Calash is pleased to announce that it provided commercial due diligence and independent market intelligence to Foresight Group on its investment into J+S Subsea, a specialist subsea engineering business focused on the provision, repair, refurbishment, and lifecycle support of subsea control systems.
What Does J+S Subsea Do?
Headquartered in Dyce, Aberdeen, J+S Subsea delivers proactive and cost-effective engineering solutions across the Subsea Production Control (SPC) market, including:

Since completing a management buyout in 2020, the business has delivered significant growth, with revenues more than doubling and recognition as one of Scotland’s fastest growing companies in 2024.
Calash’s Role: Deep Dive Commercial Due Diligence
Calash conducted comprehensive commercial due diligence (CDD) on behalf of Foresight Group, providing assessment of J+S Subsea’s positioning within the subsea controls and offshore energy services markets.
The scope of work included:
- Independent market review of subsea control systems, brownfield lifecycle support, and offshore asset integrity services
- Market mapping across operators, OEMs, engineering houses, and supply chain stakeholders
- Competitive positioning analysis versus niche engineering service providers and OEM aligned control system companies
- Assessment of J+S’s growth strategy, commercial model, and revenue scalability
- Review of the business plan, investment thesis, and potential exit pathways
- Customer referencing to validate service delivery, responsiveness, and technical capability
This analysis supports Foresight as it positions J+S Subsea for continued expansion, particularly as energy transition projects drive demand for refurbishment, re-engineering, and enhanced reliability of subsea control assets.
