Performance Criteria

Independent testing , and assessment of the following criteria

1. The cleaning process removes at least 90% of visible fouling2. removes 90% of material from seawater influent and 95% of

particulate material in effluent water is less than 10 micron3. Local water quality remains unaffected

4. Optional – Dissolved and particulate biocides are not elevated significantly above ambient levels during the same period.

Sustainability developmentsLife under water: By 2020, sustainably manage and protect marine and coastal ecosystems to avoid significant adverse impacts, including by strengthening their resilience, and take action for their restoration in order to achieve healthy and productive oceans

Climate change: Integrate climate change measures into national policies, strategies and planning

Decent work and economic growth: Protect labour rights and promote safe and secure working environments for all workers, including migrant workers, in particular women migrants, and those in precarious employment

Commercial: BIMCO Hull Fouling Clause for Time Charter Parties 2019

• Reliable and easy to use clauses which fit into existing time charter party scheme

• Tackles the hull fouling issues by allocating risk and responsibility in a fair and proportionate way between shipowner and charterer

• Capable of being applied across the board, irrespective of vessel type and trade

Our visionTo be the chosen partner trusted to provide leadership to the global shipping industry.

Our missionTo be at the forefront of global developments in shipping,

providing expert knowledge and practical advice to safeguard and add value to our members’ businesses.

Thank you!

PPG Biocide-Free Fouling Release SystemThe Environmental Benefits and how it can contribute

towards EEXI and CII requirements

• Basic principle of fouling protection is biocidal activity

preventing fouling species to settle and grow

• Self polishing antifouling introduced in 1974

• Biocidal Free solutions breakthrough in technology

PPG Biocide-Free Fouling Release System2

The technical evolution of fouling protection

The easy way to improve power and CO2 emissions

• Shifts the power curve (IMO EET cat. A) - verified with CFD (ITTC)

• Improves the EEXI and EEDI via reduced power (up to 10%)

• Improves the CII rating via reduced CO2 emissions (up to 25%)
