B. Independent Marine Assurance Services

An independent layer of technical control

Greenport functions as an additional, independent layer between the project owner, operator, terminal, vessels, contractors and marine operations — identifying deviations early, verifying operational integrity, controlling risk and tracking findings systematically through to closure.

1. Operations Integrity 2. Marine HSEQ 3. Maritime Safety 4. Operational Risk 5. Regulatory Readiness 6. Performance Management
01 · Marine Operations Integrity Assurance

Independent oversight of critical marine systems

Independent oversight and follow-up of operational integrity for LNG, FSRU, STS and offshore systems.

  • LNGC / FSRU operational interface monitoring
  • Supervision of transfer operations
  • Follow-up of critical systems & equipment
  • Failure or anomaly identification
  • Operational deviation tracking
  • Corrective action management
  • Repair & maintenance follow-up
  • Post-repair testing verification
  • Return to Service condition verification
  • Technical closure of findings
  • Lessons Learned & recurrence prevention

Systems & equipment covered

Emergency Shutdown Systems (ESD)Emergency Release Systems (ERS/ERC)Cryogenic hosesLNG loading armsTransfer pumpsValvesVapour return systemsMooring systemsWinchesFendersFirefighting systemsShip-to-ship communicationsInstrumentationSafety-critical equipment
The concept is not to replace the shipowner, manufacturer, operator or classification society, but to provide an additional independent technical verification.

03 · Maritime Safety Management Services

Distinct from HSEQ — focused on the Safety Management System

This line is clearly differentiated from HSEQ because it relates directly to Maritime Safety and the Maritime Safety Management System.

Specialized profiles available: Maritime Safety Advisor / Maritime Safety Responsible Personnel.
  • Maritime Safety Management System implementation
  • Maritime Safety Compliance Monitoring
  • Follow-up of maritime safety policies & procedures
  • Deficiency identification
  • Operational Safety Verification

  • Emergency Preparedness, Drills & Exercise Coordination
  • Contractor follow-up
  • Safety KPI Monitoring & Management Reporting
  • Continuous Improvement & Compliance Monitoring
04 · LNG & Marine Operational Risk

Risk analysis integrated with real operations

Dedicated to the analysis and management of risk associated with LNG, FSRU, STS, offshore and marine terminal operations — not limited to documentary studies.

  • HAZID
  • HAZOP Support
  • Bow-Tie Analysis
  • QRA Support
  • LNG Transfer & STS Risk Assessment
  • SIMOPS Risk Assessment
  • Mooring Risk Assessment
  • Navigation & Marine Risk
  • Gas & Explosion Risk
  • Barrier Management

05 · Regulatory & Operational Readiness

Technical & documentary preparation ahead of operations

Greenport supports clients in technical and documentary readiness before the start of operations and ahead of inspections or regulatory verifications — for Colombia, including support related to DIMAR Resolution 0250 of 2026.

  • Regulatory Gap Assessment
  • Resolution 0250 Compliance Review
  • Operational Readiness Review
  • Pre-operation Audits
  • Procedure & Checklist Verification
  • Documentation & Transfer Readiness
  • Emergency Readiness
  • Pre-DIMAR Readiness Reviews

06 · Safety & Operational Performance Management

Beyond safety cards: safety and operational performance, integrated

This line integrates both safety and operational performance into a single system — digitized through the Greenport Marine Assurance Dashboard (GMAD).

Safety Observation & Behavioral Program

Records observation types including:

Safe BehaviorsUnsafe BehaviorsUnsafe ActsUnsafe ConditionsNear MissesPositive ObservationsEnvironmental ObservationsStop Work InterventionsHSE FindingsContractor ObservationsBarrier Failures

Each observation captures: Category · Risk Level · Responsible Person · Target Date · Corrective Action · Evidence · Status · Closure Date.
