Monna Lisa Vessel to Cut Carbon Dioxide and VOC Emissions Using International Coatings

International, AkzoNobel’s marine coatings brand has  announced that a new cable-laying vessel, the Monna Lisa, owned by Prysmian, is to be coated in the Intergard 7500 primer and Intersmooth 7465Si antifouling solution.

This decision is estimated to reduce the vessel’s carbon emissions (CO₂) by 672 tons¹  over the dry docking period and lower Volatile Organic Compounds (VOC) by more than 11 tons  during construction.²

By utilizing Intergard 7500, a high solids universal primer solution, the shipyard can reduce VOC emissions during application and significantly decrease packaging by eliminating over 1,000 waste tins.

Intergard 7500, an aluminium containing pure epoxy product, offers superior corrosion protection and abrasion resistance, leading to significant maintenance cost savings for shipowners compared to other modified epoxy universal primers, especially when applied during newbuilding.

Intersmooth 74765Si, the chosen fouling control solution, is a low friction self polishing copolymer antifouling, which will keep a smooth clean hull in operation for the owner; minimizing fuel consumption and associated CO₂ emissions.


Shipowners are facing increasing regulatory pressures to reduce lifecycle greenhouse gas emissions, with the International Maritime Organization (IMO) announcing new carbon targets for the fleet last year.³

International and the owner reviewed different coating options and scenarios using the company’s Intertrac®Vision prediction tool to optimize and select the best scheme to deliver the optimal economic solution while maximizing the sustainability benefits. 

Prysmian states that the decision to choose both coatings for the vessel was to help meet its sustainability commitments during construction and in operation.

The Monna Lisa will be the second new-build vessel owned by Prysmian that will be applied by coatings from International, further reinforcing the partnership between the two companies and with the shipbuilder, Vard Group.

Construction of the Monna Lisa is expected to be completed and enter into service at the beginning of 2025.

^[1]This figure was calculated by comparing the performance of the Intersmooth 7465Si with a market average self polishing copolymer. It assumes that the vessel is 28% active and travels at an average speed of six knots, the fuel price of $872/t in Rotterdam (shipandbunke.com, 19th Feb 2024, MGO), assumes a five-year docking interval, and a fuel consumption for propulsion of 10 tonnes per day.
^[2]This figure was calculated using International Marine Coatings internal data, comparing the Intergard 7500 solution against previous products used in the shipyard. It found that the Intergard 7500 produced 10.7 tonnes less of VOC in total over a five-year docking period.
