Study on Considerations in Design Work for the Reformation

of Existing Port Facilities

Protective and Mooring Facilities in Port Areas

Hisachika TAKANOMasafumi MIYATAAtsushi FUJIIShigeru IYAMAEma KATOToru YAMAJIKenji SAKATA

Synopsis

In recent years, it is required to reorganize or improve port functions effectively by utilizing existing

facilities in port areas for the future development and efficient use of ports. This leads to a rapid increase in

structural design work for the reformation of existing port facilities, such as strengthening its original

structure and converting a facility from its original purpose to another. However, references are very

limited for such design works.

This study is intended to summarize key considerations in design work for the reformation of existing port

facilities, based on past design cases (recent 16years) of protective and mooring facilities in port areas. As

the key considerations, the following items are summarized: classification basis of the purpose of

reformation design, main construction methods for reformation, and main issues inherent in reformation

design that need to be carefully considered. In addition, representative examples of the past reformation

design cases are provided in the appendix as references for effective design work of reformation.

Key Words : existing port facility, reformation, protective facility for harbor, mooring facility, reformation design
