Blanking of sea chests
Blanking of sea chests/plugging of intakes or overboard discharges to assist at inboard repairs is a FN Diving speciality.
This is a very cost-effective method of changing defective valves and repairing sea chests plating, while afloat during normal ship operations.

FN Diving also has extensive experience in maintaining box coolers and their anodes while afloat. In cooperation with our suppliers, we deliver a complete solution for the exchange of class approved overboard valves from their vast stock. We guarantee to get you back on schedule fast. Feel free to contact us!
Important information
When replacing a valve we require the following information:
- Sort of valve; butterfly, globe, gate, ball etc.
- Face to face dimensions.
