Ningxia Hanas
One of the largest LNG facilities of its kind in China
In 2011, Technip delivered its first LNG plant in China.
Ningxia Hanas LNG Project is a mid-scale liquefied natural gas (LNG) plant in Yinchuan,
China. It has two trains with a total capacity of 800,000 tonnes per year, based on a
Single Mixed Refrigerant (SMR*) liquefaction process.
The LNG is distributed to
the Chinese market to help
meet the growing demand for
clean energy.
Technip’s operating centres in Kuala Lumpur (Malaysia) and
Shanghai (China) have executed the contract. It is the first
LNG plant to be designed and built by Technip in the
Asia-Pacific Region. It represents a breakthrough into the
mid-scale LNG market and new opportunities for Technip.

An efficient and highly engineered
e-LNG plant
Technip developed the plant design from scratch, starting
from the duty specification provided by the client in the
ITB, through to detailed engineering that included a full
3D model of the plant produced in Technip Shanghai.
Working with Air Products the feed gas is compressed to
reduce the liquefaction overall power requirement. The
mixed refrigerant composition was determined using
components readily available in China. The ITB stipulated
electrical motor drivers for the MR compressor. Technip's
design uses electrically driven two stage centrifugal
machines with cost effective fixed speed motors while
compressor speed variation is provided by hydraulic
couplings. As fuel gas demand is low, all boil off gas from
the storage tanks and truck loading stations is recycled for
reliquefaction thus avoiding wasteful flaring.
The full containment LNG tank was designed taking into
account the seismicity of the region.
Extensive dynamic simulations of the plant were done to
verify the design including during start-up and other
transient states. The models also enabled the reaction of
the process controls to changes in weather condition and
feed gas to be evaluated.
An emulated operator training simulator was provided to
train all newly hired operators off line. This ensured a
smooth start up with minimal loss of production due to
lack of familiarity with the plant.
The main challenges of the Hanas project were:
Weather windows, with extremely low temperatures in
winter, had to be factored into the overall construction
schedule.
For this fast-track project awarded in May 2009, LNG tank
foundation works had to be completed by the end of
2009.
Delivery time of some major equipment to meet
installation schedule.
The presence of existing water wells and underground
pipelines on the project precinct had to be studied
carefully
Transportation limitations: the relatively remote inland
site provided a challenge for the transportation of the
larger equipment items including the cryogenic
exchangers. Technip planned for this right from the start
as part of basic engineering with separation of large items
into manageable packages and reassembly on site.
Pressurised cryogenic fluids including LNG are present
high in the structure. Steel structures may collapse in the
unlikely event of leakage so a number of solutions from
Technip's other LNG projects were examined before
fixing the protection strategy.
Our Kuala Lumpur office offering
broadened
Technip's engineering centres in Kuala Lumpur and
Shanghai, with the technological support from the Paris
office, successfully delivered the Hanas LNG plant.
With this project, Technip has demonstrated it can now
offer LNG capability from its Kuala Lumpur regional centre.

A project risk management workshop was held to discuss HSE issues
as they could impact on the project and mitigation measures were
developed.
HAZOP and other tools were utilised to identify areas that required
control.
HSE in Construction
4 million manhours were worked on site without an LTI (Lost Time
Incident)
On-site Job Safety Analysis was conducted and the results properly
communicated prior to any new work starting.
The PULSE programme was used to align the team behind common
HSE goals.
An incentive programme was put in place to encourage the Project
Team to meet its stated goals.
HSE is also about:
Understanding the location, people and culture
Managing through the employment of competent local people who
can explain and translate the real issues without losing the facts and
emotions
Developing tools that are
practical to use and easy to
understand
Always being there to listen,
guide, support, resolve and
taking control when
necessary.
