The true value of marine civil engineering
─ A new paradigm of ocean utilization connecting coastal, offshore, and deep-sea frontiers ─
Japan’s marine utilization and marine civil engineering have evolved through three stages:
port/logistics infrastructure development, spatial expansion, and environmental symbiosis/
multi-functional utilization.
Amid urgent climate and energy demands, marine civil engineering is expanding into
offshore and deep-sea frontiers, driving a significant paradigm shift.
This feature issue explores this evolution across three core themes: overarching ocean policies,
cutting-edge technical practices, and workforce development.
In the policy section, we outline strategic directions based on the "Basic Plan on Ocean Policy"
and review the history of ocean development, before presenting a Japan-Singapore dialogue on
port strategies.
For technical practices, we highlight Calcia-modified soil for seaweed beds,
recreational fishing models, advanced underwater backhoes, driverless construction for tidal turbines,
commercial floating wind, and deep-sea mining.
Finally, to focus on the people supporting marine civil engineering at the forefront, we introduce
workforce development at Taneichi High School, Japan's only school seamlessly teaching both
diving and civil engineering.
This issue highlights how marine civil engineering contributes to
sustainable development, carbon neutrality, and Japan's future as an ocean nation.
