Brent ,
The annular tank is great
for saving space. Corrosion is a concern. We apply a coating in the tank by
putting 2 litres
of coating in and turn the sub around.
That will hold 20
years. Then you have to make 3-4 inspection hatches in..
Horizontal weldment is a “slingerschot”
don’t know the English name but it is to get more stability with half
filled tank.

Greetings Emile
and Carsten,
I've been meaning to ask you guys about the annular hard tank your installing
between two stiffener rings. Will it be just one tank or have a type of baffle
arrangement? I see one horizontal weldment on the left side of the
picture. Will you weld on the inner tube section that completes the tank,
or bolt it on some how? I'm mostly thinking of how to deal with corrosion
in that tank. Have you made any drawings of that tank?
"inside view.
note the hull is on its side. Later the space between the frames will be
closed. Then we have a strong stiffener and annular hardtank."
