gas generator

Dutch critical power supplier DBR is to deliver a gas genset to GDF Suez E&P Nederland’s offshore gas platform E17a-A located in the North Sea.

The 275kVA genset comprises of a gas powered MAN engine and a Leroy Somer air-to-air cooled generator. The system is designed to operate for 1,200 hours between maintenance intervals, according to DBR.

Due to limited space on the manned gas platform, DBR customised the genset design. “By placing the air cooling unit outside the engine room and reducing heavy components to a minimum we have come up with an efficient design that meets our client’s requirements,” said DBR sales manager Henri Hafkamp. The genset uses a single instead of a double frame and is manufactured with robust components to decrease risks of vibration.

The delivery is set for the end of 2014.

DBR recently struck a deal to supply emergency/harbour diesel gensets for six new pipelaying vessels from IHC Merwede.

GDF Suez E&P Nederland has 34 gas producing platforms and an annual gas production of 6 billion Nm3.

GE’s Distributed Power business is to supply 85 MW of on-site power for floating oil and gas production in Brazil.

Four LM2500+G4 aeroderivative gas turbine generators will be shipped to Tokyo-headquartered general contractor Modec, which specialises in the engineering, procurement, construction and installation of floating production systems.

The generators will be installed on Modec’s floating oil and gas production, storage and offloading (FPSO) vessel the Cidade de Caraguatatuba, which will operate in 2240 metres of water in the pre-salt fields off Brazil’s coast.

The generators are planned to power the vessel’s production processes, water reinjection, gas compression and process heating. Non-commercial grade ‘field gas’, produced on-site, will fuel the units, reducing greenhouse gas emissions, according to GE.  

Shipment of the units is planned for late 2014 and installation for 2015, with commercial operation to commence in 2016 or 2017, GE said.

The agreement represents the two companies’ latest vessel set order, following previous orders for projects in Brazil and Africa. In June 2013 GE announced it would supply an earlier group of four LM2500+G4 aeroderivative units for an FPSO platform in Brazil's pre-salt field.

"This latest order for our aeroderivative gas turbines reaffirms GE's leadership in supporting the diverse on-site power needs of Brazil's offshore industrial sector as it develops the country's energy resources," said Lorraine Bolsinger, president and CEO of GE’s Distributed Power business.
