The Seaport IJmuiden required a solution to provide electricity to trawlers during their stay in the port, in order to prevent noise disturbance and vibrations, as well as to reduce emissions.
Royal HaskoningDHV was initially appointed for the preparation of a conceptual design of the Cold Ironing (shore power) system and an economic feasibility study was carried out. Following this work, we also produced the technical tender documents which were the basis for Contractors to submit their bids for the project execution. During the construction phase, Royal HaskoningDHV acted as design and site supervisor for all electrical works.
In total, 6 connection points for shore power were built, each capable of providing a maximum of 250kVA power to the connected ships. The system became operational in July 2015 and can provide electricity both at 50Hz and 60Hz frequency for each connection point, with a maximum of 4 ships able to connect simultaneously. More and more fish trawlers are being adapted to ensure that they are able to connect to the system moving forward.
The benefits of having such a system in place are threefold. Not only does this technology equal cleaner air and reduced emissions for the port, it also creates a better perception of the port as a ‘good neighbour’. Secondly, shipping companies now have lower fuel costs in port and less maintenance costs on auxiliary engines in the long term.
When designing the ship connections, we took into account measures to avoid errors through the use of mechanical interlock systems to prevent the disconnection of cables while parts of the system are live. This is a measure that is required to guarantee safe system operation, even in case the system is operated by people without specific electrical know-how. The shore power system design was completed in compliance with all relevant Dutch and international standards, including NEN1010 and IEC80005-3.
