• A multi-patch nonsingular isogeometric boundary element method (IGABEM) for 3D problems is presented that provides accurate solutions for multi-patch IGABEM. In order to conveniently implement this method, based on the Greville abscissae, a new collocation method moves the first and the last collocation points of each parametric direction inside of their patches, and a simple method for merging equations handles the extra equations. The numerical results verify the accuracy and efficiency of the present method by comparing it to the conventional IGABEM. •We develop a nonsingular BEM isogeometric analysis formulation.•Its accuracy is demonstrated to be as good as the standard formulations.•A modified set of Greville abscissae are used with a simple method of merging equations that does not adversely affect accuracy.
