Please correct this. Off-shore station

The offshore base station is designed to provide the structure needed for the space elevator. It is used to receive the payloads and to avoid problems with lamps of space debris. In order to be easily transported, the base station is located offshore. However, this there is a problem concerning to deliveries. Payloads have to must reach the station by ship, and they cannot stay at the base for a long time due to their weight.

The complex base station would be expensive, so it is important to make it as cheaper as possible. There are two main parts of the budget that cannot be cut: The first one is the expensive in materials since the structure must be made in of good, strong steel, light and that resists the action of the brine, and The second one is the size of the station, as since it has to be spacious enough for payloads in stock, strong enough to hold the cable and resist the waves if it was near to the shore.

It would be also necessary to supply it with a powerful system for propulsion because of the heavy cable. Apart from that, this powerful system would be useful in case an urgent moved is needed.On one hand, this structure could be very interesting to provide special stations with payloads and goods. On the other hand, it seems to be hardly viable because it is a very ambitious project with a huge budget. In conclusion, it is not clear at all certain that this project is profitable.
