The paper presents certain results devoted to the essential norms and norms of singular integral operators in spaces with weights. It is found that these rules in the case of Lyapunov-type contour on portions essentially also on the contour. The values of the essential norms are used to determine noetherian conditions for the characteristic single operators with measurable and marginal coefficients.
