Seawater desalination equipment provides a "source of life" for long-term operators at sea

2024-10-15

　　In the vast expanse of the sea, the offshore operation platform stands like an island, carrying important missions such as energy exploitation, Marine scientific research, and fishery and aquaculture。However, the special environment away from land makes the supply of fresh water an urgent problem。Seawater desalination equipment, as a key means to solve the problem of water use in offshore operations, is playing an irreplaceable role。This paper will deeply discuss the application value, technical principle and change of seawater desalination equipment in offshore operation。

　　Water challenges for offshore operations

　　The offshore operation cycle is long, and the demand for domestic water for staff, cooling water for production equipment, and direct water for some specific operations is huge。Traditional fresh water transportation is not only costly, but also greatly affected by weather and sea conditions, which is difficult to ensure a sustainable and stable water supply。Therefore, it is particularly important to achieve self-sufficiency in converting seawater into fresh water on site。

　　Overview of seawater desalination technology

　　The main desalination technologies in China include freezing method, electrodialysis method, distillation method, reverse osmosis method, etc., of which reverse osmosis method occupies most of the desalination market。LightriderShanghai water treatment CompanySeawater desalination equipment adopts reverse osmosis membrane technology，By means of a high pressure pump，Only the water molecular solvent in seawater can pass through the reverse osmosis membrane，Ionic materials such as salt will be trapped in the membrane，In this way, it can remove unwanted components such as dissolved salts, colloids, microorganisms, and organic matter in seawater，To achieve seawater freshwater。

　　Application advantages of seawater desalination equipment in offshore operations

　　1.Independent water supply, reduce logistics costs: The offshore desalination device directly converts the surrounding abundant seawater resources into usable fresh water, greatly reducing the dependence on land fresh water supply, reducing high transportation costs and logistics risks。

　　2.Flexibility and reliability: Modern desalination equipment is compact and adaptable, and can be customized to the specific conditions and water needs of the operating platform, ensuring stable operation in harsh sea conditions。

　　3.Environmentally friendly and promotes sustainable development: Compared with traditional long-distance transport of fresh water from land, on-site desalination reduces carbon emissions, conforms to the concept of Marine environmental protection, and supports green Marine operations。

　　4.Integrated intelligent management: integrated remote monitoring, automatic adjustment and other functions, through the Internet of Things technology to achieve real-time monitoring of equipment operating status and fault warning, improve operation and maintenance efficiency and safety。

　　In the face of the unique challenges of offshore operations, desalination equipment has become an indispensable lifeline, not only to solve basic water needs, but also to promote offshore operations in the direction of autonomous, efficient and green。With the continuous progress of technology and the further reduction of costs, seawater desalination will show its unique value in more offshore application scenarios, providing a strong guarantee for human development and utilization of Marine resources。
