Perforated seawalls are designed to calm down the turbulent waves in Victoria Harbour of Hong Kong. Most accounts are given to hydraulic performance and structural issues to minimize the wave reflection and enhance the structural stability. With an ever-increasing array of environmental laws, regulations and requirements, more efforts are made to maintain the compliance. Therefore, a perforated seawall must provide a safe and healthful environment for the personnel working on and around it. Experience has shown that the establishments on environmental and safety considerations at a design stage can offer significant benefits to the consequent operations and maintenance. Early planning can make compliance with legal and technical requirements achievable without unnecessary cost and/or schedule impacts. As a standard procedure to the establishment of an environmental management system (EMS), environmental aspects are identified first and then evaluated. Considerations cover over-topping, noise, water circulation, and floating debris. This work can be considered as a technical guidance for the eco-design of perforated seawalls.
