One of the largest cruise ships in 1985 was the 46,000-ton Carnival Holiday. Ten years ago, the biggest, the Queen Mary 2, was three times as large. Today’s record holders are two 225,000-ton ships whose displacement, a measure of a ship’s weight, is about the same as that of a Nimitz-class aircraft carrier.
Cruise ships keep getting bigger, and more popular. The Cruise Lines International Association said that last year its North American members carried about 17 million passengers, up from 7 million in 2000.
But the expansion in ship size is worrying safety experts, lawmakers and regulators, who are pushing for more accountability, saying the supersize craze is fraught with potential peril for passengers and crew.
“Cruise ships operate in a void from the standpoint of oversight and enforcement,” said James E. Hall, a safety-management consultant and the chairman of the National Transportation Safety Board between 1994 and 2001. “The industry has been very fortunate until now.”

The perils were most visible last year when the Costa Concordia, owned by Miami-based Carnival, capsized off Italy. The accident killed 32 people and revealed fatal lapses in safety and emergency procedures.
In February, a fire crippled the Carnival Triumph, stranding thousands without power for four days in the Gulf of Mexico until the ship was towed to shore. Another blaze forced Royal Caribbean’s Grandeur of the Seas to a port in the Bahamas in May.
Although most have not resulted in any casualties, the string of accidents and fires has heightened concerns about the ability of megaships to handle emergencies or large-scale evacuations at sea. Sen. Jay Rockefeller, D-W.Va., introduced legislation this summer that would strengthen federal oversight of cruise lines’ safety procedures and consumer protections.
Industry defends size
Cruise operators point out that bigger ships have more fire-safety equipment and contend they are safer. After a fire aboard the Carnival Splendor three years ago, Carnival adopted new training procedures and added safety features it says helped with the rapid detection and suppression of the fire on the Triumph.
After that fire, Carnival also announced it would spend $700 million to improve its safety operations, including $300 million on its fleet of 24 Carnival Cruise Lines ships. Carnival is the largest cruise operator, owning about half of all cruise ships worldwide.
“We have over time improved the safety of our vessels by better training and better technology and learning from incidents that have happened over the years,” said Mark Jackson, Carnival’s vice president for technical operations, who joined the company in January after 24 years with the Coast Guard.
Some experts doubt that ships can grow much larger than the current behemoths, marvels of naval engineering that combine cutting-edge technology and entertainment.
Today’s biggest ship, Royal Caribbean’s Allure of the Seas, has 2,706 rooms, 16 decks, 22 restaurants, 20 bars and 10 hot tubs, as well as a shopping mall, a casino, a water park, a half-mile track, a zip line, mini golf and Broadway-style live shows.
It can accommodate nearly 6,300 passengers and 2,394 crew members — the equivalent of a small town towering over the clear blue waters of the Caribbean Sea. It measures 1,188 feet long. Its sister ship, the Oasis of the Seas, is 2 inches shorter.
Experts point out that larger ships have larger challenges. For instance, they have fewer options in an emergency, said Michael Bruno, dean of the engineering school at the Stevens Institute of Technology in Hoboken, N.J., and former chairman of the National Research Council’s Marine Board.
“Given the size of today’s ships, any problem immediately becomes a very big problem,” he said. “I sometimes worry about the options that are available.”
A recent report by the Coast Guard on the Splendor fire revealed glaring problems with the crew’s firefighting abilities as well as failures in fire-safety equipment.
The investigation did not address the size of the ship, which carried 3,299 passengers. But it showed that big vessels can quickly become crippled by small fires that disable complex systems. No passengers were hurt, but the damage to the engine room was severe, disabling the ship’s power and forcing it to be towed to San Diego.
The investigation found a wide range of problems with the engine’s maintenance history as well as missing fire-safety records.
No fire drills had been conducted in the engine room for six months. Emergency sprinklers were turned off by mistake, then doused the wrong parts of the engine room. Believing the fire had been contained, the captain vented the engine room to clear out the smoke. He reignited the fire instead.
Operators on hot seat
These incidents have brought new attention to the behavior of cruise operators. Rear Adm. Joseph Servidio, the Coast Guard’s assistant commandant for prevention policy, said at a Senate hearing in July that the three fires, including the one aboard the Splendor, “highlight serious questions about the design, maintenance and operation of fire-safety equipment on board these vessels, as well as their companies’ safety-management cultures.”
In July, the Coast Guard said cruise ships would need to conduct periodic engine-room fire drills.
The risks of building bigger ships became apparent over a decade ago, as cruise companies pushed the limits of naval architecture. The head of the International Maritime Organization, the United Nations agency in charge of marine regulations, warned in 2000 of the growing hazards of building larger ships and called for a comprehensive review of safety rules, known as Safety of Life at Sea, or SOLAS. William O’Neil, the group’s secretary-general at the time, said the industry could not “rely on luck holding indefinitely.”
One result was a set of new global regulations in 2010 called the Safe Return to Port rules. Those require new ships to have sufficient redundant systems, including power and steerage, to allow them to return to port even in the worst emergency. Only about 10 ships built since then comply with this new rule.
“The idea is that a ship is its own best lifeboat,” said John Hicks, the vice president for global passenger ships at Lloyds Register, the largest ship-classification society. “The idea is to do everything to keep the crew and passengers on a vessel.”
Bud Darr, the senior vice president for technical and regulatory affairs at the Cruise Lines International Association, said today’s ships operated under layers of oversight.
The Coast Guard inspects each ship that calls at U.S. ports at least once a year and enforces national and international norms. Private auditors, hired by cruise operators, perform frequent safety reviews, including comprehensive annual checks that last seven to 10 days, he said, and flag countries like the Bahamas or Panama, where most cruise ships are registered, provide their own oversight.
“We are subject to very close scrutiny,” Darr said. “The standards are universal.”
But incidents like the Costa Concordia grounding have raised questions about whether evacuation regulations are still applicable in the age of megaships. Under the SOLAS regulations, for instance, passengers grouped at their muster stations must be able to evacuate on lifeboats within 30 minutes of an evacuation alarm.
The investigation into the Costa Concordia revealed that the crew and its captain failed to sound the general evacuation alarm for more than an hour after rocks had breached the hull. As a result, some lifeboats could not be lowered once the ship started to list.
After the accident, cruise operators said they would change muster procedures. Instead of holding a drill for passengers within 24 hours of departure, cruise ships said they would do so before ships leave a port.
While ships are becoming bigger, the burden on crew members is growing. The Queen Elizabeth 2, launched in 1969, had one crew member for about 1.8 passengers. On the Triumph, the ratio was one crew member for every 2.8 passengers. The issue is also complicated by language and communication problems, and a high crew turnover rate that can reach 35 percent a year.
The International Transport Workers’ Federation, which represents seafarers and crew members, has expressed concerns about the evacuation time and suggested the need to limit the number of people aboard ships, depending on where they operate and what search-and-rescue facilities are available.
“Experience has cast doubt on the adequacy of existing lifesaving appliances,” the group said in a report. “The current equipment, especially lifeboats and life rafts, has proved to be inadequate when confronted with high sea states.”
Safety rules also state that lifeboats should not carry more than 150 people. But the two largest ships, the Allure of the Seas and the Oasis of the Seas, have much bigger lifeboats, for 370 people, because of a provision of the 2010 rules that allows for exemptions if the cruise line can demonstrate an equivalent level of safety.
Those bigger lifeboats have only enough room for passengers. To evacuate the more than 2,300 crew members, the ships are equipped with inflatable rafts that would have to be entered through 59-foot evacuation chutes.
“The simple problem is they are building them too big and putting too many people aboard,” said Capt. William H. Doherty, a former safety manager for Norwegian Cruise Lines, the world’s third-largest cruise operator, and now the director of maritime relations at the Nexus Consulting Group. “My answer is they probably exceeded the point of manageability.”
He added, “The magnitude of the problem is much bigger than the cruise industry wants to acknowledge.”
