Sasol Open Cycle gas turbines Secunda, South Africa

The 240MW open cycle gas turbine (OCGT) power plant comprises 2 industrial gas turbines (GE PG9171E) initially in simple cycle with addition of HRSG’s for process steam as a second phase.

The simple cycle plant together with the conceptual design of the second phase was completed by SDE.

SDE were appointed as engineering Sub-Contractor by the EPC Contractor, Group 5. The SDE scope included engineering design and implementation supervision of the full scope of mechanical, process, electrical and C&I services.

Al Hartha, Basarah, Iraq

The Iraq project is a fast track, emergency power project with six simple cycle aero-derivative mobile gas turbines (GE TM2500). The gas turbines have a site rating of 20MW each with overall plant capacity constrained to 100MW by the utility grid. The gas turbines are mounted on trailers allowing rapid deployment.

A key aspect of this project was the fast track implementation. The project was a greenfield project with extremely unfavourable ground conditions. 24/7 platform construction allowed completion in 10 weeks with all civils complete for GT and BOP equipment arrival on site 12 to 14 weeks after construction start.

The project including a 132kV switchyard, overhead power lines and 3km gas supply pipeline was completed in 7 months.

The SDE scope included engineering design and implementation supervision of the full scope of mechanical, process, electrical, C&I, civil and structural services.


Al Hartha Repowering Basrah, Iraq

The Al Hartha project was repowered with the latest generation TM2500+ Gen 8 mobile gas turbines in 2017.

The project scope included changes as required to support 4 bY TM2500+ Gen 8 GTs with provision for a further 2 units in future.

The project included a research trip to a completed TM2500+ Gen 8 plant in Indonesia to ensure complete understanding of the TM2500+ Gen 8 technical requirements and obtain plant operator input to ensure optimum plant design.

The plant progressed to GT arrival at port in Iraq and mobilisation of GE TAs. It did not proceed to final installation due to regulatory hurdles. The SDE scope included engineering design and implementation supervision of the full scope of mechanical, process, electrical, C&I, civil and structural services.

IBOM IPP, Nigeria

The Ibom IPP Power Plant design comprised three simple cycle gas turbines (One new GE Frame 9 E plus 2 by aftermarket GE Frame 6B gas turbines) giving a total output of 180 MW.

The plant was designed to operate in island mode with limited back-up from the grid. The ability to synchronize with the Nigerian grid (NEPA) was also part of the design scope.

SDE were appointed as engineering Sub-Contractor by the EPC Contractor, Group 5. The SDE scope included engineering design and implementation supervision of the full scope of mechanical, process, electrical and C&I services.

Xaris IPP Project, Walvis Bay, Namibia

The Xaris IPP Power Plant comprises six simple cycle gas turbines (GE LM6000PC) with evaporative cooling and including provision for future conversion to mid-merit or peaking combined cycle operation. The plant has a simple cycle output of 300 MW. The fuel source is regasified LNG from a FSRU located in the new Walvis Bay north port extension.

SDE were subsequently appointed as engineering Sub-Contractor by the EPC Contractor, Guarantee Khosa Energy (Turkey). The SDE scope included engineering design and implementation supervision of the full scope of mechanical, process, electrical, C&I and civil structural services. A significant Early Works stage is in progress to ensure the project can proceed to construction on site immediately following financial close. The project has a 16 month construction period for the initial simple cycle phase.

The project Early Works phase included preparation and bidding of the Works Packages to enable orders to be placed immediately on financial close, minimising construction time. The project was shelved by the Nambian utility, NamPower in 2018 due to increased regional electricity capacity being available.

Aba IPP, Nigeria

The Aba IPP Power Plant design comprises three gas turbines (GE LM6000PD) with inlet air chilling giving a total output of 135 MW at the design site conditions. The plant was designed to operate in island mode with limited back-up from the grid. The ability to synchronize with the Nigerian grid (NEPA) was also part of the design scope. SDE were appointed as engineering Sub-Contractor by the EPC Contractor, Group 5. The SDE scope included engineering design and implementation supervision of the full scope of mechanical, process, electrical and C&I services.

Az Zour Power Plant, Kuwait

The Az Zour IPP power plant comprises five simple cycle Alstom GT13 gas turbines delivering 800MW. SDE undertook an Owners Engineer role including full 3D modelling of all construction drawings and OEM information. A key role was identification and resolution of clashes and outstanding information to achieve an overall fast track deadline.

BUA Cement, Nigeria

The BUA cement power plant comprises 3 by Siemens SGT500 gas turbines providing 50MW captive power for a cement plant. The plant operates on gas, HFO or distillate fuel. The plant was undertaken as managed Work Packages contracted directly by the Cement Plant Owner. SDE was responsible for full scope of services including Civil, Structural, Process, Mechanical, Electrical and Electronic Engineers.
