Practical Innovation for Cleaner Tugboat Operations
Could green methanol work for your tugboat?
Understand the retrofit requirements, investment scenarios and operating implications before committing to a conversion.
Marisol Globe’s Green Methanol Feasibility Model (GMFM) brings the key considerations together in a vessel-specific assessment. It helps owners understand what a potential retrofit could involve before committing to detailed engineering or investment.
The model has been applied in a completed feasibility study of OMIDAN 4, using costs and market conditions relevant to the Netherlands. It supports a decision to proceed, revise the concept or consider alternatives.
Marisol Globe provides integrated green methanol retrofit feasibility assessments and project advisory services for tugboat owners, port operators and maritime organizations. Our Green Methanol Feasibility Model (GMFM) brings technical, operational, financial, safety and environmental considerations together to support real-world decisions on converting existing tugboats to methanol fuel.
Instead of treating fuel transition as a single engineering or cost question, we evaluate the vessel as a complete operating system: its machinery, onboard arrangements, duty cycle, fuel supply, investment requirements and emissions implications, to determine whether a retrofit is feasible and commercially sensible under defined assumptions.

Real Case
From Research to Real-World Application.
-
The completed OMIDAN 4 assessment evaluated the technical retrofit requirements, economic viability, operational considerations, safety requirements, environmental impact, and investment scenarios associated with a potential transition to green methanol.
-
By incorporating vessel-specific technical data and market conditions relevant to the Netherlands, GMFM demonstrates its practical application beyond academic research.
-
The completed assessment provides a structured basis for informed investment decisions and future green methanol retrofit initiatives in the Dutch maritime sector.

About
Maritime experience with a forward-looking purpose.
Marisol Globe is a Netherlands-based business founded on Mohammad Kargar’s experience in marine engineering and industrial inspection. Its work connects practical surveying and quality assurance with a focus on the maritime energy transition.
GMFM originated in his master’s research in the Netherlands and has been applied to a real-vessel feasibility study.

Practical Innovation for Cleaner Tugboat Operations
Marisol Globe provides integrated green methanol retrofit feasibility assessments and project advisory services for tugboat owners, port operators and maritime organizations. Our Green Methanol Feasibility Model (GMFM) brings technical, operational, financial, safety and environmental considerations together to support real-world decisions on converting existing tugboats to methanol fuel.
Instead of treating fuel transition as a single engineering or cost question, we evaluate the vessel as a complete operating system: its machinery, onboard arrangements, duty cycle, fuel supply, investment requirements and emissions implications, to determine whether a retrofit is feasible and commercially sensible under defined assumptions.
What We Assess
See the dependencies before making the investment.
Each assessment considers the vessel as an operating system, under clearly defined assumptions.
-
Technical retrofit feasibility
Engine and fuel-system compatibility; fuel storage and piping; onboard space; ventilation, fire protection and safety-related changes.
-
Economic feasibility
Retrofit investment (CAPEX), fuel and operating costs (OPEX), lifecycle economics, cost sensitivities and investment scenarios using relevant Netherlands-market assumptions.
-
Operational readiness
Vessel duty cycle, fuel demand, range, bunkering logistics, availability of methanol and implications for day-to-day tugboat operations.
-
Safety and regulatory considerations
Applicable technical standards, classification considerations, fuel safety requirements and project-specific compliance pathways.
-
Environmental impact
Scenario-based comparison of greenhouse-gas emissions and the potential benefits of lower-carbon methanol pathways, including the influence of fuel production and supply chain.
-
Implementation pathway
Retrofit scope, key risks, information gaps and practical next steps for engineering, budgeting and project development.
Process
A structured path to a better-informed decision.
-
Vessel Data
Understand the vessel, its operating profile and objectives.
-
Technical & Economic Assessment
Review technical, economic, operational and safety factors.
-
Scenario Comparison
Compare relevant options and assumptions.
-
Feasibility Report

ApplicationGreen methanol retrofit feasibility
Market contextNetherlands-relevant costs and conditions
Completed workTechnical and economic scenario assessment
From research to practical decision support.
GMFM was applied to OMIDAN 4 to examine vessel-specific retrofit requirements and compare technical and economic scenarios. This is an application of the assessment model to a real vessel.
GMFM has already been applied in a completed feasibility assessment of the real tugboat OMIDAN 4. The case examined the vessel-specific retrofit requirements and compared technical and economic scenarios using costs and market conditions relevant to the Netherlands. This real-vessel application demonstrates how the model can translate complex fuel-transition questions into structured, decision-ready assessments.

Partners
Working with tugboat owners and maritime organizations
Marisol Globe is engaging with tugboat owners and relevant organizations on potential green methanol conversion projects, including ongoing consultations and commercial discussions.
Our advisory approach covers the project from initial vessel screening and feasibility through to defining the requirements and next steps for a potential retrofit. Physical conversion work, where pursued, would be a separate engineering and implementation phase.
