International Safety Products

What International Safety Products does

International Safety Products (ISP) is a UK-based manufacturer of inflatable lifejackets and marine survival equipment, founded in 1981 and headquartered in Bootle, Merseyside. The company operates as Europe's largest manufacturer of marine inflatable lifejackets and holds Design Authority status with the UK Ministry of Defence. Its product portfolio spans the Challenger commercial marine workwear range (Worksafe, Worksafe Pro, Flexi-Wing, Interlock, and emergency-service variants from 100N to 330N buoyancy), a dedicated military and emergency services line (Assault Troop, Special Forces, Multi Role, General Service, and Hazardous Duty lifejackets plus ISSAC surface abandonment suits and MKII Tactical Waistcoats), the SOLAS-approved Intrepid immersion suit line, and a distribution arrangement with Hansen Protection covering the Sea Eco, Sea Wind, Sea MOB, Sea Work, and Sea Nordic suits. ISP's core technology is the patented Wave Barrier Technology — an interlocking lobe bladder design that self-rights the wearer in under five seconds and creates an overlapping wave barrier preventing secondary drowning. Buoyancy levels, operating heads (Halkey Roberts, UML, Hammar), inflation mechanisms (manual, automatic, hydrostatic), and AIS MOB device compatibility are configurable across the range.

ISP operates an exclusively B2B, trade-only go-to-market model — it does not sell to the general public. Revenue is generated through four streams: (1) direct hardware sales of Challenger brand and own military products; (2) hardware sales of immersion suits under the Intrepid line and via Hansen Protection distribution; (3) system supply contracts for total safety product packages, particularly to the offshore oil industry; and (4) service and maintenance packages including authorised service stations and recurring training courses. Distribution combines direct enterprise field sales, a dedicated Head of Sales function, an international distributor network, and bespoke own-label manufacturing where major leisure marine brands are emblazoned on ISP-manufactured jackets. Pricing is not publicly disclosed and all transactions flow through B2B sales channels on multi-year contract cadences.

The company's primary customer segments are verticalised: military and emergency services (UK MoD sole supply of ISSAC suits across 20,000 active units, international naval forces, UK armed-response police), commercial marine (offshore oil, fishing vessels, merchant shipping, passenger ferry operators), and leisure marine (superyachts and own-label leisure brands). Since October 2018, ISP has operated as a subsidiary of Alliance Marine Group following the consolidation of the 3Si Group (Ocean Safety, Typhoon International, Revere, and ISP), under which management continuity has been maintained with Andrew Richards as MD of Alliance Marine UK Holdings.
