On the FPSO Carioca MV30, two additional SGT-A35 turbines will be used to drive DATUM compressors. Siemens says that the same gas turbine package can also operate in mechanical drive mode for compression or pumping service. Compared to the conventional Industrial RB211 predecessors, the SGT-A35 offshore package is 30% lighter with a much smaller footprint. In this configuration, the free power turbine can direct-drive an electrical generator at either 60 Hz or 50 Hz frequency without the need for a step-down gearbox, which results in substantial weight and space savings, according to the company. Siemens says that high power density is achieved through a system architecture that incorporates a lightweight, proven aeroderivative free power turbine module optimized to operate at synchronous speed to a 2-pole A/C generator. MODEC will engineer, construct, and operate the facility.įour SGT-A35 packages will be used to provide power generation for the vessel.

The facility will be deployed in the Sépia field owned by Petrobras.

In 2018, Siemens supplied six SGT-A35 (GT30) gas turbine packages for the FPSO Carioca MV30, located in the presalt region of the Santos basin approximately 250 km (155 mi) off the coast of Rio de Janeiro, Brazil. Siemens says that its SGT-A35 gas turbine (formerly known as the Industrial RB211) has emerged as a preferred solution for delivering on key performance indicators (KPIs) in today’s offshore environment. The latter is especially important for floating, production, storage, and offloading (FPSO) vessels, as reduction in module weight and footprint can reduce facility development costs and increase options for topsides configurations. Gas turbines meet the needs of project developers to reduce emissions and minimize the size and weight of topsides. In response, the demand for gas turbine solutions that can efficiently deliver the power to exploit resources in deeper waters has grown immensely. In recent years, offshore operators have faced greater pressure to reduce capital investment and increase production capacity.
