What Rotary does

Rotary Engineering Pte Ltd is a Singapore-headquartered engineering, procurement, and construction (EPC) group founded in 1972, specializing in tankage, mechanical construction, electrical and instrumentation (E&I), fabrication, and integrated maintenance for the oil and gas, petroleum, petrochemical, chemical, and pharmaceutical industries. The company operates six fabrication workshops spanning more than 30 hectares across Singapore, Indonesia, Thailand, Saudi Arabia, and the UAE, with annual capacity of 1.2 million+ dB of piping, 9,000+ tonnes of structural steel, and 42,000+ tonnes of tankage work, supported by heavy capital equipment including CNC cutters, 70mm plate rolling machines, and 50m-span gantry cranes. Its services span conceptual engineering through commissioning, including specialized cryogenic and LNG storage tanks (e.g., 185,000 cbm full-containment LNG tanks at -165°C, the world's largest bullet tank at 1,293 tonnes), spherical pressure vessels, process plant piping, and shutdown/turnaround maintenance.

Rotary employs more than 6,000-7,000 multi-national staff across more than 12 countries, with 200+ in-house engineers and 600+ multi-skilled craftsmen enabling multi-discipline self-perform execution. The company is privately held and operates as a group of wholly-owned subsidiaries (Rotary IMC Pte Ltd, Rotary Tank Company, Rotary Mechanical & Construction, Rotary REI, Rotary-Thai Construction, PT Rotary Engineering Indonesia, Rotary Malaysia, Sinmec India, Supermec Middle East FZE, Rotary Engineering Duqm LLC) and joint ventures (Brunei Rotary Engineering with the Brunei Government; Petrol Steel JV for Saudi Arabia work). Revenue is generated almost entirely through project-based EPC contracts (large multi-year tank terminals, LNG facilities, refineries) and long-term integrated maintenance service contracts on Jurong Island and other petrochemical hubs; pricing is set through competitive tendering, with single contract values ranging from tens of millions to over S$200M (e.g., S$140M Jurong Port Tank Terminals, S$200M EPC in 2013, ~S$300M group wins in 2018).

Rotary's customer base consists predominantly of international oil majors and national oil companies — including Saudi Aramco, SATORP, Shell, ExxonMobil, Chevron, Total, SABIC, Vopak, Neste, Evonik, and TA'ZIZ (ADNOC/ADQ) — reflecting a B2B enterprise go-to-market executed through direct sales, tendering, and senior relationship management. The group maintains ISO 9001/14001/45001 certifications, consecutive RoSPA Gold and Gold Medal safety awards (2011-2020), Singapore WSH Awards, and recognition as a Top 30 EPC Contractor in the Middle East. Recent strategic activity has been weighted toward Middle East and Southeast Asia expansion, most notably the November 2024 TA'ZIZ Chemicals Terminal EPC award in Abu Dhabi and the January 2025 Brunei Government joint venture.
