Discussion Overview

The discussion centers around the feasibility of designing a ship that can withstand extreme wave conditions without sinking or being destroyed. Participants explore theoretical and practical aspects of ship design, including material requirements and structural integrity, as well as the economic implications of such designs.

Discussion Character

  • Exploratory
  • Debate/contested
  • Technical explanation

Main Points Raised

  • One participant questions whether a large ship could be designed to withstand wave pressure without structural failure, suggesting the need for advanced materials like those from the carbon group.
  • Another participant argues that while making a ship unsinkable is theoretically possible, the economic viability of such designs poses a significant challenge.
  • Concerns about scaling up designs are raised, with a participant noting that material strength increases with size but stresses increase more dramatically, complicating the structural integrity of larger vessels.
  • A proposal is made for a design using a series of "wine bottles" as a potential solution, although questions about the practicality of this approach are also raised.
  • One participant emphasizes that while waves may not be the primary threat to large ships, collisions with solid objects, such as rocks, pose a significant risk to hull integrity.
  • Another participant suggests that a flexible design could better absorb and distribute the forces from waves, contrasting with rigid structures that may fail under pressure.
  • It is noted that most large ships are more commonly sunk by factors like grounding or fire rather than by wave conditions.
  • Submarines are mentioned as a comparison, with the understanding that they operate at depths where wave effects are minimized.
  • One participant concludes that with sufficient funding and engineering, creating a resilient ship is theoretically possible, even with conventional materials.

Areas of Agreement / Disagreement

Participants express a range of views on the feasibility of creating an unsinkable ship, with no consensus reached. Some agree on the challenges posed by wave impacts and structural integrity, while others highlight economic and practical limitations. The discussion remains unresolved regarding the best approaches and materials for such a design.

Contextual Notes

Participants note limitations related to the scale of designs, the economic implications of advanced materials, and the need for flexibility in structural design. The discussion also highlights the distinction between threats from waves and other hazards like grounding or collisions.

Is it possible for a large ship, say 100 meters long at least, be sufficiently protected that the pressure exerted by any possible waves is not enough to rip the vessel apart? Would this require new structural materials such as the carbon group, because current materials would have to be too thick?

Also, can a vessel be made that will always right itself as long as it's intact?

Yes - assuming you are prepared to pay enough and have little enough room for cargo.

The difficulty isn't make a ship unsinkable, it's making a ship economic
 
the difficulty is one of scale. wine bottles have made incredible voyages. I suspect that a one order of maginitude scale up might work. past this scale that material strength increases as a square while stresses vary as a cube. imagine a ship traveling at hull speed in in a fifty foot wave train. think of the structure a a bridge bridging the wave trough ; forces become impossibly large if any rigidity is to be retained. In fact larger ships do flex as do skyscrapers. the "edmund fitzgerald" ( a modern ore friegther that sank with cause in lake superior" shows what can happen to wit structural failure from exceeding the elastic limit of the structure.

A string of "wine bottles" might have a chance. perhaps they could be made into a kind of raft pulled by tugboats fore and aft. very large log rafts have been hauled this way.
each of the containers could be shipping individual containers

What happens when the wine bottles hit rocks?
 
Waves won't be an issue to any hermetically sealed and structurally durable design, the issue, as some people already pointed out is the potential solid objects the waves might hurl the ship into and thus destroying the hull integrity and sink it.

You'd want to make such design more flexible and less rigid, in order to distribute structural load better across the entire ship. If it's rigid, pressure from impacting waves will break it. If it is flexible it will absorb and distribute structural shock better.
 
In practice very few large ships are sunk by sea state, far more common is running aground, due to losing power or bad navigation, or a fire.
 
Do submarines qualify?
 
Submarines travel at depths where most waves have little effect.
A surface ship would have to be very well sealed and flexible or stronger and heavier than would be cost efficient, but yes it could be done. (even with conventional materials)
Anything is possible with enough money and proper engineering.
