2017 has been a standout year for additive manufacturing in marine and offshore operations. Desktop 3D printers can now be found in shipyard workshops and aboard rigs, where engineers use them to prototype and制作工具和spare parts. However, it is the rise of metal additive manufacturing that has started to cause a real stir.
In response to demand for metal 3D printing, global quality assurance and risk management company DNV GL has published its first classification guideline for additive manufacturing (AM) in the maritime and oil & gas industries. Covering all aspects of the process, the 48-page document is indicative of what officials believe could be a paradigm shift for vessel maintenance and repair.
“Everyone is paying attention”
海洋和海上的移动方式与汽车和航空航天几乎相同。数字化的经济利益是driving down traditional stock inventories并使用data-driven processes优化生产。“突然每个人都在关注。”says Marit Norheim，DNV GL Maritime的赫尔，材料和机械副总裁“对整个行业的利益相关者的影响是巨大的。”
零件Damen’s WAAMpeller，螺丝钉，轴承壳和船上的箱热交换器现在可以按需打印3D，为造船者提供了一个转折点。
诺海姆补充说：“如果可以根据当地甚至在船上的船上打印产品和组件，那么这确实是供应链的破坏性创新。”
Seizing the additive opportunity
What the new guideline ensures is that parts produce using additive manufacturing have a like-for-like quality compared to traditionally manufactured counterparts. In the document, which has been in production since 2014, DNV GL systematically covers all parts of the process, from design for additive manufacturing (DfAM) through to “specification of part-building requirements for end users.” The body breaks this down into 11 steps, each with its own action, basis, and involvement from DNV GL.
Norheim states, “With the introduction of the class guideline DNVGL-CG-0197, DNV GL is now ready to certify and support our customers and industry stakeholders to take advantage of this rapidly maturing technology.”
“这将使最终用户对产品的信心，并允许供应商提供其技术和产品，以用于船舶和海上装置。”
在这里停留
As proved bya number的其他战略伙伴关系this year, DNV GL firmly believes that additive is here to stay, Norheim says,
“这是一个应该接受的机会，而不是行业应该抗拒的挑战。”
DNV GL的主要材料专家Ramesh Babu Goindaraj补充说：“我们已经准备好证明并准备支持。”“这确实是一个新的维度，我们期待帮助我们的客户发现其潜力。”
