Housekeeping in an underwater habitat is a crucial part of habitability. It plays a primary role in maintaining the cleanliness of the habitat and thus the crew’s health and safety, which will consequently boost their morale, comfort, and productivity. Continue reading “Housekeeping”
We are very happy that our proposal of an European Underwater Research Center has been qualified today by ESA to be presented for discussion and vote. So there is a realistic chance for funding of a detailed feasibility process leading to the construction of the first module(s).
Recreation is an important consideration for maintaining high morale, psychological and physiological health in an underwater habitat, especially for long durations. This section provides guidelines for recreational activities. Continue reading “Recreation”
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”
This chapter collects information on mooring of an underwater station, potential difficulties and solutions. Continue reading “Mooring”
(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.

(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”
(Updated 09.02.2020: link concerning average need of water for a human being updated) Event though our station is surrounded by water we can not use it for most of our needs. Therefore for some demands we have to establish a sweet water supply. The easiest way is to bring sweet water from the shore and to fill corresponding tanks. Well, what kind of water do we need? Continue reading “Undersea Station: Water Supply”
(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”
