In this manuscript, we handle a tubular surface whose Gauss map G satisfies the equality L(1)G = f(G + C) for the Cheng-Yau operator L-1 in Galilean 3-space G(3). We give an example of a tubular surface having L-1-harmonic Gauss map. Moreover, we obtain a complete classification of tubular surface having L-1-pointwise 1-type Gauss map of the first kind in G(3) and we give some visualizations of this type surface.
