Habitat Entrance

Moonpool of Hydrolab

(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.

BIOSMHARS

Bacteria isolated in dairy product (representative image)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.

Undersea Station Draft No.4: Hangar

Undersea Station Draft No.4; Module 1; overview
Module 1; overview (preliminary rendering; V26-04-2018)

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”

‘Project Undersea Station’ Introduction

Wordpress Header (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”

Leben und Arbeiten im Meer

(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”

Living and Working in the Sea

Living and Working in the Sea(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.

Breathing Gas Processing: Overview

Breathing Gas ProcessingUpdated 13.08.2017 (added chapter ‘sources’)

Living in an underwater habitat requires gas treatment; an input of oxygen, the disposal of carbon dioxide and pollutants, and one kind of ‘carrier’ or inert gas (nitrogen or helium). Industrial divers live in a pressure complex on a support vessel and all air treating is done outside the habitat on the vessel. It seems there are not too many references of air being treated inside an underwater habitat. If we are mistaken do not hesitate to comment this article accordingly.

Wireless Sensor Network (WSN)

Control Panel in UWL HelgolandSeveral years ago Benjamin proposed a system of sensors inside the habitat measuring all necessary parameters like oxygen, carbon dioxide etc. and communicating among each other. Last days we talked about it again and found out, that it would still be a good solution. So we decided to publish it here again. Below you find the original thread, translated from German: Continue reading “Wireless Sensor Network (WSN)”

Financing an undersea station

financing an undersea station

(Updated 07.06.2017; added crowdfunding, daily turnover by educational institutions and underwater archaeology) 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”

Augmented Reality Underwater

Augmented Reality Underwater by Hololens in Neemo 21How helpful would it be to have Augmented Reality underwater in a closed environment like an Undersea Station? NASA experimented with Augmented Reality (AR) or Mixed Reality (MR) by using Microsofts HoloLens at the Aquarius Reef Base off the coast of Key Largo, Florida, in late July/August 2015. Potential astronauts used the device for tasks like checking emergency breathing equipment. Therefore they were going through a series of steps ranging from turning valves to finding and plugging in equipment, and setting up equipment to support an undersea robot.

Underwater Station: Virtual Porthole

Virtual Porthole inside the Underwater StationHere is an idea for a porthole where the structure of the underwater station does not allow to install one. For example on the ceiling, where penetrations of the shell should be strictly avoided in order to maintain the integrity of the emergency safety area in the upper part of the living area. The Virtual Porthole would consist of a camera on the exterior of the shell and a TV flat screen on same position inside the habitat. Continue reading “Underwater Station: Virtual Porthole”

Undersea Station Dietary: Mana

To provide food to the Aquanauts might be more difficult than thought concerning changing weather, water/pressureproof transportation, as well as emerging odours and chemical compounds inside the habitats atmosphere.  A complete or partial solution could be a meal replacement like Mana. MANA is a balanced food providing all nutrients the human body needs. It comes in the form of drink or powder being produced in Prague. Learn more on their webpage.

Aquanaut Decompression

NEEMO Diver under Aquarius HabitatTo stay in an underwater habitat longer than 12 hours means to stay under saturated conditions, which requires an aquanaut decompression sequence of at least several hours. This decompression procedure is very critical: if any of aquanauts gets into an emergency situation, there is no way to take him out of the chamber before the sequence is finished. If the procedure is badly designed there is no way to bring a paramedic into the chamber. For the period of several hours the aquanaut would be alone with his companion.
