Semigroups of order-preserving transformations have been extensively studied for finite chains. We study the monoid OP_N of all order-preserving partial transformations on the set N of natural numbers, where the partial order is a fence (also called zigzag poset). The monoid OP_N is not regular. In this paper, we determine particular maximal regular subsemigroups of OP_N and show that OP_N has infinitely many maximal regular subsemigroups
