Hybrid Passive and Active Anti-icing Technologies for Mitigating Ice Accretion on Marine Structures

Dear Colleagues,

In cold regions, marine structures such as ships, offshore platforms, and coastal infrastructure are often exposed to ice formation and accretion, which can lead to reduced efficiency, safety risks, and even structural damage. To mitigate these issues, various anti-icing technologies have been developed, including passive and active approaches.

Passive anti-icing technologies, such as icephobic coatings and surface modifications, rely on the inherent properties of the material to prevent ice adhesion and promote ice shedding. These technologies are potentially low cost and easy to apply but may have limited effectiveness in severe icing conditions.

Active anti-icing technologies, on the other hand, actively remove or prevent ice formation through methods such as heating, de-icing fluids, and acoustic vibration. While more complex and expensive than passive approaches, active anti-icing technologies can provide greater effectiveness and control in harsh icing environments.

Recent advancements in anti-icing technologies have focused on developing hybrid approaches that combine passive and active methods to improve performance, reduce costs, and enhance safety. For example, researchers have explored the use of smart coatings that can switch between passive and active modes depending on the severity of the icing conditions. Another promising area of research is the integration of anti-icing technologies with renewable energy sources, such as solar and wind power, to reduce reliance on traditional power sources and minimize environmental impacts.

Overall, the development of effective anti-icing technologies is crucial for ensuring the safety and efficiency of marine operations in cold climate regions. By combining passive and active approaches and leveraging emerging technologies, researchers and engineers can continue to advance the field and improve the resilience of marine structures against ice accretion.

This scope of this Special Issue will serve as a forum for papers in the following concepts:

• Passive anti-icing technologies;
• Active anti-icing technologies;
• Low ice adhesion surfaces;
• Mechanics of ice;
• Atmosphere Icing;
• Sea spray icing;
• Remote sensing of ice;
• Icebreaker ships;
• Adhesion behavior of ice.
