1.0 INTRODUCTION

The CG is performing routine dry dock maintenance on a 45 RB-M in Boston, MA at an organic shipyard facility. Unusually high corrosion in the port and starboard intake tunnels of the water jet will require clad welding by the organic shipyard to regain the proper thickness of the hull within the tunnel. A vendor is required to perform machining inside the intake tunnels for the water jet propulsion systems at the flange where the impeller house connects to the water jet inlet and transom flange lip. All work will be performed IAW the below references:
