位于新斯科舍省的霍尔海港码头是加拿大第一个展示纤维增强聚合物增强、无钢混凝土甲板板概念和光纤监测系统在海洋环境结构中的应用的项目。极端的环境暴露条件使现场成为测试材料性能和传感系统耐久性的绝佳地点。监测计划的早期结果表明，创新结构满足服务水平性能要求。长期耐久性评估仍在继续，并辅以受控的现场和实验室测试项目。光纤传感器的连续远程监测为跟踪结构对环境条件的响应提供了有价值的钢筋应变信息。光纤传感器本身被发现足够坚固，可以承受施工过程和暴露环境；但是，还需要进一步的工作，为某些类型的光纤传感仪器和有关设备建立可行的现场装置。
The Hall's Harbour wharf in Nova Scotia is the first Canadian project to demonstrate the application of fibre reinforced polymer reinforcement, the steel-free concrete deck slab concept and fibre optic monitoring systems to structures in the marine environment. The extreme environmental exposure conditions make the site an excellent location for testing both material performance and sensing system durability. The early results of the monitoring program indicate that the innovative structure is meeting service level performance requirements. Long-term durability assessment is continuing and being complemented by controlled field and laboratory testing programs. Continuous remote monitoring of the fibre optic sensors is producing valuable reinforcement strain information for tracking structural response to ambient conditions. The fibre optic sensors themselves were found to be rugged enough to withstand the construction process and exposure environment; however, further work is required to achieve feasible field units for some types of fibre optic sensing instruments and associated equipment.
