This creates pressure/speed difference that moves it in the direction of the opposite (lower-pressure) side, creating a force at a right angle to the direction of the wind. Unlike traditional cloth sails, the rotor needs no furling (stowing), reefing (reducing sail's area) or line-tending. The rotor sail system is automated and shuts down when unfavorable changes in wind force or direction occur. The Promas Lite propulsion future clients, besides passenger ships, are marine vessels like fishing and freighter ships. The 3rd Oasis-class ship - Harmony of the Seas, is currently the most technologically advanced and energy-efficient cruise vessel ever built.

On the other hand, a surge protector does the same job but with an added advantage of protecting your devices from sudden power surges. Surge protectors are generally not allowed on cruise ships due to safety concerns. When searching for a power strip, look for one without surge protection as it will more likely be permitted on board. When looking for a power strip to use on a cruise, you’ll want to find one that is cruise-approved. Cruise lines have specific safety regulations, so it’s important to choose a power strip that meets their requirements. A cruise approved power strip is an essential accessory for you if you’re planning a cruise vacation.

In comparison to pipeline gas, LNG is superior in quality - purer, with more methane and other energy content. Its chemical structure also has a stable composition that doesn't generate unburned residues, soot or any particulates. In addition, because the fuel is so clean, on LNG-powered ships maintenance intervals are doubled (over 25,000 hours / ~10140 days), as opposed to the standard MDO-powered 12,500 hours (520 days). In November 2013, the manufacturing giant Rolls-Royce upgraded Hurtigruten's ship MS Richard With its new "Promas Lite" propulsion system (integrated propeller-rudder system). This is an older ship, and Promas Lite was the perfect choice as it is a combined "propeller-rudder" system increasing the efficiency of older passenger vessels with lesser tonnage. The upgrade significantly reduced Hurtigruten's operating costs on this vessel.
Why Shore Power Is Important to the Cruise Industry
When connected while in port, ships can turn off their engines, reducing emissions and noise pollution and protecting local environments. Battery-powered cruise ships are an eco-friendly innovation with some attractive benefits. They emit zero pollutants, making them ideal for sensitive areas like coastal waters. They’re also quieter, offering a more enjoyable experience for passengers and crew.
AIDA's LNG-powered cruise ships
Engines use diesel fuel, which, when ignited, drives the engine pistons up and down. The pistons are attached to a crankshaft, and the action of the pistons turns the crankshaft, which is attached to the propeller. The propeller moves the ship through the water at a gentle speed. Companies do have to put some effort into identifying ports, though, like Barcelona, Rotterdam, and others that are able to support the infrastructure for providing shore power to one or more vessels. Smaller ports are not yet capable of shore power connections, and may never be, but the implementation where possible is a very positive step.
Modern ships use either diesel-electric engines or gas turbines as a source of power for propulsion, and for ship's systems. Some of the larger ships depend on two power sources - one for electrical power and one for propulsion. Those who support the cruise industry point out that cruising has never been more popular. A solution is to have docked vessels plug into the port's shore power grid.

Another experiment is LED lighting, using less energy and producing less heat (thus is reduced the demand for electricity and air conditioning). Celebrity Solstice-class vessels have solar panels' field over the AquaSpa pool area. This not only provides shade for the pool area but produced by solar panels electricity is used to decrease the electricity demand from the engines. Added to the dual-fuel engines, the new technology makes Viking Grace one of the world's most environmentally-friendly passenger ships, operating with very low levels of emissions and noise. Norsepower's wind propulsion system was also installed on VIKING LINE's newest vessel (still unnamed) scheduled for delivery in 2020.
The electricity generated from the diesel-electric method can also be used onboard. It is converted to a lower voltage and directed to the cabins for passengers to use. Wartsila Marine technologies aim to optimize ship performance, but also allow to locate deviations from normal parameters of equipment and engines. This allows emerging problems and engine fault sources to be fixed before they occur. Cruise Staterooms are notorious for having only one or two power outlets in the whole cabin. This makes charging your phones, iPads, laptops, and computers a real pain!

Over the last several years Hurtigruten has worked to transform even their older ships into battery-powered and LNG powered ships that can sail in and out of Norwegian ports cleanly and silently. Due to it’s size, AIDA had to remove one of the unused water tanks on the ship, AIDAperla, the 125,000 gross ton vessel being powered by electricity. The cylindrical rotor sail has a height of 24 m (79 ft) and a diameter of 4 m (13 ft). The technology is based on the "Flettner rotor" (patented by Anton Flettner in 1922) and uses the so-called "Magnus effect" - the spinning rotor (rotating cylinder) drags airflow faster around one side.
The overarching aim is to diminish a ship’s carbon footprint both while docked — and while at sea. The Port of Seattle has two shore power connected berths at the Smith Cove Cruise Terminal at Pier 91. Additionally, a project to expand shore power to the Pier 66 cruise berth is expected to be completed and online during the 2024 cruise season.
Then Heat exchangers cool the carrier fluid to temperatures around 20 C / 68 F. Azipod marine ship propulsion is a combination of both steering and propulsion systems. Conventional marine propulsion systems use a two-stroke engine connected to a shaft, that passes through a stern tube and shaft tunnel to connect to the propeller outside the hull in the ship's aft/stern.
This also made it the world's first hybrid vessel that uses both wind power and dual-fuel (diesel-gas) engines. In May 2015, Wartsila Corporation and Carnival Corporation partnered to optimize cruise ship engine room operations of all 101 ships across the corporation's 9 brands. The deal was signed by Micky Arison (Carnival's Chairman) and Bjorn Rosengren (Wartsila's President and CEO). The plan included installing Wartsila's latest marine solutions, first tested on several Carnival Cruise Line vessels in pilot projects. The new systems and technologies included engine control and monitoring systems, safety and fuel efficiency equipment. Cruise vacations are a relaxing and enjoyable way to explore the world, but staying connected to your electronics is also necessary.
While ships are at berth, they still need energy to run lights, chill food, operate equipment, and power a myriad of other onboard services. A shore power connection allows cruise ships to plug into cleaner, landside electrical power and turn off diesel engines while at berth. As a result, each cruise ship that plugs in can reduce diesel emissions by 80% and CO2 emissions by 66% on average. The first company that fitted cruise vessels with gas turbines, was Royal Caribbean. Gas turbines are greener than diesel engines and allow ships to sail with reduced inventory and smaller maintenance crew.
This allows for quiet, smooth sailings into the gorgeous fjords of Norway. In this article, we will explore five different battery-powered cruise ships and companies that are leading the charge in green maritime transportation. The cruise industry began in 1844, when ships were propelled by steam engines, performing the driving of propellers by using steam as working fluid. The largest passenger steamship (before hitting an iceberg on April 14, 1912) was the Titanic, powered by both reciprocating engines and turbines, able to generate 50,000 horsepower (37 megawatts).
Azipod turns in all directions (360 degrees) by a rudder, providing thrust in any directions, not possible for conventional systems. ABB Azipod propulsion systems have a major impact on the vessel's operating efficiency - reducing energy consumption and bad emissions by up to 20%. All ships are supplied with emergency generators to maintain vital electrical power. Backup generators are located higher up and also outside engine room spaces to isolate them from damage or fire.
