Nearly strongly singular and hypersingular integrals in 2-D boundary element method are treated by modified Gauss-Chebyshev quadrature formula. The weak nearly logarithmic singularity is extracted and integrated analytically. The proposed technique is tested in several numerical examples. Some proposals are given for an extension of the approach to 3-D calculations.
