Alstom to access Chinese turbine market with GT13E2 license agreement
July 1 2013 -
Alstom has recently signed a long-term agreement with Harbin Turbine (HTC) to license its GT13E2 gas turbine for manufacture, assembly and sales in China. As per the agreement, HTC will manufacture and assemble the GT13E2 gas turbine in China, while Alstom will supply some of the critical components.
Through the deal Alstom is expecting to gain better access in the Chinese market and supply its GT13E2 E-class turbine through HTC. The two companies are also expected to set up a service joint venture to serve the Chinese GT13E2 customers.
Most steam turbine vendors use a vacuum gland condenser system to ensure that air enters the last section of the steam seal, thus preventing steam from entering the bearing bracket and contaminating the oil system.
Siemens F-class turbines begin commercial operation in California

GE’s LM2500+G4 turbines to power new floating production platform offshore Brazil
June 25 2013 -
GE will soon provide four LM2500+G4 aeroderivative gas turbine packages for a new floating production, storage and offloading (FPSO) platform offshore Brazil. The equipment will be supplied to Mitsui Ocean Development & Engineering Co., Ltd. (MODEC), a general contractor specializing in engineering, procurement, construction and installation of floating production systems. The FPSO, owned and operated by MODEC, will be installed in 2,240 meters of water depth in the pre-salt fields offshore Brazil.
Lower stiffness ratio can improve seal life in centrifugal pumps
June 21 2013 -
Conventional centrifugal pumps, those with mechanical seals, need to provide a stable environment for the seal to obtain the maximum life from the seal. Part of this stability comes from keeping the seal faces parallel to each other with minimum vibration. In single stage overhung pumps, the shaft is a cantilevered beam with a circular cross section supported by the bearings with a concentrated load, the impeller, at the end.
