Some things to keep in mind for the economies of a nuclear powered merchant vessel... You will have about 30% more engineering staff, and these people will have specialized skills so they will earn more than your typical marine engineer. There are additional shoreside support requirements for refue...

Perhaps yes, this could be done. But it would be a very large reactor, which woulld be heavy. Read carefully this link: http://www.eng-tips.com/viewthread.cfm?qid=104814 That thread is kind of confusing. There's a lot of stuff about plutonium and space reactors. The formula I assume I'm supposed to...

Ok, I'm going to reboot this discussion with some questions: How well do hull shapes scale on container ships? How much commonality can be achieved from the keel up between vessels in different DWT/TEU classes (e.g. from Old Panamax to E-Class to Triple E-class etc.)? I'm envisioning maybe 3 differ...

What are we even talking about again? I'm already leaning toward ditching the forward pilotage idea in favor of a more conventional bridge placement. We're getting WAAAY off track here.

I don't think a split layout is going to make sense on a ship of that size without the need for forward tankage. You're losing an entire cargo hold that way. By split layout, I assume you mean the superstructure and space beneath it being located amidships? What would be a better option? Locating t...

It depends on what restrictions and requirements the ship has to live up to. Sevmorput is designed to carry LASH barges around the high Arctic. And she was designed in the Soviet Union. That has some fairly major effects on the design. The forward superstructure is a result of the LASH barges. They...

With all that said I do agree that the bridge will probably be placed somewhere between a third and two thirds aft from the bow for the above reasons. Front control has some serious structural implications on larger ships that aren't easily overcome. After all you're basically hanging a large weigh...

Could the coolant issue be mitigated through the use of an electrical heating element connected to shore power or a large battery for emergencies? I know they used something like that to pump frozen fuel out of the drain tank of the MSRE at ORNL, and FliBe has a much higher melting point than LBE. T...

What is your point? I know the pros and cons of LFRs, as do the engineers who design and seek to build them. The sole point of bringing up the Russian example (which is relatively primitive 60s tech and would be far inferior to a 2010s Western design) was that they can work, and that the Gen4 propo...
