Undersea Station: Initial Financing

financing an undersea station

(Updated 16.05.2020; split article into initial and operational financing, added Ithaa as example for tourism) 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.

At the same time this article may also be used as a guide for potential investors to get inspired about how to benefit from an underwater habitat.

Regardless of the type of use, safety is the top priority. This means that even for tourist, private or entertainment use, certain limits remain. An underwater station is a facility in an extreme environment where clear rules must be followed and any move towards an amusement park where these rules are to be lifted is not welcome.

It should be taken to account that an underwater habitat might serve several different sectors at the same time, e.g. tourism and marine science and education.

Potential Partner Sectors

Marine Sciences / Oceanography

Scientific institutions are still first choice since an underwater laboratory meets their field of interest. Educational institutions would receive a laboratory in the most unusual location and environment. They will be able to conduct trainings in oceanography, biology and engineering at the land base, around the habitat and inside the habitat. They will be able to broadcast from their missions to all of their students live over the internet, and let them join interactively. Student groups from several countries will be able to visit the location, boosting the brand of the connected local university.

According to the investment they will be able to use designated panels on the outer shell and certain interior areas as well as participant uniforms for placing their logos and use them for advertising purposes. Some of our mission proposals will maintain high media coverage and therefore represent a high degree of advertisement internationally.

In return we would offer beside the main habitat a smaller habitat that can be positioned in other locations. It could operate separately or keeping in touch with the main habitat and the institution live online.

While the habitat will be accessible for other participants when it is not used by the institution, the modular concept of the main habitat allows extensions according to different requirements only accessible for members of the institution. Therefore it will be possible to add other modules to the main body. Each module will contain a corridor to reach every part of the structure without to be forced to pass each room.

The initial investment granted by one ore more parties at the same time will be calculated to cover at least one year of operation consisting of each a six months construction and operation period. Any funding for further operation (see daily financing below) will be recalculated.

An overview of missions at Aquarius Reef Base is available on the webpage of Florida International University > Past Missions as well as a reference pricelist for missions onboard Aquarius.

Companies of any sector who want to support a thrilling project like an undersea habitation to advertise will be able to use the already mentioned panels on the outer shell and certain interior areas as well as participant uniforms for placing their logos. The habitat name might be something like ‘The Fisher Steel Habitat‘ or ‘Smith Insurance Station‘ for the duration of the contract. Some of our mission proposals will maintain high media coverage and therefore represent a high degree of advertisement internationally. The panels will be attached in such a way that they will be visible on all photos and videos. Coverage will start during construction and continue during positioning and operation.

The habitat will be offered for missions to educational institutions or civilians. In this case they will be able to receive more affordable rates, but use less advertisement areas in return, since they are separated from the main sponsor.

The advertisement areas might also be shared by more than one advertiser, which reduces the costs per company. The initial investment will be calculated to cover at least one year of operation consisting of each a six months construction and operation period. Any funding for further operation (see daily financing below) will be recalculated.

However any advertising agreement has to be made for a certain period of time (initial phase), after which advertising panels will play their role in maintaining  daily turnover (operational phase).

Underwater Archeology

Underwater archeology is a permanently underfunded sector. Generally studies take place in shallow waters with standard tank diving, ROV’s or submersibles. While the number of tank dives per diver as well as the length of the single dives is strictly limited and ROVs do not replace human presence, submersibles do not provide a possibility to enter the surrounding ocean. Talks of the potential of underwater habitation for underwater archeology between us and senior archeologists showed, that there is a certain need for a mobile habitat deployable for depth up to 20m. Operations like that would allow several dives per day with long bottom times. Habitat missions would have a great impact on …

  • the mission results (higher number of longer dives)
  • its outreach to the public (by attracting media)
  • the sector itself andtherefore
  • funding for future missions.

Private Supporters

As a private supporter you will be part of a spectacular project that aims to provide a platform, that in the future might lead to settle human beings on the ocean floor. The volume of the initial project is absolutely variable. Since the concepts contain modularity as a main feature, each module can be subdivided according to the available funding. The minimum amount for a first project still has to be calculated, but it seems like being around 150.000 € for a small habitat, that will act as a development platform (e.g. for docking techniques) and as an attractor for further investments. It will be a mobile habitat to be used in different environments and later be fully integrated in the following main structure.

Later there will be a possibility to rent a complete room inside the habitat for private purposes like a laboratory or hideaway. Except the technical staff and official controls nobody will be able to enter that room.


Tourism has always been forced to stand out from the crowd and create new attractions. Many of these attractions were not intended from the outset to amortize their own expenses, but rather to act as a magnet for new customers. A good example of this is the underwater restaurant Ithaa.

Ithaa is located in Conrad Maldives Rangali Island in the Alif Dhaal Atoll in the Republic of Maldives and consists of a platform of 9m length and 5m width, which is completely covered with an arch of acrylic glass. It contains a restaurant for 14 persons, which can be reached via a staircase from a jetty. The costs for this project amounted to 5 million dollars in 2004. Even with food prices of 200 dollars per person, 25,000 paying guests would be necessary to amortize the costs. This would mean that the facility would be fully booked twice a day for 892 days; this does not include the running costs for personnel and food, which are about 30% of the sales price. The estimated life span of the restaurant is 20 years.

The intention of such an investment is clear: apart from the direct income from daily operations, which recoups a certain part of the investment, the gain in attractiveness for the hotel complex cannot be measured. There is no doubt, however, that Ithaa made the hotel known worldwide and provided a reason for choosing the hotel complex as a holiday destination. It is worth noting that classical advertising with a budget of 5 million dollars would certainly have generated less response and would have been much more short-dated.
By the way, the habitats proposed by CalamarPark can be realized for much less investment.



Space Agency Trainings





Crowdfunding sounds like an easy solution for getting the initial financing, until you have a look at the statistic below.  (for all non-germanophones:) As you can see technology projects are on the third place after games (!) and design projects in terms of collected amounts. Still a very promising number.

But on the right you can see the percentage of successful projects stating that only 20% of technology projects were actually successful, which is the worst result of all sectors.

So, this is the problem: even the most simple undersea station is costy, at least more costy than a painting exhibition.  With higher amounts the probability of collecting enough drops. To get the best result we have to promote the camapign and focus all interested people and our entire network to the campaign. If this campaign fails by not generating enough money we might lose participants and credibility.

See as an example the SeaOrbiter project of Jacques Rougerie. The probability to get this great concept financed is low. What he did (and what we try to do, too) is to divide the constuction into modules and offer them for example to the crowdfunding community. The campaign to construct the ‘eye of SeaOrbiter’ generated 345.000 € (!) in 2015, 6% more than the targeted amount, and covered the construction of the shell of that module, which awaits next steps ever since. Not to be misunderstood: it is a great project and we really hope that it will be finished one day, but if the shell of a small module takes years to be funded, how long takes the complete construction then. While the ‘eye of SeaOrbiter’ is not usable alone we have to target from the beginning a small module, which is completely implementable into the end concept, but also usable as a stand-alone module, similar to the International Space Station (ISS).

So here is what we have to do before turning to crowdfunding:

  • Split the concept into the smallest full functioning module
  • Keep the price as low as possible
  • Try to attract and include as many sectors as possible
  • Find out the probability of being successful
  • WAIT (!) until the probability is high enough
  • Create a convincing presentation
  • Agree on the best date to start the campaign
  • Do it!
