ANNUAL REPORT OF “TRANSGAZ” MANAGEMENT INDIVIDUAL ...

SNTGN “TRANSGAZ” SA Medias Annual Management Report for 2007
with the pipelines and having worn-out equipment generating higher power
consumption.
The compressor capacity is provided by 6 gas compressor stations located on the main
transmission directions. Such compressor stations are endowed with equipment and
installations manufactured in the 70s, physically and morally worn-out and usually
unlikely to reach the performance required by the transmission parameters.
The gas dispatching within the NTS is done by operations, in the interconnection
nodes of the main pipelines. Such nodes are provided with manually actuated
operation valves and parameter surveillance equipment, most of them being worn-out
from the point of view of performance and safety of operation.
Gas odorisation is generally carried out by “evaporation-type” centralized systems
failing to ensure continuous and controlled odorization which could cause under- or
over-odorization and implicitly increased odorant consumption.
One should notice that although the tangible asset base is rather old, the real technical
conditions of the NTS are properly maintained as a result of accurate maintenance,
rehabilitation and modernization programmes (current repair works and overhauls).
Such programmes were focused on finding state-of-the-art solutions for the choice of
proper technologies and equipment and provided the fact that such
maintenance/modernization/upgrading works would last for a long period because of
the high value of works.
2.2.2. Achievement of the maintenance programme
The asset management applied to the gas transmission activity is a component of the
NTS strategy and aims at ensuring quality gas transmission services under the
European standards and within acceptable risk limits.
The NTS capacity maintenance activity, coordinated as to ensure the level of
performance required for providing maximum operability with minimum costs, is to be
considered within this context. Developed based on the Maintenance Provision
Programme, such activity was structured on 2 chapters: “Maintenance works” and
“Maintenance services”.
The total value of the Maintenace Programme for 2007 was of lei 83,225,001
integrally covered by own sources. This programme included the kick-off of the
Transmission “0” System, by the implementation of a pipeline rehabilitation
programme in the main consumption directions, so that it could operate at 40 bar.
The maintenance programme consisting of the above-mentioned chapters, the
directions of action according to objectives and services and their percentage share are
all shown in the following table:
