The following section discusses policies of relevance for the use of OPS in the European Union and the United States.
No international requirements for OPS
There are presently no international requirements that would mandate or facilitate the use of OPS. However, National States are free to set standards for berthing vessels. Thus, the CARB has set regulations for ships docking at Californian ports. The use of shoreside power is one of the solutions and ships equipped to receive such power will be able use it.
A comparable case is the exclusion of single-hull tankers by EU and US governments during the nineties, before the IMO agreement.
