The invention relates to a tank for storing and / or transporting a fluid and intended for a ship having a longitudinal direction (X), the tank comprising: · a column for loading / unloading the fluid, · a first
sump (30) provided in a bottom wall (23), · a supporting foot (31) fixed in an area of the bottom wall, the column comprising at least three vertical masts (11, 12, 13), two of which are arranged in a first
transverse plane (P1) orthogonal to the longitudinal direction (X), the masts (11, 12, 13) delimiting, by
axial projection onto the bottom wall, a first perimeter, the column bearing a first pump (20) entirely arranged outside the first perimeter and extending into the first
sump (30), the supporting foot (31) being arranged in a second
transverse plane (P2), parallel to the first
transverse plane (P1), the first pump (20) extending in a third transverse plane (P3), parallel to the first transverse plane (P1), the first transverse plane (P1) and the third transverse plane (P3) being situated one on each side of the second transverse plane (P2).
