It is only a document with info I found interesting and then, sorted by chapters.
*Station keeping costs: yes, I have made a very, very rough estimation, but the conclusions should be the same: DP is not so expensive in operation, and mainly in benign enviroments. I will post the idea in the blog in following days. Something to discuss!!
* Heavy fuel or Diesel: most of small generators use diesel. Heavy fuel is used mainly in big engines and requires an expensive intallation for heating the bunker tanks. It is used for example in big oil tankers that have already a heating plant for the cargo tanks...In any case, gas is cheaper than diesel. Some vessels, not being LNG tankers that of course uses gas, are being powered by gas in recent years, but still on progress and not widely used: only some ferries and offshore vessels in Norway. But very promising !!!

Wow, you type way faster than me. (im only able to work on this a few hours a week at the moment unfortunately)
I havnt read it completely in detail yet, but something that stood out to me in the sectio non station keeping costs:You assume residential power consumption to be roughly equal to that which the production system would consume. But 50MW is quite a bit of power; the average houshold uses only a handfull of kW on average, no? So how many households are you envisioning on that seastead? That seems like a high-end estimate to me. Either way, it doesnt affect the conclusion, which I fully agree with; for a large, ship-shaped seastead, station keeping costs are small relative to other operating costs. Great to have a solid reference on that!Another thing; would we be able to burn bunker-fuel on a seastead? Ships do it all the time, of course, but especially if starting out at a fixed spot in an EEZ, it might give others a stick to beat us with. I dont know really, but it would be nice, as its quite a bit cheaper than diesel! (not sure why MI&T decided to go with diesel; perhaps they felt the black smoke would be incompatible with a high-end casino?)EelcoFrom: Miguel Lamas PardoSent: Thursday, May 27, 2010 5:59 PMSubject: Dissertation draft_2010-05-27Hi Patri, James, Eelco !I send you updated draft version of my Ph.D thesis.I am trying to organize the ideas and concepts that could be useful for seasteading and put in chapter 2, State of Art. Nothing more, but it takes time!!!Regards,Miguel

In principle, I have not a fixed date. That depends on:* the activity here at the yard. Now I am able of dedicate some hours, but perhaps in following weeks this situation could change.* the quantity of info required in the thesis. I have seen some thesis with only 200 pages, and others with 500 pages!!In any case, my idea is doing the official lecture before the end of the year, but separate chapters could be published before.Regards,Miguel Lamas

Agreed; I like having the activity in the engineering blog to show people what progress is being made. Good stuff.Re: Publications -- sounds like it makes sense for the papers that Eelco's is writing to be the official TSI papers. To write those papers, he'll develop knowledge based on your dissertation drafts (which you are privately sharing with us), your blog posts, discussion with you, and of course all of his own research. That should work fine -- it will allow you to help us further our engineering knowledge, and to contribute to TSI's publication, without us needing to directly pull extensive material from your dissertation before the official lecture.And yes, we can certainly post your PhD after it is completed! (When is the official lecture, by the way?)

Thanks a lot for writing that; I also think it is important to show people some progress. There may be much that is not yet certain enough to expose publically, but this is a good example of a nice bit of information we can all agree on.From: Miguel Lamas PardoSent: Monday, May 17, 2010 12:35 PMSubject: Re: Advantages of offshore concrete structuresThank you very much Naomi! As explained, my idea it to post in the blog twice per month in order to show that some little engineering research is being done. I have seen in the main blog that some community members have some doubts about that, :-)Patri/James, regarding the big engineering document, I have a little problem: as it is a PhD dissertation I was told that I can not publish it before the official lecture. But on the other hand, it would be better for me to share it with TSI staff and community members in order to obtain a feedback. I have been thinking in two options:* Option 1: I could update the whole document as a google doc, as your proposal, but only for your internal use: TSI staff, engineering colaborators, donors,...* Option 2: to publish the finished parts in the research site, as the PhD thesis from Galea, or the report from Eelco.Or even better, option 1 and option 2 together.

Hey Miguel,Nice post -- and very few English problems. :)I changed a bit of formatting to make it fit better in our website. If I've made any changes that don't look right to you, let me know.Thanks!!--Naomi--
