On a calm day in port, STI Carnaby looks almost relaxed, white superstructure above a deep-red hull, but the 183-meter product tanker is a working tool that earns money with every ton of clean fuel it moves across the oceans.

What STI Carnaby is built for

STI Carnaby is a MR product tanker with around 50,000 deadweight tons, designed to carry refined products like gasoline, diesel, and jet fuel in coated cargo tanks.

The vessel belongs to Scorpio Tankers’ IMOIIMAX-type subgroup, optimized for flexibility and fuel efficiency on global clean-product trades between Europe, the Americas, the Middle East, and Asia.

Design details you do not see from the quay

Below deck, multiple segregated tanks and advanced pumping systems let the crew handle different cargoes in parallel, reducing port time and boosting earning days.

The hull form and propulsion system are tuned for economical speeds around 12-14 knots, where fuel burn and emissions per ton-mile stay competitive in a market obsessed with operating costs.

Environmental tech on board

STI Carnaby is fitted with an exhaust gas cleaning system, a scrubber, so it can burn high-sulfur fuel oil while still complying with the IMO 2020 sulfur cap.

A modern ballast water treatment system helps prevent the spread of invasive species when the ship loads and discharges ballast in different regions, a small but crucial piece of global environmental regulation.

How the ship earns its keep

Commercially, STI Carnaby can serve both spot voyages and time-charter contracts, depending on how Scorpio Tankers positions its fleet in the current freight cycle.

In a strong market for medium-range tankers, daily time-charter equivalents for such ships can climb into the mid five figures in US dollars, turning every additional day at sea into meaningful cash flow.

Life on a modern product tanker

For the crew, the ship feels like a self-contained industrial platform: engine vibrations in the deck plates, constant hum of generators, the cold of refrigerated cargo lines against warm sea air.

Bridge electronics, ECDIS navigation, and engine-room automation mean fewer people can safely run more complex systems than on older tonnage, but training and procedures have to keep pace.

Why this vessel matters to investors

Scorpio Tankers highlights the youth and fuel efficiency of its MR fleet as a competitive edge, and ships like STI Carnaby are what underpins that claim in fleet lists and investor presentations.

Compared with older vessels, a modern MR with scrubber and efficient hull can command better charter terms and be more attractive to charterers focused on emissions and fuel bills.

Where Scorpio Tankers stands on the market

Scorpio Tankers operates one of the world’s largest fleets of product tankers, with a focus on MRs and LR2s, tightly linked to global demand for refined oil products and trade dislocations.
