一个制造联盟，包括ABS,Sembcorp Marine和3D Metalforgehave fitted enhanced 3D printed parts to aconocophillips极地油轮。
Using 3D printing, the companies created a functional centrifugal pump shaft, a combined brine/air injector nozzle, and an effluent pump coupling device for the ‘Polar Endeavour.’ Each of the ship’s new parts has not only passed industry safety checks, but they’ve also reportedly outperformed many mass-manufactured alternatives.
Sembcorp研发主管Simon Kuik说：“与ABS和3D Metalforge的合作是Sembcorp Marine的延续，以创新和提高我们的生产能力和能力。”“这一发展使Sembcorp Marine能够进一步完善我们的产品，并安全，更有效地提供定制的解决方案。”
胜科的海上任务
Between them, ABS and Sembcorp have built up substantial experience in 3D printing seaworthy parts over the last few years. In particular, ABS is heavily involved in the regulatory side of maritime AM, and it recently released parameter sets for fabricating offshore objects, placing a specific emphasis on process repeatability.
Sembcorp, meanwhile, is somewhat of an offshore production specialist, and it has deployed 3D printing within its MRO operations for over four years. The company has close ties with Singapore’s国家添加剂制造创新集群, and the firms have worked together to develop整个船设计的数字双胞胎.
在其他地方，Sembcorp已承诺利用3D打印来为新船只创建大型结构并进行全船上的维修。最近，该公司还为新的添加剂零件开发了参数集，并在海事领域寻找了该技术的新应用。
2019年，SEMBCORP从DNV GL获得了认证to use 3D printing as a means of repairing non-critical parts, such as the worn-out metal sleeves often used in pumps. Now, as part of its latest nautical project, the company has partnered with ABS and 3D Metalforge to create components that aren’t just novel but represent a functional improvement on the parts they’re replacing.
Decking out the Polar Endeavour
Operated by ConocoPhillips, the Polar Endeavour is a 20-year-old crude oil tanker, and given that it’s constantly tasked with carrying heavy loads along U.S. shores, its functional parts need to be foolproof. At present, the ship’s spares and repairs are produced via traditional casting or forging techniques, but now the ABS-led group has deployed 3D printing to give them an upgrade.
在项目期间，财团制造了三个非常不同的组件，并对它们进行了严格的行业标准测试。通过鲜艳的颜色通过了海洋试验后，增强的零件现在已安装在极地努力上，准备承担海洋所面临的任何挑战。
尽管ABS的全球工程和技术高级副总裁帕特里克·瑞安（Patrick Ryan）表示，该公司“自豪地支持该项目”，但他强调了安全在未来的研发中的重要性。瑞安说：“这是一项技术的关键发展，在该行业的未来中肯定具有重要作用。”“ ABS致力于确保引入这些类型的零件，而不会损害安全性。”
In addition to outperforming conventional maritime components, the 3D printed versions also proved the technology’s potential for reducing lead times. Given that other maritime bodies such as the Dutch Navy are increasingly3D打印备件按需，该项目也可以作为改善零件在商业船上的零件可用性的先驱。
海上增材制造
3D打印已经在海军工程领域建立了蒸汽头，许多造船厂正在试用该技术以生产最终用途的零件。
西班牙造船厂Navantia甚至与卡迪兹大学（UCA）开发一个专用海事3D打印机. Using the custom system, which they nicknamed ‘S-Discovery,’ the engineers were able to fabricate two grills for the ventilation system of the Monte Udala Suezmax oil tanker.
Additive manufacturing has also found extensive naval military applications recently. In January 2021, for instance, defense contractor海军集团3D打印了整个螺旋桨for the French Navy. Featuring a 2.5-meter span and five 200kg blades, the large-format part is reportedly the biggest of its kind in the world.
同样，美国海军海军海系统司令部（NAVSEA）已开始批准用于船上安装的3D打印零件。第一个批准的组件，一个prototype drain strainer orifice（DSO）组装旨在使航空母舰上的蒸汽管线引流。
