The project of North LPG Tanks Farm in Ahmadi Refinery is one of KNPC vital projects that aims at raising storage capacity to meet the expected production increase of fourth and fifth gas train after being completed. The tanks are also used to store the gas produced by Gas plant in MAA as well as the first and second gas pipelines.

 

The project harmonizes with KPC international marketing strategy besides meeting local demand for petroleum products especially gas for either home consumption, producing electricity or other Kuwaiti industries such as petrochemicals where gas is used as feedstock in manufacturing olefins and aromatics. 


KNPC started the project in April 2011 along with the main contractor, the Korean Company GS E&C, and 87 percent of the project is completed now. The project is divided into three stages in which the first stage was completed on time, in 2013, and it covers main electricity works of the project. The last two stages are expected to be accomplished in September and December 2016.


The different works of the project still progress well according to schedules and they did not influence production operations, too.
 
 
Furthermore, safe working hours reached 20 million without having any accidents.
 
 

Project Details

   

- The contract value is KD 156 million.

- The assigned area for the project in MAA estimated 350,000 square meters.

- Building ten tanks each one accommodates 72 thousand cubic meters of gas.

- The farm includes 10 tanks five for butane and 5 for propane and the 10 tanks were built after demolishing 6 old ones.

- In addition to tanks, there are 9 cooling compressors, two sub-stations to boost electricity and Instrumentation Control Center "Satellite House" at the project site.
 

Distinguished Protection

- Tanks are built by a new technology as they lifted 2 meters and a half from the ground. This system replaced electric heaters system which is used for protecting tanks from ice and moisture. According to the new technology, heat exchanging process occurs directly with external atmosphere and it decreases cost and burden of periodic maintenance.

- Tanks are designed with two-wall technology to increase thermal insulation and reduce the possibility of tank content leak. It is also resistant to natural disasters such as earthquakes- God forbidden- and the walls are separated with insulating materials fit the different conditions of weather and stored material.

 

- Installation of additional roofs to reduce gas emissions and benefiting from emitted gases in South KNG tanks at MAA, which were not included by demolition process.


Outstanding Works

- Upgrading the new loading pier in harbor no. (1) and (2), which will enable the company to load ships with both gas and fuel at the same time and shortening the required time for loading & ships wait. Such a step also contributes in reducing the cost and saves time as well.

- Roof of each tank weighs 875 tons wherein walls & roofs were built simultaneously in order to save time. After completing the process of installing the double walls roofs raised by giant compressors taking 3 hours for raising each roof.
 
 
- Each tank installed on a base stands on 212 pillars, lie 20 meters under the ground, and it is a new technology in the company, too.
 
 
- Some difficulties emerged during execution such as the existence of water and rocks that interrupted some works and damaged digger.
 
- Project execution also faced various technical problems, some of them during the process of demolition, since the company's expertise was in construction and it was the first time to demolish large old tanks containing flammable remains. It needed to deal with them carefully to ensure the safety of employees and property of the company; especially the site contains pipelines linked with production operations that cannot be halted.
 
 
- Problems included lack of information about some pipelines and electricity cables lying under the ground, as it is difficult to obtain engineering charts of the area that was part of KOC and established in the fifties or sixties of the last century. MAA became under the management of KNPC in the eighties of the last century as well.
 
- Detailed engineering and construction works executed by KNPC employees without hiring an advisor. However, the qualified cadres of the company observed and followed up the different stages of execution from A to Z.
