Water quality plays a crucial role in vessel maintenance, yet often receives inadequate attention within the marine industry. 

Achieving high quality freshwater is essential, not only for ensuring the health and safety of all onboard but also for the optimal performance of the vessel’s systems.


The Importance of Vessel Water Quality

water quality is vital for a secure and pleasant  journey, influencing various aspects from drinking and culinary activities to bathing and sanitation. Moreover, the quality of water significantly influences the performance of the vessel’s equipment and devices. Guaranteeing that the water onboard meets high standards not only ensures comfort but is also essential for safety and effectiveness.


Compliance with WHO Guide to Ship Sanitation

Adhering to WHO standards is essential. These globally recognized benchmarks guarantee that water quality satisfies precise safety and health requirements. Compliance is frequently mandated by port authorities and is indispensable for acquiring essential certifications such as a ship’s Certificate of Sanitation. Conforming to these standards showcases a dedication to quality and safety, vital in today’s worldwide yachting sector.


Understanding Vessel Water Systems

The vessel’s water system, comprising storage tanks, pumps, filters, and pipelines, demands diligent oversight and upkeep. A comprehensive understanding of the interplay of these elements is essential for upholding water quality.

Routine inspections and periodic water assessments are crucial in order to promptly identify and address any potential concerns.

In the case of superyachts, given their extensive scale and varied water requirements, sophisticated water treatment systems are commonplace. These systems manage substantial water quantities for diverse applications, ensuring consistently clean water quality and adherence to global standards is essential.


Water Systems Maintenance and Care

Dissolved forms of lime and other salts are present in almost all water, and limescale is the main cause of hard water. The precipitation and crystallisation of minerals occur based on the amount of lime or calcium carbonate, dissolved carbonic acid, and water temperature, resulting in deposits on surface areas. These deposits reduce heat transfer in exchangers and can significantly lower the efficiency of heating installations and cooling systems.

Pressure loss and decreased flow rates are also symptoms of limescale in a water boiler. Accumulated calcium in pipes and plumbing fittings can lead to clogs, rendering them partially or completely dysfunctional. If the water has a high mineral content, it will take less than a month for calcium deposits to accumulate in and around the pipes and plumbing fittings. Therefore, the importance of regularly cleaning plumbing fittings and other pipes cannot be overstated.

Clearvac’s freshwater services ensure all accumulated minerals and contaminants are completely eliminated. Our services are available to most vessel types in Thailand.

We ensure the delivery of clean, uncontaminated water to all facilities.
