Company Founded

Shearwater Marine Services was founded in 1992 by Alastair Baird and Tom Brannan. In its early years, Shearwater Marine Services worked primarily on small civil engineering contracts in Argyll & Bute, as well as local fish farm maintenance contracts. These projects allowed the company to establish a foothold in the industry and gain valuable experience, which helped to pave the way for its expansion into larger and more complex projects. Over time, Shearwater's reputation for quality and reliability grew, leading to more significant contracts and partnerships with clients across a range of sectors.

Shearwater Marine Services has been providing high-quality services to the defence infrastructure inspection program, through which the company has been contracted to support the management and maintenance of HMNB Clyde and RNAD Coulport's Waterfront with specialist subsea inspection engineers since 1994.

Shearwater has demonstrated their expertise in supporting the Royal Navy Submarine Maintenance Program since March 1997, with their first contract on the RN Submarine Service.
