Capabilities · Marine transportation
Tugboat and barge operations shaped around cargo and charter requirements.
Castbay Marine coordinates cargo, vessel allocation, voyage planning, port requirements, and execution through one practical operating model.
Indonesia · Charter-based · Operationally flexible
Our capability model
Every movement begins with the cargo, the charter commitment, and the operating environment.
Fleet deployment is not based on fixed liner routes. It follows customer requirements, cargo-owner needs, scheduling, vessel availability, and operational feasibility.
Our role is to translate those requirements into a workable tugboat and barge movement across Indonesia.
Core operations
Marine transportation built around paired tugboat and barge units.
Castbay Marine owns six tugboat and barge sets, with each operational unit consisting of one tugboat paired with one barge.

Supporting services
Coordination that supports the movement from planning through completion.
Supporting activities are presented as part of marine transportation execution, not as separate vessel classes or unsupported service lines.
Charter arrangement
Commercial and operational coordination aligned with cargo, route, schedule, and vessel availability.
Cargo coordination
Alignment between cargo owners, charterers, vessel teams, ports, and other operating stakeholders.
Voyage planning
Planning based on cargo profile, operating route, port conditions, schedule, and charter commitments.
Port coordination
Coordination required for vessel calls and cargo movements at Indonesian commercial ports.
Marine logistics
Practical coordination of vessels, cargo, schedules, ports, and supporting parties during execution.
Operating flow
From cargo requirement to completed marine movement.
The operating sequence remains flexible because each assignment depends on its charter, cargo owner, route, schedule, and available fleet position.
Cargo requirement
Understand the cargo owner, cargo type, volume, destination, timing, and charter requirement.
Operating plan
Review route, port conditions, scheduling, commercial commitments, and operational feasibility.
Vessel allocation
Assign an available tugboat and barge set suited to the agreed movement and operating schedule.
Port coordination
Coordinate the operational interfaces required at origin, destination, and along the voyage.
Marine transportation
Execute the movement according to the agreed charter and operating plan.
Completion
Complete the assigned cargo movement and close the operational cycle with the relevant parties.
Cargo experience
Operational experience across mineral and bulk cargo movements.
