Project Overview

The client requested a series of Tank MOV Replacement projects at various sites through their system. Deliverables included P&IDs, scope of work drawings, datasheets, isometrics, as-builts, wiring diagrams, and material requisitions. Rally provided procurement support, engineering checks and authentication of drawing packages, as well as a thorough review of all vendor documents.

Tank MOV Replacements main

Replacing Valves

Rally is replacing a 24” actuated wedge gate valve with a 24” actuated triple offset valve. The scope entails providing engineered drawings to allow the client to change the valve without any piping modifications. Electrical engineering will check the existing system with the plan to reuse all the existing equipment and cables.

Inspections & Detailed Engineering

During the clients 20-year inspection outage, they are replacing multiple motor operated valves (MOVs) with new valves and actuators. The NPS 24, 20 and 16 gate valves are replaced with new triple offset valves and actuator with the same face to face dimensions. Where the new face to face dimension cannot be achieved, Rally is designing piping changes that are simple for the client to install.

The client has requested detail engineering services from Rally for the removal of NPS 24 motor operating valve (MOV) and replacement of NPS 16 manual valve including spool pieces. Included in the scope is final vendor data book and as-built client red-line drawings.
