Substation Replacement

MSB has been providing engineering for substation maintenance and repairs for more than 40 years and brings extensive resources and experience to the construction of new facilities from the ground up. Working with a leading integrated downstream energy company, MSB managed the facility’s new unit substation replacement program from inception to startup and commissioning.

MSB provided custom-engineered and -designed work packages to meet the needs of the client’s particular infrastructure and construction requirements. MSB delivered a complete engineering package including feasibility and FEED studies; project planning and scoping; equipment specifications andvendor coordination; project management; detailed construction packages and startup support. MSB managed schedules and equipment delivery, as well as supported contractors performing load cutovers and grounding systems, control building, wiring and battery system installation. The new system will reduce outages, increase energy efficiency and lower operating costs at the plant for years to come.

Hazardous Area Classification & Compliance

MSB was tasked with assessing and developing electrical hazardous areas for a process facility containing multiple process flow streams of combustible, flammable and/or volatile hydrocarbons. The hazardous area assessment and revalidation provided development and documentation of classified area boundary limits for the facility to ensure operational safety requirements and minimize the risk of ignition from electrical energy or other heat sources.

MSB engineers’ hazardous area classification and compliance assessment defined the plant’s process pressures, temperatures, flowrates and stream compositions; and verified point source emissions of process equipment such as hydrocarbon pressure vessels, pumps, compressors, piping and pressure relief devices. MSB delivered detailed classified area drawings and documentation, including safety shutdown systems, and class, group and division ratings of temporary and permanent electrical equipment to assure suitability for use in the process areas.

Plant Isolation Switch and MCC Replacement

MSB developed equipment purchase specifications for three 15kV switchgear and three 480V motor control centers (MCC) lineups. MSB then developed a detail design package for the installation of each along with a transition plan of how it could occur during a 4-day planned outage. MSB also provided field support during the planned outage.

Refinery Arc Flash Reduction Program

MSB worked with a Gulf South based oil refinery from project inception to completion including conceptual layout and detailed design. MSB researched available options and their application to the client’s specific equipment. MSB then developed a total installed cost estimate and multiple design packages to implement the appropriate arc flash mitigation option in a staged manner to take advantage of planned system outages.

Pipeline Pump Station

MSB developed electrical equipment purchase specifications for several 12000-18000HP pump stations across a Midwest pipeline system. These specifications were associated with switchgear, transformers, and switchgear building. MSB also developed a detailed design package for the main substation in addition to the pump station power, control, and instrumentation wiring systems. MSB coordinated with the appropriate utility companies to deliver electrical power to the sites on an aggressive schedule.

Arc Flash Analysis

MSB developed an electrical model of the entire refinery electrical distribution system comprised of 230kV, 115kV, 13.8kV, 4.16kV, 2.4kV, and 480V.  MSB performed field work to attain equipment information; developed the engineering model; and, performed fault current, protective device coordination and arc flash analysis.

Electrical System FEED

MSB developed, estimated, and scoped an Front End Engineering Design (FEED) for a complete electrical system including a main substation and seven unit substations involving 230kV, 13.8kV, 4.16kV, and 480V.  MSB created a detailed project plan and schedule to implement the project over 10 years based on facility turnaround schedules.  MSB is currently implementing the first phase of the bid.

Smart MCC and PLC Control System

A Gulf South gas distribution plant hired MSB to develop a PLC based control system to interface to a Smart MCC via Modbus TCP/IP, processing and sending the system information to the natural gas processing plant’s DCS system.  This design created a central location within the control room for operators to view all relevant information from the MCC, such as current motor/pump loading, as well as the ability to control the MCC remotely. The PLC also provided shutdown protection, valve control, and motor control.  MSB Electrical Power Department designed the MCC building, foundations and all interconnects to the existing sub-systems.  MSB Instrumentation and Controls designed and implemented the PLC based control system.
