Mitsui Engineering & Shipbuilding

Mitsui E&S was established in 1917 as the Shipbuilding Division of Mitsui & Co. with the first shipyard at Tamano.{{cite web|url=http://www.mes.co.jp/english/company/history.html|title=History│About Mitsui E&S Group│Mitsui E&S Group|website=mes.co.jp|access-date=19 April 2018}} It built the first Japan-built diesel-propelled merchant ship, Akagisan Maru (赤城山丸) in 1924. With its success, it began manufacturing diesel engines under a license agreement with Burmeister & Wain in Denmark.{{Cite news |last= |first= |date=2013-04-17 |title=Mitsui Engineering demonstrates ME-GI engine |url=https://www.marinelog.com/news/mitsui-engineering-demonstrates-me-gi-engine/ |access-date=2023-01-20 |website=Marine Log |language=en-US}}

In 1937, the shipyards became a separate entity within the Mitsui zaibatsu, Tama Shipyard. The company changed its name to Mitsui Shipbuilding & Engineering Co., Ltd. in 1942. In 1948, Mitsui E&S built the first Japan-built ship to be exported after the loss of the Second World War, S.S.Knurr (a Norwegian whaling ship). In 1951, it started its chemical plants business by building a nylon production plant for Toray Industries.{{Cite web |title=沿革│企業情報│三井E&Sグループ |url=https://www.mes.co.jp/company/history.html |access-date=2024-02-09 |website=www.mes.co.jp |language=ja}}

In 1961, it built 'the world's first automated ship' Kinkasan maru (金華山丸）for MOL. This ship was the first of its scale to control the entire engine room from the bridge, and other major parts of the ship were also automatically or remotely controlled from the bridge.{{Cite web |title=Engine Control Console Installed on Bridge of Kinkasan Maru Certified as 1st 'Ship Heritage' - A Pioneer of Remote Operation and Automatic Control of the Main Engine - {{!}} Mitsui O.S.K.

In 1967, as the container ship age dawned, it built its first gantry cranes for container ships. In 1975, it built the Berge Emperor, which was the longest ship ever built at that time, measuring 391.83m, for Bergesen d.y. in Norway.

Mitsui E&S acquired Burmeister & Wain's engineering and construction business in 1990, and through this acquisition, it also acquired Burmeister's boiler business in 2017, which primarily caters to small and medium biomass power plants.{{Cite web |title=An industry-historical circle was completed this weekend |url=https://stateofgreen.com/en/news/burmeister-wains-two-old-energy-divisions-re-unite-under-one-roof-at-the-leading-power-plant-specialist-and-energy-company-bwsc/ |access-date=2023-01-20 |website=State of Green |language=en-US}}

Mitsui E&S split its naval and merchant shipbuilding businesses in 2021, selling the former (including the Tamano Shipyard) to Mitsubishi Heavy Industries and selling a 49% stake in the latter to Tsuneishi Shipbuilding.{{Cite web |last=Mandra |first=Jasmina Ovcina |date=2021-03-30 |title=Mitsui E&S, Tsuineishi push forward with consolidation efforts |url=https://www.offshore-energy.biz/mitsui-es-tsuineishi-push-forward-with-consolidation-efforts/ |access-date=2023-01-20 |website=Offshore Energy |language=en-US}} Tsuneishi took over a majority stake of the merchant shipbuilding business in 2022 as Mitsui E&S refocused its strategy on marine engines, port cranes, and other machinery.{{Cite web |date=2022-09-27 |title=三井E&S、IHIから大型船舶エンジン事業買収の契約締結 |url=https://www.nikkei.com/nkd/company/article/?ng=DGXZQOUC272PA0X20C22A9000000&scode=7003 |access-date=2023-01-20 |website=日本経済新聞 |language=ja}}

In 2022, Mitsui E&S agreed to purchase IHI's marine engine business, and announced that it was in the process of developing ammonia-fueled marine engine technologies as a means of reducing {{CO2}} emissions.{{Cite web |date=2022-12-02 |title=三井E&SHD 高橋社長 |url=https://www.nikkei.com/nkd/company/article/?ng=DGKKZO66470590R01C22A2TB1000&scode=7003 |access-date=2023-01-20 |website=日本経済新聞 |language=ja}}

PACECO CORP. is a wholly-owned subsidiary of Mitsui E&S headquartered in Hayward, California. It built the first dedicated ship-to-shore container crane in the world in 1958. On 22 February 2024, the White House announced that as part of its 20-billion-dollar scheme to upgrade and secure the country's port infrastructure, Mitsui E&S and PACECO are planning to resume manufacturing cranes in the US.{{Cite web |last=House |first=The White |date=2024-02-21 |title=FACT SHEET: Biden-Harris Administration Announces Initiative to Bolster Cybersecurity of U.S. Ports |url=https://bidenwhitehouse.archives.gov/briefing-room/statements-releases/2024/02/21/fact-sheet-biden-harris-administration-announces-initiative-to-bolster-cybersecurity-of-u-s-ports/ |access-date=2024-02-22 |website=The White House |language=en-US}}{{Cite web |title=Biden ⁠Harris Administration Announces Initiative to Bolster Cybersecurity of U.S. Ports – PACECO CORP. |url=https://pacecocorp.com/biden-%e2%81%a0harris-administration-announces-initiative-to-bolster-cybersecurity-of-u-s-ports/ |access-date=2024-02-22 |language=en-US}}
