SIRE 2.0 Explained: What It Is and What It Means for Vessel Owners

If you operate, manage, or own a tanker, you have likely heard the term SIRE 2.0 mentioned with increasing urgency over the past year or two. Since going live on 2 September 2024, it has become the mandatory inspection standard for all OCIMF vetting inspections, and its impact on the tanker industry has been significant.

This article breaks down what SIRE 2.0 actually is, how it differs from the previous system, what the inspection process looks like in practice, and — most importantly — what it means for your vessel’s commercial performance and tradability.

What is SIRE 2.0?

SIRE stands for Ship Inspection Report Programme. It was first introduced in 1993 by the Oil Companies International Marine Forum (OCIMF) as a standardised framework for assessing the safety, condition, and operational practices of tankers and barges. The original programme gave oil majors, charterers, and terminal operators a common basis for evaluating whether a vessel was suitable for their operations.

SIRE 2.0 is the next generation of that programme, a comprehensive overhaul that replaces the previous version (known as VIQ7) with a digitised, risk-based inspection regime.

Simply put: SIRE 2.0 is the new standard by which tankers are inspected and assessed. If your vessel trades in the international tanker market, a SIRE 2.0 inspection will determine whether oil majors and charterers accept or reject you for employment.

Why was SIRE 2.0 introduced?

The original SIRE programme served the industry well for three decades, but it had limitations. The fixed-checklist format made inspections relatively predictable, and it placed most of its focus on the physical hardware of the vessel: equipment, machinery and certificates.

Over time, the maritime industry recognised that safety incidents rarely result from hardware failure alone. Human factors (such as crew competence, decision-making, safety culture and onboard procedures) play an equally critical role. The original programme did not adequately account for these.

SIRE 2.0 was designed to address this gap while also taking advantage of modern digital technology. The goal, as OCIMF has stated, is to more accurately report on the quality of a vessel and its crew on an ongoing basis, and to provide a better indicator of future performance.

How is SIRE 2.0 different from the previous system?

The differences are substantial enough that many in the industry have described SIRE 2.0 as a paradigm shift rather than an upgrade. Here are the most important changes:

1. Fully digitised inspections

Inspections under SIRE 2.0 are conducted entirely in digital format. The inspector uses an intrinsically safe tablet device to complete the inspection questionnaire in real time. This also allows for photographs to be taken and attached directly to specific findings during the inspection, improving the accuracy and traceability of the final report.

2. A risk-based, algorithmically generated questionnaire

One of the most significant structural changes is the move away from a fixed checklist. Under the old VIQ7 system, the questionnaire was largely predictable — operators could review a standard set of questions and prepare accordingly.

Under SIRE 2.0, each inspection uses a Compiled Vessel Inspection Questionnaire (CVIQ) that is generated specifically for your vessel by an algorithm. The algorithm draws from a question library of over 550 questions and selects approximately 100 for each inspection, based on vessel type, equipment, operational history, and data provided by the operator. No two inspections are identical.

The CVIQ is made up of four categories of questions:

• Core Questions → Safety-critical questions that appear in every inspection, covering risks that could lead to a catastrophic or severe incident. These make up approximately 50% of every CVIQ.
• Rotational Questions → Non-core questions that rotate across inspections to ensure comprehensive coverage over time.
• Campaign Questions → Time-limited questions addressing emerging industry concerns or trends.
• Conditional Questions → Questions triggered by specific vessel characteristics or data declared by the operator in pre-inspection submissions.

This means the days of reviewing the same set of questions before each inspection are over. Broad, continuous readiness is now the only effective strategy.

3. The human factor

Perhaps the most consequential change in SIRE 2.0 is the formal integration of human factors into the inspection framework. OCIMF recognised that the majority of maritime incidents are not caused by broken equipment — they are caused by how people interact with that equipment. The new system reflects this directly.

Every question in the CVIQ is assessed across three dimensions:

• Hardware — The physical condition of equipment and systems
• Processes — The quality of the Safety Management System (SMS) and onboard procedures
• Human Factors — Crew competency, behaviour, and Performance Influencing Factors (PIFs)

What makes this genuinely different in practice is that inspectors now look beyond the logbook. Rather than simply confirming that a drill was recorded, an inspector will interview the crew to verify they actually understand the procedure — the “why,” not just the “what.” This is a material shift in how inspections are conducted.

Inspectors also formally assess Performance Influencing Factors (PIFs) — conditions that affect a person’s ability to perform safely. These include crew fatigue, workload, alarm overload on the bridge, and the quality of communication between team members. Critically, inspectors also assess psychological safety: whether crew members feel genuinely empowered to stop a task if they believe it poses a risk, without fear of consequence.

This broader scope means that equipment failures and crew knowledge gaps are no longer evaluated in isolation. Constantly recurring equipment breakdowns, for instance, create stress and fatigue that directly translate into negative human factor observations during a vetting inspection. The condition of your equipment and the wellbeing of your crew are now, formally, two sides of the same coin.

Critically, multiple observations can be recorded under a single question. For example, if a 15 PPM bilge monitor is found to be out of calibration (a hardware deficiency) and the crew member responsible cannot walk the inspector through the calibration process (a human factor), both will be recorded as separate negative observations under the same question. For zero-tolerance items — such as 15 PPM monitors, Oil Discharge Monitoring Equipment (ODME), and gas detectors — this combination of hardware deficiency and crew unfamiliarity represents one of the highest-risk outcomes in a SIRE 2.0 inspection.

The underlying philosophy of SIRE 2.0 is a deliberate move away from “the inspector is coming, prepare the vessel” toward a culture of continuous improvement, where safety standards are maintained not for the inspection, but as part of how the ship operates every day.

4. Greater operator responsibility before the inspection

Under SIRE 2.0, vessel operators carry significantly more responsibility for the quality and accuracy of data submitted before the inspection takes place. Operators must complete and keep current:

• The Pre-Inspection Questionnaire (PIQ) — Operational history, planned activities, and vessel-specific declarations
• The Harmonised Vessel Particulars Questionnaire (HVPQ) — Technical details about the vessel and its equipment
• A Photo Repository — Standardised photographs of the vessel, which must be updated within a six-month rolling window
• Certificates, Class Survey Status Reports and PSC records

The CVIQ is only generated and released to the inspector after the operator has completed the Pre-Inspection Declaration. This means the data you submit directly influences which questions the algorithm selects. Inaccurate or incomplete declarations can trigger conditional questions you may not be prepared for.

What does SIRE 2.0 mean for vessel owners and operators?

Higher observation counts are now normal

Under the previous system, five or six inspection findings were considered concerning, and ten to fifteen would have been regarded as a serious performance failure. Under SIRE 2.0, the volume of findings has increased significantly across the industry, with some inspections producing 20 or more observations.

This is not necessarily a reflection of lower vessel standards; it reflects a more thorough and granular inspection methodology. However, the industry is still calibrating expectations, and the commercial implications of high observation counts remain significant.

Negative observations directly affect tradability

A poor SIRE 2.0 result has tangible commercial consequences. Negative observations impact a vessel’s vetting profile and can lead to rejection by oil majors and charterers, directly affecting employment prospects and revenue. Because SIRE 2.0 places greater weight on historical performance data, a poor result today can have consequences that extend far into the future.

Preparation can no longer be reactive

The unpredictability of the CVIQ means that operators can no longer rely on pre-inspection cramming or focused preparation on a known set of questions. Effective SIRE 2.0 performance requires continuous operational readiness — systems, procedures, training and documentation that are inspection-ready as part of normal daily operations, not just in the weeks before a scheduled inspection.

Crew training and safety culture are now central

Because human factors are assessed formally in every inspection, crew knowledge, communication, and safety culture are now directly tied to commercial performance. This requires a genuine investment in training and in building a safety culture where crew members can articulate procedures confidently and demonstrate operational competence to an inspector.

Key steps to prepare for SIRE 2.0

If you are not already operating with SIRE 2.0 readiness in mind, here are the foundational areas to address:

1. Keep HVPQ and PIQ data current and accurate. Cargo type entries trigger specific questions; inaccurate data will generate questions you are not prepared for.
2. Maintain your Photo Repository within the six-month update requirement.
3. Train your crew across the full question library — not just the most commonly tested areas. Core questions cover catastrophic risk categories and will always appear.
4. Pay particular attention to zero-tolerance equipment. Items such as 15 PPM bilge monitors, ODME, and gas detectors are high-priority during any vetting inspection. Under SIRE 2.0, a deficiency with this equipment combined with a crew member who cannot demonstrate correct operating or calibration procedures will almost certainly result in a severe negative observation. Calibration compliance and crew familiarisation with this equipment are not optional — they are essential.
5. Invest in regular internal or third-party pre-inspection assessments to identify deficiencies before they appear on an official record.
6. Build inspection readiness into daily operations rather than treating it as a periodic event. Well-maintained equipment reduces crew stress and fatigue — factors that are now formally assessed under the PIF framework.

Mr. Marine: your partner for SIRE 2.0 readiness

Navigating SIRE 2.0 requires more than awareness; it requires the right support, from people who understand the inspection regime in detail and have direct experience working with vessel owners and operators in the tanker market.

At Mr. Marine, our services are directly aligned with the areas that SIRE 2.0 scrutinises most closely. Here is where we can make a practical difference for your fleet:

Crew training and equipment familiarization

Under SIRE 2.0, an inspector will not simply ask to see a calibration certificate. They will ask your crew to walk them through the calibration process, step by step, in real time. This means that technical compliance alone is no longer enough. Crew familiarization with the equipment they operate is now a formal compliance requirement for passing a vetting inspection.

Our Ballast Water Treatment System (BWTS) Training service is one clear example of where this matters. We do not just service the system; we ensure your crew understands it, can operate it correctly and can explain its function confidently to an inspector. This is the standard SIRE 2.0 demands, and it is the standard we train to.

We also provide calibration and familiarization support for Marine Instruments and Controls (MIC) equipment, including 15 PPM bilge monitors. Given that these are zero-tolerance items under SIRE 2.0, ensuring both accurate calibration and crew competence in their operation is one of the highest-value steps a tanker operator can take before a vetting inspection.

Preventing the equipment failures that create human factor observations

There is a direct and often underappreciated link between equipment reliability and crew wellbeing — and under SIRE 2.0, crew wellbeing is formally assessed. Recurring equipment breakdowns generate stress, fatigue, and operational burden on your crew. These are precisely the Performance Influencing Factors (PIFs) that an inspector is trained to identify and record.

Our BWTS Annual Health Check, Marine Elevator Annual Safety Inspections and MIC Calibration services exist to keep critical systems functioning reliably, reducing the likelihood of unexpected failures that place pressure on your crew and create the conditions for negative human factor observations during a vetting interview.

Putting it plainly: a well-maintained vessel is not just a technical asset. Under SIRE 2.0, it is also a crew wellbeing asset, and a commercial one.

The bottom line

SIRE 2.0 has changed the inspection landscape for tanker operators. The focus on human factors, crew competence and equipment familiarization means that the gap between technical compliance and actual inspection performance has never been more important to close.

Mr. Marine is here to help you close that gap; through targeted training, reliable equipment maintenance and the kind of practical, vessel-level support that translates directly into better vetting outcomes.
