Wärtsilä Marine Solutions used additive manufacturing (AM) in order to create a crucial component for an inert gas system; In this technological step, DNV GL assisted in a time when initial production prototypes displayed an unexpected characteristic.
DNV GL and Nanyang Technological University, Singapore, are supporting academic advances in additive manufacturing, the process of 3D printing – for the maritime, oil and gas and other industries, through a four-year research collaboration agreement. The research collaboration will focus on developing industry standards, quality assurance processes, certification and supply chain tracking for the additive manufacturing sector.
Huisman informed that it delivered the first ever class certified, 3D-printed crane hooks. The 3D-printed hooks were certified following load testing at more than double their safe working load. The hooks are certified for offshore use based on ABS standards. The OOS Serooskerke will be the first ship to have a 3D-printed crane hook installed.
Partners are to use 3D techniques to present the first ultra-high-resolution images of Titanic wreckage for scientists and the general public. A group of organizations will apply advanced underwater imaging technology to monitor and document the wreck that was discovered in 1985.
3D at Depth, a subsea imaging company, made use of new laser technology to create a 3D reverse engineered model of the wreck of an historical U.S. Navy plane. The underwater survey technique integrates photogrammetry with Subsea laser LiDAR (SL) technology to create accurate, precise, reverse engineered 3D models.
A joint industry program between Maritime Port Authority of Singapore (MPA) and DNV GL class society was announced on April 9. The joint program will consist of ten member companies of the Singapore Shipping Association (SSA) to examine how spare parts produced by 3D printers can help the industry to cut costs and downtimes.
The MPA Singapore signed two MoUs for Additive Manufacturing, also known as 3D printing. An MoU with PSA, the National Additive Manufacturing Innovation Cluster and 3D MetalForge will establish the world’s first on-site AM production facility for port applications; and. MPA will aklso collaborate with NAMIC and the Singapore Shipping Association on an AM Joint Industry Programme for marine parts.
On 11 October, the US Naval Sea Systems Command announced approval of the first metal part created by additive manufacturing for shipboard installation. A prototype drain strainer orifice (DSO) assembly will be installed on USS Harry S. Truman in 2019 for a one-year test and evaluation trial.
DNV GL sees great growth on the adoption of Additive Manufacturing in maritime and ONG industries, noted Dr. Ing. Sastry Yagnanna Kandukuri, Global Additive Manufacturing Lead at DNV GL, adding however that it will likely take 3 to 5 years before the full-scale application of 3D printing.
As the issue of additive manufacturing or 3D printing is gaining ground in the marine industry, Braemar Managing Director – Asia, considers how 3D printing could be used both onshore and aboard to reduce delays relating to machinery breakdown.
