Stena Bulk Brand Guidelines: A 1982 Gothenburg Tanker Company Inside the Stena Sphere

A tanker company inside a family group.

Stena Bulk was founded in 1982, as both the company and English Wikipedia’s article on the Stena Sphere record; Swedish Wikipedia dates the group’s move into bulk shipping to the same year. It grew inside a larger family business. English Wikipedia traces the Stena Sphere to 18 November 1939, when Sten A. Olsson founded the trading company Sten A. Olsson Metallprodukter, now Stena Metall. He bought his first vessel in 1946, and at the beginning of the 1960s the business started a ferry service between Gothenburg and Skagen in northern Denmark, the start of what is now Stena Line.

The group divided into Stena Line and Stena Metall in 1972, invested in offshore and RoRo vessels in the late 1970s and added property in 1980, according to the same article. Stena Bulk followed in 1982. The ship-management company Northern Marine Group was founded in 1983, the year Dan Sten Olsson took over as chief executive, and the listed tanker company Concordia Maritime followed in 1984. English Wikipedia describes the Stena Sphere as three parent companies, Stena AB, Stena Sessan and Stena Metall, wholly owned by the Olsson family and together one of Sweden’s largest family-owned corporate groups, and it lists Stena Bulk AB among the subsidiaries of Stena AB.

Stena Bulk says it is part of a sphere of about 22,000 employees working in shipping, offshore, real estate and recycling, and that it draws on other Stena companies for shipbuilding, crew management and financing. Its press release of October 2026 gives the group as more than 19,000 employees. The company places itself among the major tanker shipping companies worldwide.

Ship designs with a MAX suffix.

Stena Bulk’s identity rests on ship design as much as on cargo. The company says it designs and builds its own vessels in cooperation with Stena Teknik, the group’s technical department, which handles new-building and conversion projects as well as research and development. It names its designs with a “MAX” suffix: the IMOIIMAX product and chemical tanker; the IMOFlexMAX, which it describes as a next-generation development of that design built around flexibility and efficiency; and the InfinityMAX, a hybrid bulk-carrier concept meant to carry both dry and wet cargoes in modular compartments.

The company describes its business as the global sea transport of crude oil, refined petroleum and renewable products, organised in three areas: crude and fuel, products and chemicals, and intermediate tankers. Its fleet page in November 2026 lists 59 vessels across Intermediate, Suezmax, Medium Range and Flexi classes, among them the Suezmaxes Stena Suede and Stena Superior, both built in 2011, and a series of Suezmaxes carrying Sonangol names. It gives its team as 95 shore-based employees and 300 crew members at sea, with offices in Gothenburg, Houston, Copenhagen, Dubai and Singapore. Its own line for the work is that “oil should always travel first class.”

Joint ventures have shaped its growth. In March 2017, according to a release published on Cision, Stena Bulk agreed to buy the remaining 50 percent of Stena Weco, a product and chemical tanker company it had owned jointly with Denmark’s WECO Shipping since early 2011; Stena Weco then ran about 65 vessels from its head office in Denmark. On 27 January 2026 Stena Bulk announced that it had bought an additional shareholding in Golden Stena Baycrest Tankers from Bay Crest and become majority shareholder in the joint venture, which remains owned by Stena Bulk, Golden Agri and Bay Crest and operates from Singapore and Dubai.

How tanker owners present themselves.

Tanker owners rarely sell to the public, so their brands live mostly on corporate websites, in investor material and on the ships themselves. The pattern is consistent across the companies in this series: a short purpose line, a fleet page, an investor section and a sustainability page, set in restrained corporate type and colour. The palettes in these guides, from navy and steel to deep sea greens, are tones of our own choosing rather than any company’s colours.

Photographs do much of the work. Owners publish photographs of their own crude and product tankers, and Ardmore Shipping’s homepage, for example, pairs its values with pictures of named ships from its fleet. The ship names themselves often carry the identity: Ardmore puts its own name on every hull, while Okeanis names its tankers after Greek islands.

The fleet list is the core document. Companies set out their ships by size class, from Medium Range (MR) and Handysize product tankers to Suezmax and VLCC crude carriers, usually with the year built, the shipyard, the deadweight and the flag, and they list newbuildings on order with expected delivery dates. Pages on pools, chartering arms and ship-management partners explain who markets and runs the ships commercially and technically.

Many of these companies are listed, so investor pages sit close to the top of the menu: press releases, quarterly results, presentations, filings with regulators and share data, sometimes for two stock exchanges at once. ESG and sustainability reports, often published once a year and prepared with reference to named reporting frameworks, complete the picture. This guide sets out what each company’s own pages and dated independent sources show about its history, ownership and fleet, and keeps the company’s own claims marked as its own.

Back under the Swedish flag.

Since 2025 the company has been moving ships onto the Swedish register. MarineLink reported on 14 July 2025 that Stena Bulk was in the final stage of a plan to reflag five Suezmax tankers to Sweden, which at the time had no Suezmax tankers on its register, and that the first, Stena Sunrise, was due to change flag in Singapore at the end of that July. Reforms including the removal of stamp duty on ship registration, a more competitive tonnage tax and an improved ship register had prepared the ground, the report said. On 12 October 2026 MarineLink reported the fourth and fifth reflaggings: the Suezmax Stena Superior in Shenzhen, China, and the 49,690-dwt product and chemical tanker Stena Imperator, built by Guangzhou Shipbuilding International and delivered in 2017, the first ship of the IMOIIMAX design to join the programme, in San Francisco.

Stena Bulk is led by Erik Hånell, its president and chief executive, and sits in the Stena AB part of the group alongside Stena Line, Stena Drilling, Stena RoRo and Stena Teknik, English Wikipedia says. The Stena name is shared across all of them, which matters for anyone looking up the company: stenabulk.com is the tanker company’s site, stena.com covers the wider group and stenaline.com the ferry business.

For a design guide, Stena Bulk shows how a tanker company can build an identity on named ship designs and a group name shared with ferries, drilling and recycling; compare Frontline, which also began in Sweden, and Maersk Tankers, a Scandinavian tanker name with a long family history. For this guide we use navy, signal red and steel grey with a condensed sans, an unofficial interpretation; no product or logo is reproduced.
