Process engineering

Converting crude oil and gasses into actual sales commodities requires separation and processing by efficient, reliable and safe processing facilities that live up to the desired OPEX. Process engineering therefore becomes the focal point for other engineering activities in all exploration and production activities.

Process safety

Ensuring safe operation is a key element in Ramboll’s process engineering design. Every project is developed in close coordination with our technical safety team and is subject to a safety analysis check - ensuring that all client standards and relevant codes are met. In focusing on process safety, we have developed our own PSV calculation tool that enables precise blowdown and release calculations.

Our process engineering services cover:

  • Production, treatment, compression, transmission and distribution of hydrocarbons
  • Process simulation and flow assurance using PVTSim, Aspen Hysys, Pipeline Studio and OLGA
  • Equipment sizing and evaluation of equipment configuration
  • Process safety; HAZIDs and HAZOPs
  • Debottlenecking; modifications & maintenance
  • Zero flare systems and 'green projects'
  • Design reviews and design verification

System design and flow assurance

Flow modelling and simulation provides insights into the physics describing flow behaviour from reservoir pore to process facility.

Our early-phase studies are based on accurate process simulations and a strong focus on flow assurance and loss prevention strategies, including material selection. We apply our vast knowledge of process engineering, oil and gas facilities, pipeline systems and fluid thermodynamics to deliver optimised system design.


Production facilities and terminals are continuously undergoing changes and are subject to lifetime extensions. Debottlenecking is therefore an important means of quantitative process optimisation.

Ramboll's process engineering experts have debottlenecking experience from a range of brownfield projects and can design solutions that increase production with minimal retrofits.

Sustainable process engineering solutions

In response to stringent environmental regulations and the consistent focus on sustainability, Ramboll has specialised in ‘green’ projects such as zero flare systems and emissions studies.

We apply our process engineering services for Offshore platforms, Floating production, Pipelines & subsea, Onshore production & refining, Terminals, storage and pipelines and Gas & LNG.


Cutting carbon footprints - flare gas recovery on South Arne

Hydrocarbon emissions from platforms and refineries are a source of atmospheric pollution, and there is a strong drive in the industry to find environment-friendly solutions. Ramboll Oil & Gas has considerable experience in this field, and recently we completed the design of a flare gas recovery system for the North Sea platform, South Arne operated by Hess Denmark.

Tyra East Rationalisation Project

The Tyra Field is the largest gas field in the Danish North Sea sector – it is operated by Maersk Oil, and has been producing since 1984. Ramboll has been part of the Tyra East Rationalisation Project; just one phase in a series of Optimisation Projects in the field.

Polvo Field Development - Engineering services

We carried out a significant engineering project for the Polvo Field Development off the coast of Brazil.

Visualisation of Nexus FPSO

Pre-engineering and detailed design on Nexus FPSO topsides

In 2006 Ramboll Oil & Gas commenced our biggest project to date when we initiated the pre-engineering work on the Nexus project for APL NEXUS and Samsung. Nexus is a generic FPSO with a free and fully weather-vaning turret mooring that can accommodate up to 6 risers.

Flare with smoke

Smokeless flare, Fahahil Stripping Plant

Ramboll was given the task of remodelling and enlarging an existing old flare system at the Dukhan oil field on the west coast of Qatar.  In addition, we were to find a method for reclaiming some of the gas that would otherwise be burnt in the tower. At last, we were to implement improved combustion technology to obtain what is known as a “smokeless flare”- which means a flame without smoke.

Norsea Gas Terminal in Emden, Germany

The Gassco Emden Project - Extensive revamp of vital onshore gas receiving terminal

After more than 30 years of operation, the Norsea Gas Terminal in Emden, Germany, needed to be refurbished to maintain safe and reliable gas transportation. The major scope of work included new receiving-, gas heating-, utilities- and process facilities. Ramboll carried out the FEED study proposing the technical solution.
