(HELSINKI) — The technology group Wartsila is to deliver its new Decarbonisation Modeling Service to Carnival Corp. as the cruise group aims to reduce greenhouse gas emissions across its fleet.
Initially tasked with establishing an optimal decarbonization 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 and the project commenced in February 2022.
Under the fleet decarbonization program, a digital model of Regal Princess will be created by combining operational data from several different sources. Modeling capabilities and machine-learning algorithms developed by Wartsila will deliver a detailed analysis of vessel operational data.
The model will be used to simulate the impact of several technologies. A specific focus will be given to E-start, Wartsila’s patented electric smokeless start solution, as well as the Wartsila HY hybrid power concept with energy storage. The simulations will identify the most beneficial retrofitable solution while minimizing the required installation.
“At Carnival Corp. we are totally committed to decarbonizing our operations,” said Chris Millman, vice president, Corporate Marine Technology, Carnival Corp. “A systematic, data-driven approach is essential. By working closely with Wartsila, 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 Corp. on this important project. The complexity of current and forthcoming environmental regulations requires a methodical, systematic approach. The Decarbonization Modeling Service is the most effective means for assessing and assuring the performance of investments aimed at meeting greenhouse gas emission reduction targets,” said Giulio Tirelli, director, business development, Wartsila Marine Power.
There are multiple ways for ship owners and operators to comply with the International Maritime Organization’s upcoming Energy Efficiency for Existing Ships Index (EEXI) and the Carbon Intensity Indicator (CII). This freedom increases the complexity of making the right choices. Wartsila’s Decarbonization Modeling Service tackles this challenge by combining data-driven assessments with expert insight – enabling operators to maximize environmental impact with cost-effective investments.
Decarbonization modelling is part of a suite of services to help shipowners plan their pathway to reducing emissions and complying with incoming regulations. It utilizes several advanced machine-learning algorithms, including those powering Wartsila’s CII Insight – a new set of capabilities which enable owners to forecast vessel compliance with CII and understand the impact of alternative solutions.
Regal Princess is a 1,082-foot-long, 142,000-gross-tonne cruise ship built in 2014. It has a maximum capacity of 5,600 passengers and crew. The vessel is part of Carnival Corp.’s fleet of more than 100 vessels across 10 cruise brands.
