With the commissioning in January 2024 The Icon of the Seas has entered the oceans of the world and made many a cruise ship's heart beat faster. As the new champion in the supership category, it replaces the "Wonder of the Seas" as the largest cruise ship and redefines the cruise adventure. Over 20 decks offer space for up to 7514 passengers and a crew of 2350. The construction costs are also record-breaking at almost 2 billion euros.

Built in the renowned Meyer Turku shipyard in Finland, the cruise giant represents the pinnacle of technological innovation and luxurious amenities on the world's oceans.

LNG and Azipod drives

Icon of the seas AIOn board this majestic cruise ship from the Shipping company Royal Caribbean Internationally, sustainability plays a key role. The progressive Power Type is a prime example of how the Icon of the Seas takes on ecological responsibility. The ship's engines come from the Finnish propulsion specialist WärtsiläThe dual propulsion system can use heavy oil and liquefied natural gas as fuel. An LNG propulsion system burns significantly less nitrogen oxide emissions than traditional fuels, making the ship a big step towards cleaner seas. The LNG on the Icon of the Seas is stored in two 307 m long tanks with a capacity of 27 tonnes.

But the technology is controversial because LNG causes Methane emissions. This has been particularly criticized by environmental organizations. Methane, as a greenhouse gas, is many times more harmful to the climate in the short term than CO2. Since the long-term effects of CO2 Although methane has a more serious impact on climate change due to its longevity and the amount in which it is released, methane is less harmful to the climate overall. And LNG is currently the most climate-friendly ship fuel that exists. The technical development for fuel cell propulsion is planned, but not yet fully developed. The ship is already prepared and can be retrofitted.

The Azipod propulsion systems from ABB take over the propeller drive, which is mounted outside the ship's hull. Unlike conventional propulsion systems, in which a fixed propeller is driven by shafts, Azipod enables the propeller to rotate 360 ​​degrees. This provides high maneuverability, which is particularly advantageous in narrow harbors and when docking. The Azipod drive reduces fuel consumption by up to 20% compared to conventional systems, as it enables more efficient propulsion and reduces water resistance. Three such Azipod drives, each with 20 MW, enable the Icon of the Seas to travel at 22 knots.

The AI on board not only optimizes energy-efficient routes, but also controls the energy consumption of the numerous on-board facilities, from the air conditioning to the elevator systems. Hella Marine equips this unique cruise ship with around 20.000 energy-efficient LED spots that ensure a feel-good atmosphere and safety on the high seas. A sophisticated optical system ensures wide-beam and homogeneous illumination and the digital light control enables precise adjustment of the lighting in the public areas.

Sustainability on the high seas

Icon of the seas EnvironmentThe Icon of the Seas is not only a place of luxury and entertainment, but also a pioneer in sustainability. With advanced waste management and shore power connections, it breaks new ground in environmentally conscious travel and shows that luxury and responsibility do not have to be mutually exclusive.

As part of the Royal Caribbean Group’s SEA the Future program, its newest ships will be equipped with systems such as Microwave-Assisted Pyrolysis (MAP) and Micro Auto Gasification (MAG) are used, which convert solid waste into synthesis gas and use it to generate energy. These technologies not only minimize waste, but also produce valuable byproducts such as biochar, which can be used as a soil conditioner. Recycling programs ensure that more than 90% of the waste never ends up in a landfill. With microwave-assisted pyrolysis, the waste generated on board is also converted into energy on board.

Another highlight is the Royal Caribbean Group’s ambitious goal of reducing food waste by 2025% by 50 This is done by using artificial intelligence to adjust food production in real time and train crew in sustainable practices. These measures have already saved 24% of food waste. In addition, Royal Caribbean Group has expanded its network of green hubs to recycle waste more efficiently and minimize environmental impact. These hubs, including the newly certified Galapagos Islands, have helped keep 92% of waste out of landfills.

Other advanced environmental technologies on board Icon of the Seas help to significantly reduce emissions and fuel consumption. For example, the Waste heat from Engines used to produce a large part of the required fresh water using a seawater desalination plant. 93% of the fresh water is produced on board and treated using a reserve osmosis system.

The green innovations on board this cruise ship are groundbreaking. This also applies to the Air lubrication system. Microscopic air bubbles cover the hull of the ship. The air bubbles are generated by compressors. They reduce fuel consumption by reducing the friction of the ship's hull in the water.

Floating resort with superlatives

The Pearl on the Icon of the Seas is, like the entire ship, an architectural masterpiece and a prime example of the innovative use of modern technology in the cruise sector. The Pearl is hollow and greets passengers as soon as they board as a gateway to the belly of the ship. The spherical pearl represents a connection to the Royal Promenade. This spherical landmark, which extends over four decks and has an impressive diameter of 14 m, impresses not only with its imposing appearance, but also with its state-of-the-art technology and its sophisticated integration into the ship's concept. At its center, a beautiful marble staircase connects the floors with one another.

The pearl gets its shape from a steel ball as a supporting structure. Developed and realized by leading engineers and architects, The Pearl relies on a combination of more than 5000 individually controllable LED lights and interactive media technologythat create stunning visual effects and adapt to the environment in real time. 3600 moving tiles were created with Linear Technology and generate computer-controlled lighting effects. With an integrated sound system of over 1000 W and a total structural load of 20 t, this installation not only serves as an eye-catcher, but also as a central orientation point for passengers exploring the heart of the ship.

The Icon of the Seas is more than just a ship – it is a floating resort, which offers an impressive selection of cabin categories, including the Icon Class. Whether you choose a suite with an exclusive area or enjoy the view from a balcony cabin, everyone will find their perfect home at sea here.
