ORLEN Opens Gdansk Marine Terminal as Diesel Margins Remain Well Above Pre-March Levels
Poland's ORLEN has commissioned a 1.8-million-tonne river terminal in Gdansk for marine gas oil and biofuel distribution, as diesel margins run $19-$26 per barrel above pre-March levels.
ORLEN SA put a marine transshipment terminal into service on Wednesday (2026-08-05) on the Martwa Wisła River adjacent to its Gdansk refinery, giving the Polish company its first direct vessel-loading point for marine gas oil at the site. First vessels have already called: some loaded marine gas oil from the refinery; others delivered fatty acid methyl ester for use in biofuel production, ORLEN said.5
The facility is designed to handle more than 1.8 million tonnes of cargo annually, covering both inbound crude feedstock and outbound oil products. The project cost nearly PLN 500 million ($133.99 million) and was built largely by Polish companies. Eliminating intermediate transport between supply and the waterway was a central design objective, ORLEN said.5
The launch coincides with elevated distillate margins. In a June 2026 research note, Goldman Sachs forecast that the Middle East conflict had pushed overall refining margins two to three times above their 2013-to-2019 average, with diesel margins running $19 to $26 per barrel above pre-March levels, Reuters reported. ICE Brent crude front-month was trading at $80.63 per barrel as of Wednesday (2026-08-05), with NYMEX heating oil front-month at $3.80 per gallon.2
The distillate supply strain traces to the Strait of Hormuz. In its June 2026 Short-Term Energy Outlook, the EIA assumed the strait would remain effectively closed in the near term, with oil shipments resuming only in the third quarter of 2026. Three crude tankers carrying a combined 6 million barrels of Gulf crude exited the strait in May 2026 with tracking systems switched off, shipping data from Kpler and LSEG released on Monday (2026-05-18) showed — an indication of the routing contortions the closure imposed on physical markets.3,1
Marine gas oil is a diesel-grade distillate used as bunker fuel aboard vessels. Direct river loading at the refinery gate reduces handling costs and cuts the product's path to Baltic ports and export markets. FAME delivered inbound to the terminal feeds the refinery's biofuel blending operations. Both product streams benefit from elevated distillate values as the Hormuz closure keeps alternative supply routes expensive.5,2
Goldman Sachs also warned that diesel and gasoline inventories would likely decline further during any initial Hormuz reopening, as pent-up tanker demand absorbed available product before spot markets could rebalance. The bank anticipated the initial reopening phase would squeeze stocks further before replenishment flows caught up. Refiners with low-cost, flexible logistics, including direct river-to-sea access, stand to capture a larger share of that window.2
But a separate disruption in the Red Sea kept Atlantic routing under pressure throughout the same period. Tankers carrying Saudi crude to India and China respectively made U-turns in the Red Sea in July 2026 (2026-07-21) after Yemen's Houthis declared a naval blockade against Saudi Arabia, shipping reports showed. That added Atlantic-basin uncertainty on top of the Gulf supply shock.4
Alongside the terminal, ORLEN disclosed it holds rights to develop a 180 megawatt solar photovoltaic farm and a 36 megawatt wind farm located approximately 8 kilometers apart, described as part of one of Poland's largest onshore renewable energy clusters with a combined capacity of 485 megawatts. No commissioning date was given.5
Hormuz cargo flow timing is the variable most likely to shape the terminal's near-term commercial case. Goldman Sachs's June 2026 analysis suggested diesel stocks would fall further during an initial strait reopening, as rerouted tanker flows take time to normalize, meaning the margin environment that currently underpins ORLEN's new capacity may tighten further before it eases.2,3
