The NOFI Current Buster 4 underwent a total upgrade in 2019 with the main purpose of achieving slightly higher oil collection towing speed in slightly higher waves while keeping the original storage volume and weight. Other improvements like better ability to handle debris, ability to retrieve system with both stern and front first and larger front opening during single vessel operation have been implemented. When this manual mentions the NOFI Current Buster 4 , this interprets the upgraded version unless otherwise stated.

SAFETY: Any boom handling and especially high speed operations involve heavy forces and impose a safety risk. In order to avoid personnel injuries, sound seamanship should be practised in all operations. Local safety regulations and practice must be followed.
