The biggest changes made at the Port of Kapellskär during the rebuilding work has been the construction of a new pier with two new quay-berths and the expansion of the port esplanade area.
Kapellskär had four quay-berths that were built in the 1960s and 1980s. The two oldest quay-berths needed to be either renovated or entirely rebuilt. As vessel sizes are increasing, both lengthwise and in draught, Ports of Stockholm elected to build an entirely new pier at the southern end of the port. The new port also has improved safety and the space available for the vessels to manoeuvre.
Larger esplanade area
The design of traffic flow at the port was not optimal for the efficient management of the number of vehicles that arrive at the Port of Kapellskär. By expanding the port esplanade area more efficient traffic solutions were introduced and the loading and unloading of vessels has become more efficient.
To provide a modern port with electricity, which also includes onshore power supply for vessels in port, the electricity company Vattenfall needed to improve the electricity network supplying the port. As a first step in this process the port has already allowed a high voltage electricity sub-station to be built at the port.
Vessels in port must be provided with fresh water. Water at the port was previously provided by the port's own well, which had a very limited capacity. For that reason Ports of Stockholm signed an agreement with the Municipality of Norrtälje to construct conduits to connect the Port of Kapellskär to the municipal water supply.
Managing waste water
A modern port should also offer black and grey water management facilities for vessels in port. Each of the quay-berths in the reconstructed port are connected to a new waste water management facility and this allow the vessels in port to offload their black and grey water. This waste water management facility will not only process sewage from the Port of Kapellskär, but will also serve most of Rådmansö island.
Development of the Swedish Maritime Administration
A small area of the port that was affected by the reconstruction work houses a Pilot Station owned by the Swedish Maritime Administration.
