Sarawak Energy downplays security risks at mega-dam
07 July 2014
A confidential assessment of the turbines of the Murum Dam reveals severe security issues – Sarawak Energy asked to put
safety first and stop all preparation works for further dams
(SARAWAK / MALAYSIA) Late last week, the whistleblower website Sarawak Report uncovered severe security issues at the
controversial Murum Dam in Sarawak, Malaysia. A leaked assessment of the turbines of the dam concluded that the “turbine
runners are not suitable for installation and operation”.
Norwegian consultancy company Norconsult was asked by Sarawak Energy to assess the turbine runners of the Murum Dam. A
‘runner’ turns the turbine as the blades of the turbine are pushed by the flowing water. The turbine runners at the
Murum Dam have cracks and pores and the quality of the welding and grinding is judged as poor according to the
assessment. As the defects are located in “high stress areas”, the “defects could likely be the starting point for
fatigue cracks”. These cracks in turn could lead to small or catastrophic break downs. Flooding of the power-house and
fires are described as possible worst case scenarios in the assessment.
Instead of communicating these security issues after the completion of the assessment in March, Sarawak Energy decided
to perform highly unusual repair works at the already installed turbines to cover up the risks. Sarawak Energy’s dam
building contractor Three Gorges Development Company is asked to do the repair at the site in order to keep the
commissioning schedule on track to the expense of the workers’ safety. Professor Daniel Kammen from the Berkeley
University had a look at Norconsult’s findings and Sarawak Energy’s intention to handle the problem at the dam: “I would
be totally amazed if it was possible to do a proper alignment in situ. This looks clumsy, I have not seen this type of
repair done in such a way before”.
Confronted with the leaked assessment of Norconsult, Sarawak Energy decided to downplay the current security risks at
the Murum Dam. Sarawak Energy’s CEO Torstein Dale Sjotveit claimed: “The problems found on the turbine runner are
rectifiable” and the Murum Dam “will be completely safe”. This wording clearly confirms that there are serious security
issues at the moment.
These problems at the Murum Dam do not only shed a bad light on Sarawak Energy, but also on its engineer adviser
Norconsult: In May this year, the anti-dam network SAVE Rivers from Sarawak visited Norconsult’s headquarters in Norway,
but were kicked out. Norconsult’s CEO John Nyheim did not want to meet with the dam-affected representatives. He rather
helps Sarawak Energy to cover up severe security issues at one of the dams.
The Bruno Manser Fund demands Sarawak Energy and Norconsult to be fully transparent and specifically asks
1) to stop all preparation works for further dams in Sarawak immediately
2) to provide the full assessment on the turbine runners to the public
3) to put the safety of the dam workers and the surrounding communities first and to publicly explain how this can be
assured
4) to explain how the discovered problems will affect the long-term performance of the Murum Dam as well as their
potential effects on the downstream Bakun Dam.
