Our projects Khursaniyah Gas Plant NGL recovery and sweetening on a world scale A grassroots gas treatment facility built by Technip for Saudi Aramco Khursaniyah Jubail ia n Sea Saudi Arabia This large and challenging project was built on Technip's long experience in gas processing. Located about 80 km North of Jubail, Saudi Arabia, it was completed in 2010 by the Bechtel-Technip Joint Venture. A ra b Contracting Strategy: a key issue to meeting the project schedule Client: Saudi Aramco Contractor: JV Bechtel-Technip (BTJV) The plant is on stream since June 2010 The project was structured in two phases: FEED and Open Book Estimate (OBE) CLSTK (Converted Lump Sum Turnkey) contract awarded on the basis of the OBE together with mechanisms for adjustment during execution Such a structure accelerated project execution allowing an early start to detailed engineering and procurement in parallel with FEED and seamless rollover to execution. Khursaniyah and the wider picture World oil demand is growing. The 0.5 MMBPD Khursaniyah Programme is part of Saudi Aramco's commitment to be a reliable supplier of energy to the world. Within the Khursaniyah Programme, Saudi Aramco produces 300 MMSCFD of associated gas from the upstream production facility (KPF). This and associated gas from the other fields is fed to the Khursaniyah Gas Plant (KGP). Khursaniyah Gas Plant (KGP) KGP treats a nominal 1,000 MMSCFD of sour associated gas and exports 560 MMSCFD of sales gas, 300,000 BPD of NGL and 1,800 T/D of molten sulphur. The gas is sweetened and sweet gas is then treated to recover NGL and produce sales gas. Acid gas is sent to three Sulphur Recovery Units. Recovered liquid sulphur is then sent to storage and loading facilities. Sales gas and NGL are exported via pipeline. KGP also receives sour hydrocarbon condensate that is treated in the Sour Condensate Unit with a nominal capacity of 60,000 BPD.

Exceptional Project Management skills enabled the coordination of nearly 200 million direct manhours on construction over a 3-year period. Khursaniyah Gas Plant Contractors Joint Venture The FEED and CLSTK contracts were awarded to the Bechtel-Technip Joint Venture (BTJV), two major contractors in Oil & Gas. The JV set up a Directorate in the Rome office of Technip to provide a single interface with Saudi Aramco. Project organisation The project was managed by the Directorate with key roles shared between Bechtel and Technip. Engineering & Procurement execution was distributed between the two operating centres of Rome (Technip) and London (Bechtel). Each center organised its own project team with Project Manager, Engineering Manager, Process Manager, Discipline Leaders etc. Procurement was split between the two centres by commodity: London dealt with piping and instrumentation, while Rome managed steel structures, centrifugal compressors and electrical commodities. All equipment specific to a unit was procured by the operating centre that had developed the related design. The Directorate led these two project teams, keeping full control of Purchase Orders, Schedules, Estimates (OBE) and Business Management. Technip and Bechtel have previously worked together on similar major gas projects in Qatar and Abu Dhabi. Capitalising on this, the two companies harmonised project procedures, schedules and IT tools. The challenge The supply and construction markets were heavily loaded during the project due to the number of investments made at the same time. Considering the significant procurement quantities, the project committed to early production with a number of manufacturers to ensure on-time delivery. HSE Many nationalities worked on site. People from Egypt, the Philippines, Pakistan, Bangladesh and India were the largest communities among many others. In order to bridge cultural diversity and language barriers, intensive training programmes were organised, using a multilingual approach and pictorial aids. These included both general induction training as well as dedicated sessions for specific subjects (working at heights, confined space, etc.).

With so many nationalities present on site with diverse cultures, instilling a common HSE culture in all activities was a major challenge. A challenge that the site team met through consistent and effective communication of the standards required. The Joint Venture's HSE programme that was created specifically for the project was followed and implemented by the Construction subcontractor. By doing this the team succeeded in keeping incident rates very low with a Total Recordable Case Frequency no higher than 0.03 at any time. Environment The project had minimisation of harm to the environment as a permanent objective. It set up detailed disposal programmes, especially for construction waste. As an example, three temporary evaporation ponds were built for the disposal of all kinds of water without affecting the land. Chemicalcontaminated fluids were carefully disposed of by a specialised company. Saudisation Saudisation was encouraged by Saudi Aramco. BTJV employed almost all major suppliers of pressure vessels and steel structures in the country and had many Saudis employed on the site team.
