More than a decade ago we supplied our advanced medium frequency drive systems to our French customer, who is active in uranium enrichment. Since then we have been doing the level 1-4 maintenance on these drive systems as well. Because the electronics in the drive systems are getting older now, we have recently set up a more pro-active approach for these drives. Within this pro-active Risk Based Asset Management approach, we have developed the so-called VONK Life Cycle Management (LCM) programme, for which we were recently granted a six years contract by our French customer.

The VONK LCM programme comprises of the following main components, each with their specific added value for the customer:

Obsolescence management – by continuously monitoring the potential obsolescence, the customer will know at an early stage which components will become obsolete and whether they can be replaced by an alternative or need to be re-designed,

Knowledge retainment – we will make sure that the necessary knowledge will stay available at the right level and within sufficient resources,

Keeping Technical Product Documentation (TPD) up-to-date,

Maintenance of customer-specific electronics test facilities,

Managing all security sensitive data and documentation storage, including security screening of employees.

Are you interested in the possibilities of Life Cycle Management for your power and electronics related installed base as well, please contact us to find out together how we can create value for you.

VONK receives recognition award as part of the integrated team for the SCOT Digitalization and Automation Journey

VONK has recently been recognized in supporting our client Brunei Shell Petroleum (BSP) in further developing the digitization and automation of the Seria crude oil terminal.

As part of an integrated team including Operations, Maintenance, Engineering and our local partner Zainal Daud , an end to end solutions approach was used to deliver solutions to complex challenges.

Using an end to end solutions approach allowed for the multi-discipline team to collaborate in the development, implementation and handover of cost effective reliable solutions.

Opportunities were identified  and solutions delivered in an extremely short time frame using a shared focus, goal driven approach.

The digitization and further automation has already had multiple successes and shown an asset that is fit for the future.

Congratulations to the BSP and VONK Brunei Team members for this joint recognition on the Wall of Pride.

VONK finished  the  engineering of  the substation and in the coming weeks the outfitting and testing of this prefabricated VFD substation will be started. This substation consists of 3 segments, which willbe transported separately to the final location of the Assa North project in Nigeria.

Being a specialist in power conversion, control and automation and electrical distribution, VONK is your ideal partner when it comes to the design and construction of prefabricated modules, like E-Houses, Substations, Control Rooms and Instrumentation Buildings. We have decades of experience with containerized modules and have built up an excellent reputation for innovative ideas and designs, quality products and reliable delivery.

The subject modules in this Assa North project will be equipped with:

  • medium voltage switchgear
  • 400VAC power distribution systems
  • large back-up battery storage system, including its distribution system
  • substation’s control and monitoring systems (SMCS).

The work is progressing according to plan and we thank all our supply chain partners that contribute to make it happen.

Our commissioning team is about to be mobilized to prepare the factory acceptance test (FAT), which is scheduled to commence in August. 

This morning our colleague Dave Oesterholt held an interesting webinar presentation on “Pre-fabricated Buildings for Electrical and Control Systems”. A great audience, reaching from OEM and EPC to end user, network operator and asset owner, divided over more than 12 countries, attended the 30 minutes session, followed by a questions round.

The entire presentation including questions round is now available for you via the following YouTube link: https://youtu.be/juSoWShuhMQ

VONK has delivered Prefabricated Substations, Control Rooms, Field Auxiliary Rooms, Local Equipment Rooms, Hybrid Power Systems etc. all over the world already for many decades. The plug-and-play prefabricated buildings can play an important role in the Energy Transition too, as they can be used for many applications, like Green Hydrogen production systems, Battery Energy Storage Systems, Power Generation, Power Distribution or Control Units.

In this webinar, VONK has presented the features, benefits, design aspects and use cases of pre-fabricated buildings, and how you can reduce your overall costs compared to building in-situ, on site.

We hope you will enjoy looking back this webinar and we look forward to seeing you online for one of our next webinars, which we will plan in the near future.

As VONK we are proud to announce the upcoming deliveries of two power supplies for the Hydrohub test facility at the EnTranCe site in the city of Groningen, the Netherlands. The Hydrohub MegaWatt Test Centre is set up as a state-of-the-art facility for optimizing and scaling up electrolysis for green hydrogen production. The facility is key to perform research for large scale electrolyser systems. The project is coordinated by the Institute for Sustainable Process Technology (ISPT) with the Hydrohub MegaWatt Test Center consortium.  

In such a landmark project, it is logical to have a leading company like Vonk involved for the power supplies. For large scale electrolysis facilities the power supply is a key component with regards to ROI and CAPEX costof the total system. The fundamental and application knowledge of Vonk on power conversion leads to optimized solutions which are based on standard building blocks. Because ROI is driven by power quality and efficiency and CAPEX by component costs, Vonk’s optimized solutions will give the best outcome for any large scale electrolysis project.

The projects that VONK carries out for BVI Electricity Corp (BVIEC) go back to the early years of this century. For a number of years, the cooperation has been further intensified and this has resulted, among other things, in a multi-year maintenance contract.

Since the outbreak of the Covid-19 pandemic, VONK has remained in close contact with the BVIEC and the British Virgin Islands Government to continue exploring options for on-site operations. After obtaining a special exception visa and the mandatory quarantine periods, a team from VONK traveled to the BVI again at the end of August 2020 to complete the installation and commissioning of the new 208V and 480V low voltage distributors we supplied.

Subsequently, we successfully carried out the first PLC replacement on one of the 4 diesel generators under the same difficult travel conditions. The new PLC hardware and software upgrade had already been delivered by us in 2019/2020 but could not be carried out earlier due to the pandemic. The PLC conversion of the last three diesel generators is planned for the coming months. We demonstrate the maximum flexibility by having these activities run synchronously with the maintenance of the diesel generators, so that maximum availability of electricity to be supplied to the country remains at all times.

Assa North F.A.T. started earlier this week.

It has been months of hard work to get the substation for the Assa North project ready for its final acceptance test.

The factory acceptance test commenced earlier this week. Due to the COVID-19 pandemic, a small team of SPDC is present, while the other were unable to travel to the outfitting facilities. Therefore, the factory acceptance test is carried out virtually.

The prefabricated walk-in substations house medium voltage (MV) and low voltage (LV) switchgear as well as auxiliary equipment to power the various production skids at client’s facility in Nigeria. The substations will be shipped to the site as soon as the test have been completed.

Thanks to all who have contributed and for the great work done so far.
