Double A, Thailand

SHARING SUCCESS
Double A, Thailand
Double A (1991) Public Company Limited is a leading pulp and paper
maker in Thailand. Double A chose Pöyry as its partner to design and
manage its third paper mill project.
CLIENT & ASSIGNMENT
In a move to further strengthen its
capacity in pulp and paper – in one of the
fastest growing markets in the world –
Double A decided to invest in a third paper
mill. Double A chose Pöyry as its partner to
design and manage the project.
LOCATION
Thatoom, Prachinburi, Thailand
SCOPE
The new UWF paper mill was built at a
brownfield site, located near Double A’s
existing mills. In addition to project
management and co-ordination, Pöyry’s
tasks included basic and detail engineering for the new paper machine and stock
preparation, and supervising the installation and start-up phases of the new paper
machine line.
TIME
January 2011 to October 2012
BACKGROUND
Double A purchased the new paper
machine from PMT Group and began
working on the project in late 2010. In early
2011, Pöyry was brought on to take the
lead in engineering management,
scheduling, standards, detail engineeing
and overall process control– as well as
providing support for commissioning and
start-up.
Pöyry, having previously carried out numerous projects similar in size and scope, was
able to utilise its technical know-how and
expertise to manage the design phase,
specify auxiliary equipment for procurement
and perform the detailed design.
CHALLENGES
With a strict scope, timetable and budget set
right from the start, the challenge was clear:
Pöyry needed to deliver top-notch technical
support to ensure that the productivity and
quality targets for the mill were met.
SOLUTIONS
To keep the project on schedule and ensure
timely delivery of machinery and equipment,
Pöyry took an active role in procurement and
project planning.
Step-by-step throughout the project, regular
meetings were held between Pöyry and
Double A to ensure timely and reasonable
progress. Pöyry’s global resource base was
used efficiently and brought benefits to
the project. For example, while the unit in
Vantaa, Finland, worked on standards and
calculations, the unit in China designed
layouts, process flowsheets and detailed
3D-models. A qualified designer from Pöyry
China was available on-site to make necessary 3D modelling modifications. All this
contributed to clear, cost-effective progress.
BENEFITS
From the beginning, Pöyry and Double
A paid special attention to planning and
scheduling – a move that ensured smooth
“We received significant benefits from
Pöyry’s past experience executing
similar projects. Besides ensuring that
everything went ahead as planned,
they shared their know-how and
experience when it came to dealing
with paper machine manufacturers
and setting up mills” , Double A, PM3
Project Manager.

progress, quick execution and a timely start
up. Planning and procurement scheduling
and utilising resources cost-effectively were
critical success factors in keeping within the
set budget.
Pöyry’s advanced technology further contributed to the project’s smooth execution.
For example, 3D walk-through modelling
accurately visualised the plant’s layout,
adding clarity and saving valuable time,
and DocHotel, a project-specific database
that provided access to the latest project
information at all times.
SUCCESS FACTORS
Throughout the project, Pöyry’s project team
kept things on track. They were quick to
identify and respond to even the slightest
challenges in engineering design or production processes.
There was always an experienced Pöyry
specialist available for each discipline,
which meant daily tasks could be
organised efficiently. This was further enhanced by seamless co-operation
between the client’s production team
and Pöyry’s project team.
As the building phase came to an end,
Pöyry provided support for the commissioning and start-up phases. This en-sured a
fast ramp-up of operations and quick positive cash flow for Double A.
“Pöyry’s team read the situation well
and were able to step back and see the big
picture. They tightened the screws when
required but also gave us a bit of breathing
room when things were running smoothly”,
Double A, PM3 Project Manager.

existing mill-site.
PAPER MACHINE
• production capacity 220 000 t/a
• trim after winder 5200 mm
• design speed 1400 m/min
GRADE
• UWF-paper (cut-size) in the
grammage range 70-90 g/m2
RAW MATERIAL
• 100 % bleached eucalyptus hardwood
pulp from “KHAN-NA” and filler.
• Khan-na is the production of sustainable fiber through cultivation of
Double A Paper-Tree, a hybrid species of
hardwood which is well adopted to
Thailand’s tropical climate. It’s grown in
straight rows along “Khan-Na”, the
unused space between rice paddies.
• This way of growing trees addresses social
issues faced by Thai farmers such as the
difficulty of finding agricultural employment during off- peak season and the
instability of income from planting cash
crops.
