Project Summary:
The South Ghawar field consists of 3 main areas namely Uthmaniyah, Hawiyah, and Haradh. The Haradh area is on the southmost part of the field while Uthmaniyah lies on the north. In between the two areas lie the Hawiyah area. The facilities in the South Ghawar Producing Department are comprised of 14 Gas Oil Separation Plants (GOSP), each having wet crude handling (WCH) facilities and gas gathering (GG) facilities. Haradh GOSP-3 is currently designed for 300 MBCD at 30% water cut. It has been forecasted that there will be an increase in production rate within Haradh GOSP-3 up to 420 MBCD starting from 2026. it is therefore necessary to develop extra processing capacity to accommodate the increase in the production. The objective of this project (BI-10-16921) is to provide facilities required to deliver and process additional 120 MBCD of crude production from HARADH GOSP-3 area of the South Ghawar field. Oil production from HRDH GOSP-3 area is planned to be increased above the GOSP oil handling facility. The increase in production will be sustained for 14 years with a maximum oil rate of 420 MBCD.
Project Summary:
The HyNet Project has grown in scale with a number of new industrial emitters emerging from the NW Region. This led to a change in the definition of the ‘Flexible’ case from the Pre-FEED 3MTPA plateau to 4.5MTPA with expansion to 10MTPA. The LBA CCS T&S Project development strategy foresees a gas phase transportation of the CO2 streams in the early stage of operation with additional compression. In the later stage of operation, CO2 streams will be transported in liquid phase and further compression system will be required. The trigger point for the transition from gas to liquid phase flow will be one of the following:
Part of the LBA CCS T&S Project development strategy is to make use of existing assets wherever possible, including pipelines and offshore platforms. A range of compression / pressure boosting configurations have been considered to explore how to manage the transition from ‘free flow gas’ mode to the dense phase transport offshore. The following development
stages have been identified:
• Stage 4: Dense Phase Transportation (Offshore Only)

Review and process the pertinent information regarding:
OTK was commissioned to provide expertise in reviewing the FEED Contractor’s work and defining requirements for subsequent EPC tenders. OTK provided client with direct working knowledge of the UK Regulatory framework which was essential in engaging the UK Regulator and developing the necessary submission requirements. OTK continues to provide the client with dedicated support in the areas below.
OTK was approached to perform detailed design HAZOP. The purpose of HAZOP study was to systematically review the process and operation of the proposed modifications and replacement of equipment in the FCC and Catalytic Polymerisation units in order to identify the potential hazards and operability problems. OTK reviewed the adequacy of the protective measures and proposed solutions or identify areas for further study. Each modified / replaced equipment of the installation was given line-by-line or stage-by-stage examination by the HAZOP team. This was done by using a set of guidewords in combination with system parameters to give meaningful deviations from the design intent. The team concentrates on those deviations that could lead to potential hazards to safety, health or the environment. In addition, the team also searched for potential operating problems.
OTK undertook the HAZOP using a structured approach according to established
Amec HAZOP techniques. This involved identifying and assessing potential hazards associated with the proposed modifications by applying primary and secondary guidewords to associated modes of operation and ensuring that suitable risk reduction measures are in place to manage identified risks.
OTK was commissioned to undertake Detailed Design Study and investigate the extent of modifications required, constructability issues, structural impacts, SIMOPS issues and regulatory requirements associated with the proposed Subsea tie-back structure Field which necessitates modifications and additions to the existing equipment.
As part of its hazard management process, validation of the previous safety studies will be carry out by OTK technical safety team. The basis of the Detailed Design scope is the FEED report, assumptions and conclusions prepared and issued by another contractor. This has been expanded upon through the addition of Sstructure recommendations.
OTK Safety team will address the deluge system/requirement in the detailed design. This was deemed not required at the FEED stage of the design. The deluge system shall provide adequate coverage for the relevant fire and explosion scenarios, with respect to both volume and area coverage, horizontal and vertical surfaces. It may be regarded as a fire area and may be covered by several deluge valves. All deluge valves covering the fire area shall be released when fire is detected anywhere in the fire area. This applies also for manual release of any deluge valve covering the fire area. The Fire Water system shall be designed and calibrated such that deluge nozzles will receive water at design pressure not later than 30 s after a confirmed fire signal has been given.
OTK will provide risk assessment regarding the ignition of flammable gas cloud in case of gas leak from production risers. OTK will use Computational Fluid Dynamics (CFD) to simulate different leak scenarios to predict the overpressure due to gas explosion and perform a fire analysis. An explosion analysis will provide protection strategy with the objective of minimizing the explosion risk through the following:
OTK was approached to conduct Fire Risk Analysis. FRA identifies potential fire hazards (i.e. jet fire, spray fire or pool fire) and quantifies the extent of potential consequences. Active and passive fire protection shall be arranged to ensure that a fire is prevented from spreading to other areas within a specified period of time and to protect load carrying structure against critical heat loads. For Major Hazards like riser fires or burning blow outs, the required time period before impairment shall be defined. Shielding of escape-routes and evacuation stations shall be as required to ensure escape from all areas and evacuation from the installation. The fire loads to be considered within an area may be limited through location of ESD or PSD valves.
