The minerals added to the desalinated water are for flavour, while chlorine is a cleaning agent which will kill any unwanted bacteria. Don’t worry, it won’t taste like pool water, it’s a much lower amount – the same that would be in typical tap water. Steam evaporation systems can only be turned on when the ship is at least four nautical miles from shore, and reverse osmosis plants need a minimum depth of 50 meters to operate.
Desalination Process on Board
Evaporators use waste heat captured from the engines and exhaust gases to boil seawater and condense the steam, removing salt and impurities. Reverse osmosis systems use high-pressure to filter seawater through semipermeable membranes, producing fresh water. Lastly, cruise ships can also take on freshwater supplies when they dock at ports of call. One common type of onboard water production system is the water treatment plant.
Maiden Voyage
Some cruise lines do this automatically, while others require passengers to request refills. Either way, once the ship reaches its final destination, the water supply is replenished again. Bunkering is the term used for storing water on board before the trip begins.

They have taken the initiative to produce the majority of the clean water they use, producing over 90% of what is consumed by private destinations and operating each vessel. Fresh water tanks, or bunkers, would sit in pairs along a ship’s hull length. Each couple of tanks would be filled simultaneously to maintain the ship’s ballast and stability.
By utilizing a combination of these water sources, cruise ships can maintain a consistent and abundant water supply for their passengers and crew members. These sources undergo rigorous testing and treatment processes to ensure that the water meets the highest standards of safety and quality. These water storage and treatment systems work together to maintain the availability and quality of drinking water on cruise ships. Rigorous maintenance and testing regimens are followed to ensure the systems are functioning optimally and that the water supplied to passengers and crew is safe for consumption. Cruise ships utilize a combination of methods to obtain fresh water, including shore connections, reverse osmosis desalination, and onboard water production systems. Reverse osmosis desalination is a highly efficient process that removes salt and impurities from seawater, producing large quantities of fresh water for onboard use.
After all, providing clean and safe drinking water is essential for the health and well-being of all passengers and crew members on board. Draining the pools at night allows for cleaning, inspection, and maintenance of the pool structure, filtration, and water treatment systems. It ensures water quality and safety for passengers and allows for any necessary repairs before refilling the pool. One of the most frequently asked questions is whether tap water on a cruise ship is safe to drink.
It is because most modern cruise liners have two separate engine compartments, viz. This arrangement is given keeping in mind redundancy in case of emergency situations such as fire and flooding. It then gets released into the oceans after it has been rendered safe, which must be done at a safe distance from land as dictated by the International Maritime Organization. Yes, drinks served on ice are perfectly fine during any type of voyage. Aeration is when the water that comes out of the sink faucets and showerheads are driven by condensed air. This air gives appropriate pressure to the appliances while using less water.

Therefore, CO2 addition becomes necessary to bring down the pH within control limits. She has worked in the cruise industry since 2015 and has taken over 30 cruises. Now, she helps over 1 million people per month to plan their perfect cruise holidays.
Can I bring bottled water on a cruise or bring some onboard from ports?
The float out is typically undertaken along with a ceremony and while the ship is unfinished. Strictly Necessary Cookie should be enabled at all times so that we can save your preferences for cookie settings. Our water conservation extends to our private island destination, Perfect Day at CocoCay in The Bahamas. With so many things to do and see on board, a day spent at sea can be one of the most memorable.
Cruise ships are continuously investing in new technologies and practices to reduce water usage and minimize environmental impact. This includes the use of water-saving fixtures, such as low-flow faucets and showerheads, as well as implementing water recycling and reclamation systems. All lines will either provide distilled water in your cabin or allow you to bring it with you in your carry-on luggage. Mainstream lines are likely to charge you for providing distilled water, while upscale and luxury lines will typically provide it at no cost. Your travel agent or the customer service department for your cruise line can help you determine the procedure and/or cost of obtaining it onboard. You might be referred to a special needs department, and there might be a special request form to be submitted, often as early as 60 days prior to sailing.
The most popular method is steam desalination, since it yields a large amount of clean drinking water. To find out more about how cruise ships obtain fresh water, continue reading. Yes, desalinated seawater is safe for human consumption, as long as it has been properly purified and treated to remove any impurities or contaminants. Yes, many cruise ships use freshwater for swimming pools and hot tubs, as well as for other recreational amenities on board. The potable water hoses from the shore terminal or water tankers are connected to the ship’s potable water bunker manifold.
If you want to bring your own bottle, make sure it’s properly labeled. Otherwise, you may get charged an exorbitant amount just for having something cool to sip on board. The difference between the two types of water has more to do with the quality than anything else.
Therefore, maintaining a stable and reliable water supply is essential for the smooth operation of the ship and the comfort of all onboard. Now that we understand the crucial need for drinking water on cruise ships and the magnitude of the demand, let’s explore the various methods that are employed to obtain this vital resource. Rainwater harvesting is another technique used by some cruise ships to supplement their freshwater supply. Shore connections are often used when the cruise ship is docked at a port. The ship can connect to the local water supply to replenish its fresh water tanks.
Some cruise lines use a desalination process to make ocean water safe for swimming in their pools, while others may use a combination of ocean water and freshwater to maintain pool levels. This allows passengers to enjoy the experience of swimming in the ocean while on board. The process of reverse osmosis involves forcing seawater through a semi-permeable membrane at high pressure. This membrane has extremely tiny pores that are capable of trapping salt molecules and other contaminants, allowing only pure water molecules to pass through. As a result, the salt is separated from the water, and the fresh water is collected and stored for use onboard the ship.
This is no mean feat for a cruise ship that once complete has a gross tonnage of 236,857. In the video below you can see the unfinished Royal Caribbean Wonder of the Seas, the world’s largest cruise ship being maneuvered by tug boats in the shipyards equipping put basin. The ship must be built in a dry dock, which is a large basin that can be filled with water when docks valves are opened. Once the ship is almost complete, the dry dock is flooded with seawater, and the ship floats of its own accord. Ways of conserving energy on Royal Caribbean ships range from LED and fluorescent lights to energy- and water-efficient laundry equipment.
If you’re planning to drink ocean water while cruising, make sure that you bring along plenty of bottles. That should be no problem, as some of the high-end ships have enough capacity to produce 42,000 gallons of water per day. Steam from cooling the ship’s engines, kitchens, and other facilities plus the water produced by air conditioners are all collected and siphoned into a storage tank where they will be cleaned and reused. As previously mentioned the stored freshwater onboard will run out quite quickly unless there was a way to continuously acquire it during the voyage. The weight of the water starts to float the cruise ship off its blocks and it’s gently pushed out into the open water. After its maiden voyage, a cruise ship will enter regular service and will sail to various destinations around the world.
