Shipowner ConocoPhillips Polar Tankers worked with ABS, Sembcorp and 3D Metalforge to install working 3D printed mechanical parts on the tanker Polar Endeavor equipped with the American flag.
Usually, the parts used in shipbuilding and repair are manufactured by casting or forging technology. For this project, the consortium used additive manufacturing (AM, also known as 3D printing) to manufacture three types of parts-gear sets and centrifugal pump shafts; nozzles for salt water/air jets; and full flexibility for sewage pumps Coupling. According to ABS, the rigorous testing process shows that 3D printed alternative products are of higher quality than traditionally manufactured products.
AM technology uses a print head on a small mechanical gantry to produce parts according to a digital CAD template, thereby constructing materials layer by layer. With the development of various systems and technologies on the market, the range of available metal printing materials is very wide, including stainless steel, maraging steel, bronze, Inconel and (for aerospace users) titanium. The small footprint of the 3D printer means that products and components can be manufactured locally (even on board), thus shortening delivery time. The additive method is particularly suitable for the manufacture of short production cycles and complex parts.
“ABS is proud to be able to support this practical project… This is a key development in technology that will undoubtedly play an important role in the future of the industry.” said Patrick Ryan, senior vice president of global engineering and technology ABS.
Other well-known 3D printing companies include a joint venture between Wilhelmsen’s aquatic products division and Thyssenkrupp (formerly ThyssenKrupp), which produces through AM Parts provide services to commercial marine customers. Clients include Berge Bulk, Carnival Maritime, Thome Ship Management, OSM Maritime Group, Administrative Ship Management and Wilhelmsen Ship Management.
Abhinav Singhal, director of ThyssenKrupp Innovations, said in a statement last year: “Our marine customers have responded very positively to the adoption of additive manufacturing.” “They are realizing the shortened delivery time. Cost reduction and spare parts supply chain have the advantage of greater flexibility. For the maritime industry, this will be a real game changer, and we are proud to be able to provide it with Williamson.”
The United States Naval Marine Systems Command (NAVSEA), Norfolk Naval Shipyard and Newport News Shipyard in Huntington Ingles have also taken steps to introduce 3D printed metal parts in the naval supply chain. Critical or obsolete parts of the target. As of October 2020, NAVSEA has approved a total of 182 3-D printable parts in its database, and more than 600 are undergoing engineering review.
Last week’s hearings about the tragic sinking of the ill-fated fishing boat Scandies Rose raised questions about the requirements of the stability manual for crab boats, which are usually subjected to severe freezing spray in Alaskan waters. For decades, the sinking of many crab ships has been attributed to icing and loss of stability, but the U.S. Coast Guard’s ice accumulation design standards relied on the rules of the International Maritime Organization (IMO), which did not take into account the problem of crab ships. -leads to…
Coast Guard Chet Kimball has successfully conducted a two-week patrol to combat illegal, unreported and unregulated fishing (IUU fishing), which has further promoted the United States’ security and partnership in the Indo-Pacific region. Relationship commitment. As part of “Operation Blue Pacific,” the crew of the Campbell was deployed to support national security goals. Kimball’s crew is prepared to take targeted and intelligence-driven enforcement actions and respond to predatory or irresponsible maritime behavior. Patrol about 3,600 miles near
The Royal Navy patrol ship “Mersey” recently tracked the movement of the surfaced Russian attack submarine as it passed over Britain. The task of the maritime patrol ship is to accompany the Kilo-class diesel attack submarine RFS Rostov Na Donu (Rostov Na Donu), which emerges from the North Sea and the English Channel and sails south from the Baltic Sea to the Mediterranean. Rostov Na Donu is part of the Russian Black Sea Fleet, and Mersey’s crew tracked and reported…
[Written by Trevor Phillips-Levine, Dylan Phillips-Levine, and Walker D. Mills] In August 2020, USNI News reported that the Navy “has embarked on the development of the first new carrier-based fighter in nearly 20 years.” Although the F-35C Lightning II will still be in production for many years, the Navy needs to prepare another fighter to replace most of the F/A-18E/F/G Super Hornets and Growlers by the mid-2030s. This new program will design the aircraft. Although this is an important development, it…
