Marine Solver
Fleet Intelligence & Planning
Pre-fixture decision optimization for voyage chains, cargo combinations, contractual obligations and fleet coverage.
Marine Solver explores the commercial decision space before a fixture is made. It evaluates feasible vessel-cargo-route combinations, builds and ranks optimized scenarios, then analyzes their time, cost, profit and environmental performance.
Marine Solver combines voyage solver and voyage chain solver capabilities with pre-fixture fleet planning, helping commercial teams build, optimize and compare multi-leg Voyage Chains, vessel–cargo assignments and fleet-deployment scenarios before fixture.

Core concept
From Decision Space to Decision Scenarios
Marine Solver starts before voyage analysis. Define the fleet, cargo opportunities, business objective and constraints. The optimization engine searches the feasible combinations and returns transparent alternatives for commercial decision-making.

Four planning modes
One optimization engine. Four different commercial questions.
Marine Solver changes the mathematical decision space to match the planning problem — from full-load employment to multi-cargo allocation, contractual liftings and fleet-wide transportation-program coverage.
Sole Cargo
Find the strongest vessel employment and Voyage Chains
Search full-load cargo opportunities for one or several vessels while accounting for open positions, laycans, freight, ballast, future positioning and voyage-chain logic.
- Planning Horizon or Target Chain mode
- Single voyage or multi-leg Voyage Chain
- Fixed assignments, exclusions and mandatory cargoes
- Exit Point and target-region positioning logic
Part Cargo
Build feasible cargo combinations, sequences and distributions
Optimize multi-cargo voyages where commercial attractiveness and physical placement must work together across ports, onboard cargo and vessel-space constraints.
- Ballast, onboard-start and discharge-sequencing modes
- Tank / hold allocation and cargo compatibility
- AND / OR / MUST / vessel-space rules
- General Cargo dimensions, tiers and OnTop logic
COA
Optimize how contractual lifting obligations are covered
Plan mandatory liftings across the available fleet while preserving commercial flexibility and integrating spot opportunities where they strengthen the chain.
- Mandatory contractual liftings
- Fleet assignment across the planning horizon
- Spot cargo integration between commitments
- Contract execution and fleet-utilization scenarios
Trader Fleet
Optimize transportation-program coverage across the fleet
Evaluate the full program at fleet level: which cargoes can be covered, which vessels should be assigned, what remains uncovered and where repositioning is required.
- Fleet coverage instead of isolated voyage selection
- Flow-based cargo program generation
- Uncovered-opportunity analysis
- Follow-up fleet repositioning strategy
Optimization criteria
Define what “optimal” means
The same vessels and cargoes can produce very different plans depending on the commercial objective. Marine Solver lets the user define the priority before the decision space is explored.
Minimize Cost
Reduce total voyage-chain operational cost across ballast, fuel, ports, waiting, canals and regulatory exposure.
Maximize Profit
Search for the strongest net commercial outcome while balancing freight income, voyage costs and positioning.
Minimize Non-Productive Time
Reduce ballast, waiting and idle exposure across the Voyage Chain and fleet plan.
Minimize Emissions
Search for feasible scenarios with the lowest total CO₂ footprint under the selected operating assumptions.

Daily Profit Floor

Control & constraint layer
Optimization is controllable — not a black box
Users define the commercial rules and flexibility of the problem. The engine searches inside that controlled feasible space instead of hiding assumptions behind one unexplained answer.
Laycan & Timing
- Strict laycan or configurable deviations
- Berth / queue arrival logic
- Ignore Laycan for exploratory scenarios
- Safety Buffer before cancelling
- Planning Horizon and Target Chain controls
Cargo & Vessel Logic
- Mandatory cargoes and fixed assignments
- AND / OR cargo grouping
- Vessel include / exclude rules
- Cargo compatibility and placement constraints
- Onboard and previous-cargo logic where applicable
Geography & Routes
- Dynamic route calculation
- Suez, Panama, Kiel and Turkish Straits cost logic
- Route-avoidance and piracy-sensitive routing
- SECA/ECA and EU-port detection
- Port ambiguity resolution and expandable port pool
Environmental & regulatory intelligence
Commercial and environmental optimization in one decision space
Environmental performance is not added only after optimization is finished. Marine Solver brings emissions, regulatory costs and environmental targets into pre-fixture planning so their commercial consequences are visible before commitment.
Fuel choice, route geography, Voyage Chain structure, vessel utilization and fleet positioning can change both economics and environmental exposure. Marine Solver evaluates these effects together rather than as separate reports.
Scenario output & analysis
Find the plan — then understand why it is stronger
Marine Solver does not end at the objective value. Each selected scenario becomes a complete analytical result that can be reviewed, compared and recalculated.
Up to five optimized scenarios
Compare alternative Voyage Chains, vessel assignments and fleet plans instead of relying on one opaque answer.
Operational schedule & timeline
Review ballast and laden legs, loading and discharge operations, waiting, port calls and complete chain timing.
Commercial & environmental breakdown
Cost, profit, TCE, Cost/Day, emissions and compliance metrics at scenario, vessel and cargo level.
What-if re-optimization
Change selected assumptions and test how the preferred strategy changes with market or operating conditions.
Solver or Analyzer?
Start at the right point in the decision process
Both products provide detailed voyage intelligence. The difference is where the decision process begins.
Need the system to find the Voyage Chains or fleet plan?
Define the fleet, cargo decision space, objective and constraints. Marine Solver searches feasible vessel-cargo-route combinations, constructs optimized alternatives and then analyzes their commercial, operational and environmental performance.
Book a DemoAlready have the Voyage Chains you want to compare?
Enter up to three planned Voyage Chains and calculate their voyage P&L, TCE, schedule, emissions, EU ETS, CII and FuelEU Maritime metrics without asking the system to select or optimize the sequence for you.

FAQ
Marine Solver questions
Is Marine Solver a voyage solver?
It includes voyage-solver and voyage-chain-solver functionality, but the platform is broader. Marine Solver is a pre-fixture fleet planning engine that can search Voyage Chains, cargo combinations, contractual execution plans and fleet-coverage scenarios within one decision framework.
Can Marine Solver build Voyage Chains automatically?
Yes. In the relevant planning modes, the engine evaluates feasible cargo and vessel sequences and constructs optimized Voyage Chains under the selected objective, laycan logic, route assumptions and constraints.
Can it optimize several vessels and cargoes at the same time?
Yes. Marine Solver is designed for system-level planning where vessel assignment, cargo selection, timing, positioning and commercial constraints interact across the same optimization problem.
Does Part Cargo include cargo allocation and stowage logic?
Yes. Part Cargo can evaluate cargo combinations together with tank or hold feasibility, onboard cargo, compatibility, placement restrictions and alternative distribution plans.
How are COA and Trader Fleet different?
COA focuses on how mandatory contractual liftings can be covered efficiently while integrating spot opportunities. Trader Fleet starts from a wider transportation program and asks how effectively the available fleet can cover it.
Does Marine Solver include EU ETS, CII and FuelEU Maritime?
Yes. The environmental layer includes CO₂ emissions, EU ETS exposure, SECA/ECA-aware voyage logic, CII/AER performance and FuelEU Maritime metrics. Environmental objectives and constraints can influence which scenarios are considered stronger or feasible.
Does Marine Solver replace the commercial decision-maker?
No. Marine Solver is a decision-support system. The engine expands and evaluates the feasible decision space, while the user defines objectives, constraints and business context and remains responsible for the final commercial decision.
