How to Choose a Desalination System for Yachts, Ships, and Offshore Platforms

When you’re sailing on a motor yacht, vessel or out on an offshore platform, it’s important that you have access to clean drinking water. That’s where it helps to have a desalination system. A desalination system is a piece of equipment which takes saltwater from the ocean and turns it into fresh, potable water. But there are so many different kinds of desalination systems on the market, how are you to know which one is right for your boat? We will consider the various marine desalination systems and look at how you can find the best for all your aquatic adventures.

Types of Desalination Systems for Offshore Applications explained.

The principal types of desalination technologies that are used mostly in the marine sector include reverse osmosis, multi-stage flash, and multi-effect distillation. Each system type has its pros and cons, so it’s important to know how each operates before deciding which one to go with.

RO is also the most common desalination system in use on yachts, ships and offshore platforms. It operates by passing seawater through a membrane to remove salt and other impurities, leaving behind fresh clean water. Reverse osmosis systems are space saving, easy to set up, and extremely low maintenance, proving a popular option for smaller craft.

Another method of desalination is the multi-stage flash distillation, which is widely employed in marine applications. Here, the seawater is heated to produce steam, but then the steam is re-liquefied and turned into water again. The multi-stage flash distillation systems require more energy than reverse osmosis system, but with more fresh water produced, this type of system are more suitable for larger vessels and offshore platforms.

Multi-effect distillation There is a third type of desalination system which is also in common use at sea. The system functions by boiling seawater at several stages to create fresh water. Multi-effect distillation machines are increasingly effective and able to generate vast amounts of fresh water but are also more complicated and expensive to buy and run.

What You Should Consider When Choosing a Desalination System for Your Boat

If you’re a boat owner looking to pick the desalination system that’s right for you, there are some key considerations to take into account. This factors the size and utility of the system,its energy efficiency and maintenance needs, and its total cost. 

How to select the correct size and capacity for your Marine Desalination System

Your desalination system will vary based on the size of your boat and the number of people onboard. It’s crucial to select a system that can create sufficient drinkable water to support the daily requirements of everyone on board for drinking, cooking and sanitation.

Things to consider when sizing your desalination system include the amount of water you typically use in 24 hours, the quality and temperature of the water you take in, and how much space you have to work with. It should also be scalable so that you have the ability to ramp up or scale down operations without hassle.

Assessing the Energy and Maintenance Costs of Desalination Plants

Naturally, energy efficiency is also a key aspect to look at when choosing a desalination unit for your boat. Search for systems that are engineered for minimal energy use, whether they are reverse osmosis systems that feature energy recovery devices or multi-effect distillation (MED) systems with heat exchangers.

Maintenance demands are another factor to consider when selecting a water desalination systems for your boat. Opt for low maintenance systems Look for systems that make it easy to maintain them as they will require less care or TLC, such as systems with automatic cleaning cycles to others that feature remote monitoring options.

Selecting an Affordable and Affordable Desalination for Your Marine Requirements 

Finally, selecting the best desalination unit for your yacht, ship or offshore platform is key to guaranteeing a good supply of clean drinking water at sea and above waterline. When choosing a system for your vessel, consider factors such as system size and capacity, energy efficiency, maintenance and overall cost.
