Liquified gas & transition fuels

Responding to energy transition and supply pressures

The global shift to net‑zero energy systems is reshaping fuel supply chains and coastal infrastructure. In the near and medium term, liquefied natural gas and other transition fuels continue to play a vital role in energy security. At the same time, investment in lower‑carbon fuels such as ammonia, hydrogen and synthetic fuels is accelerating. These changes bring heightened expectations around safety, environmental performance, resilience and regulatory assurance, alongside growing public scrutiny.

Managing the unique challenges of liquefied and transition fuels

Liquefied gas and transition fuel terminals present a diverse set of risks and uncertainties. Operators must make informed decisions about where to locate new facilities, how to manage safety zones, and how different fuels behave during release, dispersion or marine transfer. Unfamiliar properties - such as ammonia toxicity or novel hydrogen carriers - require robust evidence and specialist expertise. Clients must also plan for long‑term adaptability, including fuel switching, co‑handling, integration with green production and responsible decommissioning.

Applying world‑leading hydrodynamics and engineering expertise

We bring decades of experience in complex liquid and gas terminal design, expanded to address both conventional liquefied gases and emerging low‑carbon fuels. Our teams apply advanced numerical models, real‑time navigation simulation, physical hydraulic modelling and detailed metocean analysis to design safe terminals and optimise operations. We assess dispersion pathways in air and water, plume behaviour, environmental interactions and underwater noise. Our port operations simulation and forecasting systems provide reliable decision support from concept through operation, building confidence in both established and unfamiliar fuel systems.

Enabling resilient, transition‑ready assets

Our work supports safe deployment today and long‑term scalability tomorrow. We help organisations plan transition pathways, model future demand scenarios and design infrastructure that can adapt as technologies, standards and markets evolve. By evaluating options to improve efficiency, reduce emissions, repurpose existing terminals and strengthen climate resilience, we help protect communities, ecosystems and long‑term investment value while supporting a smoother transition to low‑carbon energy systems.
