watches, permit conditions, ventilation.
• “What OPEP (Oil Pollution Emergency Plan) actions are you familiar with?” — Tier levels, containment, reporting, dispersant use, SOPEP equipment.

---

🌬️ Wind Energy (Offshore Wind)

The fastest-growing maritime sector has its own interview culture — younger companies, project-based contracts, and a strong emphasis on technician transfer safety:

CTV (Crew Transfer Vessel) roles

• “Describe a turbine approach in challenging conditions.” — Fendering, push-on force, sea state assessment, technician transfer decision.
• “What are the IMCA guidelines for crew transfer?” — IMCA M 202, transfer limits, master’s authority to refuse.
• “How do you manage multiple turbine stops in one shift?” — Route planning, fuel management, weather windows, fatigue.

🏢 Manning Agencies: What They’re Really Doing

Most maritime jobs go through manning agencies. Understanding how they work changes how you prepare.

How Agency Interviews Differ from Direct Hire

Manning agency recruiters are filtering, not selecting. They screen you on behalf of the end client. Their goal:

1. Verify your documents are current and genuine. Expect them to check every certificate date.
2. Confirm you match the position requirements. Rank, experience type, vessel type, flag state.
3. Assess if you’ll embarrass them. They put their reputation on the line by recommending you.

Agency recruiters often have a checklist — literally:

Agency-Specific Tips

• Respond fast. Agencies work on speed. If they call and you don’t answer, they call the next candidate. Return calls within hours, not days.
• Send documents in PDF, not photos. A blurry phone photo of your CoC screams unprofessional.
• Don’t argue salary with the agent. They have a budget from the client. If it’s too low, decline politely — don’t negotiate aggressively with the middleman.
• Update your profile on CrewBase and other platforms. Agencies search databases by certificate type, vessel experience, and availability. If your profile is outdated, you’re invisible.
• Be honest about your experience. Agencies cross-check with previous employers. Getting caught in a lie blacklists you — not just with that agency, but within their network.

✅ Pre-Interview Checklist

Print this. Go through it the night before every interview.

Documents

• CV updated with latest vessel and rank
• All certificates — know expiry dates by heart
• Discharge book / CDC — latest entries visible
• Medical certificate — valid and relevant to the sector
• Passport — 6+ months validity
• Digital copies accessible on your phone/cloud

Technical Prep

• Review your last 3 vessels: name, IMO number, flag, DWT/BHP, DP class, cargo system
• Refresh yourself on the specific vessel type you’re interviewing for
• Prepare 2–3 STAR-format examples (emergency, teamwork, problem-solving)
• Research the company: fleet size, vessel types, key operations, recent news

Practical

• Test your internet connection (online interviews)
• Camera, microphone, lighting checked
• Quiet room, no interruptions
• Prepare 3–5 questions for the interviewer
• Know your salary expectation (research market rate first)
• Know your availability date — specific, not “soon”

The Bottom Line

Maritime interviews reward specificity over generality. The candidate who says “I worked on a 2015-built Suezmax, 158,000 DWT, with Kongsberg DP2, Framo deepwell pumps, and an IGS capacity of 12,500 m³/h” will always beat the one who says “I worked on a large tanker.”

Know your vessels. Know your systems. Know your procedures. And know when to say “I would stop the operation” — because in maritime, the willingness to abort is the ultimate proof of competence.

The interview is not a test you pass or fail. It’s a conversation where you demonstrate that you’re safe, competent, and worth crewing with for months at sea.

Prepare thoroughly. Answer specifically. Ask smart questions. And update your CrewBase profile with your latest experience and certifications — because the best interview is one where they already know you’re qualified before the call starts.
