Terrestial and Underwater Radiated Noise from Powerships: Testing and Evaluation

The increase in shipping activity globally has resulted in an increased awareness of impacts on the marine environment. Effects of noise pollution, especially on marine life, have become highly prominent. Marine life is extremely sensitive to noise pollution. Due to their extreme reliance on underwater sounds for basic life functions like searching for food and mate and an absence of any mechanism to safeguard them against it, underwater noise pollution disrupts marine life (Singla, 2020). In short, marine animals depend on sound to live, making and listening to it in various ways to perform various life functions (US Bureau of Ocean Energy Management, 2014).

Noise travels much more in water, covering greater distances than it would do on land while travelling through air. Underwater sound has both pressure and particle motion components and hearing can be defined as the relative contribution of each of these sound components to auditory detection (Popper AN, 2011). Sounds radiated from ships are among the underwater noise sources. Among shipborne Underwater Radiated Noise (URN) sources are the following:

  • Propeller’s rotational turn and the blades hitting to water flow lines
  • Propeller’s cavitation
  • Ship hull structure’s interaction water (fluid-structure interaction)
  • Mechanical noises from onboard machinery

All of these noise sources are radiated to underwater from ships, especially when the ship speed is at higher rates, i.e. above 15 knots.

When a Powership is considered, out of the 4 aforementioned noises, only mechanical noise sources are of concern as there are no noises that emanate from the other three sources because the Powership is docked. Mechanical onboard noises are still of concern and therefore need to be evaluated and tested for the assessment of their potential negative effects to marine life.

GDS Engineering R&D has the capability for measuring the underwater radiated noise and assessment of the results based on the effect to the sealife in the region.

    Electro-Magnetic Compatibility (EMC) of Marine Devices and Electrical Equipment

    Devices used onboard a ship are exposed to harsh electromagnetic environments, whether in the propulsion, deck or bridge area of a ship. Testing of such devices for Electro-Magnetic Compatibility (EMC) is therefore very important. Otherwise, manufacturers can face difficulties during the certification and procurement stages.

    EMC testing and certification  services to ensure your marine products comply with relevant international standards and regulations is a MUST!

    GDS Engineering R&D does not perform these tests yet; however, have the information on design and test knowledge. The requirements include the international conventions as agreed by the International Maritime Organization (IMO) for Safety of Life at Sea (SOLAS).

    Currently, we have observed that these tests are conducted by reputable agencies like ELEMENT.

    The testing laboratories use the following standards to test the marine electronic, digital or electrical devices for certification to IMO SOLAS requirements, guidance, or recommendations:

    • IEC 60945
    • IEC 60533
    • Lloyds Register Test Spec No 1
    • DNV Certification Notes 2.4
    • IEC 60092

    Support and guidance from the initial design stage

    The use of composite materials in ship construction together with new radio technologies and high power electronics are changing the requirements and design goals that need to be achieved to ensure electromagnetic compatibility.  Element is well placed with our knowledge of both standards and the target environment to provide detailed guidance of the best compliance strategies to adopt for your marine products.

    CE Marking and Wheel Mark certification

    Element performs EMC testing in conjunction with climatic and environmental test requirements to meet dedicated marine standards and be compliant with CE marking legislation. We make sure your marine equipment complies with the relevant EMC standards listed in the Marine Equipment Directive to help you achieve the Wheel Mark certification.

    Yeni ürünler nasıl sertifikalandırılıyor?

    Türkiye’nin ilk yerli can kurtarma ekipmanlarını üreten Vira Denizcilik yetkilileri ürünlerinin sertifikalandırma süreçlerini anlattılar.

    İTÜ Denizcilik Fakültesi Gemi Makineleri İşletme Mühendisliği 4. sınıf öğrencileri Ali Mazlum Yıldız, Mert Kara, Fatih Mehmet Alkaç’ın haberi

    Dünya ticaretinin büyük bir bölümü deniz üzerinden gemiler ile yapılmaktadır. Bu gemiler IMO çatısı altında belirli standartlarla donatılarak üretimi yapılmaktadır. Dünya denizcilik pazarında önemli bir yer edinen ve bu yeri her geçen yıl büyüterek devam eden ülkemiz yerli üreticileri hem sertifikasyon sürecinde hem de ürünün ilk yerli üretiminin getirdiği çeşitli zorluklar ile karşılaşmaktadırlar. Bu sertifikasyon sürecinde yerli üreticilerimizin yabancı üreticilere göre daha fazla zorluklar ile karşılaştığını söylemek mümkündür. Bu zorlukların üstesinden gelebilmek için konuyu detaylı bir şekilde incelemek önem arz ediyor.

    Bu önemli konuda İTÜ Denizcilik Fakültesi Gemi Makineleri İşletme Mühendisliği öğrencileri olarak İsmail Çiçek hocamızın danışmanlığında yürütülen bir tez çalışması yaparak İTÜ Denizcilik Test Uygulama ve Araştırma Merkezi (İTÜ DETAM) çalışmaları kapsamında yürütülen ürün sertifikalandırma projelerini inceledik ve bu ürün çalışmalarının testleri konusundaki başarı öykülerinden birisini aktarmak istedik. Bu anlatımımızın ülkemizdeki başka firmalarımıza da örnek ve motivasyon sağlamasını umuyoruz.

    İTÜ Denizcilik Fakültesi öğrencileri olarak tezimizin içeriğini de kapsayan bu konuda ülkemizde ilk yerli can kurtarma ekipmanları üretmeye başlayan ve yıllardır ürün yelpazesini arttırarak dünya denizcilik pazarında yer edinen Vira Denizcilik Genel Müdürü Selahattin Yılmaz ile yaptığımız röportajda şu konulara değindik.

    – Vira Denizcilik olarak yerli üretime geçiş kararını nasıl aldınız?

    Firmamız 1996’dan önce safety ekipmanlarını ithal ederek ülkemiz firmalarına ve yabancı firmalara bu ürünlerin satışını yapmaktaydı. Biliniyor ki safety ekipman denizcilik pazarının büyük bir bölümünü oluşturuyor. Firmamızın kurucusu olan Kapt. Selçuk Karakaş bu konudaki deneyimi ve bilgi birikimini kullanarak ülkemizde can kurtarma ekipmanlarının üretiminin yapılabileceğini düşündü. İki yıllık çalışma sürecinin ardından üretime başlanmıştır.
