  We present algorithms for computing strongly singular and near-singular
surface integrals over curved triangular patches, based on singularity
subtraction, the continuation approach, and transplanted Gauss quadrature. We
demonstrate the accuracy and robustness of our method for quadratic basis
functions and quadratic triangles by integrating it into a boundary element
code and solving several scattering problems in 3D. We also give numerical
evidence that the utilization of curved boundary elements enhances
computational efficiency compared to conventional planar elements.
