AI Contract Overview

This emergency project for the Pearl Harbor Naval Shipyard involves the in-kind replacement of main drain pumps 3 and 4 in Drydock No. 2 after both units seized during operations. The scope of work includes the removal of existing pumps and motors, installation of new replacements, and all necessary electrical work and appurtenances. Additionally, the contractor may be required to perform concrete foundation work, leak checks, alignment checks, and operational testing to ensure the system is fully functional. The project is critical for maintaining safety compliance with MIL-STD-1625, which requires at least two operational drainage pumps to protect U.S. Navy ships from flooding while in graving dock. Beyond the pump replacements, the contract includes the relocation and replacement of two stilling wells and new transducers for automatic pump operation, as the original equipment was significantly damaged during an undocking evolution in October 2023. This effort is managed by Navfac Hawaii under NAICS code 237990.

Full Description

This is considered an emergency project. Due to the urgency of this project, Pearl Harbor Naval Shipyard (PHNSY) is requesting to replace in kind two Drydock No. 2 main drain pumps, drain pumps #3 and #4 that seized during pumping operations. The scope shall involve removing the existing main drain pumps and motors, replacing them in kind and shall include all electrical work and appurtenances necessary to get the drain pumps operational. Work may involve concrete foundation work at the base of the pumps. Other incidental work shall include leak checks, alignment checks, resetting all parameters and operational testing. MIL-STD-1625, Safety Certification Program for Drydocking Facilities and Shipbuilding Ways for U.S. Navy Ships states that there shall be at least two drainage pumps available wherever a U.S. Navy ship is in graving dock and that each drainage pump alone shall have sufficient capacity for the removal of drainage water. The two drainage pumps serves to isolate the Navy ship by two methods of protection from all potential flooding sources, such as flooding and dewatering systems. The main drain pumps are therefore critical components of the drydock system. The drainage pumps maintain the dry dock floor dry by pumping out the ground and sea water that seeps into the dock through numerous cracks and vertical construction joints on the walls into the drainage system. Amendment A: In addition to replacing the damaged drain pumps, need to include the relocation and replacement of 2 existing stilling wells with new transducers for the automatic operation of the drain pumps. The stilling wells were significantly damaged during the 12 OCT 2023 undocking evolution, where the flooding and dewatering of the dry dock caused the stilling wells to be dislodged from their mounted locations and damaging the tra ...
