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”

Habitat Entrance
(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: 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”
Undersea Station: Data Processing
(Updated 15.05.2020 – Added noise recognition to Concept Map, improved article structure etc.) The Digital Data Processing of the station will be of major importance. Beside the conventional functions of the IT systems we should use the opportunity to establish a completely new approach concerning the User Interface (UI) and the system’s interaction with the aquanauts. Continue reading “Undersea Station: Data Processing”
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”

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”
Breathing Gas Processing: Overview
(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.
