MPE, together with our experienced offshore fabrication partners, can produce a preliminary design of an offshore substation (electrical, topside, jacket) including rating of equipment and budget estimates.
The design produced is suitable for tender specifications. We can also provide construction supervision to ensure equipment is supplied and installed to specification.

Whether the purpose is for grid code compliance, offshore wind farm export cable compensation, voltage stability improvement, system wide reactive power reserve planning, MPE can appropriately size and specify your reactive dynamic and static reactive power equipment in the most economic way possible while ensuring requirements and voltage stability margins are met.

MPE can assess your project to determine if ​harmonic filtering is required. If so, we can design active or static filtering solutions to mitigate harmonic current emission or resonance issues.
We can develop concept designs, or detailed filter design including specification of individual filter components considering tolerance for frequency and voltage variation, to a level of detail suitable for tender.

A good equipment specification is important to ensure that you get the most cost-effective equipment for your application with no ‘surprises’ after it is received.
Our philosophy to achieve this is to provide specifications that are clear and concise, providing enough information and requirements to ensure that equipment is suitable for the application while not placing unnecessary restrictions on the vendors which can increase costs without providing any tangible benefit.

Following specifying the equipment for your site, MPE can then help you to choose the relevant winner of each package

MPE can route and select cables for your application based on technical requirements and cost impact of CAPEX and OPEX of the system. This can range from checking cable ampacity, voltage drop and short-circuit withstand to ensure compliance with applicable codes, through to optimisation of cable sizes based on installed cost, annualised losses for time-varying loads, and calculation of net present value of losses (OPEX) vs. CAPEX.

MPE can act as an owner's engineer, providing independent advice and expertise to ensure the success of your project.
We have a particular specialization in acting as the owner's engineer for renewable energy projects.

Throughout the construction process, MPE can provide on-site support and supervision. Including:

Power systems must remain stable for a variety of disturbances, considering a wide range of dynamic responses for different equipment and system configurations. MPE can perform dynamic studies to assess the stability of any network. Our services include:

The results of the EMT studies can be used in insulation coordination procedures to define minimum insulation requirements for equipment, or to design mitigation measures such as surge arresters and sheath voltage limiters. These are designed in accordance with international standards such as IEC 60071 and IEEE C62.82.2.
We also specialise in circuit breaker transient recovery voltage (TRV) simulations to assess circuit breaker dielectric capabilities, and designing the most cost effective mitigation measures where required.
One area of particular expertise for MPE is with transient studies for HVAC connected offshore wind farms with long export cables (up to and in excess of 200 km and 275 kV), and array networks with voltages up to 66 kV.

Harmonics in power systems can cause overvoltages, excessive heating of equipment, mal-operation of equipment, and poor power quality for end-users. Our comprehensive study approach considers different system configurations, equipment outages, harmonic voltage gain factors / transfer coefficients, and harmonic impedance loci or full harmonic network models. MPE offers a suite of services including:

For any size of wind farm, at any distance from shore, MPE can produce a preliminary design of the entire HVAC or HVDC grid connection of your offshore wind farm including:
