Royal HaskoningDHV has developed core expertise in engineering the maritime features unique to Liquefied Natural Gas (LNG) terminals, building on its extensive knowledge of maritime engineering for other types of terminals, including health and safety requirements.

LNG terminal design, maritime consultants

LNG terminals often comprise special tanks, ships and even building structures, as well as incorporating port infrastructures and pipelines. Royal HaskoningDHV has extensive experience of all marine works associated with the design of such purpose-built ports, which are used exclusively to export and import LNG.

We have been responsible for assisting in the planning, design or construction supervision of more than 50 LNG terminals since 1999.

We understand that LNG terminal projects are subject to many unique differences from projects in other sectors. These include:

  • The even greater importance of minimising delays, due to the large investments involved;
  • The important role that standards and Quality Assurance / Quality Control play in the light of classification society requirements;
  • The influence of capital cost of different elements (maritime civil engineering, process, landside infrastructure);
  • The fundamental necessity of Health, Safety, Security & Environment issues in all aspects and all phases of the project;
  • Accountability and traceability through Project Administration and Document Control.

Our expertise includes:

  • Site location studies;
  • Terminal development plans and feasibility studies;
  • Terminal traffic forecasting and logistics analysis;
  • Terminal and jetty design;
  • Outline design of product handling systems;
  • Shipping and Navigation studies;
  • Combined LPG-LNG jetties planning;
  • Environmental and Social Impact Assessment;
  • Foundation engineering;


  • Mechanical & Electrical services;
  • Fire fighting design;
  • Quay wall design;
  • Mooring design;
  • Breakwaters and coastal structures design;
  • Cooling/Heating Water Intakes and Outfalls Design;
  • Dredging design;
  • Engineering [Pre-FEED and FEED Studies]
  • LNG tank Design
  • Technical Appraisal/Review

LNG partnership
Together with other parties joined in the Society for Gas as a Marine Fuel (SGMF), Royal HaskoningDHV contributes to improving air quality by promoting LNG as vessel fuel, which contributes significantly to reducing various emissions into the atmosphere. Conversion to LNG also helps to reduce greenhouse gas emissions compared to fuel oil. LNG is the cleanest non-renewable energy resource, and will likely play a large role in the energy transition.
