Abstract

The Ocean Observation Systems (OOS) group of the National Institute of Ocean Technology (NIOT) is involved in the design, development and sustenance of moored data buoys in the Indian Seas. The moored buoy systems deployed in the Northern Indian Ocean provide real-time, continuous observation of surface meteorological and oceanographic parameters which help in monitoring extreme weather events and natural disasters such as cyclones and tsunamis. Buoy components are of different sizes and shapes and are made of various materials, including metals and plastics. However, due to unique and critical design requirements, the development of deep-sea components faces hurdles caused by manufacturing limitations. The advent of additive manufacturing (AM) has met the demand for quickly producing parts. Due to the high pressure and low temperature conditions, it is extremely difficult to design and develop deep sea components. Consequently, High Impact Polystyrene (HIPS) material has been selected for the subsurface floats. The float is manufactured using the Fused Deposition Modeling (FDM) additive manufacturing technique in the Fabheads 1K FDM printer with pellet based extrusion method. These subsurface floats are used at a water depth of 500 m in NIOT buoy systems, with a working pressure of approximately 50 bar. Taking a factor of safety of two into account, the part is designed to withstand 100 bar. To assess the component's performance under deep-sea hydrostatic conditions, it underwent testing in the hyperbaric chamber test facility at NIOT. During the qualification process, the component successfully withstood the design pressure of 100 bar and imploded at 102 bar. This study is part of NIOT's ongoing efforts to indigenize deep-sea components using AM and assess its future prospects.
使用增材制造技术的浮标部件国产化
印度国家海洋技术研究所(NIOT)的海洋观测系统(OOS)小组参与了印度洋系泊数据浮标的设计、开发和维护。在北印度洋部署的系泊浮标系统提供实时、连续的海面气象和海洋参数观测,帮助监测极端天气事件和自然灾害,如气旋和海啸。浮标组件有不同的尺寸和形状,由各种材料制成,包括金属和塑料。然而,由于独特和关键的设计要求,深海部件的开发面临着制造限制造成的障碍。增材制造(AM)的出现满足了快速生产零件的需求。由于高压和低温条件,深海部件的设计和开发极其困难。因此,高冲击聚苯乙烯(HIPS)材料被选择用于水下浮子。浮子是在Fabheads 1K FDM打印机中使用基于颗粒挤出法的熔融沉积建模(FDM)增材制造技术制造的。这些水下浮子在水深500米的NIOT浮筒系统中使用,工作压力约为50 bar。考虑到二的安全系数,这部分设计承受100巴的压力。为了评估该组件在深海静水条件下的性能,它在NIOT的高压室测试设施中进行了测试。在鉴定过程中,构件成功承受了100 bar的设计压力,并在102 bar的压力下内爆。这项研究是NIOT正在进行的使用AM本土化深海部件并评估其未来前景的努力的一部分。
