Ryanair and the 737-700

I have noticed on planespotters.net that it shows Ryanair have got an unregistered and stored 737-700. It is 16 years old. Does anyone know what is going on with this?
Thanks.

I don't think this site is too accurate: http://www.planespotters.net/Airline/Ryanair
Because they don't have 6 on order.
The -700 says it has been delivered in 2015??? http://www.planespotters.net/Production_List/search.php?manufacturer=Boeing&subtype=737-700&fleet=1952&fleetStatus=2
Maybe they use it as an extra, but I don't believe so because with such a big fleet and the new income of new aircraft they surely have surplus.
I think they still have 270 to be delivered. (100 of them are MAX200) , correct me if I'm wrong.

If you want good info on their fleet, I use this site: http://www.flightradar24.com/data/airplanes/ryanair-ryr/
Its great, because you see their airplanes currently in sky.
And you can see the new delivered aircraft. Newest one currently is EI-FIL (it's still in Seattle)

I don't understand because EI-FIG is one of the newest ones, newest registered but it still has the old livery?

It might have been re-registered. Is there even a new livery? Perhaps its just minor painting errors?

Cheers!

I guess the livery has changed!
EI-FIK 2nd newest one, taken in this pic on the 15th May, has the new livery.
The blue seems to have gon darker, much darker?

EI-DCM (older one): http://www.planespotters.net/Aviation_Photos/photo.show?id=601741&from=flightradar_200

It seems they do have one. Why?
Here is a picture of the plane in an uncompleted paint scheme

This is it http://www.flightradar24.com/data/airplanes/ei-sev/
EI-SEV type-700
Is it an extra aircraft?

yes it is to be used for crew training and used as a spare if one has a technical problem or delayed

Yes its used for training.

It flies from EMA, just where the East-Midlands Ryanair training center is.
Used for pilots only I think.

Thanks. Do you know if there are plans for more -700 aircraft?
