Siemens MMDC, Main Motors and Drives Contractor, a Unique Business Concept for Cost Reduction, Efficiency, and Transparency for Oil and Gas Projects

The MMDC business concept was developed in close collaboration with the oil and gas industry to address the highest requirements for efficiency and reliability. Prerequisite for this business concept is a comprehensive portfolio in motors and drives. Furthermore it offers close coordination between end user, EPC (Engineering-Procurement-Construction), OEM (Original Equipment Manufacturer), and Siemens – throughout all project phases and the entire lifecycle.

MMDC makes engineering and project management much simpler for all global partners involved in the project, and it leads to a shorter overall project time.

MMDC is based on the comprehensive range of products and services that only Siemens can provide on a global scale. It includes motors, drives, generators, and couplings. The range of services covers the entire plant lifecycle and can be matched to any project’s requirements. In addition, Siemens performs all important tests, such as back-to-back tests, in an in-house test center. Processes and portfolio comply with all national and international standards and regulations. The comprehensive range of products and services enables only Siemens to offer the MMDC benefits to clients.

Optimized time frame and faster start-up

As MMDC, Siemens supports the customer throughout the entire project – from the FEED phase all the way to operation. Close cooperation during the FEED phase results in the definition of the exact scope and specification of any required equipment. The Siemens MMDC project organization as a single point of contact is responsible for the successful implementation throughout all project phases.

The MMDC project organization compiles all information and requirements from the FEED phase into the Motors & Drives Project Catalog. It is the core element of all phases that follow and ensures that engineering and procurement as well as construction and commissioning are easier to handle. This means that it takes considerably less time until operation can start. During operation, the MMDC concept contributes to reduced OPEX in many ways. The Motors & Drives Project Catalog also serves as a reference for maintenance and services as well as for future projects.

In the earliest stages of a project Siemens establish a FEED support team that develops standards resulting in the Motors & Drives Project Catalog. All cost savings will be identified during this process, which contributes to an optimized total cost of ownership. All technical and commercial requirements of the project are clarified and documented. The MMDC project manager and the global capture team ensure that interfaces are reduced to a minimum. The MMDC Motors & Drives Catalog includes the scope of motors and drives as a mechanical equipment list and an electrical load list. There are also harmonized design typical for motors, drives, gearboxes, and couplings as well as testing and documentation standards for the entire range of motors and drives. The MMDC Motors & Drives Catalog also specifies predefined terms and conditions for purchases including a global price list. All these components and information are compiled in the Motors & Drives Project Catalog, which is a binding document for all parties involved. It is the core element of all following project phases. Plus, parts of it can be used in future projects and make them even more cost-efficient.

In the engineering and procurement phase, the Siemens MMDC project team provides global offer and order tracking services. The EPC can rely on a comprehensive overview regarding all offers and orders from the OEMs and Siemens. Project reporting ensures the highest possible degree of transparency for the entire project schedule and facilitates its monitoring. The sophisticated MMDC channel management provides high flexibility to react efficiently on changes of the project schedule. All these benefits contribute noticeably to reducing the effort that is required for engineering and procurement. This means that the expenditure of time and cost is also kept at a minimum.

The coordination efforts in the FEED phase also have an positive impact on construction and commissioning. In this way MMDC simplifies the installation and commissioning work. The standardized equipment allows for optimized training of the commissioning and operational staff. Plus, the local Siemens project organization provides fast and consistent support at any time. The single vendor aspect of the MMDC business concept increases safety by reducing the number of contractors on site.

The MMDC business concept has obvious advantages for end users during the operation phase. They can rely on MRO (maintenance, repair, and operation) support from a single supplier and benefit from a contact that is familiar with the project. This facilitates intelligent spare parts management and ensures an optimized maintenance schedule as well as tailored support from the local Siemens entity. As a perfect add-on to MMDC, an optional comprehensive condition monitoring system minimizes the risk of unscheduled downtimes and increases the availability of the plant. Based on the results of the continuous monitoring, improvements can easily be implemented to products and processes. Siemens can provide the service for all motors, drives, gears, and couplings as the single service partner. This helps increase operational safety and plant availability in line with the end customer’s health, safety, and environment (HSE) policy.

MMDC at a glance

With MMDC, Siemens has introduced a business concept that is based on a unique and comprehensive portfolio. It starts in the earliest stages of a project and is a solid basis for all ensuing phases. The Motors & Drives Project Catalog is the core element and ensures a standardized scope of supply as well as efficient processes throughout the entire project lifecycle. All parties involved in the project benefit from its obvious advantages. It can be reused in future projects and thus provide even more benefits. The consistent tracking of offers and orders makes a complex project completely transparent from day one and ensures that the schedule is always maintained. The MMDC business concept also optimizes all deliveries for minimum on-site logistics and a high level of safety throughout the entire construction and commissioning phase. Optimized operational and maintenance processes ensure that the plant operates at highest efficiency and availability levels at all times. Siemens’ experience from successfully completed MMDC projects shows that the MMDC concept allows for cost savings up to 15 percent. Conclusion: The MMDC business concept, which is uniquely available from Siemens makes a noticeable contribution to cost reduction, standardization, efficiency, and transparency in projects of the oil and gas industry worldwide.
