Working together with AIDA Cruises, Becker Marine Systems has developed a concept for an environmentally friendly LNG Hybrid Barge solution for supplying power to cruise ships lying in port.
Technology partners include SCHRAMM group GmbH & Co. KG, Ingo Schlüter GmbH & Co. KG, EON Hanse Wärme GmbH, and Bureau Veritas, as well as Gasnor AS.
Currently, cruise ships lying in port generate the energy required for on-board operation by using the ships’ on-board diesel engines. The use of these engines results in a high level of pollution containing harmful and airborne substances in the form of soot particles.
The new concept solves this problem by producing energy on the floating LNG Hybrid Barge from environmentally friendly liquefied natural gas (LNG) by means of five generators coupled to combined heat and power engines. The power generated can be fed into the supply grid of the cruise ship as needed. The liquefied natural gas is delivered in modular form, because this is less expensive than bunkering.
An LNG bunker station, ensuring supply at all times, is being built in Brunsbüttel by SCHRAMM group GmbH & Co. KG. Schramm group will also be the operator of the LNG Hybrid Barge at the Hamburg port.
The use of the LNG Hybrid Barge will significantly reduce particle emissions during port visits. In contrast to the diesel engines currently in use, sulphur oxides (SOX) will no longer be produced during port stopovers. The emission of nitrogen oxides (NOX) will be lowered by up to 80 % and the output of carbon dioxide by an additional 30 %.
Another benefit is the year round utilisation of the system. The Hamburg energy provider, EON Hanse Wärme GmbH, is planning to feed the energy produced in the cruise off-season into the municipal grid, thus supplying electricity and heat to approx. 11,000 households (based on four person households).
In autumn 2013 the AIDAsol should be the first cruise ship in the world to be supplied with electricity by Becker Marine Systems’ LNG Hybrid Barge at Hamburg’s HafenCity.
