Portuguese engineering services company TecnoVeritas is carrying out the environmental modernisation of Ponant’s Le Lyrial, in the latest of a series of upgrades to the cruise line’s ships.

TecnoVeritas and Ponant signed a contract in January 2022 to upgrade the cruise line’s four Boreal class expedition vessels to comply with the implementation of the International Maritime Organization’s Tier III regulations. Le Lyrial is the third vessel to be upgraded, following sister ships Le Boreal and Le Austral.

For Le Lyrial’s upgrade, TecnoVeritas is designing a selective catalytic reduction system after scanning the Boreal-class vessel in the Canary Islands. Engineering work has been carried out by TecnoVeritas prior in advance of the work onboard the ship, including exhaust gas flow simulations, electrical and control system design, mechanical design, naval architecture and classification approvals.

The customised system will be installed alongside onboard and remote emissions monitoring using BOEM, a cloud-based software developed by TecnoVeritas. A feedback control system using nitrogen oxide-type approved sensors from Danfoss will also be installed to minimise nitrogen oxide emissions and the use of urea and ammonia slip.

The system installed by TecnoVeritas will reduce the emissions of nitrogen oxides by over 80 per cent and allow the vessel to comply with the TIER III regulations.
