We propose a modification of collocation methods extending the 'averaged vector field method' to high order. These new integrators exactly preserve energy for Hamiltonian systems, are of arbitrarily high order, and fall into the class of B-series integrators. We discuss their symmetry and conjugate-symplecticity, and we compare them to energy- preserving composition methods. c 2010 European Society of Computational Methods in Sciences and Engineering
