Pre Bid Engineering Support for EPCC Turnkey Contract for New Fire Water Tank With Pumping Station at OQ Methanol Plant Project,Oman

OQ is one of the largest integrated energy companies of Sultanate of Oman and the group focuses on facilitating local and international private participation in the oil and gas sectors to increase value for shareholders and reap greater benefits for the nation.

OQ Methanol Company (OQ MTH) owns and operates a 3,000 MTPD Methanol plant and the supporting Utilities & Off-sites plant at Salalah, Sultanate of Oman. The principal raw materials for the plant are Natural Gas and Sea Water. All Utilities (desalinated water, de-mineralized water, steam, cooling water, power, and nitrogen) are produced within the integrated Utilities & Off-sites plant. Natural Gas is used as feedstock and fuel. Sea Water is used for producing desalinated water and as cooling media for process needs. The plant was commissioned in April 2010, and it has successfully completed two turnarounds in April 2014 & April 2018.

The plant is provided with a fire water system with Fire Water Pond (20-W2601), having a capacity of about 9,400 m3 with HDPE liner. The sidewalls are concreted and the soil underneath the liner is compacted. The connection of the HDPE liners are overlapped and seal welded. The water is being stored and used for fire extinguishing purposes. The maximum firewater demand during the normal plant operation is about 2366 m3/hr.

In case of fire, two jockey pumps and the three fire water pumps shall be started automatically. The spare jockey pump shall be started automatically by fail position signal of the first jockey pump. In any cases, the network pressure shall be maintained min. 7 barg at the remotest and highest point.

However due to the water loss and seepage issue in the Fire Water Pond, OQ MTH plans to build a new fire water storage system with New above ground tank along with new Pumps station and all associated auxiliaries including tie-in with existing fire water network.
