Beat vegetable shortening and sugar with an electric mixer in a large bowl until smooth. Beat in one egg until completely incorporated. Beat in last egg along with vanilla extract and water. Combine flour, cocoa powder, baking soda, and salt in a small bowl. Stir flour mixture into creamed mixture at low speed until just blended; fold in chocolate chips. Drop spoonfuls of dough 2 inches apart onto ungreased baking sheets.
Bake in preheated oven until cookies are set, 7 to 9 minutes. Cool 2 minutes on baking sheet; transfer cookies to wire racks to cool completely.
