What Sulmara does

Sulmara (legal entity: Sulmara Subsea International Limited) is a Glasgow-based subsea technology company founded in 2019 that provides survey and inspection services to the offshore energy sector, including offshore wind, oil & gas, and marine construction. The company operates the Sulmara Discover platform, powered by its proprietary eBOSS engine, which the company describes as transforming complex seabed data into actionable intelligence. The platform supports three specialized service modules: UXO (unexploded ordnance clearance using wide-swath imaging with magnetic correlation to reduce false positives and identify non-ferrous threats), Cable & Pipeline (high-resolution imaging from landfall to deep water including as-trenched and depth-of-burial surveys), and Geohazards (ultra-high resolution 3D subsurface modeling with signal penetration in challenging seabed conditions such as sandy soils).

Sulmara generates revenue through professional services contracts delivered directly to enterprise clients in the offshore energy and construction sectors, with a stated $70 million in annual revenue and a headcount of 101-250 employees. Pricing is not publicly disclosed and engagements appear to be bespoke project contracts. The company is privately held, headquartered in Glasgow, United Kingdom, with claimed offices worldwide and a global geographic reach. The leadership team includes founder and CEO Kevin McBarron alongside a CCO, CSO, CFO, and CIO, signaling organizational scaling. The company's primary go-to-market is direct enterprise sales supported by LinkedIn for corporate visibility, and it has no publicly listed customers in the available material.

In November 2024, Sulmara completed a £15 million (~$18.9 million) growth capital round from BGF, described as a vote of confidence for continued expansion. In 2025, the company received a $1.6 million Unmanned Surface Vehicle from Ocean Power Technologies, extending its operational capabilities toward autonomous survey operations. The company has no disclosed AI/ML research output, patents, or named proprietary models in the available material, and its competitive positioning rests on proprietary imaging technology, domain specialization, and integrated platform delivery rather than artificial intelligence differentiation.

Core offering

Sulmara is a subsea technology company that delivers offshore survey and inspection services to the offshore energy sector, using its proprietary eBOSS-powered Sulmara Discover platform to transform complex seabed data into actionable intelligence. Its three primary service offerings are UXO (unexploded ordnance) clearance with smarter target discrimination, high-resolution cable and pipeline inspection from landfall to deep water, and geohazard assessment providing 3D subsurface models.

Product overview

Sulmara is a seabed intelligence company that offers a unified platform called Sulmara Discover (powered by eBOSS) along with three specialized service modules: UXO for unexploded ordnance detection and classification, Cable & Pipeline for offshore infrastructure inspection, and Geohazards for subsurface modeling and risk assessment. The platform transforms complex seabed data into actionable intelligence at speed.

Functional benefit

Products and services

• Sulmara Discover Seabed data transformation platform powered by eBOSS that converts complex seabed data into actionable intelligence at speed; serves as the underlying platform enabling Sulmara's UXO, Cable & Pipeline, and Geohazards service offerings for offshore energy, construction, and marine operations.
• UXO (Unexploded Ordnance) Clearance Service for smarter target discrimination enabling safer, faster seabed clearance using wide-swath imaging with magnetic correlation; reduces false positives and identification costs; classifies pUXO and determines target depth; identifies non-ferrous threats; manages no-finds. Targeted at offshore energy and construction firms requiring UXO clearance ahead of offshore wind, oil & gas, and marine construction projects.
• Cable & Pipeline Survey High-resolution imaging service from landfall to deep water for offshore cable and pipeline inspection. Includes rapid as-trenched and depth-of-burial surveys, detection of out-of-straightness and out-of-service assets, and inspection of asset crossings and drill centres, delivering reliable high-resolution results in challenging seabed conditions. Targeted at owners and operators of subsea cables, pipelines, and infrastructure.
• Geohazards Assessment Geohazard assessment service that provides 3D subsurface models to reduce the risk of unforeseen ground conditions. Detects buried boulders, shallow gas, and seeps with ultra-high resolution imaging and unparalleled signal penetration even in sandy soils. Includes advanced palaeo-landform mapping, archaeological screening, and integration with CBRA and BAS work streams, enabling advanced planning with real-time subsurface insight for offshore project developers.
