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
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.
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,
working hours reached 20 million without having any accidents.
- 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.
- 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.
- 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
- 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.
