Mart will have a presentation about “Underwater habitats for use in marine research” at the eleventh annual meeting of the International Symposium on Underwater Research (ISUR). Hope to see you there.
(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”

HUNUC (abbreviation for Habitat of the University of Natal Underwater Club) was South Africas first underwater laboratory. However, the facility was destroyed shortly after its positioning due to conceptual errors and bad weather conditions. Continue reading “HUNUC”
Aquanaut Sylvia Earle, co-leader of the final mission to the world’s only undersea lab, says the oceans need protecting more than ever – don’t pull funding
(Update 29.08.2018: Added water air membrane; oxygen by electrolysis. Dieser Artikel steht unter “Atemgas” auch auf Deutsch zur Verfügung) This article is intended to define the concept for ensuring the appropriate habitat atmosphere to be used in the Calamar Park modules. Continue reading “Breathing Gas Processing: Overview”
In 2016 deep sea technology developer Dr. Phil Nuytten had a TEDx speech about his vision of an underwater habitat called Vent Base Alpha. It would generate the necessary energy from the geothermal vent next to its location and would consist of a 1bar environment. (Video length 19:08 min.)
(Update 29.08.2018: Wasser-Luft-Membran und Sauerstoff durch Elektrolyse hinzugefügt; the english version of the following chapter is available under “Breathing Gas Processing“) Dieser Artikel soll das Konzept zur Gewährleistung der geeigneten Habitat-Atmosphäre festlegen, das in den Calamar-Park-Modulen verwendet wird. Continue reading “Atemgas”
(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:
The danger of excursion divers getting lost have always been a major concern in underwater habitats. According to their webpage the Dive Tracker consists of a sender and a tracker. From a distance of up to 4000ft (≈1300m) divers can easily track the direction of the sender’s signal and return to their safe location. Costs: from 1200USD per set. (Homepage Dive Tracker).
(Updated 24.05.2018; added wet room configuration, scuba tank refilling installations and summarizing requirements list) 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.

The kind of fire extinguishers for an underwater habitat is an important issue. It should be effective, but must not contaminate the entire atmosphere. A considerable solution might be the Bioversal technology represented by Gröschl Brandschutz GmbH (former Bioversal Umwelttechnik und Handels GmbH) in Austria. Continue reading “Bioversal Fire Extinguishers”
BIOSMHARS was a 2-year (2011-2013) research project co-funded by the European Commission under FP7. It was the first phase of a joint EU-Russia research effort to develop the scientific and technical tools for a comprehensive approach to the challenging issue of biocontamination inside manned spacecrafts. (project page; final report as pdf)
Update 27.04.2018: added new renderings) So far the final draft follows the hangar shape. Having a look at the evaluation list in the ‘Structural Shape‘ chapter it seems like the ideal shape for the undersea station.
Because of the sand used as variable ballast and the space under the station the structure is easily removable by just releasing the sand. No harmful materials or items would be left behind which serves the ecological idea. Continue reading “Undersea Station Draft No.4: Hangar”
(updated 25.04.2018; added preliminary renders) Project CalamarPark Undersea Station aims the development of a new generation of undersea settlements. Technically based on experiences of prior stations there will be several new considerations concerning expandability, size and usage. All results will be open-source (except some marketing details necessary for continuous popularity) and anybody who is interested has the chance to contribute his ideas. Until the minimum financial frame is completed we will go on collecting as many information as possible, implement them to a realistic blueprint and constantly improve the final design. Ultimately the final goal is the actual building of the habitat. Continue reading “‘Project Undersea Station’ Introduction”
(For English please scroll down) Zur Erinnerung: Ich hatte mich mit Dr. Jim Miller und Ian Koblick auf eine Übersetzung ihres Buches ‘Living and Working in the Sea’ (‘Leben und Arbeiten im Meer‘) ins Deutsche und insbesondere vom anglo-amerikanischen ins metrische Maßsystem geeinigt. Die Übersetzung und erste Durchsicht ist abgeschlossen und alle notwendigen Kontakte geknüpft. Der ursprüngliche Plan, die Veröffentlichung über Crowdfunding zu finanzieren, hat jedoch einen Dämpfer erhalten, weil alle Crowdfunding-Plattformen Projekte aus dem Land, in dem ich seit langer Zeit lebe, nicht akzeptiert. Ich brauche da also eine andere Lösung. Continue reading “Leben und Arbeiten im Meer”
If you have doubts whether concrete is an appropriate material for an underwater habitat then have a look at the supporting legs of Troll A, a condeep offshore natural gas platform in the Troll gas field (see Wikipedia en/de). The legs are air filled and reach 303m into the deep. In 2005 Katie Malua performed a concert on its basement setting a world record for the deepest underwater concert.
(For English please scroll down) (Update 17.01.) Nachdem wir uns mit Dr. Jim Miller und Ian Koblick auf eine Übersetzung ihres Buches ‘Living and Working in the Sea’ ins Deutsche und insbesondere vom anglo-amerikanischen ins metrische Maßsystem geeinigt haben, können wir nun bekanntgeben, dass die Übersetzung inzwischen abgeschlossen ist. Momentan arbeiten wir an der Durchsicht und hoffen, in Kürze die Veröffentlichung beginnen zu können. Mit letzterem ist innerhalb der nächsten zwei Monate zu rechnen.

This chapter aims to find preventions and handling to reduce risks of a lightning strike. All proposals that may help to improve it are welcome. Continue reading “Worst Case: Lightning”
