Underwater Navigation

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).

Habitat Entrance

The moonpool of habitat Hydrolab
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.

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”

The Gig on the Rig

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.

CalamarPark Deck-Shirt

The CalamarPark Deck-ShirtFor working and relaxing on deck we created this deck-shirt. We noticed that after a dive you are often shivering, while staying in the sun leads to a sunburn and the shade might be to cool. We needed a shirt that protects partially from the sun and its reflection from the water surface without keeping the summer heat in it, and still leaves the wind through its textile. We also wanted to cover our head without to be forced to wear a cap, that heats up even more and is easily forgotten on the boat. Continue reading “CalamarPark Deck-Shirt”

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)”
