Earlier this year Royal Caribbean Cruises Ltd (RCCL) said it had ordered one 4,200 passenger cruise liner of the new Sunshine class at Meyer Werft in Germany for its Royal Caribbean International contemporary market brand.

However, this week a subcontractor company said it has won an order for two ships of the type, plus options for two more.

“Meyer Werft GmbH, the German shipbuilder, has chosen Koja Oy to supply the air conditioning systems for two giant cruise ships. The contract also includes an option for air conditioning of further two giant ships,” said Koja Oy, the Finnish air conditioning system specliast.

Koja’s statement then said the ships would be built for RCCL and be more than 350 metres in length and accommodate 4,200 passengers each. The contract with Meyer Werft would provide work for Koja until 2015 and if the options are included until 2017, the company noted.
