Boards of Directors and Committees

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:

Designing Ships for Greater Efficiency

  • 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.

Increasing Efficiency Through Ship Operations and Maintenance

  • 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.

Minimize Fuel Use and Engine Emissions

  • 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.

Implementing Other Energy-Saving Initiatives

  • 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.

Minimizing Engine Emissions

  • Use Cold Ironing or Plug-In while in port.

  • Install Advanced Air Quality Systems (AAQS).

  • Use alternative fuels like Liquefied Natural Gas (LNG).
