General Requirements of Human Beings

To build an underwater habitat we have to know the measurements of human abilities, his limiting values and restrictions. In 2010 NASA published the Human Integration Design Handbook which gives answers to most of these questions. Though it is meant for space flight we can easily adapt most of it to an underwater application. The handbook is available as *.pdf on the server of our digital library. Contact Mart for access.

11th International Symposium on Underwater Research

Mart will have a presentation about “Underwater habitats for use in marine research” at the eleventh annual meeting of the International Symposium on Underwater Research (ISUR). Hope to see you there.

21. Sualtı Bilim ve Teknoloji Toplantısı

16-17 Kasım 2018 tarihleri arasında, “Kemer Deniz Bilimleri Haftası 2018” kapsamında düzenlenecek olan 21. Sualtı Bilim ve Teknoloji Toplantısı’nda, “Deniz araştırmalarında kullanmak üzere İnsanlı Sualtı İstasyonları” başlıklı konu altında Mart tarafından sözlü sunum yapılacak.

 

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

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 11.03.2023: structure renewed) This article is intended to define the concept for ensuring the appropriate habitat atmosphere to be used in the Calamar Park modules.

It is divided into the following sections:

  • Guide Value for Electricity Costs
  • Oxygen
  • Oxygen Demand of a Human Being
  • Oxygen Availability
  • Carbon Dioxide
  • Normoxic Gas Mixtures (Normox)
  • Air Supply from the Surface
  • Carbon Dioxide Scrubbing by Soda Lime
  • Carbon Dioxide Scrubbing by Monoethanolamine (MEA)
  • Carbon Dioxide Scrubbing by Sea Water
  • Photosynthesis
  • Water-Air Membrane
  • Oxygen by Electrolysis

Our extensive analysis and proposals are part of the design manual.

Vent Base Alpha

In 2016 deep sea technology developer Dr. Phil Nuytten had a TEDx speech about his vision of an underwater habitat called Vent Base Alpha. It would generate the necessary energy from the geothermal vent next to its location and would consist of a 1bar environment. (Video length  19:08 min.)

Worst Case Scenarios: Introduction

worst case(Update 23.12.2022: renewed structure) This chapter is an introduction for the creation of various worst case scenarios, their prevention and handling.

The results of each scenario naturally link to two different applications:

  • structural measures of the habitat (to be considered during planning and construction of the habitat)
  • emergency procedures (to be considered before accommodation)

This chapter is an introduction and covers the following sections:

  • Coverage
  • Combinations of Multiple Emergencies
  • Deactivation of Overwrite Rule
  • Levels of Emergenvies
  • Structure of a Worst Case Scenario
  • List of Proposed Scenarios

Our extensive analysis and proposals are part of the design manual.
