Instrumentation, control and safety systems

Our dedicated Electrical, Instrumentation & Telecom teams provide designs and engineering for all types of control and safety systems, including SCADA/DCS and safeguard/ESD/F&G/HIPPS systems. We also offer expertise in field instrumentation for communication such as metering systems.

We ensure that the client's safety philosophy is fully integrated into the design of elements such as ESD systems, emergency power systems, fire and gas detection, as well as passive and active fire protection.

Power generation and distribution

Ramboll possesses expert knowledge in electrical power calculations as well as designing and specifying power generation and distribution systems.

We design power and control systems in hazardous areas to minimise the risk of ignition. Our main expertise is based on IEC standards and ATEX requirements. Furthermore, we are experienced in F&G mapping to enable proper shutdown.

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

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.

EPCM assistance to Equatorial Guinea Development

The Alba Field is one of the largest producers in the Gulf of Guinea. As engineering consultant, Ramboll paid a significant contribution to the development of the oil and gas field from 1997-2003.

Fire and safety

Fire and gas detection system for the Tyra platform complexes

For all modification projects reducing shutdown time to an absolute minimum without compromising safety is vital.

Tanker ship at sea

Gryphon FPSO - air compression upgrade project on an EPCM contract

The Maersk owned Gryphon Alpha FPSO processes oil and gas for the Gryphon, South Gryphon, Tullich and Maclure fields in the British North Sea. The oil is exported by tanker. Gas is exported via a pipeline to Beryl Alpha, where it is transported to shore via the SAGE system. For this project Ramboll performed detailed design including procurement and fabrication of 3 new air compressor skids.

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.

Halul Island, Quatar

Detailed design of crude oil import and export facilities at Halul Island

80 kilometres off the coast of Qatar, Halul Island is the base for 11 large crude oil storage tanks and pumping facilities, as well as power generation and water desalination plants. Ramboll was chosen to be part of plans to expand this complex, by carrying out a detailed design of the crude oil import and export terminal.
