Each of the Star Cruises "Global-Class" vessels have three "Azipod XO" thrusters. All ships have installed ABB's "Intelligent Maneuvering Interface" and the "OCTOPUS" software optimizing fuel consumption and energy management. All these ships were constructed by the German shipbuilder MV Werften. Currently, almost 2/3 of all large-sized cruise vessels, icebreaking ships, and high ice-class cargo ships are with Azipod propulsion. 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).

These filter out unwanted harmonics generated by frequency converters and other HV components. The tunnel thrusters, both forward and aft, stabilizers, machinery loads, galleys, the numerous lighting and hotel loads, ensure that there is a significant demand for power at any given time. The AIDAprima ship's first successful test run for LNG supply was in Hamburg Germany on May 7, 2016. While berthed, the ship was successfully provided with LNG at all the itinerary's ports of call (Hamburg, Rotterdam, Le Havre, Southampton, Zeebrugge). There’s also a hidden advantage that those new to cruising probably never consider. You can purchase a cabin that’s near the engine room for an outstanding price, with the option to upgrade.

The efficiency of Azipod propulsion systems also translates into quieter and more comfortable cruises for passengers, as vibrations and noise levels are minimized. In summary, gas turbine propulsion systems provide cruise ships with impressive power and maneuverability. As cruise ship technology continues to evolve, gas turbine propulsion systems will play an important role in shaping the future of the industry. However, it’s worth noting that gas turbine propulsion systems do have some drawbacks.

Emergency Generators

Waste heat from the cruise ship’s engines is extracted by a series of heat exchangers located on the exhaust path after the turbochargers en-route to the scrubber. Typically, exhaust gas is approx 350°C, but it’s cooled continuously by heat extraction to approx 30°C when it emerges from the funnel. The largest ships, like the Oasis class from Royal Caribbean, contain six engines.

Moving the ship through the water takes up the vast majority of a ship's need for power -- somewhere in the vicinity of 85 percent of the power a diesel electric plant produces goes to the propeller. The rest goes toward keeping the lights on and the passengers and crew comfortable. Usually, ships are powered by four or five generator sets (medium-speed, 500 revolutions per minute), fueled by diesel and creating 8-10 MW energy each. The power density of marine diesel medium-speed engine is 80 kilowatts per cubic meter.

Diesel-Electric Propulsion

The first three Azipod units were of so-called "pushing" type in which the propeller is mounted behind the gondola. In the subsequent installations, ABB adopted the more efficient "pulling" configuration similar to propeller-driven airplanes. Staying in one of these cabins means that you will likely be exposed to plenty of noise and vibrations from the engine. You’re also likely to experience noise from the crew as they go to and from work throughout the day and night. If you were to place a cruise ship motor right out in the open and crank it up, you would get an ungodly level of noise.

It is  especially applied in many cruise destinations having smaller ports and limited tug assistance. ®A damper winding is an extra winding in the rotor provided in order for it to start as an induction motor. Once it starts and the speed nears synchronous speed, DC excitation is supplied and magnetic locking takes place.

How Do Cruise Ships Work?

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. The MAN Energy Solutions service brand not only provides 24/7 service across the globe, we are also your go-to for retrofit and upgrade solutions. Our digital updates enhance your operation, enabling remote monitoring and automated control.

If the captain feels the cruise ship will not be able to function, they will consider other options. In newer cruise ships, engines are found on the lower decks toward the aft. They are not completely to the back of the boat but are found in the mid-aft.

The generators can operate critical navigation systems, emergency lights, and other vital equipment. While connected to a generator, the engines can run at their most efficient settings regardless of the travel speed. Whether the ship is sailing at 10 or 20 knots, the engines can operate a peak efficiency. The electricity produced by the engine is used to power the ship’s propellers. We’ll cover some of the most popular technologies used by cruise ships.

There is plenty to do onboard, and if you enjoy the social scene, you may not spend much time inside the cabin other than to sleep. They can be felt in the surrounding areas, including cabins that are adjacent to them. It may cause coat hangers to rattle or other items in the cabin to shift, which may disturb your rest. If you are in the engine room while the engine is running, it will still be very loud regardless of what noise-reducing technology is used. To put it in perspective, those who enter the room are required to wear hearing protection.

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 April 2016 MSC Cruises announced its contract with STX France for up to four LNG-powered ships with GT over 200,000 tons each. The new MSC ships have 5400 passengers capacity at double occupancy each.

It is solvable by the use of either an external prime mover or a damper winding. An external prime-mover rotates the rotor to a speed close to synchronous speed after which DC is available for magnetic locking. The lighter weight, even weight distribution and compactness of DE drives also contribute in the ease of control. The other lower voltage ship loads are also supplied from the HV busbar through step-down transformers thus eliminating the need for additional gensets and reducing costs. The variable speed and torque requirements for the PEMs are handled by the convertors which convert fixed voltage and frequency to variable voltage and frequency for propulsion needs.
