Company history

Modec did not open a market; it was handed one. In June 1987 the original Mitsui Ocean Development — set up in December 1968 by Mitsui Engineering & Shipbuilding and Mitsui & Co. to design and build offshore structures — established a small Tokyo subsidiary called Modec Technical Services to do ground-penetrating radar surveys and consulting. Within eighteen months that subsidiary was the whole business.

The parent had ridden the offshore drilling boom on its own jack-up rigs to become Japan’s largest offshore contractor, with sales of $249.4M (¥55bn) in 1981. The oil price collapse from 1986 reversed it: the year to December 1987 produced a loss of $28.4M (¥4bn) on a balance sheet already thin from years of prioritising overseas investment and R&D. Suzuki Nanao took the presidency in November 1987 and pushed through voluntary retirement and board cuts, but by 1988 the company faced negative net worth. In December 1988 it was dissolved, its offshore business transferred to the subsidiary — which renamed itself Modec — and its shares split evenly between Mitsui Engineering & Shipbuilding and Mitsui & Co.

That origin fixed the shape of everything after it. Demand would be set by the exploration budgets of the oil majors, and ownership by whichever Mitsui company held the register: in March 1991 Mitsui & Co. sold its half to Mitsui Engineering & Shipbuilding, which became sole parent. The business itself narrowed onto FPSOs — floating production, storage and offloading vessels — designed, built, installed and then operated for the client. A US base in Texas followed in 1989, and ISO 9001 certification for FPSO design, construction, installation and operation in 1995.

The turn came in January 1999, when Modec formed MODEC INTERNATIONAL LLC in Texas with America’s FMC Corporation (later TechnipFMC) to serve the Americas and West Africa. From that base the company built its network field by field rather than region by region: Singapore in 2002 for Vietnam’s Ruby field, Brazil in 2002 for Bijupira-Salema, Côte d’Ivoire in 2004 for Baobab, Angola in 2008 for BP’s Plutão, Saturno, Vênus and Marte. Each subsidiary existed because a specific FPSO had to be operated there.

What made the model work was how little of it Modec owned. It had licensed mooring technology from outside since 1989, held no mooring patents, and ran no yard of its own — a president of the period, Miyazaki Toshiro, called it “a fabless company with no yards.” In the year to December 2006 the parent company employed ninety people while consolidated revenue reached $852.3M (¥99bn). That December, Modec bought the mooring specialist SOFEC outright from FMC Technologies for $54.4 million, pulling the one technology it could not design around inside the group.

The corporate identity caught up last. In January 2003 the company changed its name back from Modec to Mitsui Ocean Development & Engineering, restoring the name its dissolved parent had carried, and listed on the Tokyo Stock Exchange Second Section that July, moving to the First Section in June 2004. Growth then ran with the oil price: consolidated revenue rose from $852.3M (¥99bn) in FY2006 to $3.6B (¥379bn) in FY2014. The engine was Brazil — a first order from Petrobras in 2005, then six units as pre-salt development expanded, one Tupi vessel alone worth an estimated ¥100 billion. Modec had become valuable enough to move its parent’s affairs: the collapse of the 2013 merger talks between Mitsui Engineering & Shipbuilding and Kawasaki Heavy Industries is widely attributed to Kawasaki’s interest in acquiring it.

When oil fell from above $100 a barrel to under $40 in late 2014, the majors postponed and shrank new developments, and the FPSO order book thinned across the industry. The immediate figures held up — FY2015 revenue of $2.4B (¥296bn), FY2016 revenue of $2.1B (¥230bn) with a net profit of $192.9M (¥21bn) — but the pipeline behind them did not.

From FY2017 Modec reported under IFRS, and the change mattered more than an accounting note usually does. An FPSO earns over a long operating life what it spends during construction; under IFRS, a cost overrun in the build phase is recognised as a loss immediately rather than absorbed by the charter revenue that follows. Several late-2010s awards ran over budget, and the losses landed at once: FY2019 revenue of $3.1B (¥333bn) with an operating loss of $44M (¥5bn) and a net loss of $167M (¥18bn); an operating loss again in FY2020; and in FY2021 revenue of $3.9B (¥429bn) against a net loss of $459.1M (¥50bn). Three consecutive years in the red, under Kozai Yuji (president from 2018) and Kanamori Takeshi (from 2021), spent tightening risk control and cost estimation on new bids. The pandemic collapse in oil demand in 2020 compressed the order pipeline further.

The structural break, though, came from the parent, not the subsidiary. Mitsui E&S — successor to Mitsui Engineering & Shipbuilding — was carrying enormous losses on an Indonesian coal-fired power project and restructuring around them. In November 2021 it sold down its stake and Modec left the consolidation, ending thirty years of shipbuilding-group control and opening the register to newcomers from trading and shipping.

The seat Mitsui E&S vacated was filled from an adjacent industry. In June 2023 Mitsui O.S.K. Lines subscribed to a third-party allotment of $107.4M (¥15bn) for 14.86% of Modec, as part of an alliance covering offshore business beyond FPSOs. In August 2024 it bought a further 89,500 shares on the market to reach 15.00% and become sole largest shareholder, accounting for Modec as an equity-method affiliate. The logic was complementary rather than financial: a shipping company’s knowledge of marine operations set against Modec’s hull, mooring and metocean engineering, aimed at offshore energy in a decarbonising market.

Miyata Hirohiko, from Mitsui & Co., took the presidency in 2023, directly after the three loss-making years, and issued a 2024–2026 medium-term plan in February 2024. The recovery showed in the numbers: net profit of $220 million in FY2024 and $361 million in FY2025, already above the $300 million target set for 2026. Awards followed the pattern the company had used for twenty-five years — put a local subsidiary in place first, then win the work: MODEC GUYANA, established in 2022 for ExxonMobil’s Stabroek operations, preceded the Hammerhead EPCI contract of September 2025, and Brazil’s Gato do Mato came in March 2025.

The other movement is inward. Having built the business on borrowed capability, Modec has spent recent years buying it in: SHAPE (2021, digital solutions, with Mitsui & Co.), Offshore Frontier Solutions (2022, EPCI, with Toyo Engineering), an Indian topside engineering and procurement arm in 2024, and in November 2025 the announced merger of MODEC America with SOFEC. Whether an asset-light contractor can carry FPSO scale and an expansion into offshore wind and CCS at the same time is the test the current plan will settle.
