See the link for this example:

"The orientation of the port entrance and the outer protective works such as breakwaters and jetties, are designed to provide the maximum protection of the basin and the berthing quays from waves, while maintaining sufficient width for the safe passage for the design vessel(s)."

This seems to fit your source, as well as this from Section 6 a of Havneloven:

"En havn kan uanset organisationsform
1) forestå drift og anlæg af havneinfrastruktur, herunder af dækkende værker, kajer og havnebassiner,"
