Fishing vessels and the Small Vessel General Permit

Do you own a fishing vessel and are you operating in US waters? Then you have to meet the regulations of the Small Vessel General Permit (sVGP). The sVGP indicates that all commercial fishing vessels have to sail with Environmentally Acceptable Lubricants (EALs) or have to avoid an oil-to-water interface. In this blog we give tips about which sealing solutions are in compliance with the sVGP and how they deliver you Peace of Mind!

sVGP: a recap

sVGP controls incidental discharges for vessels that are less than 79 feet (24 metres), and commercial fishing vessels. The term ‘incidental discharges’ includes a range of waste water discharges from vessels during normal operations. Examples are ballast water and bilge water.

sVGP compliance with the use of EALs

To make your fishing vessel sVGP compliant, you can apply our Supreme Standard® stern tube seal. This sealing solution works with EALs and can be delivered as an aft and forward seal. If you want to sail with EALs, we suggest this stern tube seal with the addition of several customised options, such as an Hard Metal Layer and net cutters.

sVGP compliance with the use of mineral oils

However, if you don’t want to sail with EALs, we also offer the Supreme Ventus®. This air-type seal is in compliance with the sVGP, works with mineral oils and guarantees zero emissions of oil. Another factor that is convenient for fishing vessels, is the pressure compensation for every draught. Sometimes a fishing vessel has more fish on board which makes the ship heavier. This results in sailing deeper and the Supreme Ventus stern tube seal is applicable to all types of draughts.

Our advice: The Supreme Ventus seal with advanced options

For fishing vessels we recommend using this sealing solution with the addition of the following options:

To lengthen the lifetime of the liner, we advise adding a Hard Metal Layer (HML) to the seal. This HML (picture 1, position 7) is applied to the liner using HVOF spraying. Under strictly controlled production conditions, the HML is formed with a high adhesive strength and a porosity of less than 1%, and prevents crevice corrosion which can occur on ceramic layers.
