Marine Risk Assessment Online Generator

Q: How is the marine 5×5 Risk Matrix scored?

The Risk Score is calculated as Likelihood (1–5) multiplied by Severity (1–5) across four bands: Low (1–4), Medium (5–9), High (10–14), and Critical (15–25, which mandates Stop Work Authority).

Q: What does the ALARP principle mandate on board ships?

ALARP (As Low As Reasonably Practicable) requires operators to implement risk barriers across the hierarchy of controls until residual risk is verified in the acceptable range.

Q: How does MARA support OCIMF SIRE 2.0 Chapter 5 compliance?

MARA integrates human factor Performance Influencing Factors (PIF), Toolbox Talk verification, and Stop Work Authority controls aligned with the CVIQ vetting protocol.

Q: Can MARA be used at sea without internet connectivity?

Yes, MARA runs 100% client-side inside the browser using LocalStorage caching and standalone file export/import features.

Q: How does the official PDF/Print function handle shipowner branding?

The platform allows loading a PNG/JPG company logo directly into browser memory, auto-rendering it on the clean A4 landscape inspection report.

ALARP Risk Acceptance Criteria:

1–4 (LOW): Broadly acceptable risk. Operations continue under standard Safety Management System (SMS) routines.

5–9 (MEDIUM): Tolerable under controlled conditions. Standard mitigations and Toolbox Talk required.

10–14 (HIGH): Requires enhanced supervision by Task Leader, PTW permit, and ongoing monitoring.

15–25 (CRITICAL): UNACCEPTABLE RISK. Stop Work Authority (SWA) must be invoked immediately! Work prohibited.

Hierarchy of Risk Controls:

Elimination: Physically remove the hazard.
Substitution: Replace the hazard with a safer alternative.
Engineering Controls: Ventilation, mechanical barriers, LOTO.
Administrative Controls: Training, procedures, checklists, PTW.
PPE: Personal protective equipment as final safety barrier.

Shipboard Risk Assessment & Toolbox Meeting: IMO ISM Code, OCIMF SIRE 2.0 & TMSA 3

Formalized risk assessment is a mandatory pillar of shipboard safety management dictated by Section 1.2.2 of the IMO ISM Code and the UK MCA Code of Safe Working Practices for Merchant Seafarers (COSWP). Under the updated inspection regime of OCIMF SIRE 2.0 (Chapter 5) and TMSA 3 (Element 9), oil majors and Port State Control (PSC) authorities strictly penalize generic, duplicated paperwork. Every risk assessment must reflect real-time operational hazards, rigorous barrier safeguards across the hierarchy of controls, and a genuine evaluation of Performance Influencing Factors (PIF).

The NavLib Marine Risk Assessment Pro (MARA) replaces rigid spreadsheets with a purpose-built digital bridge and engine room console. The platform features an industry-standard 5×5 Risk Matrix engine (Likelihood × Severity), real-time ALARP verification, a preloaded database of 40 standard maritime operations, comprehensive Toolbox Talk (TBT) briefing logs, and an isolated A4 landscape printing architecture with company logo branding.

Frequently Asked Questions: Marine Risk Assessment & Vetting Audits (FAQ)

How is the marine 5×5 Risk Matrix scored?

The Risk Score is calculated as Likelihood (1–5) × Severity (1–5) on a 1 to 25 scale, categorized into four actionable tiers:

1–4 (LOW): Broadly acceptable under standard Safety Management System (SMS) routines.
5–9 (MEDIUM): Tolerable with specific controls and a documented pre-job Toolbox Talk (TBT).
10–14 (HIGH): Substantial risk requiring a formal Permit to Work (PTW) and direct officer supervision.
15–25 (CRITICAL): Intolerable risk. Immediate trigger for Stop Work Authority (SWA) — operation is strictly prohibited.

What does the ALARP principle mandate on board ships?

ALARP (As Low As Reasonably Practicable) requires operators to reduce initial operational risks until further risk reduction is disproportionate to the required resource investment. In practical terms, this requires implementing the hierarchy of controls (Elimination, Substitution, Engineering barriers, Administrative rules, PPE) so that the residual risk score rests safely in the Low or Tolerable bands.

How does MARA support OCIMF SIRE 2.0 Chapter 5 compliance?

SIRE 2.0 vetting inspectors evaluate crew engagement rather than passive paperwork. MARA incorporates dedicated fields for Toolbox Talk timing, responsible personnel sign-offs, and critical Performance Influencing Factors (PIF) such as time pressure, adverse weather, and equipment limitations, ensuring full alignment with the inspector's CVIQ questionnaire.

Can MARA be used at sea without internet connectivity?

Yes. The suite is 100% client-side and requires no external database or server back-end. Active drafts are automatically cached in the browser's LocalStorage, and complete safety registries can be exported or imported as structured files for shipboard archive storage and auditing.

How does the official PDF/Print function handle shipowner branding?

Users can click the logo slot in the header to upload their company insignia (PNG or JPG). The image is preserved in local memory and rendered into the header of the official A4 landscape print layout, isolated from all external web advertisements or navigation menus.
