Power plant products | Compact monitor for small GTs


Condition monitoring specialist Sensonics has developed a ‘cost-effective and compact DN26 G3 protection monitor’ to provide effective protection for small to medium sized industrial machinery.


The monitors have been installed by Centrax, which supplies gas turbine- powered generator packages based on 3–15 MW core engines by Siemens. Centrax have used the protection monitors to replace obsolete, failed or unreliable products in the field. The Sensonics unit offers a dedicated speed monitor channel which can also be utilised as a phase reference for further harmonic analysis of the vibration signals. The sensor interface is programmable to


accept IEPE type accelerometers/velometers, proximity probes (API 670 standard), and active/ passive speed probes while the sensor signals


are available via a buffered interface to provide further detailed analysis if required. Three alarm relays are available as standard (expandable to up to seven relays via a digital interface), one dedicated to indicate module and sensor integrity. The other two relays are fully programmable across the alarm criteria selected and all three input channels measured values are available via a 4-20mA interface. The unit is available with Ethernet communications as standard, permitting configuration either locally or remotely through the in-built webserver and offering Modbus over TCPIP for connecting measured data to other plant-wide systems.


Voith Hydro opens new centre of competence


Voith Hydro has officially opened its newly established centre of competence for generator components in Bosnia and Hercegovina. The location in Lukavac (Tuzla) will be serving western markets; from North and Latin America to Europe and Africa.


Its location is only 1.5 hours flight time from Voith’s German headquarters in Heidenheim, giving it close access to the company’s central technology


department, where essential R&D functions for generator components are based. Additionally, Voith Hydro is in close collaboration with the Bosnian facility of ELIN Motoren, a Voith company, which is producing motor


and generator coils as well as wind generator components in the immediate neighbourhood. Pole production at the facility began in 2021 and initial production tests were performed by February 2022. After successful acceptance


tests, pole production started with first orders for hydropower stations in Belgium, Luxembourg, Sweden, and Switzerland. Production of bars and coils also underwent demanding life-cycle simulations and high-voltage tests. These have now been completed, to meet international standards, but also the company’s higher internal quality aspirations.


“With this facility, we bundle our competence for bars, coils, and poles. The location in central Europe is ideal to serve not only the European market but also Africa, the Americas, or even beyond”, says Dr Tobias Keitel, president and CEO of Voith Hydro.


New jack-up vessel for WTG installation at Hornsea 3


Ørsted has appointed Havfram Wind to install turbines at its Hornsea 3 offshore windfarm off the coast of eastern England, starting in the autumn of 2026. Havfram will be utilising one of its newly built NG20000X jack-up wind turbine installation vessels with a 3.25-ton crane. The 2862 MW Hornsea 3 will consist of up to 231 offshore WTGs, located within a 696 sq km area, approximately 120 km off the Norfolk coast and 160 km off the Yorkshire coast.


Patrick Harnett, Ørsted’s vp for execution programmes, commented: “Delivering an offshore wind farm of the size and scale of Hornsea 3 requires the development of strong, collaborative relationships with our contractor partners and the realisation of new supply chain capacity. We [are signing] our first contract with Havfram, bringing a new cutting-edge vessel to the offshore wind market.”


Martin Degen, commercial director and vp of 38 | April 2023| www.modernpowersystems.com


Havfram Wind emphasised the importance of Hornsea 3 for the global offshore wind market: “We are extremely thankful for getting the opportunity to prove our competence with a project like Hornsea 3. We are confident that we have not only the right assets but also the team to fulfil such a large construction job. Hornsea 3 represents an important contribution to the rapidly growing renewable energy capacity in UK, the largest energy market in Europe.”
