About this file
This document is a Performance Work Statement (PWS) or technical specification detailing modifications to existing 2-inch waste drain piping systems at multiple locations on a vessel. The work involves cold cutting existing pipes and installing carbon steel flanges to create removable piping sections for maintenance access and cleanout capabilities.
The work is divided into multiple tasks: Task A requires modifications to two 2-inch waste drain pipes in the Port side EOS A/C compartment (3-66-02), involving installation of four 2-inch carbon steel flanges on the outboard pipe to allow a removable spool, and two flanges with a nipple and cap on the inboard GW pipe for cleanout access, plus connection to an inboard overboard pipe using a 2-inch Y fitting with gaskets and hardware. Task D specifies cold cutting a 2-inch waste drain pipe in the Upper Shop (3-70-1) with installation of two 2-inch 150# carbon steel socket welded flanges to fabricate removable piping sections, including gaskets and hardware. Task E involves cold cutting 2-inch waste drain piping from compartment 3-72-3 (joiner door to overhead crane controller) with installation of eight 2-inch 150# carbon steel socket welded flanges to create multiple removable piping sections, with gaskets and hardware installed throughout. All tasks require proper sealing and hardware installation to maintain system integrity.
