The first cruise ship in North America to be powered by LNG
Mardi Gras is Carnival Cruise Line’s newest and most innovative ship to date. It was named after Carnival’s first vessel of the same name, which sailed from 1972 to 1993.
The Finnish shipbuilder Meyer Turku built Mardi Gras in Turku, Finland, completing it in 2020. Mardi Gras is the largest ship in Carnival’s fleet with a gross tonnage of 180,000 and a capacity to accommodate up to 6,500 passengers and 1,750 crew members.
Mardi Gras is the first cruise ship in North America to be powered by eco-friendly Liquefied Natural Gas (LNG). Among the cleanest fuels in the world, LNG significantly reduces emissions with cleaner exhaust.
Mardi Gras has six distinct themed zones with a variety of food, beverage and entertainment options, including dining venues from Guy Fieri, Emeril Lagasse, Rudi Sodiman and the line’s Chief Fun Officer Shaquille O’Neal. One of the highlights of the ship is BOLT, the world’s first roller coaster at sea.
As part of Carnival’s highly anticipated return to guest operations, Mardi Gras began its seven-day Caribbean cruises on July 31.
Mardi Gras is equipped with Halton Marine’s products and solutions
With more than 25 years of experience in the industry, Halton Marine provides a wide range of energy-efficient HVAC products and solutions designed specifically for marine environments, where safety, robustness, and controllability play an important role. Halton Marine had the privilege to deliver its superior products and solutions, including galley hoods, canopies and dampers, to Mardi Gras.
Galley hoods for high-capacity utilization
More than 200 pieces of galley hoods and canopies were installed in galleys and restaurants of Mardi Gras, including the ship’s main galley and more than 25 restaurants on 8 decks. Halton Marine’s scope of supply included KWH and KFM galley hoods equipped with high-efficiency grease filtration. The KWH hoods are also equipped with UV-light technology that keeps the plenum and duct virtually grease-free and mitigates the cooking odour and emissions.
The KWH and KFM galley hoods are specifically designed for high-capacity utilization in demanding applications where improved hygienic conditions, safety and reliability are essential.
M.A.R.V.E.L. enables impressive energy savings in galley ventilation
The Halton Marine galley hoods installed in the Pastry, Hot Galley and Garde Manger areas of the Mardi Gras main galley are equipped with M.A.R.V.E.L. demand-based ventilation system.
Halton M.A.R.V.E.L. is the first truly intelligent, responsive, and completely flexible demand-controlled ventilation system specifically designed for Halton hoods. Halton M.A.R.V.E.L. can identify the current status of each cooking appliance in the entire galley (switched off, heating to cooking temperature, or cooking in progress) and adjust the amount of exhaust airflow and fan speed as needed for each hood. M.A.R.V.E.L. offers the lowest levels of energy consumption in galley ventilation while also improving user comfort.
Halton Marine dampers contribute to the safety and security of Mardi Gras
The safety and security of guests and crew members are paramount to Carnival Cruise Line. Mardi Gras is equipped with Halton Marine fire and gas dampers, gas-tight shut-off dampers, and flow control dampers.
Halton Marine fire and gas dampers are designed to prevent a possible progression of fire, smoke and gas via the ductwork to other areas of the cruise ship. Mardi Gras is equipped with FDB2 fire and gas dampers, the most widely sold marine damper of its kind in the world.
The HVAC system’s feature to achieve the correct balance of airflow, temperature, pressurisation and safety levels in the ductwork relies partly on the airflow management dampers, such as Halton UTG gas-tight shut-off dampers, designed specifically to be used to shut-off and balance airflow rates in high-pressure ductworks.
