It is a familiar problem: The generator starter batteries are empty and the engineer only
discovers this fact when trying to start the diesel engine. At such moments there is very little
time to carry out the activities required to get the generator set started. Engineers normally
therefore try to start the diesel engine involved using loose starter cables linked to the starter
battery set from another diesel engine than the affected generator. To avoid having to carry out
such a time consuming solution, Piet Brouwer Electrotechnology recommends installing a
crossover box onboard superyachts, as project engineer Hessel Bakker explains.


“Using key switches it becomes easy to start one generator battery via another diesel engine and
vice versa without requiring loose cables. Additionally, a battery monitor is connected to the
battery charger and all individual batteries. Whenever a fuse or battery charger fails or batteries
need replacing, an alarm goes off, warning the engineer and ensuring that he is able to start the
generators and keep the onboard network working properly.”


Piet Brouwer Electrotechnology has installed crossover boxes on various projects, including a 46-
metre yacht built by Vicem Yachts in Turkey. This vessel is part of the so-called ‘Vulcan Line’ with
which the yard hopes to enter the superyacht market. In addition to the 46-metre yacht, Vicem is
also building a 35-metre Tri-deck and a 32-metre Raised Pilot House. The yachts were developed
with various partners from the superyacht sector, including designer Frank Mulder and interior
design studio Art-Line. Vicem Yachts selected Piet Brouwer Electrotechnology as supplier for the
entire electrical system based on the company’s wide experience in the superyacht market and
the reliability of its installations.
