Koja solutions in the Harmony of the Seas

A world of tastes, aquatic excitement spanning ten decks, ice skating, simulated surfing, musicals, parades, unforgettable 3D adventures – this and much more can be experienced aboard the latest entry to the Oasis series of luxury cruisers, and the biggest entertainment centre ever to sail the oceans: the Harmony of the Seas. Koja engineered the air conditioning solutions and supplied the air conditioning systems to the luxury cruiser commissioned from STX Europe shipyards by the Royal Caribbean International.

"As the deployment support in the project, we prepared the equipment for use after production and installed it to the ship. Our products are always customised to meet the requirements of each project", project engineer Juha Aro of Koja Marine tells us.

The Harmony of the Seas made her first voyage from the STX France shipyard in Saint-Nazaire to her home port of Barcelona in May 2016. Starting in autumn 2016, the ship will cruise the Caribbean.

Harmony of the Seas: Fast and safe on the seven seas

Decorated in delicate tones and timeless design, the Harmony of the Seas is a cornucopia of unforgettable experiences in fashion, entertainment, relaxation and taste perfect for all ages. And to all this, fresh indoor air adds the finishing touch. Energy-efficient air conditioning solutions tailored precisely to the needs of the different spaces and facilities of the ship ensure passengers are comfortable in all parts of the vessel. The air conditioning solutions are designed to accommodate both the spacious promenades as well as the more confined spaces, such as the luxury suites and kitchen facilities.

Kari Pihlajaniemi, Technical Project Manager in charge of technical engineering of ships including Harmony of the Seas and Oasis 4, applauds Koja, his reliable partner over the years in various luxury cruiser projects.
"Koja has always performed their role in the projects with excellence, proving that they really are the number one systems vendor in their industry for demanding projects. The professionalism and flexibility of Koja employees is top of its class, which has been very important especially when exceptional situations and circumstances have been encountered."

The collaboration is set to continue: STX France has ordered air conditioning systems to the fourth ship of the class, the Oasis 4, set to be delivered to the customer in March 2018, from Koja. Koja has also engineered air conditioning systems and automation solutions and supplied the air conditioning systems to the sister ships of the Harmony of the Seas, the luxury cruisers Oasis of the Seas and Allure of the Seas, both built in Turku.

And that’s not all...

The Harmony of the Seas brings the seascape to the passengers in a novel way: interior cabins without windows have virtual balconies with real-time views of the sea. The passengers can enjoy beautiful sunrises and constantly changing seascape in the privacy of their own cabins. The ship keeps you energetic from morning to night: efficient air-conditioning helps your mind stay alert to take in new experiences. Wireless network connections that utilise satellite data communication for the Internet link makes it easy to share your moments with your loved ones at best data transfer speeds available in the seven seas.
