Green Mega Ship Makes Call at Port of Tacoma
Port of Tacoma officials joined officials of Evergreen Group and its Hatsu Marine Limited subsidiary to mark the arrival of the new S-type, 7,024-TEU (20-foot equivalent container unit) green mega ship – the second is a series of 10 Evergreen Group S-type vessels – designed with a host of environmental features designed to protect the oceans and harbors the ships call on throughout the world.
According to Evergreen, features built into the Hatsu Sigma include:
* Double-skinned hull design;
* Fuel tanks located in areas to minimize the risk of oil pollution or fire as a result of grounding or collision;
* High-capacity oil-water separator that minimizes the oil content of waste water to be reduced to 15 parts per million;
* Large holding tanks enable vessels to avoid discharge in sensitive areas and maximize the amount of waste that can be held for disposal at specialized shore facilities;
* Enhanced holding tanks for "grey water" (waste and sewage);
* Main engines and generators incorporate low-NOx technology, enabling the vessel to operate on low-sulfur fuels;
* Advanced underwater hull coatings that have no detrimental affect on marine life; and
* The ability to shut down all shipboard generators while in port at terminals equipped with shore-based electricity.
With an overall length of 984 ft. (300 meters) and a beam of 140.5 ft. (42.8 meters), Evergreen's new S-type vessels can transport a capacity of 78,200 short tons at a service speed of 25.3 knots.
