Recent moves7 records

Expansion highlights5 records

Direct peers

• Babcock & Wilcox: US-based boiler and power generation equipment manufacturer, designing and fabricating utility and industrial boilers, pressure parts, and heat recovery systems. Directly comparable to IPSI's Boiler Pressure Parts and HRSG product lines serving the same global power plant customer base (B&W is also an IPSI customer).
• Doosan Enerbility: South Korean power and industrial equipment manufacturer with deep boiler, turbine, and pressure vessel capabilities targeting coal, combined cycle, and geothermal customers. Comparable in scale, technology scope, and international EPC customer base to IPSI's power generation and static equipment business.
• PT Barata Indonesia: Indonesian state-owned industrial equipment manufacturer producing turbines, boilers, castings, and forging for power, oil & gas, and mining. A direct regional competitor and comparable domestic alternative to IPSI for power plant and heavy industrial fabrication in Indonesia.
• PT Bukaka Teknik Utama: Indonesian heavy industrial fabricator producing steel structures, bridges, towers, and power generation equipment. Comparable in fabricating capability, Indonesian footprint, and customer overlap in power transmission and mining infrastructure.

Broad incumbents

• Saipem: Italian oil & gas and infrastructure EPC contractor with in-house fabrication capability for offshore platforms, refineries, and petrochemical plants. Comparable in O&G-focused fabrication and overlap with Pertamina and similar customers, though Saipem is dominated by offshore EPC rather than shop fabrication.
• Tata Projects: Indian EPC and industrial fabrication company executing power, refining, and metals projects across South Asia and the Middle East. Comparable in heavy fabrication capabilities and customer overlap with Indian/global EPCs, though operating as a broader EPC contractor rather than a pure fabrication specialist.
• IHI Corporation: Wholly-owned parent of IPSI and a Japanese heavy industrial conglomerate with global power, infrastructure, and aerospace operations. Provides the technology, quality supervision, and customer pipeline to IPSI; broader portfolio makes IHI a 'parent-as-peer' for evaluating technology, quality, and global positioning.
• Mitsubishi Heavy Industries: Japanese heavy industrial conglomerate with extensive power generation, boiler, and turbine manufacturing. IHI's domestic peer and competitor; comparable in ASME-grade boiler and pressure part manufacturing for global power and EPC customers, but at materially larger scale and product breadth.
• Larsen & Toubro (Heavy Engineering): Indian multinational fabricating pressure vessels, heat exchangers, reactor vessels, and complex process modules for global oil & gas, petrochemical, and power EPCs. Comparable in static equipment manufacturing, materials expertise, and international customer base, but part of a much larger diversified conglomerate.
• Hyundai Heavy Industries (HHI): South Korean heavy industrial conglomerate with shipbuilding, offshore, and plant EPC divisions producing pressure vessels, boilers, and structural steel. Comparable in heavy steel fabrication capability and overlap with Hyundai as an IPSI customer; substantially larger and more diversified across marine and offshore.
