Stena Bulk

What Stena Bulk does

Stena Bulk AB is a privately held Swedish tanker shipping company and a wholly-owned subsidiary of the Stena Sphere family conglomerate, headquartered in Gothenburg with regional offices in Houston, Copenhagen, Dubai, and Singapore. The company operates a combined fleet of approximately 60 vessels totaling roughly 4.5 million DWT across three business areas: Crude & Fuel (self-designed Suezmax tankers), Products & Chemicals (Medium Range and IMOIIMAX tankers), and Intermediate Tankers (chemical and specialised vessels under 25,000 DWT). Its core technology differentiator is in-house vessel design capability — IMOIIMAX tankers with 18 cargo tanks and nitrogen inert gas systems, self-designed Suezmax hulls delivering up to 15% lower bunker consumption, and IMOIIMeMAX methanol-fuelled 49,900 DWT MR tankers developed jointly with Proman, positioning the company ahead of IMO emissions regulations and toward its stated net-zero 2050 target.

Revenue is generated through time charter contracts, voyage charters, and joint-venture pool operations. Three core pools underpin scale economics: the Stena Sonangol Suezmax Pool (~20 vessels with Sonangol), GSB Tankers J19 and ACTA pools in Asia and the Middle East (now majority-owned after the January 2026 share acquisition from Bay Crest), and the Proman Stena Bulk methanol JV. Customers include major international oil companies, national oil companies (Petrobras, NNPC Shipping), integrated energy majors (ExxonMobil), and chemical/agricultural shippers. Pricing is negotiated privately per voyage based on market rates, vessel type, cargo, and route specifics and is not publicly disclosed. Distribution is direct B2B through owned chartering desks across the five global offices. Strategic positioning emphasizes fuel-efficient proprietary designs, sustainability leadership (GREEN4SEA Tanker Operator Award 2017; Lloyd's List Global Awards 2016), and an expanding footprint into LNG infrastructure via the September 2025 exclusive jettyless LNG technology partnership.
