Korean Register Brand Guidelines: A 1960 Class Society, a Blue Circle & Busan

Founded in June 1960.

Korean Register, known as KR, is South Korea’s ship classification society. It was founded on 20 June 1960 as the Korean Register of Shipping, a non-profit incorporated association set up with the permission of the Maritime Affairs Administration, Korean Wikipedia says. Its first chairman was Heo Dong-sik, a graduate of the first navigation class of Korea Maritime University. English Wikipedia calls KR a not-for-profit classification society offering verification and certification for ships and marine structures in design, construction and maintenance.

The early milestones on KR’s own timeline are about recognition abroad. In August 1966 it signed a reciprocal work agreement with the American Bureau of Shipping. In November 1968 it gained authority to issue Panama Canal tonnage certificates, and in 1970 it added Suez Canal tonnage certificates and authority from Panama to carry out statutory surveys, followed, the society says, by Liberia, Greece and other flag states. Its register passed 1 million gross tons in November 1972.

Membership of the international association came in stages. KR became an associate member of the International Association of Classification Societies in September 1975 and a full member in May 1988, according to its timeline; its services page also gives 1988. In January 1990 it was listed in the Institute Classification Clause of the London underwriters, and in July 1998 it held the chairmanship of the IACS Council. Through the 1970s and 1980s it added work beyond hulls: certificates of fitness for ships carrying liquefied gas in bulk in 1979, approval of containers under the TIR and CCC conventions in 1982 and under UIC rules in 1985, and certificates for mobile offshore drilling units in 1984. The register passed 10 million gross tons in January 1988.

Surveys, certificates and digital tools.

Classification is the core of KR’s work: writing rules, reviewing drawings and surveying ships during construction and in service. Korean Wikipedia lists its main tasks as plan review and survey for the building, registration and inspection of ships; approval and inspection of shipbuilding materials, marine products and onshore equipment such as power plants; supervision of shipbuilding and of the making of cranes and other machinery; work under international conventions and on behalf of governments, including inspections for the Korean government under the Ship Safety Act; and certification for renewable energy and greenhouse-gas schemes. The society says it holds recognised-organisation status from many flag states, which allows it to carry out statutory surveys on their behalf.

Its services page groups the work under six headings: survey, certification, digital technology, energy and environmental services, naval services, and research and development. Under the digital heading KR says its ambition is to become “Digital Class KR,” developing big-data, cyber-security and remote-survey tools; under naval services it says it verifies technical documentation for naval vessel design. Its software line includes the KR-CON convention database, launched in June 2000, and the SeaTrust-HullScan program. The timeline also records KR Engineering, set up in February 1997, a Naval Business Center opened in January 2008, and regional headquarters for China and Europe established in May and July 2008.

The headquarters have moved twice. They moved to Daejeon in October 1993 and to Busan in September 2012, according to the timeline; Korean Wikipedia says a general meeting approved the Busan move in February 2005 and places the new building in Myeongji, in Busan’s Gangseo district. Korean Wikipedia also lists branches across the country, from Seoul and Incheon to Ulsan, Geoje and Pohang.

How classification societies present themselves.

A classification society’s output is mostly rules, surveys and certificates, and its identity tends to draw on marks of approval, dates and documents. Lloyd’s Register says its surveyors have stamped an LR mark into steel since 1884 and that its 2021 logo is a reading of that stamp in a colour it calls marine green; the American Bureau of Shipping’s eagle and anchor still sit on top of 65 Broadway in New York, its headquarters from 1977 to 1986, according to Wikipedia. Founding years — 1760, 1862 — appear prominently on both societies’ websites.

The websites themselves are working tools as much as shop windows. Lloyd’s Register lists its rules and regulations, an “LR Ships in Class” search, an office and port finder and an e-certificate verification portal; ABS offers a Rule Manager, the ABS Record database of classed vessels and certificates, and databases of type-approved products and service suppliers.

Much of the work now reaches beyond ships. Lloyd’s Register says it first inspected refrigerated cold stores in 1911 and later worked in nuclear power, oil and gas; ABS describes independent certification for marine and offshore products, materials, equipment and containers. Both societies have set up or spun off separate businesses for training, software, management systems and consulting.

They also publish heavily. Lloyd’s Register lists research reports, regulatory updates, podcasts and webinars; ABS lists regulatory news, advisories and an annual review. This guide sets out what can be checked about each society — when it was founded, how it is owned and how it presents itself — and marks clearly what rests on the society’s own word.

A blue circle and Cobalt Blue.

KR sets out its identity on a short CI page. Its logo, announced in June 2017 in the society’s 57th year together with a new vision, is a blue circle inspired by the sea, with the letters KR placed inside to stand, the society says, for a classification society’s role in bringing together the interests and needs of stakeholders across the maritime industry. The identity colour is named Cobalt Blue, which KR says expresses a love of the sea and of ships and a sense of challenge and movement. The page also specifies Korean typefaces for consistent use, with weights chosen to suit the purpose of the text, and offers the logo as a download.

The register keeps growing. KR’s timeline records 50 million gross tons in March 2012, 60 million in January 2013, 80 million in November 2022 and more than 90 million gross tons in December 2025. Its 60th anniversary fell in June 2020, and in September that year it opened an LNG simulation centre.

It also works with the country’s shipbuilders. In May 2026 MarineLink reported that KR had published numerical calculation guidelines for determining a ship’s attained EEDI, the IMO energy-efficiency design index, developed in joint research with HD Hyundai Heavy Industries and Samsung Heavy Industries. The guidelines set out a method based on computational fluid dynamics as an alternative to physical model tests in towing tanks, and include modelling requirements for air-lubrication and wind-assisted propulsion systems.

For a design guide, Korean Register shows how a class society can reduce itself to two letters in a circle and one named colour. Compare ClassNK, the Japanese society that adopted its short name in 1992, and HD Hyundai, the Ulsan shipbuilder. For this guide we use a deep cobalt, a sea grey and white with a sans, an unofficial interpretation; no product or logo is reproduced.
