This year, despite innumerable challenges and setbacks, a great number of new U.S.-flagged vessels made their way into service. In addition to Maid of the Mist's new electric tour boats James V. Glynn and Nikola Tesla featured Wednesday, the newbuilds highlighted below are some of the most noteworthy to come out of U.S. shipyards in 2020.DredgerU.S. dredging contractors have been adding tonnage in a big way. This Spring, Callan Marine added a significant piece to the U.S. fleet with its new Jones Act cutterhead suction dredge (CSD) General MacArthur.

Dredging technology company VOSTA LMG will be moving its headquarters from Amsterdam to Delft in a few days. The move will bring the company closer to its customers, while ensuring continuity of operations and the excellence its customers have come to expect in terms of its product and service offerings. The new address, Olof Palmestraat 10 in Delft, houses a number of technology providers. “We’re pleased with this move to these modern, well-serviced premises”, says Managing Director Mr. Yuen. “It brings us closer to where the action is in terms of state-of-the-art technology—but also closer to our customers. In a word, it’s another step forward for the company. And our customers can expect us to continue providing the best in products and services.”

Idreco (International Dredger Constructions) of the Netherlands informs it has designed, built and installed its second dredger, an ISD 600 with a digging depth of 30 meters, at the Inga Dam in The Democratic Republic of Congo. The dredge has a mixture production and solids production of approximately of 5,000m3/hr and 1,500m3/hr using an Idreco designed IDP 600 pump. The Inga Dam, operated by Société Nationale d'Électricité (SNEL), is the largest hydro-dam in Africa and generates approximately 1,775 megawatts of electricity.

Celebrating a company milestone this week, VOSTA LMG notes it has been 50 years since the company started with the development and production of bayonet dredge ball joints. The 50 years are a unique amount of experience for the dredge component and it overlaps a significant part of the total history of VOSTA LMG, which goes back to 1873 when the Lübecker Maschinenbau Gesellschaft (LMG) was founded in the German town of Lübeck. The first steps in bayonet dredge ball joints were taken in 1965 in the Dutch village of Spaarndam at Stapel Shipyard…

VOSTA LMG has been awarded an order for efficient dredge ball joints from maritime services company Royal Boskalis Westminster. The order consists of a series of high pressure Crossover ball joints suitable for dredge pipes with an internal diameter of 1000 mm. The Crossover ball joint is a new and patented design ball joint which utilizes two wear liners to provide optimal flow performance and maximum wear protection. “We are very happy to announce this prestigious order, following recent deliveries of Crossover ball joints in the Middle East…

The Crossover ball joint is a new dredge ball joint that provides optimal flow performance, its manufacturer VOSTA LMG said. Through computational fluid dynamics (CFD) the frictional losses and turbulence have been reduced. Conventional dredge ball joints act like a ball valve when tilted, causing the flow area to reduce and frictional losses to increase. The patented Crossover design incorporates two wear liners which are shaped to provide full flow area in any tilted position.

For enhancing the draft in ports or undertaking major dredging projects, India still relies on foreign dredging giants, a situation not likely to change unless the government comes out with a policy encouraging investment in the dredging industry. European dredging giants continue to make a clean sweep of all major Indian dredging projects, a market condition largely attributed to the lack of an environment conducive to encouraging Indian companies into large scale dredging. In short, there are no parallel “protectionist policies” in place like those that exists in several maritime countries. Big players in the India dredging market…

Al Jarraf, meaning “dredging vessel” in Arabic, was launched on Wednesday October 27 at the ASL Shipyard in Singapore. VOSTA LMG is responsible for the design, supplied the components and developed the dredging technology together with MEDCO and DEME. VOSTA LMG built the main dredging components in Asia, 100% to European standards. Owner of the vessel is Middle East Dredging Company (MEDCO), a partnership between DEME, United Development Company (UDC), and the Qatari government. Two basic characteristics of the new CSD Al Jarraf qualify specifically for assignments in the Gulf region.

The Port Authority Board of Commissioners has authorized a study harbor dredging in the Port of New York and New Jersey to identify, develop and explore innovative and cost-effective ways to remove and dispose of sediment from the port's channels and berths. The goal of the $4 million study is to find the most environmentally sensitive and the most effective way to deepen the port's channels to 45-ft. and then to 50-ft. The deeper channels are needed to accommodate a new generation of cargo megaships that can handle over 6,000 truck-size containers and require deep water to operate. The study will be done in two phases. The first, which will take approximately two years…

In January 2003 VOSTA LMG received an order from Hudong Zhonghua Shipyard for the design and supply of all dredging components for a Trailing Suction Hopper Dredge (TSHD) for the Chinese Harbor Authority Huanghua Port. The dredge was handed over in a festive ceremony by Hudong Zhonghua Shipyard to Huanghua Port Authority on 11 November 2004, after successful dredge trials in the Yangtze estuary. "Shen Hua" has now started her duty; the required, continuos dredging work to maintain the required depth of the port waterway entrance of Huanghua Port.

Ellicott International offers details on a new type of dredge which actually walks by itself. The dredge moves on three moving spuds or traveling carriages enabling it to remain in exact position at all times because there are always two spuds firmly anchored in the bottom. It walks with the spuds while floating on the surface. This positioning allows the cutter to move forward into the next cut without losing position. This same technology also enables the dredge to move backwards to pick up contaminated material which dredging may have missed yet still remains in the same exact position to continue the forward dredging. The new dredge lends itself to precise dredging and positioning especially in rivers where there are currents.
