Undersea Station: Water Supply

Water Supply: Image by James Petts from London, England (Stream of water) [CC BY-SA 2.0 (http://creativecommons.org/licenses/by-sa/2.0)], via Wikimedia Commons(Updated 09.02.2020: link concerning average need of water for a human being updated) Event though our station is surrounded by water we can not use it for most of our needs. Therefore for some demands we have to establish a sweet water supply. The easiest way is to bring sweet water from the shore and to fill corresponding tanks. Well, what kind of water do we need?

Financing an undersea station

financing an undersea station

(Updated 15.12.2019; added new aspects for daily turnover) The most professional underwater habitat so far is still the Aquarius habitat in Florida. This quality comes to a certain price of $1.2 to $3 million per year. Due to budget cuts, NOAA ceased funding Aquarius habitat after September 2012, with no further missions scheduled after a July 2012 mission. It was a very exciting period having the facility on risk. It took until January 2013 when a proposal to keep Aquarius running under Florida International University administration was accepted. What could we do in future projects to avoid sooner or later close-downs by lacks of financing? Continue reading “Financing an undersea station”

Habitat Entrance

(Updated 06.07.2019; added access space details, feature list and first sketch) Surely one of the most complicated area of an underwater structure for human occupation is the habitat entrance. It is the local water-air interface, vulnerable to changes in pressure by tidal movements on the surface of the sea; its hatches have to bare potential pressure differences between the habitat interior and the surrounding water; no object that is only a little bigger than the greatest diameter of the entrance can be brought into the habitat. It is constantly wet and humid and the only gateway for medical assistance. But to see in detail let’s have a look at the different sections of the entrance complex.

General Requirements of Human Beings

To build an underwater habitat we have to know the measurements of human abilities, his limiting values and restrictions. In 2010 NASA published the Human Integration Design Handbook which gives answers to most of these questions. Though it is meant for space flight we can easily adapt most of it to an underwater application. The handbook is available as *.pdf on the server of our digital library. Contact Mart for access.

Branch & Bound

(Guest article by user Mike, thanks for contributing) By common definition, Branch & Bound is a mathematical algorithm to solve integer optimization problems. But simplified versions of Branch & Bound are also applied to find best fitting technical solutions manually. It is a useful tool for making fundamental decisions, such as the selection of a synthesis route during the project development of a new chemical factory complex.

In the context of CalamarPark, the design of the underwater habitat is such a fundamental decision: Should it be small or large? To operate at what depth? Ambient or atmospheric pressure? A certain design might be perfect at one location, but only second choice at another. Continue reading “Branch & Bound”

Worst Case Scenarios: Introduction

worst case(Update 22.06.2018: Expanded list of proposed scenarios) In this category we would like to list potential “Worst Case Scenarios”, their prevention and handling. The results of each scenario naturally link to two different applications:

 

  • structural measures of the habitat (to be considered during planning and construction of the habitat)
  • emergency procedures (to be considered before accommodation)
