After drought conditions were experienced across New Zealand in 2019, Watercare determined that the 175 million litres per day (MLD) upgrade to the Waikato River to Redoubt Reservoir (R2R) project should be increased in capacity by including a 50 MLD water treatment plant (WTP) on the Waikato River at a remote location 60 km south of Auckland, New Zealand. Required for urgent drought mitigation, the WTP was designed and commissioned within 12 months, enabling water delivery to Auckland by southern hemisphere Winter 2021. As a conventional pump station could not have been constructed at this remote site within the timeframe, a floating pump station was developed utilising modular Linkflote pontoons to support the equipment, gangways for services and access and tubular piles for restraint. With principal issues of constructability and short programme, the superstructure design incorporated a steel spreader frame to distribute relatively high, concentrated loads over the Linkflote pontoon system.

新西兰怀卡托河每天 6000 万升浮动泵站

2019 年新西兰各地经历干旱后，Watercare 确定，怀卡托河至堡垒水库 (R2R) 项目的 1.75 亿升/日 (MLD) 升级应通过包括一座 50 MLD 水处理厂 (WTP) 来提高容量）位于新西兰奥克兰以南 60 公里的偏远地区怀卡托河上。为了满足紧急缓解干旱的需要，该污水处理厂在 12 个月内设计并投入运行，能够在 2021 年冬季之前将南半球的水输送到奥克兰。由于无法在规定时间内在这个偏远地点建造传统泵站，因此建造了一座浮动泵站开发利用模块化 Linkflote 浮筒来支撑设备、用于服务和通道的舷梯以及用于约束的管桩。
