Marseille, France – 20 January, 2026: Opsealog, a pioneer in operational and environmental performance solutions for maritime fleets, today announced a major evolution in its corporate structure following a strategic carve-out. The management team has joined forces with the Impact Ocean Capital fund (managed by GO Capital) and Sud Mer Invest (Banque Populaire Group) to acquire the entire share capital of the company.
A New Level of Autonomy to Accelerate Global Expansion
After ten years of continuous growth and the deployment of its solutions across more than 1,000 vessels worldwide, Opsealog is gaining full strategic independence. This transaction provides the company with renewed financial and operational agility to scale internationally and reinforces product innovation by leveraging AI and machine learning models. It also enables Opsealog to seize emerging opportunities driven by the decarbonization of the maritime industry, with the ambition of establishing itself as the leading global name in offshore and maritime operations management within five years.
Technological Expertise Validated by Concrete Results and Through Long-Term Client Partnerships
Leveraging advanced analysis of onboard operational data, Opsealog empowers members of the maritime industry to achieve both economic efficiency and measurable decarbonization. Its solutions deliver up to 30% reduction in fuel consumption per vessel, representing average annual savings of 210 tonnes of CO₂ per unit.
Over the last 10 years, Opsealog has helped prevent more than 200,000 tonnes of CO₂ emissions worldwide – a testament to the impact and scalability of its technology.
Beyond Fuel: A Comprehensive Operational Intelligence Platform for Maritime
While fuel efficiency remains a cornerstone of Opsealog’s value, the company is extending its supporting capabilities to clients across a much broader set of operational challenges, including contract performance and vessel invoicing; fleet utilization optimization; waste management performance monitoring; regulatory reporting and compliance; as well as ESG and decarbonization tracking at scale.
This integrated value proposition positions Opsealog as a holistic operational excellence partner, not only a fuel optimization tool, combining operational performance and environmental impact reduction.
Arnaud DIANOUX (pictured above), Founder & CEO of Opsealog: “After celebrating Opsealog’s 10th anniversary, we are proud to embark on this new chapter alongside GO Capital. This moment marks a renewed commitment to combining maritime expertise and digital innovation to improve operational efficiency and accelerate decarbonization worldwide.”
“This strategic transaction will allow us to scale our commercial development, enhance our solutions, and deliver even greater value to our clients – supporting the maritime industry’s transition toward more efficient and environmentally responsible operations.”
Jérôme GUERET (pictured above), Managing Director of GO Capital – Impact Océan Capital: “This transition marks a decisive milestone in Opsealog’s journey. We are convinced that this new structure, built through close collaboration with the management team, gives the company the agility and resources needed to capture significant market opportunities.
