The new cruise ship Carnival Horizon shares many of the same features as first-in-class Carnival Vista but it has two key elements that distinguish it from its sister.

Carnival Cruise Lines’ 133,500 gt Vista-class ship, which is being built by Fincantieri, is due for delivery in March this year. The focus on energy efficiency found in sister ship Carnival Vista – delivered in 2016 – has been even further boosted on Carnival Horizon.

An example is how the passenger lifts, manufactured by Schindler, are managed. This is a key distinguishing element from the first-in-class ship, as software is used to decrease energy consumption and increase the lifts’ efficiency. Not only is the system new to the Vista class, but it is the first time that it has been used on a ship.

This is significant, as Fincantieri project manager for the ship, Marco Lunardi, told Passenger Ship Technology. “We paid a lot of attention to the efficiency and environmental aspects of the lifts,” he said. “Passengers will spend less time waiting for the lift and the traffic is managed in a more efficient way to reduce the energy consumption of the lifts.”

This has been achieved by collecting destination information from passengers before they enter the lifts via a touch screen. This advance information is processed by software created especially for the lifts that combines all the passenger selection information and optimise lift availability according to the requests. Mr Lunardi said that this gave an average reduction of 30% waiting time at peak times.

The other main difference between Carnival Horizon and Carnival Vista relates to hull coatings – the former uses Hempel’s silicone hull coating, which uses a combination of hydrogel and silicone technology to combat fouling. A hydro gel microlayer prevents fouling organisms firmly adhering while the silicone polymers facilitate self-cleaning. This allows a longer period between drydock, Mr Lunardi said, because silicone paint can last more than five years.

Carnival Vista uses a “traditional” Hempel self-polishing antifouling tin-free coating. The principle on which the traditional self-polishing antifouling paint works is chemical, while the silicone one is mechanical, which means that it is a more environmentally friendly process.

A new hull

Apart from these aspects, Carnival Horizon shares technical innovations with Carnival Vista. One aspect that Mr Lunardi particularly drew attention to was the Vista-class hull. “It was very challenging to find the right hull lines,” he explained. The main reason for this was the hull had to optimised for two design points: its service speed of 18 knots and a maximum speed of 22.6 knots.

Mr Lunardi continued “This was really challenging in terms of testing and finding the right shape of the bulb and involved an external consultancy to help with knowledge.”

Extensive use of CFD calculations and in-tank model testing were deployed. “We fine-tuned the solution through several adjustments. We had to make sure that the hull lines met both service speed and maximum speed, so we needed to find the right compromise between different configurations.”

This led to a “different” and “new” hull shape compared to the rest of Carnival Cruise Lines’ fleet. In order to optimise it to meet the speed range, the bulb is more narrow than usual, compared with the usual cruise ship bulb.

An engine configuration was chosen to benefit the hull optimisation on Carnival Horizon. It consists of five MAN Diesel & Turbo engines, with two engines providing 16.8 MW of power each plus three smaller engines rated at 9.6 MW each. The two engines are type 14V48/60CR and the three are type 8L48/60CR. They are placed in the aft third of the vessel.

“They are the right size to manage the vessel in different conditions and can be used separately or in combination,” said Mr Lunardi, adding that this arrangement adds redundancy and allows the operator to meet safe return to port requirements.

Boosting energy efficiency

Energy efficiency is boosted by a steam turbine that recovers energy from the exhaust gas boilers, which would otherwise be lost. It is placed between the engines and generates 1.35 MW of power for use wherever needed, such as to boost hotel power. Fincantieri created and built the steam turbine, which has previously only been used on Vista-class ships within Carnival Cruise Lines’ fleet.

Propulsion is diesel-electric and ABB’s Azipod units are used, each absorbing 16.5 MW, bypassing the need for a propeller shaft. “They make it much easier to manoeuvre in bad weather and in windy conditions because using pods means that there is more efficient control,” Mr Lunardi said.

Another benefit is that there is more space inside the ship because the Azipods’ electric motors are not inside the ship.

Three scrubbers are used, with two for the two big engines and one allocated to one of the three smaller engines. They were developed by Ecospray Technologies and there were some challenges to overcome when it came to installing them, Mr Lunardi said. “The design of the scrubber was developed at the same time as the design of the vessel [and] the big challenge was to find a feasible coordination in a very narrow space,” he said.

“The technical solution was fine-tuned but there were a lot of adjustments and we created a dedicated team especially to work with Carnival on the scrubber.”

Particular attention was paid to the advanced wastewater treatment system (supplied by Scanship), which collects and treats grey and black water.

Fancoils and LED lighting are used throughout Carnival Horizon in order to save energy.

Like its sister ship, there is an emphasis on entertainment. To this end, features include an Imax 3D cinema and a brewery with onboard craft beer production. An impressive 63% of cabins are fitted with balconies.

Galveston Continues Expansion of Cruise Products

The Liberty of the Seas sails year-round from Galveston

For the Port of Galveston, the major news for 2018 is the continued expansion of cruise products and related services available, according to Interim Port Director Peter Simons.

Carnival Cruise Line is moving the Carnival Vista to Galveston later in the year replacing the Breeze. The Vista will sail alongside the Liberty and the Freedom.

“To accommodate the Vista we are in the process of doing some infrastructure upgrades in Cruise Terminal No. 1,” said Simons.

Last fall, the port also welcomed the Vision of the Seas, and Simons explained that while she was originally intended to be a seasonal product, she is replacing the Enchantment of the Seas on a year-round basis.

“We will have three Carnival and two Royal Caribbean ships year-round, and Disney seasonally from October to January,” he added.

The current scheduling has two ships in port on Saturdays, two on Sundays, one each on Mondays and Thursdays, and Disney on Fridays.

Terminal Expansion

“We have completed the expansion of Cruise Terminal No. 2, and when we did the design for that, we planned for larger ships and more passengers. Both of our terminals are able to handle bigger ships and more capacity,” he said.

“What we are doing though on the channel side is adding mooring structures to accommodate the longer Carnival Vista, and we are also finishing a mooring improvement project at Terminal No. 2 that will enable us to handle even larger ships in the future. We are upgrading the main mooring to be 200-ton bollards – the longer dock will also allow us easier access to the loading doors.

“We are also in the conceptual stage, looking at the designs and options for a third cruise terminal. There is definitely demand to sail from Galveston on weekends and we want to be able to accommodate what we see as future growth in that market.”

Simons said the port is talking to cruise lines about how to fund the new terminal. He said the port’s options were either bank financing or teaming up with a cruise line.

Meanwhile, he is also looking at how to provide the next generation of ships with LNG.

Team Effort

At press time, Galveston projected just short of 1.9 million passengers embarking and disembarking on some 258 sailings for 2017, up from 1.7 million passengers for 2016. For this year, the forecast is for 308 sailings and more than 2 million passengers, according to Simons.

“We see a lot of people coming down a couple of days early for special events, so there is a fair amount of extra local spending in connection with the cruise traffic. The vast majority of the passengers are drive-ups regionally and usually from the lower Midwest, but even as far north as Illinois and South Dakota. The fly-ins are typically from the West Coast.

“There is also a wide variety of things to do both on Galveston Island and in the vicinity that we are working with the cruise lines on for pre- and post-stays,” he added.

Simons, who joined the port in 2012 and was director of operations before being named interim port director, credited the port staff, the longshoremen and the stevedores for Galveston’s growing cruise traffic. He said it was a team effort with very attentive and hard-working people, making the cruise lines feel comfortable here and helping to grow their business.

Next Vista-class ship to be named Carnival Panorama

Carnival Cruise Line’s new Vista-class ship debuting in November 2019 will be named the Carnival Panorama.
Vista-class ships are the largest constructed for the line and hold 3,954 passengers; the Panorama’s sister ships are the Carnival Vista and the Carnival Horizon, which is set to make its debut in April.

The Panorama will feature a Havana section, complete with staterooms inspired by the tropics and a Cuban-themed bar and pool. It will have a Family Harbor section, as well, with larger accommodations and dedicated lounge. Also onboard will be a Cloud 9 Spa and the Ocean Plaza, a dining and entertainment venue with seating both indoors and outside.

Dining venues will also be located both inside and outside on the ship. The Panorama will have venues like the Fahrenheit 555 steakhouse, Liberty Bar and Bonsai Sushi.

As far as entertainment, the ship will feature the Skyride, a bike-ride-in-the-sky attraction; a WaterWorks aqua park; and a SportSquare recreation area.

“Carnival Panorama is the perfect name to reflect the design inspiration of our Vista-class ships providing more venues and opportunities to connect with the sea,” Carnival Cruise Line president Christine Duffy said. “Carnival Panorama will offer a wide variety of fun indoor and outdoor experiences along with exciting one-of-a-kind features that will provide our guests with a lifetime of wonderful vacation memories.”

Carnival said the Panorama’s homeport, itineraries and new features will be announced at a later date.
