Noise control on commercial ships
This year, three LPG Carrier and one Chemical Tanker were the first four Japanese ships to fulfil the new IMO Code on Noise MSC.337(91). The new mandatory limits required new approaches on the shipdesign at all four yards. With the assistance of DW-ShipConsult, the initial designs were analysed concerning their acoustic properties. Noise predictions for onboard noise were conducted, critical areas were identified and recommendations for noise countermeasures were given. In the process DW-ShipConsult was able to identify the most economic approach to comply with the MSC.337(91) thus helping the shipyards to save costs. Kegoya-Dock, Kyokuyo Shipyard, Miura and Kitanihon Shipbuilding showed during their sea trials that the measured sound levels on their ships all remain below the required limits. This successful implementation of a good noise control concept provided a big relief for the shipbuilders who needed to get it right on the first try.
SMM Hamburg 2016
For the second time DW-ShipConsult exhibited their noise and vibration control services at the SMM from 06.09-09.09.2016 in Hamburg. In cooperation with Wölfel GmbH showed the newest developments in noise and vibration control on ships. We were happy to welcome so many interested parties from all over the world and having so many conversations on shipacoustic issues. We would like to thank everybody who stopped by at our booth.
New Silencer for ships
DW-ShipConsult developed a new type of silencer for ships. In cities like Hamburg, where the port is in close vicinity to residential areas, the noise emitted by ships during harbour operation becomes an ever growing point of concern. Especially low-frequency noise from the generator engine exhaust can travel long distances and is perceived as a very annoying tone by the human ear. The usually applied absorber-type silencers on the ships do not provide sufficient attenuation at these low frequencies. To counter this problem, DW-ShipConsult developed a special low frequency silencer, able to attenuate the most annoying tones. A key element of this invention is possibility of a quick integration during the routine port calls. This way, installation costs are kept to a minimum and idle time is avoided. Noise in ports is no imperative any more. It is a challenge, easy to solve.
Noise and Vibration Control at the Sea Japan Fair
From 13th to 15th April we will present our services in noise and vibration control at the Sea Japan Fair in Tokyo. We are looking forward to establish new cooperations with local shipbuilders and also to meet our trusted Japanese customers. We cordially invite all interested companies to our booth GER-03 to learn more about our noise and vibration control philosophy, which provides our customers with a plan for the most efficient ship noise mitigation measures in the early design stage.
DW-ShipConsult, exhibitor at the Marintec China
From 1st to 4th December 2015 the Marintec China trade fair took place in Shanghai where DW-ShipConsult had a booth in the German Pavillion. Noise control on board is becoming more important in the shipbuilding industry as shown by the numerous visitors and requests. Many customers are looking for an independent and professional recommendation for noise control measures now that the new IMO Code on Noise MSC.337(91) is applied for an increasing number of new building projects. During the Sea Japan fair we are going to show how a conceptual noise analysis and noise control during the early phases of a ship design is the best way to receive these recommendations.
Trip to Japan
DW-ShipConsult has taken a 3 weeks business trip to Japan to visit our customers and meet new contacts. During the tour organized by CAJS and ClassNK we visited 13 different shipyards inspecting the current state of noise and vibration control and giving advice where needed. Furthermore DW-ShipConsult presented our abilities to support shipyards in an efficient implementation of the new IMO Code on Noise [MSC.337(91)] in 4 ClassNK seminars. More than 400 participants from the Japanese maritime industry were able to learn about the advantages of an early noise analysis. ClassNK, CAJS and DW-ShipConsult are in favor of continuing the successful collaboration.
Testing pfh-Prototype "Plattenyacht"
Just in time for the Kieler Woche the pfh-prototype "Plattenyacht" has arrived in Kiel. DW-ShipConsult staff were able to experience the advantages of the pfh during a test drive. For further information on Plattenyacht and pfh go to www.pfh-ships.com
