RCI’s Passion & Pulse To be LNG Powered

March 24, 2017

Royal Caribbean’s fourth ‘Quantum’ class ship (actually called ‘Quantum-Plus’ class) will be named ‘Passion of the Seas’ and will be delivered by Meyer Werft, Germany, in 2019.

Their fifth ‘Quantum-Plus’ class ship, to be named ‘Pulse of the Seas’, will be deliver in 2020.

It has been strongly rumored that both ships will be LNG powered, in keeping with many newbuilds form other major cruise lines, such as Carnival and MSC.

Royal Caribbean’s next class of ship, currently shrouded in secrecy, know as ‘Project Icon’ will also be LNG powered.

What is LNG?

Using LNG to power ships is not a completely new idea. However to date, LNG use has been restricted to smaller vessels operating rather short runs. This is due to the large size of fuel tanks required and the few bunkering facilities available. However it is a new idea for cruise ships and certainly for a megaship design.

LNG is superior to pipeline gas in quality. This is because LNG is purer, has more methane as well as other energy content, and also because of its chemical structure since it has a stable composition. Its combustion generates no unburned residues, particulates or soot, and releases less greenhouse gas than traditional marine gas oil (MGO). Future maritime emissions regulations, especially in sensitive environments are likely to demand this. Perhaps the most appealing aspect about LNG is that under the right operating conditions it can reduce fuel costs.

In addition, using  LNG can double the maintenance intervals, because the gas is so clean,  ship owners may get  25,000 hours between maintenance intervals, maybe more, opposed to 12,500 hours with standard fuel.

Here is an interesting example: VIKING GRACE is a European passenger ferry (2013, 57,000gt, STX, Finland) powered by LNG. Gas take up more space than fuel-oil. In fact six times more space. Therefore large tanks for the gas are located on deck, of the ferry, to save space in the hull (See image above).

However the renderings of  Carnival’s newbuilds do not appear to have LNG storage tanks on the deck.

LNG cruise ship ‘concepts’ have been around a long time. The renderings below are a design by Wärtsilä, the marine engine company.

Interestingly the concept ship uses drive shaft technology, rather than pods. The LNG tans are located internally, below the funnel area.

The engines on-board the new Carnival ships will not exclusively be powered by LNG, but will be ‘dual fuel’ being capable of burring both LNG and liquid fuel, and combinations of both at the same time. burning exclusively LNG could be saved for environmentally sensitive areas. This would reduce the fuel storage space required.

Symphony of the Seas

Oasis (M.Oliver)

Oldest Sister: Oasis of the seas

The name for Royal Caribbean’s fourth Oasis class ship has been leaked.

The release allegedly came from FlowRider, Inc, which manufactures Royal’s signature surf simulators.

In the line’s exclusive announcement that the fourth Oasis-class ship will feature two simulators, the name Symphony of the Seas was revealed. The post has since been taken down from the website.

There is even an image from the shipyard which shows a partial name on the ships hull: “Symph…” so I take that as proof positive.

The ship is currently under construction and like its sister ship, Harmony of the Seas, will sit amongst the largest cruise ships in the world.

There has not been any details on itineraries or the ship itself revealed as of yet, although the line’s International CEO, Michael Bayley, confirmed in an interview that Royal’s next  ship will be coming to the United States, following a brief European summer season.

Bayley has also recently referenced the fourth in the line’s Quantum class by a name unheard of until now: “In 2019 we will have Quantum Plus.”

RCI Announce Project ‘Icon’ LNG Newbuilds

October 10, 2016

smaller

Royal Caribbean International has today announced that its newest class of ships will be powered by liquefied natural gas (LNG) and will introduce the use of fuel cell technology.

These innovations will dramatically reduce greenhouse gas emissions.

The cruise line said that it has signed a memorandum of understanding with shipbuilder Meyer Turku for the new class of vessel under the project name “Icon.” The vessels will be delivered in the second quarters of 2022 and 2024.

The ships will carry 5,000 passengers. They are expected to also be able to operate using conventional maritime fuel as a well, for ports without the necessary LNG infrastructure.

Icon is the first new ship class announced by RCI since Celebrity Cruises’ new Edge class, which debuts in 2018. (Also shrouded in secrecy)

RCI said it will begin testing fuel cell technology on an existing Oasis-class ship in 2017, and will also run progressively larger fuel cell projects on new Quantum-class vessels being built in the next several years.

Malcolm says: Wow, exciting news – another new ‘class’ of ship from RCI. I was not expecting this so soon after the introduction of the ‘Quantum’ class (see video below). 

Mind you building LNG ships simply follows suit with Carnival and MSC who also have big LNG ships on order. Let’s also not forget that Quantum’s ‘Dynamic Dining’ system was a flop – maybe they are keen to move on?

RCI are masters of secrecy, so I don’t suppose we will get any more details for months/years.

We know very little facts about Icon, apart from she will carry 5,000 passengers, but is that lower berths or full capacity? Even the all-important gross tonnage has been omitted form some press releases.

However several sources suggests that ‘Icon’ will be 200,000 gt which makes  the 5,000 passenger figure  look like a lower-berth statistic. (A 200,000 gt ship with 5K passengers gives us a similar space-ratio to ‘Harmony’)  This size of ship is in keeping with Carnival, MSC and Genting’s newbuilds, so this size sounds very likely to me.

In contrast, the ‘Quantum’ class is  approximately 168,00 gt., carrying 4,905 passengers – all berths. The Oasis class is around 227,000 gt carrying 6, 780 – all berths. Icon would sit in-between the two, in terms of gross tonnage.

I wonder what new innovations RCI will come up with this time? How do you beat a park, bumper-cars, skydiving simulator and an observation pod?  It must get increasingly difficult  to keep being innovative. However, if Icon is a 200,000 gt ship, there will be plenty of room for wow-features onboard, if they want.

The arrival of these new ships may well see the departure of  RCI’s older tonnage.

Majesty has now been in the fleet for 24 years, Grandeur 20 years, Enchantment and Rhapsody 19 years and Vision 18 years. Although the life expectancy of a cruise ship can be 30+ years, in six-eight years time, when the ‘Icons’ arrive, RCI’s older tonnage will look even smaller and more dated.

The pressure is now on NCL to go bigger and go LNG.

STOP PRESS: On October 2016, Royal Caribbean filed a trademark application with the United States Patent and Trademark Office for “Icon of the Seas”.

‘Celebrity Solstice’ (122,000 gt, 2,850 passengers) dwarfed ‘Oasis of the Seas’ (225,000 gt, 5,400 passengers).  Solstice is hardly a small ship!
