Putting a window and lasers in a ship’s hull

Melbourne and Indonesian scientists work to improve shipping efficiency

Every shipping manager wages an endless battle against fouling – the bacteria, seaweed, barnacles and other marine life that take residence on the hull of ships. This biofouling is thought to add more than 20 per cent to the fuel costs of commercial shipping. That’s a big cost for the maritime trading nations of Australia and Indonesia.

Using lasers and a window in a ship’s hull, researchers will assess how quickly the efficiency of the ship declines, and then how to balance fuel efficiency and the cost of putting a ship in dry dock to clean it.

Memasang jendela dan laser di lambung kapal

Para ilmuwan Surabaya dan Australia bekerja sama untuk meningkatkan efisiensi perkapalan

Para ilmuwan bersedia diwawancarai dalam Bahasa Indonesia dan Bahasa Inggris. Liputan video dan foto kapal feri dapat dilihat di http://australiaindonesiacentre.org/media

Setiap manajer perkapalan terus-menerus berjuang memerangi fouling (proses menempelnya biota pada permukaan kapal) – yaitu bakteri, rumput laut, teritip, dan mahkluk laut lain yang mendiami lambung kapal. Biofouling ini dianggap dapat menaikkan biaya bahan bakar kapal komersial lebih dari 20 persen. Ini merupakan biaya yang besar bagi aktivitas perniagaan maritim antara Australia dan Indonesia.
Dengan menggunakan laser dan jendela di lambung kapal, para peneliti dapat menilai seberapa cepat efisiensi kapal berkurang, dan bagaimana cara menyeimbangkan antara efisiensi bahan bakar dan biaya parkir di dok apung (dry dock) untuk membersihkan kapal.
