Understand How Ships Are Fueled And The Complexity Of This Essential Operation For Maritime Trade.
Let’s talk about an essential topic that is often overlooked: how ships are fueled. Have you ever wondered how these giants of the sea receive the fuel needed for their long journeys? Today, we will dive into this fascinating operation filled with details.
For those who have never thought about it, fueling a ship is nothing like filling the tank of your car. We are talking about thousands of tons of fuel, complex operations, and impressive logistics. Let’s take the Port of Paranaguá as an example, one of the largest and busiest in Brazil. Here, the movement of ships is constant, and the fueling operation is just one part of the hectic daily routine of the port.
How Ships Are Fueled
Look, when we talk about how ships are fueled, we need to understand that there are several types of vessels and methods. In the case of a common cargo ship, the operation generally involves a fuel barge. These barges are towed to the ship, as they do not have their own propulsion. The tug positions the barge alongside the ship, and through hoses (long specialized hoses), the fuel is transferred.

Petrobras completes 1,300 hours of work and 15 km of subsea lines to connect the Búzios 90 well to the P-79 — the platform is ready to produce 180,000 barrels per day and is just awaiting ANP approval.

Four 24-meter suction sails that generate up to 7 times more lift than traditional sails have been installed on a Maersk oil tanker. The autonomous system can reduce consumption by up to 20% and is already recording savings of up to 5.4 tons of fuel per day at sea, with annual cuts potentially reaching thousands of tons on a single vessel.

After the announcement of US$ 2 billion for six PSVs, Petrobras may order four RSV vessels in Navegantes in April, with the BID published and Navship mentioned, but awaiting the release of funds.

Named after the province closest to Taiwan, China’s third aircraft carrier weighs 80,000 tons, carries 50 stealth aircraft, and uses electromagnetic catapults that launch 12 fighters per hour.
The operation is not just plug and play; there is a whole preparation. Before starting the fueling, a containment barrier, known as an Oil Boom, is placed around the ship. This barrier serves to prevent any oil spills from spreading into the sea in case of a leak, avoiding environmental disasters. At the Port of Paranaguá, for instance, the most commonly used marine fuel is MF 380, supplied by Transpetro.
The Reality At The Port Of Paranaguá
The scene is impressive. Leandro [from the video above] was aboard a tugboat, recording a report, and was able to closely observe the operation of a cargo ship. The dimensions and logistics involved are jaw-dropping. Just imagine, while a truck carries between 10 and 15 tons, a bulk carrier transports between 50,000 and 68,000 tons of cargo in a single trip! This shows the scale of the challenge of how ships are fueled.
During the visit, the YouTuber saw a ship unloading with its holds open and another being fueled. Everything happens simultaneously, a symphony of machines and workers coordinating every movement.
It’s Not Just A Matter Of Filling Tanks
How ships are fueled is an operation that requires precision, technology, and great care. It is not just a matter of filling tanks, but rather ensuring that the fuel reaches its destination without harming the environment. At the Port of Paranaguá, this operation is performed with impressive efficiency, ensuring that maritime trade continues to flow without interruptions.
So, the next time you see a cargo ship at the port, remember the complex ballet that happens behind the scenes to keep these giants moving. Stay tuned for more stories and curiosities from the maritime world!
