What is required regarding shore tie connections during cold weather?

The requirement to drain and isolate shore tie connections during cold weather is crucial for preventing damage and ensuring safety. When temperatures drop, water inside the connections can freeze, leading to potential bursting of hoses and damage to the electrical systems. Draining and isolating these connections when they are not in use prevents ice formation and maintains the integrity of the system, ensuring that it functions properly when needed.

In contrast, regularly inspecting connections may help in identifying issues but does not address the immediate concern of freezing in cold weather. Keeping them energized at all times can potentially increase the risk of overheating or electrical issues, especially in extreme conditions where no load is present. Removing them entirely would not be practical, as the connections are necessary for power and support while the vessel is in port. Therefore, isolating and draining is the best practice for safeguarding equipment in colder climates.
