Allam Marine

What Allam Marine does

Allam Marine (legally Allam Power Ltd) is a privately held British manufacturer and distributor of diesel power generation equipment, established circa 1934 and headquartered in Melton, on the outskirts of Kingston upon Hull. Its commercial operation spans two distinct revenue models executed from a single English manufacturing campus: the design, assembly and sale of complete Tempest-branded industrial generating sets from 5 kVA to 3,000 kVA, configured around engines from Perkins, Cummins and Volvo paired with Mecc Alte and Leroy Somer alternators; and the wholesale supply of completely knocked down (CKD) loose engines and matched alternators to third-party generator set assemblers worldwide, a category the company pioneered in 1989 and in which it holds exclusive global approved-supplier status with all three OEMs. Supporting revenue streams include Gentronics-branded control panels (designed and built in-house), genuine spare parts and service kits for the underlying engine and alternator brands, and custom soundproof canopies; a new eStorm hybrid product line, integrating diesel generation with renewable energy and battery storage via Victron, Leoch and Mecc Alte components, is scheduled for formal launch at Middle East Energy 2026.

The company serves end customers across manufacturing, data centres, healthcare, telecommunications, government, mobile and rental applications, as well as a B2B channel of generator set assemblers purchasing CKD kits. Sales are conducted through direct enterprise engagement and channel supply to OEM assemblers, with no public pricing and quote-based transaction terms. Manufacturing capacity is organised around ten specialised production lines, supported by 3.0 MW of calibrated load banks (enabling ISO 8528-compliant testing of every set before release) and a stocking position of more than 9,000 engines and alternators for immediate delivery, described as one of the largest in Europe. Quality and access barriers are reinforced by ISO 9001 (ISOQAR UKAS) and CE UKCA certifications, with the corporate track record recognised by two Queen's Awards for Enterprise.

Operationally, Allam Marine employs between 11 and 50 staff, operates from a single UK site, and distributes globally with export shipping capable of handling multiple 40 ft containers simultaneously. Ownership is private and undisclosed, with no institutional investors, no disclosed funding history and no public listing; CEO David Oates is the only named executive. Legal entity, awards posture, OEM partnerships and factory location have remained stable since the 2008/2012 Melton expansion, with the eStorm hybrid programme representing the most material product and geographic expansion initiative in over a decade.

Direct peers

• Aksa Power Generation: Aksa is one of the largest independent global manufacturers of diesel generator sets, producing a similar kVA range and serving data centre, telecom, and industrial markets. It is a direct competitor particularly in Middle East and emerging markets where Allam is expanding.
• Perkins Engines: Perkins is both Allam's largest engine supplier (sole global CKD partner) and a competitive gen-set engine provider used by rival assemblers. The strategic interdependence makes Perkins the most material peer — any change in Perkins' CKD or distribution policy directly impacts Allam's value proposition.
• FG Wilson (Caterpillar): FG Wilson, owned by Caterpillar, manufactures diesel and gas generator sets across a similar 5-3000+ kVA power band and serves the same mission-critical, industrial, and commercial backup-power customers as Allam Marine. It is one of the most direct competitors in EMEA and global markets.
• KOHLER Power Systems: KOHLER (including KOHLER-SDMO) manufactures industrial diesel generator sets, switchgear, and control systems serving data centres, healthcare, and telecom — overlapping directly with Allam's Tempest and Gentronics portfolio. The combined entity is a global incumbent across the same customer verticals.
• Volvo Penta: Volvo Penta supplies diesel engines for power generation and is one of Allam's three exclusive global CKD partners, while also selling complete generator sets through its own channels. The dual supplier/competitor dynamic closely mirrors the Perkins relationship.
• Himoinsa: Himoinsa designs and manufactures diesel, gas, and hybrid generator sets with integrated control panels across industrial, data centre, and rental segments — directly comparable to Allam's Tempest and emerging eStorm hybrid product lines.
• Generac Industrial Power: Generac Industrial Power manufactures diesel and gaseous generator sets for commercial and industrial applications, including data centres and healthcare. The product range, customer verticals, and global distribution model closely parallel Allam's Tempest offering.
• MTU Rolls-Royce Power Systems: MTU (a Rolls-Royce Power Systems brand) manufactures large diesel and gas generator sets, plus power management and control systems, targeting data centres, hospitals, and industrial customers — overlapping with Allam's higher-kVA Tempest range (up to 3000 kVA) and Gentronics control offering.
• Cummins: Cummins is one of the world's largest manufacturers of diesel generator sets and engines for power generation — directly competing with Allam's Tempest product line across commercial, industrial, and data centre segments. Allam is simultaneously a Cummins CKD partner, making Cummins both a supplier and the most direct competitive threat.
• Teksan Generator: Teksan is a global manufacturer of diesel generator sets with in-house control panel production and a CKD-style supply model, serving similar industrial, data centre, and telecom segments. Comparable size, scope, and value-chain positioning to Allam Marine.
