Raymond International is a world leader in project management, engineering, construction, operations and maintenance with a global perspective.

For more than a quarter of a century, Raymond Saudi Arabia Ltd., has established a reputation on some of the larger civil and engineering projects in the Kingdom.

The impressive project list includes Ju'aymah LPG trestle and offshore terminal for Saudi Aramco; SWCC water transmission lines; the Royal Commission for Jubail and Yanbu corrosion works; Sceco-East turnkey works and many other private sector projects.

Raymond Saudi Arabia operates in four separate core sectors - integrated pipeline services, corrosion technology, marine construction, and industrial construction.

During the past year Raymond Saudi Arabia Limited has performed several innovative and unique projects, introducing new pipeline services technologies to Saudi Aramco and other organisations in the Kingdom.

Raymond's innovative and environmentally-aware ''no dig'' concept was applied to the Kingdom's first subsea pipeline rehabilitation project using a combination of cured-in-place lining and in situ cement mortar lining executed across Tarut Bay near Ras Tanura.

For this project, a corroded and redundant 24 inch steel raw water pipeline was given a new lease of life using Raymond Saudi Arabia's unique rehabilitation methods. In fact, Raymond applied its ''no dig'' concept for the marine line, creating big savings for the client in terms of time and costs.

The turnkey project involved the design and installation of prefabricated cofferdams in order to isolate and protect the sub-sea pipeline in three separate locations from the raging tidal currents and 20 ft deep water of Tarut Bay.

Specialist marine equipment, barges and experienced diving teams were needed for accurate placement of the cofferdams on the seabed resting on top of the 24 inch pipeline.

Once access into the dry pipeline was possible through the watertight cofferdams, the pipeline was CCTV inspected, cleaned and then lined with a 15mm thick epoxy resin liner to form a new pipe inside the old pipeline for the 600 metre long sub-sea section.

An additional 3,500 lineal metres of 24 inch pipeline were cleaned and cement-lined on trestle sections extending out over the water.

Several hundred kilometers to the south, Raymond Saudi Arabia and Saudi Aramco engineers were planning the rehabilitation of a 42 inch seawater transmission pipeline which had developed major leaks.

The pipeline delivers treated seawater critical to Saudi Aramco's oil producing capabilities and could only be taken out of service for a maximum 60 day duration.

Raymond mobilised three spreads of special lining equipment, a 200 man-staff and more than 50,000 bags of special cement, sand and micro-silica in order to rehabilitate 24,000 lineal metres of desert pipeline.

The pipe rehabilitation was completed eight days ahead of schedule.

According to a spokesman for Raymond, both pipeline rehabilitation projects were completed successfully due, in large part, to the cooperation extended by Saudi Aramco management and project staff.

It is estimated that the cost saving of rehabilitating the pipelines on these two projects realised cost savings of around $25 million in comparison to replacement.

Raymond, since its establishment in 1897, has always pioneered new technologies particularly specialist pipeline refurbishment services.

In fact, the company's in situ mortar lining technology - the Centriline Process - is almost a generic term for in situ lining and the world's construction industry standard for cleaning and lining water mains.

During last year, Raymond introduced its Rayweld automated pipeline welding service, a new proprietary system that provides more consistent weld strength and NDT quality when compared to normal pipe welding.

The process also allows welding of high strength steel and CRA materials, using less manpower and equipment, on a cost competitive basis.

Typically, the welding system is up to three times faster than normal out of position welding applications.

The new welding process has been used successfully on projects for Saudi Aramco and for the Saudi Electricity Company where the process is also used for boiler tube installation and replacement at power plants.

In association with Al Khaja PIH of Dubai, Raymond undertakes heat treatment and NDT services.

Raymond Saudi Arabia Limited is wholly-owned by Ahmed Hamad Al Gosaibi & Bros and has achieved a continuous track record of success in the Kingdom since incorporation in 1976.
