1. A method for manufacturing a vessel configured for housing a fluid within, said method comprising:
a) providing at least two inner Fiber Reinforced Polymer (FRP) structures shaped with complementary coupling interfaces configured to match with each other, such that an interior volume is defined when said inner FRP structures are coupled to each other;
b) coupling the inner FRP structures to each other;
c) providing at least two outer FRP structures shaped with complementary coupling interfaces configured to match with each other, such that a sheathing is defined when the outer FRP structures are coupled to each other, said sheathing being sized for encasing the inner FRP structures, contacting them on their outer surface, after they have been coupled according to step b);
d) coupling the outer FRP structures to each other, encasing the inner FRP structures, such that a relative position of the inner FRP structures is locked thereby; and
e) fastening the outer FRP structures after they have been coupled to each other.
