Stowage & Inventory Management

This section discusses design considerations for the layout and design of stowage systems inside an underwater habitat. It also provides the characteristics of a successful onboard inventory management system design. Such a system can track the quantity, location, and status (e.g., remaining useful life) of inventory items. The inventory management function is one of the primary elements of onboard information management. Continue reading “Stowage & Inventory Management”

Nutrition

For long-term stays in an underwater station, a plan for ideal nutrition is required, which takes into account the special circumstances such as increased-pressure environments and reduced sunlight. This section will discuss the specific requirements and the resulting dietary recommendations, which include environmental considerations (avoidance of waste…), safety precautions (avoidance of contamination of the habitat atmosphere…) and alternative sources of supply (own production, finished products…). Some considerations will require a certain design of the corresponding habitat sections. Continue reading “Nutrition”

Habitat Entrance

Moonpool of Hydrolab

(Updated 04.07.2020; added new visualizations; minor additions/corrections to access tunnel) 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.

Undersea Station: Operational Financing

(update 31.05.2020: integrated article ‘event plan’; adding section ‘science (general)’, entertainment, space agencies; extended ad section; article under progress!)

IMPORTANT NOTE: This article is similar but not identical to Initial Financing. For information on the other matter please visit the corresponding article.

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, bringing the whole facility under risk. It took until January 2013 when a proposal to keep Aquarius running under Florida International University administration was accepted. What can we learn for future habitats and what could we do then to avoid sooner or later close-downs by lacks of financing? Continue reading “Undersea Station: Operational Financing”

Undersea Station: Initial Financing

(Updated 30.08.2020; added section Research on Medicals from the Marine Environment)

IMPORTANT NOTE: This article is similar but not identical to Operational Financing. For information on the other matter please visit the corresponding article.

In the past years we have seen that it is very difficult to attract investors for the initial building of even a small habitat. In the beginning we concentrated on scientific institutions who always were very interested, but not able to lift the initial costs. Before we start to calculate the initial costs we should define the sectors of potential application, rethink the habitat design to cover the demands of as many of these sectors and then refine the initial costs. Continue reading “Undersea Station: Initial Financing”
