The Front End Engineering Design (FEED) study moves the conceptual choice from idea to viable solution that is easy to construct and operate. The primary purpose of the FEED study is to provide a cost estimate, which enables the final investment decision. Moreover, it provides the basis for the EPC or detailed engineering tender and contract.

Our Front End Engineering Design study embraces the full project lifecycle

In the FEED study, Ramboll’s specialists take into account the entire lifecycle needs of an asset, enabling us to present robust solutions that create value from commissioning to decommissioning.

We aim for design solutions that are easy to fabricate, install, operate and maintain. Our FEED studies are therefore geared towards making the right operational and materials choices, reducing costs and risks, whilst keeping down-time to a minimum.

Deliverables in the FEED phase

Our cost estimates for FEED will be accompanied by a number of deliverables that substantiate the estimates and serve as a basis for procurement of items with long lead times. If required, the FEED study can also address environmental or regulatory aspects.

HSE and regulatory compliance

Our FEED studies also consider health, safety and environmental (HSE) aspects, and we offer risk evaluations and environmental screenings to safeguard people and the environment. Moreover, we identify legislative and environmental requirements and devise environmental programmes comprising all necessary steps for obtaining approvals and permits.

With a worldwide office network, Ramboll has intimate knowledge of national standards, regulatory frameworks, and authority requirements enabling us to act in the capacity of certified verification agent, technical authority and third party verification partner.

Our services within FEED cover:

  • Cost & weight estimation
  • Safety and control system philosophies
  • Equipment sizing and specifications for utilities
  • Material Take-Off lists (MTO’s) and specifications of long lead items
  • Installation procedures
  • Preparation of EPC tender material
  • Design verification


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.

3D model of the FPSO Petrojarl 1

Lifetime extension for FPSO Petrojarl 1

FPSO Teekay Petrojarl I was operating on the Glitne Field for Statoil, and was planned to operate for another five years there. In turn, the owner of the FPSO, Teekay Petrojarl Production, was evaluating to extend the lifetime of the FPSO with 15 years.

The world largest pipelay vessel will install the record breaking 36" Polarled pipeline

Polarled: Record-breaking subsea pipeline crosses the Arctic Circle

The Polarled pipeline project is part of the plans for developing fields further north in the Norwegian Sea.  

FEED and detailed design for Gudrun pipeline system

As part of the Sleipner SPORT development project, satellite platform Gudrun was tied-in to Sleipner, for oil and gas processing and export. Statoil awarded Ramboll the FEED and detailed engineering of the subsea pipeline system.

Cathodic protection of more than 600 wells

In 2010 Qatar Petroleum initiated a major life time extension programme in the Dukhan field 95 km west of the capital Doha in Qatar. Ramboll was awarded the Front End Engineering Design (FEED) study for the cathodic protection and off plot power supply for more than 600 oil, gas, and water wells.

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.
