We are continually investing in a broad range of voluntary energy reduction initiatives that meet or surpass the requirements of current laws and regulations.
We are continually investing in a broad range of voluntary energy reduction initiatives that meet or surpass the requirements of current laws and regulations. Reducing fuel and driving energy efficiency requires multimillion-dollar investments and a multi- pronged strategy. Below is a list of some of the initiatives we are currently working on:
Optimize hull design to minimize drag.
Select fuel-efficient combustion equipment.
Install equipment such as steam turbines to use waste heat.
Install energy-efficient onboard equipment, including lighting.
Optimize diesel generator use at sea and in port.
Manage use of evaporators and reverse osmosis plants.
Use LED lighting.
Utilize sophisticated control systems for heating ventilation and air-conditioning (HVAC).
Monitor and improve chiller performance.
Apply highly efficient anti-fouling marine hull coatings.
Use state-of-the-art underwater robots that help us to clean propellers and hulls regularly
and collect the fouling removed.
Introduce detailed energy monitoring systems to target improved energy consumption.
Increase use of waste heat from engine exhaust for fresh water production, chilled water,
and steam generation.
Use on-demand methodology for galley ventilation control.
Examine ways to increase engine efficiency through fuel treatment systems which improve combustion and reduce fuel consumption.
Optimize the use of diesel generators on board to improve efficiency.
Use waste heat generated by the ships’ engines to make steam instead of relying on the ships’ boilers.
Reduce the power required by engine room ventilation fans through use of variable-frequency fan-drive motors and related pressure and temperature control systems.
Design more fuel-efficient itineraries.
Use voyage optimization tools.
Increase energy use awareness through education and training of guests and crew.
Develop our ability to use alternative fuels.
Research and develop emissions-reduction technologies such as energy storage systems and fuel cells.
Incorporate an innovative “Air Lubrication System” which creates bubbles between the ship’s hull and water to reduce friction.
Use Cold Ironing or Plug-In while in port.
Install Advanced Air Quality Systems (AAQS).
Use alternative fuels like Liquefied Natural Gas (LNG).
