What Stone Marine Services does
Stone Marine Services is an independent marine engineering, service, and repair specialist founded in 1999 and headquartered in Inverkeithing, Scotland. The company provides maintenance, repair, and overhaul services for main propulsion, controllable pitch propellers, steering gear, thrusters and azimuth propulsion, marine controls, dynamic positioning systems (including ICON DP), stern seals, deck machinery, and propellers. It serves ship owners, vessel management companies, naval fleets (including the Royal Navy), oil & gas operators, and luxury yacht clients through three strategically located service centres in the UK, South Africa, and Namibia, supported by mobile field service teams available 365 days a year worldwide. The company is a wholly owned subsidiary of Langham Industries, holds ISO 9001:2015 accreditation, is a member of IMCA, and also owns the heritage deck-machinery brand Thomas Reid & Sons.
The business operates a hybrid revenue model combining professional services (marine repair, remote technical guidance), hardware sales (OEM and alternative spare parts with consignment-stock options), and recurring subscription revenue through its Planned Service Agreement (PSA) programme, which offers structured maintenance contracts with predictable costs, spread payments, and guaranteed engineer availability. Its 25+ mechanical and electrical service engineers are trained to OEM standards, and it has built authorised service-partner relationships with major marine OEMs including SCHOTTEL, Damen Marine Components, Kawasaki Heavy Industries, Rolls-Royce/Thrustmaster of Texas, Wärtsilä, Nakashima Propeller, REINTJES, Data Hidrolik, Marine Jet Power, and Kwant Controls. Stone Marine also operates a 24/7 Remote Guidance Service providing shore-based diagnostics to vessel crews.
The company has actively expanded its partnership portfolio and leadership bench from 2019 onward, including the appointments of Group Managing Director Ryan McIntyre, Director DP & Automation Colin Allan (elevated to the board in March 2025), Finance Director Connie Minty, and African General Manager Morne Hugo. Recent strategic moves include the 2023 triple hire from Kongsberg Maritime to build out the controls and dynamic positioning function, the 2023 Marine Jet Power service-agency appointment across Africa, the 2020 expansion into West Africa via a Nigerdock partnership, and the earlier acquisition of Thomas Reid & Sons to extend into deck-machinery manufacturing.
