Japan’s shipyards remain intact after quake

Japan’s major shipyards escaped the full impact of the March 11 earthquake and tsunami that struck the northeastern coast of the country with full force. An official at the Japan Ship Exporters’ Association said the devastating natural disaster “will have no impact on future export ship orders at all”. Although several small shipyards in the quake-hit areas were affected, major Japanese shipyards that build large vessels for exports are concentrated in western Japan and remain intact, the official said. Mitsui Engineering & Shipbuilding sustained “slight material damages” in the company’s Kasai Center and Chiba Works but did not consider such slight damages would cause serious impact on operations. “The rotational schedule of interruption of power supply due to the earthquake may affect our operation at our works and subsidiaries. However, the degree of the impact is not known now,” the company said in a statement. Japanese export ship orders rose for the 15th consecutive month in February o a year-on-year basis. Japanese shipbuilders received orders for 277 export vessels – 259 bulk carriers, 10 oil tankers and eight general cargo vessels – in the April-February period.

Tsnunami Debris Expected on U.S. Shores in 3 Years

The powerful tsunami triggered by the 9.0 Japanese earthquake destroyed coastal towns near Sendai, washing such things as houses and cars into the ocean. Projections of where this debris might head have been made at the international Pacific Research Center, university of Hawaii at Manoa. What their model predicts about the tsunami debris is that they first spread out eastward from the Japan Coast in the North Pacific Subtropical Gyre. In a year, the Papahanaumokuakea Marine National Monument will see pieces washing up on its shores; in two years, the remaining Hawaiian islands will see some effects; in three years, the plume will reach the US West Coast, dumping debris on Californian beaches and the beaches of British Columbia, Alaska, and Baja California. The debris will then drift into the famous floating junk yard, the North Pacific Garbage Patch, where it will wander around and break into smaller and smaller pieces. In five years, Hawaii shores can expect to see another barrage of debris that is stronger and longer-lasting than the first one. Much of the debris leaving the North Pacific Garbage Patch ends up on Hawaii’s reefs and beaches. These model projections will help to guide clean-up and tracking operations.

IMO Action Plan to address marine plastic litter from ships

  IMO?s Marine Environment Protection Committee (MEPC) in 2018 adopted the International Maritime Organisation (IMO) Action Plan to address marine plastic litter from ships, which aims to enhance existing regulations and introduce new supporting measures to reduce marine plastic litter from ships.

What is marine litter? 

  Plastic materials in all shapes and sizes are omnipresent in our seas and oceans. They break down extremely slowly in the marine environment, taking in excess of 400 years. Marine litter originates from many sources and causes a wide spectrum of environmental, economic, safety, health and cultural impacts. For example, marine litter can cause harm to sea life if ingested or even death if a marine mammal becomes entangled in litter.

  Marine litter has been defined by UN Environment (United Nations Environment) as “any persistent, manufactured or processed solid material discarded, disposed of or abandoned in the marine and coastal environment. Marine litter consists of items that have been made or used by people and deliberately discarded into the sea or rivers or on beaches; brought indirectly to the sea with rivers, sewage, storm water or winds; accidentally lost, including material lost at sea in bad weather (fishing gear, cargo); or deliberately left by people on beaches and shores.”

   Marine litter, including plastics and microplastics, is known to result from land-based sources in massive quantities but can also originate from ships. Debris particles have been observed in coastal areas, in waters far from anthropogenic pollution sources, in surface waters, in the water column of deep water and in ocean sediments, and from the equator to the poles, including trapped in sea ice.

  UN Environment estimates that 15% of marine litter floats on the sea's surface, 15% remains in the water column and 70% rests on the seabed.

  According to another study, 5.25 million plastic particles, weighing 268,940 tonnes in total, are currently floating in the world”s oceans.

What problems does marinelitter cause? 

  In addition to the environmental and health problems posed by marine litter, floating garbage and plastics pose a costly as well as dangerous problem for shipping, as they can be anavigational hazard and become entangled in propellers and rudders.

  Another problem requiring urgent remedial action is the massive accumulation of plastics, not only in coastal areas but also in the deep sea.

  This litter is harmful to marine life: sea creatures can become trapped inside containers or strangled by nets or ropes, and microplastics can also enter the food chain as they are indigestible when swallowed.
