It is no secret that the maritime industry is rapidly changing when it comes to the phrase - Biofouling Management. It used to mean that vessel owners/ managers could effectively manage their annual fuel expenditures with regular, proactive hull and propeller maintenance. Now, it is one of the most highly recommended shipping practices by the IMO and various other marine organizations due to the harmful impact that invasive aquatic species has on international marine environments around the world.
The IMO is saying that a biofouling management plan is “recommended” but for any vessel calling US ports a biofouling management plan is required since 2013 in VGP. Vessels with Bahamas flag are also required to have biofouling management plans. Today the focus on biofouling from the maritime governing bodies and countries around the globe is increasing rapidly with mandated biofouling protocols in place for vessels entering New Zealand (NZ MPI), California, and Australia who have turned this “recommendation”— into law, and just like NZ MPI, more countries/ states are in the process of implementing similar regulations sooner than later.
Furthermore, the IMO has set a goal to reduce vessels that are above 5,000 GT and trading internationally to reduce their carbon intensity of international shipping by 40% up to 2030, compared to 2008. In June 2021, during the MEPC 76, the IMO had accepted the changes in Annex VI, which is related to the prevention of air pollution from vessels, in where an Energy Efficiency Existing Ship Index (EEXI) for existing vessels has been adopted. These changes will start as of 1 January 2023. From then on, vessels will get an energy efficiency rating from A – E, where A is best.
