There are no facilities for deballasting.
Ballast water exchange in deep water. Entries in bridge and engine room logbooks showing geographical co-ordinates, amount replaced and what percentage of total ballast it represents.
Alternatives to En Route Management Procedures
In-tank treatment prior to discharge. Addition of 100.0 grams of powdered sodium hypochlorite, or 14 grams of powdered calcium hypochlorite per ton of ballast water, ensuring thorough mixing, and the waiting 24 hours before deballasting.
Ballast water Report
As per Chilean Water Ballast Regulations all vessels entering Chilean Waters must change water ballast at least 12.0 nm off the Chilean coast. This procedure must be duly noted in the logbook.
In case the Port Authority detects any abnormal situation, and you can not prove renewal of water has been done, the vessel will have to sail out 12.0 nm to change ballast, prior being allowed to enter the port again. Also upon arrival you will have to complete a Water Ballast reporting Form, indicating place/Volume/Date/Hour of deballasting.
It is also important to mention that no contaminating products can be discharged in Chilean waters like chemical- or tank’s cleaning remains.
