Norweigan subsea robotics specialist孔斯伯格·费罗蒂奇（Kongsberg Ferrotech）已经显示，目前正在开发一种水下3D打印技术，用于维修海床水平管道。
Designed to complement the capabilities of its existing aquatic robotics systems, the company’s upcoming metal additive manufacturing add-on is set to be used as a means of carrying out remote maintenance on damaged marine infrastructure, as well as rebuilding it where necessary.
“先进的海底机器人为客户的成本和时间带来了重大节省 - 以环境友好的方式进行，而无需送出海洋。”“在过去的五年中，我们的解决方案一直在开发，我们将开始在2021年第三季度为东南亚市场提供水下复合维修。”
“With our Inspection, Maintenance and Repair (IMR)-robotic technology, we bring the workshop to the damage – not the damage to the workshop.”
金斯伯格·费罗托奇（Kongsberg Ferrotech）的AM野心
金斯伯格·费罗托奇（Kongsberg Ferrotech）的金属3D打印项目已经与等,Sintef,Gasscoand theResearch Council of Norwayto develop the technology for underwater Maintenance, Repair and Overhaul (MRO) applications.
通过该计划，Kongsberg Ferrotech旨在为其现有的海底流量管道控制和修复（SFCR）机器人提供升级，这使他们能够对航海流程线进行原位维修。目前，该公司的“ Nauticus”机器人能够将其放到海中，建立真空并修复任何破碎的管道，然后再返回地面而不会留下任何碎屑。
然而，借助其新的“终生扩展”技术，该公司表示，升级的Nautilus可以“大大延长多个海上资产的寿命”。实际上，尽管该公司最初通过其3D打印过程将损坏的流线修复定位，但它还为开发其设备开发其他功能而敞开了大门，这在新领域创造了机会。
“The rapid development of 3D printing technology is creating new opportunities and markets going forward,” explained Brede Lærum, Head of 3D printing at Equinor. “Combining this technology with Kongsberg Ferrotech’s robots opens many exciting new possibilities for subsea repairs and modifications. We are looking forward to a close collaboration with our industry partners.”
孔斯伯格·费罗蒂奇（Kongsberg Ferrotech）’s technology may have been under development since 2016, but it has now reportedly passed deepwater composite repair testing at the Trondheim Fjord in Norway, and the firm says that it’s expected to be commissioned for its first commercial application “as early as 2022.”
卡尔森总结说：“与Equinor，Gassco和Sintef的合作代表了水下装置，水下运输系统和金属维修研究中的世界一流的专业知识。”“为终生扩展开发水下3D打印的独特机会是重要的技术飞跃 - 不仅对于孔斯伯格·费罗托奇（Kongsberg Ferrotech），而且对于该行业而言。”
3D打印的管道重复潜力
在管道维修中采用3D打印可能对航海公司非常有益，为它们提供了成本和时间节省，并有可能完全消除停机时间的需求。过去，中国公司Nanfang添加剂制造技术还与当地合作伙伴进行了重大研究，以EBM 3D打印油和气体生产线零件进行。
与金斯伯格·费罗托奇（Kongsberg Ferrotech）的研发计划不同，南芬（Nanfang）的项目发生在海平面以上，但确实产生了400千克prototype pressure vessel cylinder。同样，2019年，金属3D打印机制造商滴虫选择许可两项CSIRO专利与潜在的油，天然气和采矿应用有关的钛管，阀门和连续管道的添加剂制造。
Elsewhere, on a much smaller scale, scientists atTianjin University有3D打印了可自定义的机器人that’s capable of climbing and monitoring pipes at industrial facilities. Featuring soft bending mechanisms and modular grippers, the remote-controlled bot has been designed to prevent future factory production delays.
