Oslo: DNV and the World Wide Fund for Nature (WWF) announced the joint development of the scientific concept ship to solve the thorny problem of increasing plastic waste in global seas. The plastic movement path and degradation process in the ocean are still largely unknown, so there is an urgent need to fill in the knowledge gaps related to the efficient cleaning of plastic waste.
It is estimated that plastic degradation in the ocean takes 10 to 500 years. By launching an action plan and developing a design concept for a professional scientific research vessel, DNV hopes to use practical methods to reduce plastic build-up and seek support worldwide for this action plan.
By 2020, the plastics in the ocean are expected to reach 230 million tons, most of which come from land and sea activities. Plastics are generally easy to accumulate in the relatively static waters of the five oceans.
Although plastic accumulation seems to be convenient for collection and cleaning work, the large accumulation of plastics and numerous unknown variables make clean-up work extremely challenging. For example, it takes about 80 years to clean up the surface of the five ocean currents by using 1,000 ships.
“Like carbon dioxide, the problem of marine plastic pollution is related to each of us,†said Bj?rn Haugland, chief technology and sustainability officer at DNV. “As with carbon dioxide, the effects of all current solutions are still unclear. Breaking through innovation is the general trend."
Therefore, DNV and WWF have jointly developed the conceptual design of a new scientific research vessel called Spindrift. The 85-meter-long scientific research vessel can support 38 researchers working at sea for 90 days, providing them with a flexible research platform to better understand the problem and test plastic collection solutions. The new scientific research vessel is equipped with a system for effective monitoring of the ocean from the air and water, designed to flexibly handle different collection techniques.
The new scientific research vessel will help solve the following problems: What is the depth of the underwater cleaning operation? How much plastic accumulation should be cleaned up? How can we minimize the chance of accidentally catching marine life?
“In addition, it would be important to improve the accuracy of estimating the amount of plastic waste if regulatory measures involving plastic producers and consumers are implemented in the future,†said Mr. Bi Haoran. “DNV encourages government agencies, industry partners and non-governmental organizations (NGOs). Take various measures to curb the continuous entry of plastics into the ocean, but this is not enough. What we need is to implement cross-border and trans-ocean pollution control measures on a global scale. Spindrift provides us with a cooperation and innovation. Great platform."
