Carnival Cruise Line has entered an agreement with Shell for the supply of marine liquefied natural gas (LNG) to power two new cruise ships.

Expected to be launched by 2020 and 2022 respectively, the ships will be ported in North America.

Under the agreement, Shell will supply fuel through its LNG Bunker Barge (LBB) project, which is part of Shell’s strategic plan to develop a global LNG bunkering network. It aims to support growing demand for LNG as a marine fuel by enabling LNG-powered cruise lines to refuel at ports along the southern US East Coast.

Carnival Cruise Line president Christine Duffy said: “Carnival Cruise Line is strongly committed to leading the way in the implementation of technology innovations to help protect the environment and support our aggressive sustainability goals.

“Carnival Cruise Line is strongly committed to leading the way in the implementation of technology innovations to help protect the environment.”

“Our two new cruise ships entering service in 2020 and 2022 will not only be the largest and most technologically advanced in our fleet but will break extraordinary new ground as the first LNG-powered cruise ships in North America.”

Each of Carnival Cruise Line’s new ships will feature 180,000t capability and will be able to accommodate around 5,200 passengers based on double occupancy.

Carnival has also contracted Shell to supply LNG fuel to its next-generation ships, which belong to the European AIDA Cruises and Costa Cruises brands.
