Piet Brouwer Electrotechnology

Piet Brouwer Electrotechnology started designing and installing electrical systems on fishing trawlers in the former island of Urk back in 1961. Because the fishermen and crew on these trawlers were, and still are, family and friends, and because the North Sea is notorious for its rough seas, the company has always had a personal interest in making sure its electrical systems continue to operate whatever the weather.<img alt="" src="https://syt-store-production.s3.eu-west-1.amazonaws.com/photo/143394/image/large-9b77dd6b4ad355e5ea46ce66ac6267c0.jpg" data-gid="gid://syiq/Photo/143394">During the last quarter, no less than three superyachts have been deliverd by Piet Brouwer Electrotechnology with all the on-board electrical, navigation, and entertainment systems.Piet Brouwer Electrotechnology fitted the entire electrical systems for the superyachts Lady Dee, a 47 metre long motor yacht, the Nassima (Acico Yachts), a 49 metre long motor yacht, and a 46 metre long motor yacht built by Vicem Yachts in Turkey. The cutting‐edge technology installed by Piet Brouwer Electrotechnology on-board these yachts included an Active Harmonic Filter (AHF), which delivers a stable on-board power supply that eliminates all harmonic interference and guarantees maximum operational comfort on-board. Another example is the crossover box, which improves the user-friendliness and operational reliability on-board for the engineers.<img alt="" src="https://syt-store-production.s3.eu-west-1.amazonaws.com/photo/143395/image/large-a79356852ee55d7986d634c8ddbc7ed9.jpg" data-gid="gid://syiq/Photo/143395">A subsidiary of Piet Brouwer Electrotechnology, Marble Automation, supplied the monitoring and control systems on-board these three yachts. The superyachts Nassima and Lady Dee were also fitted with a Marble Automation alarm system. The alarm schematics are displayed on Hatteland monitors, which also show the status of the integrated General Alarm. In addition, a Marble Automation tank content measurement system was also fitted in the yachts. Because the tank tables can be fully imported into the Marble Automation system, a very accurate reading can be obtained for the tank content. The precise location of the tank is indicated on a diagram of the yacht in the control panel.<img alt="" src="https://syt-store-production.s3.eu-west-1.amazonaws.com/photo/143396/image/large-174bf69778fe2b05a5314ce14526a1ef.jpg" data-gid="gid://syiq/Photo/143396">The Marble Automation control panel can also be used to operate the pumps and to check the current status of the batteries. This information is displayed in a way that is designed to enhance operational simplicity. A diagram showing the location of the watertight doors and windows can also be displayed on the control panel in the bridge of the yachts. Another additional feature that can be accessed with the bridge monitor is the position and status of all navigation lighting. The alarm systems on the motor yachts Nassima and Lady Dee are displayed using a separate screen in the mess room. This ensures the crew can take action immediately whenever necessary. Finally, the fire alarm system is linked to the Marble Automation system via Modbus, which gives a clear overview of the fire alarms in a diagram of the yacht.<img alt="" src="https://syt-store-production.s3.eu-west-1.amazonaws.com/photo/143397/image/large-d026a29918313f5f7b8812e9cd09c9f9.jpg" data-gid="gid://syiq/Photo/143397">The portfolio of superyachts that have been fitted with the electrical systems of Piet Brouwer Electrotechnology and the monitoring systems of Marble Automation has grown exponentially in recent years. Negotiations are currently on-going with various yacht builders for the installation of similar systems on-board other sail yachts and motor yachts.Piet Brouwer Electrotechnology +31 0527 681 651 <a href="mailto:info@pietbrouwer.nl?subject=Piet%20Brouwer%20Electrotechnology%20on%20SuperYachtTimes.com">info@pietbrouwer.nl</a> <a href="http://www.pietbrouwer.nl" target="_blank">www.pietbrouwer.nl</a>

Three superyachts delivered with systems by Piet Brouwer Electrotechnology

Photo of Berzinc by Fred Meijer Piet Brouwer Electrotechnology has recently adapted and fitted the main switchboard of the 42 metre superyacht Berzinc with a new power management system. The brief was to ‘keep it simple’. <img alt="" src="https://syt-store-production.s3.eu-west-1.amazonaws.com/photo/140524/image/large-528c18bf831b1ddfa8d5264349600157.jpg" data-gid="gid://syiq/Photo/140524"> <img alt="" src="https://syt-store-production.s3.eu-west-1.amazonaws.com/photo/140525/image/large-13a97e64db9fcc208d8346567a93b00b.jpg" data-gid="gid://syiq/Photo/140525">As the electric sternthruster had been removed from the yacht, it was possible to considerably simplify the switchboard. Additionally, the power management system could be reduced to the most essential functions, making it more user-friendly as well as easier to maintain, and ensuring that the chance of failure is negligible. All in all, this impressive adaptation by the engineers of Piet Brouwer Elektrotechniek has enhanced the system’s reliability and, therefore, the overall safety onboard.

New power management system for superyacht Berzinc 

The quality of the power available onboard yachts has never been more important. Thanks to the modern rectifier technology used in motor drives, UPS systems, battery charging stations, light dimmers and computers, a significant improvement in comfort levels has been attained. At the same time, however, these modern technologies have an impact on harmonic distortion in the electrical distribution circuits onboard. Tackling this issue requires a specialist approach. <img alt="" src="https://syt-store-production.s3.eu-west-1.amazonaws.com/photo/139185/image/large-925389a155a87c53dfb3e896b1728e2c.jpg" data-gid="gid://syiq/Photo/139185">“Any increase in harmonic distortion will have an influence on sensitive equipment,” explains Henk Brouwer, managing director of Piet Brouwer Electrotechnology in the Netherlands. “By increasing comfort levels you run the risk of reducing the reliability of the electrical circuits. To ensure an energy efficient and reliable electrical circuit, we use an Active Harmonic Filter (AHF) to improve and stabilise the power quality on board.” By using an AHF, the harmonic distortion created by all the different loads on board is compensated. This filters the harmonics, ensuring a consistent and stable electrical system. And in addition to enhancing reliability, losses due to harmonics are reduced to a minimum. <img alt="" src="https://syt-store-production.s3.eu-west-1.amazonaws.com/photo/139186/image/large-0e3efe1de71490597cde8c5f042eb57e.jpg" data-gid="gid://syiq/Photo/139186">By enabling the load balancing function, the three phases of the generators onboard are continuously equally loaded. In combination with the power factor improvement, this results in an optimal use of the generator capacity and lower fuel consumption. Piet Brouwer Electrotechnology advises all clients to install an Active Harmonic Filter as standard onboard yachts. The company is currently fitting systems on several projects worldwide. These include the 49-metre MY Nassima and the 47-metre Lady Dee, both under construction at Acico yachts in the Netherlands.
