Petrolink Energy (trading through PTL) is a Hong Kong-based marine fuel bunkering facilitator that arranges fuel supply for vessel operators across the Asia Pacific region. Petrolink does not own or deliver fuel itself — it acts as an intermediary, aggregating demand from customers, purchasing marine fuel from suppliers, and arranging for suppliers to deliver directly to customers' vessels at port. Fuel products include low-sulfur fuel oil, high-sulfur fuel oil, and marine gas oil, primarily serving container ships, bulk carriers, general cargo vessels, and chemical tankers. Petrolink earns a spread between the price it pays suppliers and the price it charges customers. The model relies on aggregating demand to secure bulk pricing from suppliers, then passing on competitive rates while retaining a margin. Petrolink also differentiates by extending trade credit to customers — a key purchase criterion in bunkering — while managing the gap between supplier payables and customer receivables. Petrolink holds no inventory; fuel passes directly from supplier to customer, though Petrolink bears brief ownership risk during transfer. The business is highly working-capital intensive, and access to capital directly constrains how much volume Petrolink can write. The company supplies roughly 130,000–165,000 metric tons annually and operates with just 11 employees. Petrolink is pursuing two growth avenues: geographic expansion into Southeast Asia via a Singapore subsidiary, and acquiring bunkering tankers to become a physical fuel supplier, which management expects would widen margins. Petrolink also added a nascent trade finance business in early 2026 through the acquisition of Twocap, though this segment is not yet material.
