With the worldwide emphasis on energy transition and water resource, the majority of new marine pipeline schemes are coming from the development of new desalination plants, power plants (CCGT), LNG refineries and Industrial developments. For coastal locations, all of these require the intake and discharge of large volumes of seawater for cooling and process. There are many challenges and influencing factors that have to be considered for the design and construction of intakes and outfall for these projects. This can include the choice of pipe material, installation method, diffuser and intake head configurations, hydraulic performance, environmental and water quality requirements to name a few. The solutions to these challenges often vary depending on the location, process, environmental and engineering constraints. No two projects are ever the same. Often the intakes and outfalls are not considered as key priority elements of a projects delivery, however they are essential for completion and operation of the plant and require early development in the project delivery. This paper presents the challenges that designers and contractors face with marine pipeline systems, how they can be overcome based on case studies of projects completed by RHDHV globally and how these can be applied to the Asia Pacific markets. The solutions, whilst employed frequently in the European and Middle East markets, are considered to be relatively new to the Asia Pacific Market and a better understanding of these would be beneficial.
