Truck to vessel bunkering for fast and flexible fuel supply

May 12, 2026

At Royal Petroleum, we have supported truck to vessel bunkering for over 25 years. We understand how port calls actually work on the island, where timing, access, and execution determine whether your operation stays on schedule or falls behind.

Port infrastructure alone does not guarantee efficiency. When a vessel depends on barge availability or terminal access, delays are common. That is why we operate differently. We deliver fuel directly to your vessel, eliminating unnecessary waiting time at port.

What is our truck to vessel bunkering service used for?

Traditional bunkering often requires repositioning your vessel to a specific terminal, adding time, coordination, and cost. Our truck-to-vessel operation removes that dependency by bringing the fuel directly to your berth.

Versatility across ports. Not all locations in Puerto Rico have barge infrastructure. Because we operate our own fleet, we can supply fuel where other methods are not viable. We operate at all major ports in Puerto Rico, including San Juan, Ponce, and other points throughout the island.
Urgent refueling. Schedule changes, weather conditions, or operational delays can require immediate fuel supply. With direct access to product and full control over dispatch, we position units quickly to support last-minute requirements without relying on third parties.
Support for working vessels. Service vessels, tugboats, and support fleets depend on a continuous supply of fuel. We deliver directly while crews manage cargo, provisions, or rotations, avoiding interruptions to ongoing operations.

How our truck to vessel bunkering works

Executing bunkering at the dock requires coordination, experience, and technical control. Our operations follow a structured process designed to avoid delays and ensure safe transfer.

Scheduling. We coordinate with port authorities in Puerto Rico and your maritime agent to align access, permits, and delivery timing with your berthing window.
Safety checks. Before any transfer begins, we secure the area, inspect the vessel’s manifold, and follow strict safety procedures in accordance with federal and local requirements.
Fuel & lubricants transfer. Once cleared, pumping begins immediately. Our equipment is designed to handle different volumes efficiently while maintaining constant communication between our operator and your chief engineer. We supply Marine Gas Oil (MGO) and marine lubricants from recognized manufacturers, ensuring product integrity throughout the operation.

Why choose Royal Petroleum’s truck to vessel bunkering

In Puerto Rico, execution speed is not defined by access to fuel, but by how efficiently it can be delivered.

Advantages

Operational speed. Pumping rates are calibrated between 100 and 1,000 gallons per minute, depending on vessel capacity and safety parameters. Fueling then begins as soon as the vessel is ready and the area is secured, avoiding dependency on terminal schedules or barge availability. With our own fleet and pumping equipment, we handle high-volume deliveries efficiently while adapting to each vessel’s operational requirements.
Full control over delivery. Because we operate our own fleet and pumping equipment, we control dispatch, routing, and execution. This allows us to respond quickly and adjust to operational changes without external delays.
Cost efficiency. Compared to barge-based bunkering or terminal repositioning, truck-to-vessel operations reduce unnecessary vessel movements within the port. This helps avoid additional costs such as tug assistance, pilotage, and waiting time associated with barge scheduling, resulting in a more efficient and economical fueling process.
Access across Puerto Rico ports. We supply at all major ports across the island, allowing vessels to bunker without depending on limited infrastructure or specific terminals.

Secure your fuel supply at the port with our truck to vessel bunkering service

Time at port should be used for operations, not for waiting on fuel logistics. With direct truck to vessel bunkering service, your vessel can refuel without disrupting its schedule.

At Royal Petroleum, we coordinate each delivery based on your operational window and execute directly at your berth. If your vessel is calling Puerto Rico, our team can align your fuel supply in advance and ensure a smooth operation.
