Lifeboat question

[DisneyNurse19]

Well i would rather be in a Life raft with the crew than a Lifeboat with moaning guests

haha! It's true! Although, they probably don't want any passengers in their life raft if they can help it.

wanna get technical????


SOLAS has been revised and updated many times and now comes under the auspices of the International Maritime Organisation (IMO). It has fairly extensive rules about the all aspects of lifesaving equipment including the location, number and size of lifeboats to be carried on a ship and how quickly the passengers should be able to be evacuated from the ship. The 1983 amendments to SOLAS required all lifeboats on passenger ships to be totally or partially enclosed equipped with an engine rather than the traditional open lifeboats manual propelled by oars.

Modern passenger ships engaged on international voyages, which are not short must carry partially or totally enclosed lifeboats on each side to accommodate not less than 50% of the total number of persons on board, in other words, the two sides together must equal at least 100%. Some lifeboats can be substituted by liferafts. (emphesis mine) In addition, inflatable or rigid liferafts to accommodate at least 25% of the total number of persons on board. Sufficient lifeboats and liferafts of such capacity as to accommodate 125% of the total number of people on board.

Passenger ships on short international voyages must carry partially or totally enclosed lifeboats for at least 30% of persons on board, plus inflatable or rigid liferafts to make a total capacity of 100% with the lifeboats. In addition, they must carry inflatable or rigid lifeboats for 25% of total number of persons on board.

There are also regulations on how long the actual lifeboat embarkation should take and how long it should take to prepare and launch all the lifeboats and liferafts once the passengers have been assembled and the abandon ship signal has been given. There are also now IMO guidelines ( MSC Circ 1033 and 1283) on the total passenger ship evacuation times including assembling the passengers at their muster stations. The SAFEGUARD project is also undertaking a series of full scale passenger ship evacuation trials to provide additional data to further develop the passenger evacuation guidelines.

The recent philosophy of the passenger ship design has now returned to the idea of regarding the ship as its own best lifeboat capable of providing a “safe area” for passengers until “return to port” or adequate rescue services arrive. IMO has set out Safe Return to Port requirement in the 2009 International SOLAS treaty, which are applicable to passenger ships built on or after the 1st July 2010. These new requirement were prompted by the increasing size of passenger ships. The more passengers a vessel has the longer it takes to evacuate. The requirement defines minimum limits on how long the vessel should remain safe for evacuation. It defines threshold where ships should be able to return to port without requiring passengers to evacuate.

SOLAS definition: "Short international voyage" means an international voyage:

a.) in the course of which a ship is not more than 200 miles from a port or place in which the passengers and crew could be placed in safety, and

b.) which does not exceed 600 miles in distance between the last port of call in the country in which this voyage begins and the final port of destination,
but for the purposes of this definition, no account shall be taken of any deviation by a ship from the intended voyage due solely to the stress of weather or any other circumstances that neither the master nor the owner nor the charterer (if any) of the ship could have prevented or forestalled.

Note those that you would make alliances with and those that you would eat first.

that's why when you go back to your stateroom in an actual emergency, along with your meds you grab a bottle of hot sauce.

Very helpful post! I note that the requirements are for the total number of persons on board, not just for passengers. From this, and that lifeboats can be substituted by life rafts, it appears that a cruise line does not have to provide an enclosed lifeboat for passengers and relegate only the crew to life rafts.

So that means it's possible you could get a liferaft as opposed to a lifeboat? If so, make sure you grab sunscreen from your cabin, in addition to the warm clothes.

And is it at least air conditioned/heated?

Given the amount of power ac & heating require, my guess is that lifeboats don't have them. They're built for survival, not comfort.

No, actually two levels (the black figures show where you sit and the direction of the legs). The people on the lower level are looking at the knees of the people on the upper level. You're going to get very chummy with your lifeboat companions.

Inwas just thinking that! God forbid and there is an evacuation and you are stuck there for a day until a boat comes.

My first thought do these have tioletts?

The lifeboats? I am pretty sure they do not.

I’m sure it will be like a lot of people has to go. Once one person couldn’t hold it anymore. Than other people will join in and pee or poop their pants. It’s only so long that you can hold it.

"The SOLAS regulation on Life Saving Equipment (LSA) code 4.4.3.1

states: “No lifeboat shall be approved to accommodate more than 150 persons.” However, the regulations do actually provide procedures for using lifeboats of greater capacity providing it can be demonstrated that they have an equivalent level of safety. Schat-Harding has developed a 370-person lifeboat and davit system. The Oasis of the Seas cruise ship was the first vessel to be fitted with these new mega lifeboats.

As the size and capacity of modern cruise ship has increased there

becomes a potential problem of having sufficient space to fit the required number of lifeboats. The cruise ship Oasis of the Sea is fitted with 18 of the new mega lifeboats. A total of over 44 of the traditional 150 persons lifeboats would have to be fitted to accommodate the same number of passengers. The overall length of the Oasis of the Seas has an overall length of 360m. The typical length of a 150 person lifeboat would be approximately 9.6m. So if fitted at a single level they would take up a length of over 210m (noise-to-tail) on each side of the vessel.

The new CRW55 mega lifeboat has a catamaran hull with a length of 16.7m, breath of 5.6m, weights 17tonnes in stowed condition and 45tonnes when fully loaded with passengers and crew. It is fitted with two 170hp diesel engines providing a top speed of 6 knots and twin rudders for increased manoeuvrability.

The seating is arranged in two levels designed to reduce the time taken to board all the people into the lifeboat. The main cabin deck will seat 280 people in longitudinal benches and the upper seating area will seat 80 persons in longitudinal benches and another 10 in the large steering tower near the helmsman’s position. The lifeboat also has an onboard toilet {ONE} and two stretchers stored in the wheelhouse."

Just off OASIS where I noted ... four mustering stations are assigned to one lifeboat. The lifeboat has 4 loading doors. Each door is marked with a number/color/shape corresponding to symbols on the seat positions. This is necessary to meet the rules for "loading time"

So that means it's possible you could get a liferaft as opposed to a lifeboat? If so, make sure you grab sunscreen from your cabin

Modern rafts are enclosed

I stand corrected. Thanks @Capt_BJ

I think it's just Royal Caribbean that has these giant lifeboats with one toilet for 370 people.

Most of the places Disney sails are not far from land and in the major shipping lanes. I would guess that with the exception of the TAs that the lifeboat passengers would get picked up by other ships or make it to land relatively quickly.

You are right-missed that part. Pretty impressive though!
