Housekeeping

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.

This chapter is divided into the following sections:

  • General Considerations
  • Habitat Specific Risk Areas
  • Contamination Sources
  • Housekeeping Tools
  • Housekeeping Minimization through System Design
  • Past and Present Housekeeping in On-Orbit Operations

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

ESA Qualification

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

Scene from Aquarius Habitat(updated 15.09.2020: added adaptations from the NASA Human Integration Handbook) 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.

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

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.

This chapter is divided into the following sections:

  • General Considerations
  • Type & Locations
  • Nonstandard Stowage
  • Habitat Resupply
  • Flexibility
  • Central Storage vs. Distributed Storage
  • Operability
  • Accessibility
  • Interference
  • Labelling
  • Inventory Management

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

Mooring

This chapter collects information on mooring of an underwater station, potential difficulties and solutions. Continue reading “Mooring”

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. Contact us for access to the whole article.

Undersea Station: Portholes

(Update 10.04.2023: complete makeover of the article; replaced outdated information; added new aspects from different sources like NASA’s Human Integration Handbook, 2010)

Windows are essential and present the most important reason to operate an underwater habitat. They are necessary for operation, safety and marketing.

This chapter is divided into the following sections:

  • Traffic
  • Tasks
  • Lighting & Glare
  • Windows Support
  • Condensation Prevention System (CPS)
  • Window Replacement
  • Window Covers

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

Interior Lighting

(Updated 10.04.2023: complete edit of the article) Lighting in the main habitat will consist of different modes: standby, activity, emergency and disinfection. This section should explain the ideal system of lighting inside the underwater habitat.

This chapter is divided into the following sections:

  • Lighting Modes: Standby, Activity, Emergency, Disinfection
  • Virtual Sky
  • CoeLux – Mimic Natural Refraction Process

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