Bremen-based SAACKE Marine Systems has introduced the GCU evo, following just under a year’s development programme.
It is a further development of the the company’s gas combustion unit (GCU) consisting of a combination of the combustion unit with a modified surface burner.
The abbreviation evo stands for ‘evolution’.
"In order to take into account the ever decreasing space available in the engine room of LNGCs, we have now designed this system solution with significantly smaller dimensions with the same or even improved performance," Bernd König, SAACKE's Sales Director Offshore & GCU Systems explained.
In addition to saving space, the new model offers further advantages, such as emissions reduction, due to special cold flame technology and digital remote maintenance.
These are important aspects in the globally growing LNG market for shipyards, owners and charterers of LNGCs and bunker vessels, on which a GCU must be installed as standard for the safe transport of LNG, the company claimed.
An optimised design not only reduces the required space on board, but also the installation costs. In addition, maintenance costs can be reduced, due to a less complex system. No special foundation is required for the GCU evo, which has an output of 5.5 to 63 MW.
The system can be mounted directly on the ship’s deck as a stand-alone unit with a simple installation. There is no need to connect it to other components.
"In addition, due to its compact design and functionality, the surface burner offers a short flame and requires a smaller number of blowers. In addition, due to the lower pressure loss on the air side with the surface burner, a smaller motor output is required for the blowers and the power consumption is minimised as a result.
“All in all, a smaller footprint and height are needed and more space is freed up for other components in the shipyards," König added.
By using remote control, operators can also perform online diagnostics from the shore, for example, for preventive remote analysis.
While the SAACKE headquarters in Bremen headed up the engineering and project organisation, a test plant was built at the Chinese site in Qingdao. It can burn 800 kg/h of methane and was used for product development.
Ready for series production, the GCU is available in different output sizes from 0.4 to 4.5 t/h methane combustion.
The scope of supply includes the GCU system, including burner, control system, gas train and blower, as well as spare parts service. Installation and commissioning will be carried out in sections. SAACKE also offers training courses.
"Our basic GCU model will also remain in our portfolio, as it also covers output ranges of up to 6.5 t/h of methane for exceptional applications and can burn oil," König said.
