The original build included PILGRIM’s Morgrip coupling bolts and in 2018 the USNS Pomeroy came into drydock for maintenance. After some complications with the Morgrip Bolts PILGRIM proposed to PATRIOT (ship management company) and the U.S. NAVY the advantages of upgrading to PILGRIM’s Radial Fit Bolts, the decision was made to switch the whole class of ships over to Radial Fit Bolts due to the tangible benefits even when considering the replacement costs.
