To facilitate the expansion of offshore wind energy, it is imperative to proactively secure installation vessels and the supporting infrastructure of marshalling ports. However, Mokpo New Port is currently the only domestic facility practically capable of executing installation operations. Consequently, there is a significant risk that port bottlenecks will materialize as deployment volumes scale up in the future. The critical challenge is that while the development of marshalling ports requires passing the Preliminary Feasibility Study (PFS) in a timely manner,
the current port PFS framework may not fully reflect the roles and operational characteristics of marshalling ports in benefit calculations, which could lead to an inappropriate assessment of their economic feasibility.
Accordingly, this issue paper reviews the current port PFS Guidelines from the perspective of offshore wind marshalling ports as ‘special-purpose infrastructure’ and proposes directions for regulatory improvement to ensure realistic benefit quantification.
