The main equipment of the power plant is arranged in two identical power blocks, each consisting of two gas turbine generators, bypass stack with hydraulic diverter damper, two heat recovery steam generators with main stacks, one steam turbine generator, and one air-cooled condenser. Each gas turbine and steam turbine generator is provided with its own dedicated step-up transformer, rated for the generator output at site ambient conditions, which steps up the voltage from 21 kV to 400 kV. There are no significant main process interconnections between the blocks and therefore they operate independently, with the exception of some plant systems which are shared or interconnected, such as medium and low voltage (MV/LV) common electrical systems and plant control systems. The main equipment of the plant is listed below.
The operation & maintenance of the plant is contracted to the operator.
The operator has sub-contracted the entire scope of the O&M Agreement to NOMAC Oman. In addition to the IBRI IPP, NOMAC Oman also operates and maintains the ACWA Power Barka IWPP, comprising of a 427MW CCGT power plant, a 20MIGD multistage flash desalination plant and two seawater reverse osmosis desalination plants of 10MIGD and 12.5MIGD capacity, Salalah II IPP and Sohar 3 IPP. The long term maintenance of the gas turbines is subcontracted by NOMAC Oman to Ansaldo.
NOMAC Oman is a subsidiary of NOMAC. NOMAC was founded in 2005 and is firmly established in the GCC, North Africa, and South, Middle and East Europe regions, providing high-quality operation and maintenance services for power production and water desalination projects, regionally and worldwide. NOMAC’s broad range of services includes, but is not limited to, long term operation and maintenance, major overhaul of high-tech plant equipment, and development of plant-specific standard operation and maintenance procedures. In total, NOMAC is responsible for the operation of a portfolio of 28.0GW of power generation and 5.3 million cubic meters per day of desalinated water production, with over 2000 employees as of August 2019. NOMAC is the largest private sector potable water producer using desalination process in the world. NOMAC operates plants responsible for 40% of water and 15% of electricity demand in Saudi Arabia.
At AGC, safety is a core value that remains one of our top priorities. We are committed to the safety of our employees, our contractors and our local communities. Our safety programmes are designed to reinforce the safety culture among all personnel. We operate on the principle that all incidents are preventable if everyone completes each task safely. Our programmes engage everyone by incorporating safety measures specifically tailored for each of three targeted groups: department heads and managers, supervisors and engineers. Leadership plays an important role in making our incident and injury-free workplace a reality. Leaders participate directly in coaching sessions, safety discussions, and workshops focused on ensuring safe and secure operations.
Another channel of direct management engagement is the AGC HSE (Health, Safety & Environment) Committee chaired by the CEO. This committee discusses the monthly HSE highlights, major incidents, and lessons learned, and conducts monthly site visits. The Committee also organises forums in which operators and maintenance personnel meet to discuss areas of mutual safety concern and share experiences. This is also supported by a network of safety champions and coaches that are embedded in all assets and in all shifts.
At an operational level, AGC and O&M have an integrated management system that covers HSSE and has been certified to the ISO and OHSAS standards since 2017.
AGC and O&M offer rewards programs to motivate stakeholders to abide by the company’s HSSE policies. They include recognition, bonuses and cash incentives for good performance and rewarding reporting of near-misses. We believe that incentives combined with zero-tolerance enforcement of standards are instrumental in driving HSSE in action and fostering a safety culture across AGC.
