13 May 2026: Global consultancy group ABL Group has signed an agreement to acquire 100% of the shares in Southeast Asia‑based consultancy SynergenOG, adding specialist capability in process safety and technical risk management and enhancing the group’s end‑to‑end technical offering to the energy industries.
Upon completion of the acquisition, SynergenOG will be integrated with the group’s design and engineering consultancy, Longitude. This integration will strengthen Longitude’s engineering offering across all business lines, creating a technical centre of excellence in process safety and risk management focused on driving safety, cost efficiencies and performance from concept design through to operations and late life.
“SynergenOG is an excellent addition to ABL Group and Longitude. SynergenOG and Longitude have a track record of successful collaboration, signalling a clear market appetite for integrated risk and engineering solutions, and a proven capacity to generate results together for our clients. With this acquisition, we bring SynergenOG’s expert safety and risk engineering in‑house. The deal also strengthens our Asia Pacific engineering footprint, while giving SynergenOG a larger platform to scale its services for the benefit of a wider range of energy markets,” says Hege Norheim, CEO of ABL Group.
About Longitude
Longitude is the design and engineering arm of global consultancy group ABL Group, with a heritage spanning more than 35 years supporting global energy and marine markets.
Its multidisciplinary team of more than 220 project managers, engineers and designers is based across 14 countries in Asia‑Pacific, Europe, Africa and the Americas. Longitude specialises in the delivery of end‑to‑end engineering and design projects across facilities and subsea, marine operations, ship design and offshore wind.
As part of ABL Group, Longitude brings together multidisciplinary engineering and design expertise with deep operational experience from across the group’s marine and energy businesses. Like SynergenOG, this enables Longitude to deliver engineering and design solutions rooted in the operational realities of its clients’ assets and projects.
“This is a synergy between two companies that already work well together, share similar goals and are focused on delivering client value. For Longitude, we bring niche process safety expertise that strengthens its market and client offering. For SynergenOG, the group provides a larger, multi‑disciplinary platform from which to grow globally,” continues Puvan Balasubramaniam.
Strategic rationale
The acquisition adds new services in process safety and technical risk engineering, enhancing Longitude’s and ABL Group’s overall technical offering to energy projects. SynergenOG’s services—including the design and delivery of HAZIDs and HAZOPs—are highly complementary to the group’s areas of expertise, spanning marine warranty survey, marine and subsea operations, and offshore wind development.
For Longitude, the integration of SynergenOG strengthens its facilities and subsea engineering offering, building on a growing track record in asset integrity management, and enables a fully integrated risk and engineering offering to clients at any stage of an energy asset’s design and operational lifecycle.
“Everything we do for our clients is geared towards reducing risk and driving efficiencies. With SynergenOG, we can deliver an expert safety and risk engineering capability that elevates our offering to support clients at every stage of an asset’s lifecycle,” comments Jake Anderson, CEO of Longitude.
The transaction also increases Longitude’s presence in the Asia Pacific region, including through a new in‑country presence in Brunei. This footprint provides Longitude with a strategic gateway to Borneo.
For SynergenOG, the acquisition provides a broader geographical and technical platform to scale its services. For colleagues, it creates increased opportunities for professional development, while existing clients gain access to a wider pool of more than 200 design and engineering professionals across energy, marine and engineering disciplines.
