Shipping is short of officers, and the gap is widening. Every fleet operator, terminal and training centre now faces the same question: how do you bring people to competence faster, without more sea time you don't have, and more classroom days nobody can spare?
Simulators are the obvious answer. Choosing the right kind of simulator is where most budgets go wrong.
A maritime training simulator is a real-time digital environment that replicates vessel systems, bridge operations, engine room machinery or cargo handling so crew can build and demonstrate competence without a live ship.
They range from full-mission Class A installations used for STCW certification through to custom desktop and browser-based simulators used for familiarisation, procedure training and vessel-specific operations. Most operators need both, and buy them from different suppliers. Key Takeaways
The Pressure: Shipping faces a shortfall of 39,100 STCW-certified officers in 2026, and needs 113,735 additional officers by 2030.
The Scale: 2.57 million seafarers currently operate 85,148 merchant ships worldwide.
The Trend: Demand for STCW-certified seafarers has risen 35% since 2021.
What STCW Mandates: Simulator training is mandatory under STCW strictly for radar/ARPA and ECDIS. Ship handling, cargo handling, GMDSS and machinery simulation are permitted but optional.
The Training Effect: Enterprise studies show immersive learners train up to 4× faster and feel 275% more confident applying what they learned compared to classroom settings.
The Buying Mistake: Trying to solve vessel-specific, procedure-level training with a generic full-mission simulator — the wrong tool at the highest price.

1. Why Maritime Simulator Demand Is Rising Now
Short answer: the officer supply gap has become structural, and simulation is the only training lever that scales without more ships, more berths or more instructors.
The BIMCO and International Chamber of Shipping Seafarer Workforce Report 2026 estimates a shortage of 39,100 STCW-certified officers this year, alongside a surplus of 56,890 ratings — a shortage of the right people, not people in general. Meeting projected demand requires an additional 113,735 officers by 2030, or roughly 22,747 new officers joining each year.
Three things follow from that, and each one is a purchasing trigger:
Promotion timelines are compressing: Officers are stepping up faster than the traditional sea-time-plus-experience model assumed. The experience gap has to be closed somewhere, and simulation is the only environment where a junior officer can encounter twenty cargo emergencies in a week.
Fleets are more heterogeneous: Dual-fuel, LNG, methanol, battery-hybrid and increasingly automated systems mean crew rotate onto vessels with systems they have never physically operated. Generic training does not cover vessel-specific systems.
The surplus of ratings is an opportunity, not a footnote: A surplus at rating level and a shortage at officer level is, in effect, a training problem. Operators who can accelerate progression from rating to officer solve their own crewing problem.
2. What STCW Actually Requires and What It Doesn't
This is where a great deal of budget is misallocated, because the regulatory position is widely misunderstood.
Under the STCW Convention as amended, simulator training is mandatory only for radar/ARPA and — since the 2010 Manila amendments — ECDIS. Simulator use for ship handling, cargo handling, GMDSS communication, and propulsion and auxiliary machinery operation is permitted and widely used, but optional.
Two further points matter commercially:There are two different performance standards. STCW distinguishes between simulators used for training and simulators used for assessment of competence, with the latter held to a stricter standard. A simulator that is entirely appropriate for building skills may not be acceptable for certifying them. Decide which you are buying before you scope it.Approval is granted by the administration, not the vendor. Whether a simulator is acceptable for a given purpose is determined by the flag state or maritime administration, and instructors and assessors are themselves expected to be trained — IMO Model Course 6.10, Train the Simulator Trainer and Assessor, is the usual reference. No developer can grant you compliance. Any vendor implying otherwise should be treated with caution.
The practical implication: A very large share of valuable maritime training — familiarisation, vessel-specific procedures, cargo operations rehearsal, emergency response, onboarding — sits entirely outside the mandatory certification perimeter. It does not require a Class A installation. It requires an accurate, well-designed simulator that reflects your vessels. That is a completely different purchase.
3. The Six Types of Maritime Training Simulator
Simulator Type | What It Covers | Typical Setting | Relative Investment | Used for Certification? |
Full-Mission Bridge (Class A) | 360° visual, full bridge console, motion cues | Training academy | Highest | Yes, where approved |
Engine Room / Machinery Simulator | Propulsion, auxiliaries, fault diagnosis, ERM | Academy or fleet centre | High | Yes, where approved |
Cargo & Ballast Handling Simulator | Tanker, LNG/LPG, bulk cargo, ballast operations | Academy or operator | Medium–High | Yes, where approved |
Desktop / Part-Task Simulator | Specific systems or procedures, single workstation | Office, training room, onboard | Medium | Sometimes, for specific tasks |
Custom Vessel-Specific Simulator | Your vessel, your systems, your procedures | Browser, desktop, onboard | Medium | Generally supplementary |
VR Immersive Training | Enclosed space entry, emergency response, spatial familiarisation | Training centre or onboard | Medium–High | Supplementary |
How to read this table: The top three are equipment purchases from established simulator manufacturers. The bottom three are software development projects. They solve different problems and confusing them is the most expensive mistake in this category.
4. The Gap Most Fleets Have: Full-Mission vs. Vessel-Specific
Here is the pattern we see repeatedly: an operator has access to full-mission simulator training through an academy — bought, budgeted, working. And separately, they have PDFs.
Between those two sits everything that actually causes incidents: how this cargo system on this class of vessel behaves, what the correct sequence is for this operation, what the alarm response is for this configuration.
Full-mission simulators are generic by design — they teach transferable competence, which is exactly what certification requires. They are not built to replicate your specific vessel, your specific cargo system, or your company's specific procedures. And rebuilding a Class A installation for every vessel class in your fleet is neither affordable nor sensible.
That gap is what custom, vessel-specific simulation fills. It is delivered as software rather than a physical installation, distributed to crew wherever they are, and updated when procedures change.
A useful test: If the training need is "our officers must be certified competent to a national standard," buy full-mission capability or academy access. If the need is "our crew must operate our systems correctly and consistently across the fleet," build vessel-specific. Most operators need both. Very few need two of the first.
5. What Drives the Cost of a Custom Maritime Simulator
There is no list price, because you are commissioning software, not buying a product. What follows is what a real quote gets built from:
Cost Driver | Lower Cost Scope | Higher Cost Scope | Key Scoping Notes |
Vessel & System Scope | One system on one vessel class | Multiple systems across several classes | The single largest scoping decision |
Model Fidelity | Representative behaviour | Validated physical or process modelling | Real fluid, thermal or hydraulic modelling requires marine engineering input |
3D Environment Detail | Key compartments and equipment | Full walkable vessel | Drives modelling effort heavily |
Scenario Count | Normal operations only | Full fault, emergency and edge-case library | Scales close to linearly — the main creep risk |
Assessment & Scoring | Practice only | Scored competency with audit trail | Required for any evidence-bearing use |
Delivery Targets | Browser only | Browser + onboard offline + VR | Each adds QA and testing effort |
Integration | Standalone | LMS, crewing system, SSO, planned maintenance | Consistently underestimated by buyers |
Languages | English only | Multiple crew nationalities | Affects audio, UI and procedural variants |
Maintenance | One-off build | Continuous updates as fleet and procedures change | Budget from day one |
The insight that decides value: Buyers focus on the 3D visuals. Cost and training value actually concentrate in the scenario logic and assessment design. A photoreal engine room with one linear walkthrough teaches less than a modest model with twenty well-constructed failure scenarios.
Before requesting quotes, answer four questions: which vessel classes, which systems, how many scenarios, and does it need to produce evidence. Those four answers move a quote more than anything else you can specify.
6. Building the ROI Case
Maritime simulator business cases are strongest when built on operational risk and crewing economics, not on training engagement metrics:
Incident and damage avoidance: Cargo operations, mooring, enclosed-space entry and machinery handling failures produce claims, off-hire, damage and pollution exposure. Use your own claims data and near-miss reports. Even a small reduction against a real claims history is a large, credible number — and it is the number underwriters and senior management actually respond to.
Reduced off-hire and operational delay: Delayed or aborted cargo operations, port delays caused by procedural error, and equipment damage from incorrect operation all carry direct daily costs you can price precisely.
Compressed time-to-competence: Calculate using this simple formula:
$$\text{Savings} = (\text{Days of ramp reduction per officer}) \times (\text{Fully loaded daily cost}) \times (\text{Officers per year})$$
In an officer shortage, faster progression has strategic value beyond the arithmetic — it is the difference between crewing a vessel and not. PwC's enterprise study found immersive learners completed training up to four times faster than classroom learners.
Travel, instructor and berth cost avoided: Bringing crew to a training centre means flights, hotels, instructor days and time out of rotation. Distributing training to the vessel or to crew at home removes most of that, and scales at near-zero marginal cost per additional seafarer.
Retention: Seafarer retention is now a board-level issue, and access to good training is a documented factor in career decisions. Harder to quantify, but worth stating explicitly in the case — because the cost of replacing a trained officer in a shortage market is not small.
The scale argument to make explicitly: PwC found immersive training reached cost parity with classroom delivery at 375 learners and was 52% cheaper at 3,000 learners. A simulator scoped for one vessel class costs nearly the same to build as one scoped for a fleet-wide population of officers, ratings and new joiners. Scope for the widest plausible audience from the start.
7. Build vs. Buy
Training Option | Right When... | Trade-Off |
Academy / Third-Party Simulator Access | Certification-bearing STCW training | Generic by design; limited availability; travel required |
Off-the-Shelf Maritime E-Learning | Generic safety, regulatory awareness, induction | Cannot represent your vessels or procedures |
Commercial Simulator Product Licence | Standard vessel types, established training centre | Configuration limits; recurring licence cost |
Custom-Built Simulator | Vessel-specific systems, company procedures, fleet-wide distribution | Higher upfront; needs a partner with marine domain understanding |
Hybrid Model | Almost all fleet operators | Multiple suppliers to coordinate |
The honest framing: Buy your certification-bearing training. Build your vessel-specific training. Trying to force either one to do the other's job is how simulator budgets get wasted.
8. Implementation Roadmap
Define the competency, not the technology: Write down exactly what a crew member must be able to do and how you will know they can. If you cannot write the assessment criteria, the project is not ready. This phase prevents more failure than any other.
Audit what documentation exists: General arrangement drawings, system schematics, P&IDs, company procedures, incident and near-miss reports, existing training material. Available documentation is the biggest accelerator; missing documentation is the biggest hidden cost.
Design scenarios from your own incident history: This is the highest-value step and the most commonly skipped. Your near-miss reports are a scenario library that no generic simulator can match.
Prototype one module: One system, one vessel class. Put it in front of serving officers and superintendents. Everything learned here is cheaper than learning it in module ten.
Pilot with measurement: Choose two or three metrics before you start — assessment scores, time-to-competence, procedural error rate — not after.
Distribute and integrate: LMS connection, crewing system links, onboard deployment, instructor enablement. Involve masters, chief engineers and superintendents early; they determine whether it is actually used.
Maintain it: Fleets change, procedures change, regulations change. Assign an owner and a review cycle. A simulator teaching a superseded procedure is worse than no simulator at all.
Timeline reality: A focused single-system module is typically weeks to a few months. A fleet-wide programme with assessment and integration is a multi-quarter engagement. Any vendor promising a fleet programme in weeks has not understood the scope.
9. Technology, Delivery and the Bandwidth Problem
Real-time 3D engine: Unity and Unreal Engine dominate. Unity generally offers broader deployment reach across browser, desktop and mobile; Unreal leads on visual fidelity. The engine matters far less than the developer's marine domain understanding.
The constraint unique to shipping — Connectivity: This is where generic e-learning vendors fail maritime clients. Satellite bandwidth is limited, expensive and variable. If training is expected to run onboard, it must work offline, sync when connectivity allows, and never depend on streaming. Ask about this explicitly and early — retrofitting offline capability is painful and sometimes impossible.
Delivery split that works in practice: Browser-based for shore staff, cadets and crew at home; downloadable offline package for onboard use; VR reserved for spatial and emergency scenarios at training centres.
Standards and integration: SCORM is broadly supported. xAPI (Tin Can) is the better fit for simulators because it captures granular data — which steps failed, how many attempts, how long each took — rather than just completion. For crew competence tracking, that granularity is the entire point. Integration with crewing and competence-management systems is what turns training data into deployment decisions.
Data sensitivity: Vessel drawings, system schematics and company procedures are commercially sensitive. Establish where models are stored, who can access them, what the developer may reuse, and what happens to your assets at contract end. Put it in the contract, not the kick-off deck.
10. Approvals, Compliance and Evidence
Three things to get right before you build:
Know which side of the certification line you are on. If the simulator is intended to support certification or formal assessment of competence, engage your flag state administration or recognised organisation before development, not after. Requirements vary by administration and the stricter assessment performance standard applies.
Design the evidence trail from the start. Any training that must be demonstrable to a flag state, port state control, vetting inspection or customer audit needs timestamped, per-seafarer, per-attempt records with documented assessment criteria. Retrofitting an audit trail into a finished simulator is expensive.
Do not accept compliance claims from a developer. A software developer can build a simulator that meets a defined performance specification. Only an administration can approve it for a regulated purpose. Treat any vendor who blurs that line as a risk.
11. Seven Mistakes That Waste Maritime Simulator Budgets
Buying full-mission capability to solve a vessel-specific problem. The most expensive error in this category, by a wide margin.
Assuming a developer's simulator confers STCW compliance. Verify with your administration first.
Ignoring onboard connectivity. A beautiful simulator that cannot run at sea will not be used at sea.
Scoping only normal operations. The value is in the failures. Build the emergency and fault scenarios.
Not using your own incident data. Your near-miss reports are the best scenario source you will ever have, and they cost nothing.
Excluding masters, chief engineers and superintendents. They decide whether it becomes standard practice or shelfware.
No maintenance budget. Fleet and procedural change will make an unmaintained simulator inaccurate within about two years.
12. Twelve Questions to Ask Any Maritime Simulator Developer
Which maritime systems or vessel types have you actually simulated — and can we speak to that client?
Who on your team understands marine operations, as opposed to 3D development?
Will this run fully offline onboard, and how does it sync?
How do you validate technical accuracy, and who signs off?
What LMS and competence-management standards do you support — SCORM, xAPI, both?
How is per-seafarer performance data captured, stored and exported for audit?
What happens to our vessel models, drawings and source files at contract end?
What is the annual maintenance and update model, and what does it cost?
Can the architecture extend from browser to VR later without a rebuild?
Will you build one prototype module before we commit to a fleet programme?
How do you work when our technical documentation is incomplete?
What has gone wrong on a previous simulator project, and what changed as a result?
Question 12 is the most revealing one on the list. A developer who has delivered real maritime simulators has a specific, uncomfortable, honest answer. A vendor who claims nothing has ever gone wrong is telling you how little they have shipped.
13. How EC Infosolutions Builds Maritime Training Simulators
EC Infosolutions has engineered software for industrial and enterprise clients since 2007 — 19+ years, with maritime and logistics as core industry practices. Our simulation and digital learning team builds custom, vessel-specific training simulators: real-time 3D environments that replicate your systems, your procedures and your operational scenarios.
Delivered work includes our interactive VLCC Engine Room Interactive Maintenance & Inspection Simulator developed for tanker operations training, alongside simulation projects in heavy machinery and rail operations. Through our NAVI-SIM platform, we build custom desktop, web, and VR simulations for marine training centres and fleet operators worldwide.
Where we fit, stated plainly: We do not manufacture Class A full-mission installations, and we do not issue compliance approvals. We build the vessel-specific, procedure-level, fleet-distributable simulation layer that sits between academy certification training and your PDF manuals — the layer most operators are missing.
Where a programme needs to scale across many vessels, ranks and languages, our Learning Stack platform provides the delivery, tracking and assessment layer. Where the simulator needs to connect to operational or fleet data, our AI and data engineering team handles the integration.
What to Do Next
If you are evaluating simulation for your fleet or training centre, the useful next step is a 30-minute scoping conversation: which vessel classes, which systems, which competencies, how many seafarers, what documentation exists. That is enough for us to tell you what shape a build would take, what it would take to prove the case internally — and whether a custom simulator is the right answer at all.
If your requirement is genuinely certification-bearing full-mission training, we will tell you that and point you toward the right kind of supplier. Faster for everyone.

Frequently Asked Questions (FAQs)
Q1. What is a maritime training simulator?
A maritime training simulator is a real-time digital environment that replicates vessel systems, bridge operations, engine room machinery or cargo handling so crew can build competence without a live ship. Types range from full-mission Class A bridge installations used in certification training through to desktop, browser and VR-based simulators used for familiarisation, vessel-specific procedures and emergency rehearsal. Most operators end up using more than one type, sourced from different suppliers.
Q2. Is simulator training mandatory under STCW?
Only partly. Under the STCW Convention as amended, simulator training is mandatory for radar and ARPA, and — following the 2010 Manila amendments — for ECDIS. Simulator use for ship handling, cargo and ballast handling, GMDSS and machinery operations is permitted and widely practised but not mandatory. STCW also applies a stricter performance standard to simulators used for assessing competence than to those used for training, so the intended purpose must be established before procurement.
Q3. Can a custom-built simulator be used for STCW certification?
Possibly, but that decision belongs to your flag state administration or recognised organisation, not to the software developer. If certification or formal competence assessment is the goal, engage the administration before development begins, since the assessment performance standard is stricter and instructors typically need simulator-specific training such as IMO Model Course 6.10. Many custom simulators are deliberately built for supplementary training outside the certification perimeter, which avoids this entirely.
Q4. How much does a custom maritime simulator cost?
There is no list price, because it is software development rather than a product purchase. Cost is driven by how many vessel classes and systems are covered, model fidelity, the number of scenarios, whether scored assessment and audit trails are required, how many delivery formats are needed, integration depth, and language coverage. A single-system browser module and a fleet-wide programme with assessment differ by an order of magnitude. Any quote given before scoping is a guess.
Q5. How long does it take to build?
A focused single-system module typically takes weeks to a few months, depending heavily on the quality of available technical documentation. A fleet-wide programme with assessment, multi-language support and integration is a multi-quarter engagement. The strongest predictor of timeline is not development speed but how complete and accurate your existing drawings, schematics and procedures are.
Q6. Will it work onboard with limited satellite bandwidth?
It must, if crew are expected to use it at sea — and this should be a hard requirement rather than a preference. A properly built maritime simulator runs fully offline onboard and syncs results when connectivity is available, without depending on streaming. This is a common failure point for e-learning vendors without maritime experience, and retrofitting offline capability is difficult and sometimes not possible at all.
Q7. What is the difference between full-mission and custom simulators?
Full-mission simulators are physical installations with consoles and wraparound visuals, built for transferable, certification-bearing competence, and generic by design. Custom simulators are software built to replicate specific vessels, systems and company procedures, distributed to crew wherever they are. They solve different problems: full-mission proves general competence to a standard, custom builds correct operation of your actual equipment. Confusing the two is the most expensive mistake in this category.
Q8. Can it integrate with our LMS or crewing system?
Yes. SCORM is widely supported, and xAPI is generally the better choice for simulators because it captures granular interaction data — which steps failed, how many attempts, how long each took — rather than just completion status. Integration with crewing and competence-management systems is what converts training data into deployment decisions, and should be specified at requirements stage rather than added later.
