11:10 Extending inspection intervals of large industrial gas turbines

Gas turbines suffer from inescapable degradation during service, and require periodic inspection,

maintenance and replacement of parts to ensure continued performance, reliability and safety. The

maintenance intervals are generally specified by the turbine OEM as generic multiplies of annual hours

e.g. every 3 years/24,000 hours for a major inspection, with weighting factors to take into account

operational variables (starts, fuel, trips etc).

Extension of the inspection intervals using risk based assessment allows scheduling of the inspections to

best suit the operation of the plant.

The pros and cons of extending operational intervals are discussed, along with the tools used to assess

the capacity to extend inspection intervals without unduly increasing risk of turbine failure

11:50 Industrialisation of 3D printing for repair and manufacture of gas turbine components

A revolutionary way of manufacturing has emerged in the industry and is considered a game-changer.

Additive Manufacturing (AM) opens up a new dimension to integrated design and manufacturing by enabling

manufacturing and repair of gas turbine components faster and at the same time with higher functionality and

performance.

Siemens Power Generation is utilizing Additive Manufacturing (AM) technology for prototyping, limited repair

and manufacturing of gas turbine components. Siemens PG has been applying AM technology for the repair

of gas turbine components, in one example for burners of SGT-800 industrial gas turbines. The results

showed that the replacement of conventional repair processes with AM provided a significant reduction of

repair time; additionally repaired components were upgraded to the latest burner design.

Another example of Siemens using AM was in manufacturing of advanced burner swirls for the SGT-750. In

this case selective laser melting (SLM) was the only technology able to manufacture this design of the swirl.

The results clearly confirmed the success of AM application for design, prototyping and manufacturing of new

advanced burner swirls.

16:30 CASE STUDY | Gas turbine commissioning, Diamantina Power Station (Mt Isa)

Diamantina Power Station (DPS) consists of 4 x 40MW Siemens Gas Turbine (SGT800) Generator units, 2 x

40MW Steam Turbines, and is supported by an adjacent 60MW Trent GTG. The plant has significantly

reduced the gas consumption of Mt. Isa and the mines in the surrounding area.

The plant commissioning was completed in late 2014, and this presentation covers the challenges faced

during the commissioning process, the major technical issues, and the at times delicate environment inherent

in commissioning relatively large generators on a remote island grid supporting critical infrastructure.

The case study aims to relate the events and insights gained during the commissioning process, by key

members of the DPS commissioning management team.
