Wärtsilä, a global leader in complete lifecycle solutions for the marine and energy markets, has signed a long-term maintenance agreement with Prosafe, the world's leading owner and operator of semi-submersible accommodation vessels also known as flotels. The 10-year agreement was signed in October 2015 and covers the diesel engines onboard Prosafe's new build flotel Safe Boreas. Maintenance agreements for Prosafe's three other new build flotels - Safe Notos, Safe Zephyrus and Safe Eurus - are expected to be signed later in 2016. Flotels will be delivered in 2015-2016. The scope of the signed maintenance agreement is comprehensive. It includes all services from the supply of spare parts and maintenance work to fast online support and assistance for Prosafe's vessels.
