Wärtsilä & Carnival join forces in fleet decarbonisation programme

by

Marine energy tech group Wärtsilä is to deliver its new Decarbonisation Modelling Service to cruise company Carnival to reduce greenhouse gas emissions across its fleet.

Initially tasked with establishing an optimal decarbonisation path for the cruise ship ‘Regal Princess’, the project will expand to model solutions which could be applied to the entire Carnival fleet. The contract was signed in December 2021 and the project commenced in February 2022.

Under the fleet decarbonisation programme, a digital model of ‘Regal Princess’ will be created by combining operational data from several different sources. Modelling capabilities and machine-learning algorithms developed by Wärtsilä will deliver a detailed analysis of vessel operational data.

“At Carnival Corporation we are totally committed to decarbonising our operations,” says Chris Millman, Vice President, Corporate Marine Technology, Carnival Corporation. “By working closely with Wärtsilä, a company with a depth of experience and expertise, we can establish a model that will allow us to get it right first time.”

“We are delighted to work with Carnival Corporation on this important project. The complexity of current and forthcoming environmental regulations requires a methodical, systematic approach. The Decarbonisation Modelling Service is the most effective means for assessing and assuring the performance of investments aimed at meeting greenhouse gas emission reduction targets,” says Giulio Tirelli, Director, Business Development, Wärtsilä Marine Power.

There are multiple ways for ship owners and operators to comply with the International Maritime Organisation’s upcoming Energy Efficiency for Existing Ships Index (EEXI) and the Carbon Intensity Indicator (CII). Wärtsilä’s Decarbonisation Modelling Service intends to tackle this challenge by combining data-driven assessments with expert insight – enabling operators to minimise environmental impact with cost-effective investments.
