GHG emissions reduction measures. Every aspect of a ship’s operation will be under increased scrutiny as owners and op-
erators seek to reduce their vessels’ emissions before the deadline. Obvious strategies
such as smart engines, slow steaming, and cutting-edge fuels will all play their part and
increase performance from both a regulatory and competitive standpoint. Operators
need to also look to other technical opportunities to reduce emissions, such as maxim-
ised hull and propellor performance.
Achieving lower fuel consumption by investing in a smooth hull already makes sound
business sense and will now be amplified with additional gains to the EEXI and CII rating.
World-leading supplier of trusted hull performance coatings Hempel has developed the
Hempaguard range, a range of biofouling resistant and low-friction hull coating systems that
deliver the lowest hull friction, both when exiting the dock and during the full dry dock cycle.
The Hempaguard X7 solution provides a 6 per cent out-of-dock power reduction, which
is an immediate EEXI improvement while guaranteeing a maximum 1.4 per cent speed
loss on a 60-month service interval on most trades, which translates into a significant
CII improvement compared with other coatings available on the market. Since it was
introduced in the market in 2013, Hempel’s Hempaguard X7 has been applied to more
than 2,000 vessels, enabling them to collectively reduce their fuel consumption by 7.6
million tons. This translates into lowering fuel costs by at least USD 2.6 billion and CO2
emissions by 23.5million tons.
Hempel’s Hempaguard MaX three-layer system, which was launched in 2019, builds
further on this solution and has been designed to dry quickly, saving on average up to
two days’ application time in dry dock. Additionally, Hempaguard MaX takes out of dock ISO 19030 quality digital performance monitoring systems
