The Port of Oakland\u2019s largest marine terminal Oakland International Container Terminal\u00a0(OICT) has cut diesel emissions from\u00a013\u00a0of its\u00a0massive yard cranes by 95 percent after retrofitting them with hybrid-electric\u00a0engines.\u00a0<\/p>\n
Terminal operator Stevedoring Services of America (SSA)\u00a0said that the project will eliminate about 1,200 metric tons of greenhouse gas emissions annually from each crane. <\/p>\n
\u201cRetrofitting our rubber-tire\u00a0gantry\u00a0cranes to battery power produced remarkable results,\u201d s<\/em>aid Crane Manager Ken Larson<\/strong>, at SSA Marine\u2019s OICT. <\/p>\n \u201cWe\u2019re impressed with the huge drop in emissions from equipment that we regularly use on the marine terminal.\u201d<\/em><\/p>\n SSA said that the clean air project would result in a 93 percent reduction in diesel fuel.\u00a0The older\u00a0engines\u00a0used 10 to 13 gallons of diesel fuel an hour\u00a0whereas\u00a0the\u00a0hybrids\u00a0use about three-quarters of a gallon an hour, according to Larson.<\/p>\n In the first project of its type at the terminal, SSA replaced 1,000-horsepower diesel generators on its yard cranes with 142-horsepower diesel hybrids. <\/p>\n The new power plants have\u00a0small\u00a0diesel engines used only to charge a crane\u2019s pack of batteries. Each crane has a housing unit that contains the hybrid generator.<\/p>\n \u00a0Larson said that the project was challenging, including the construction of new electrical\u00a0systems\u00a0for input power protection when converting current from AC to DC on a crane. <\/p>\n As explained, the hybrid generators capture energy as a container is lowered, and have a better performance than the older diesel generators because there is no delay in power delivery to the crane.<\/p>\n Combined, the thirteen 90-foot-tall cranes can lift as many as 1,000 containers a day on and off trucks at OICT.<\/p>\n The project to\u00a0replace 13 diesel-powered\u00a0rubber-tire\u00a0gantry crane\u00a0engines\u00a0with\u00a0Tier 4 Final hybrid\u00a0engine was supported by the Air District\u00a0$5\u00a0million\u00a0in\u00a0grant\u00a0funding as part of the Air District\u2019s Community Health Protection Program (CHP\u00a0\u2013 AB134).<\/p>\n The first crane was retrofitted in February of 2019 and the 13th crane was converted\u00a0in July 2020.<\/p>\n The project was part of the Port’s Seaport Air Quality 2020 and Beyond Plan. <\/p>\n The post Port of Oakland’s marine terminal slashes emissions with electric cranes<\/a> appeared first on Offshore Energy<\/a>.<\/p>\n world maritime news<\/p>\n","protected":false},"excerpt":{"rendered":" The Port of Oakland\u2019s largest marine terminal Oakland International Container Terminal\u00a0(OICT) has cut diesel emissions from\u00a013\u00a0of its\u00a0massive yard cranes by 95 percent after retrofitting them with hybrid-electric\u00a0engines.\u00a0 Terminal operator Stevedoring Services of America (SSA)\u00a0said that the project will eliminate about 1,200 metric tons of greenhouse gas emissions annually from each crane. \u201cRetrofitting our rubber-tire\u00a0gantry\u00a0cranes to …<\/p>\n","protected":false},"author":1,"featured_media":16237,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[64],"tags":[2074,225,1582,531,10485,953,4520,1256],"class_list":["post-16236","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-maritime-news","tag-cranes","tag-electric","tag-emissions","tag-marine","tag-oaklands","tag-port","tag-slashes","tag-terminal"],"_links":{"self":[{"href":"https:\/\/www.al-sindbad.net\/rest\/wp\/v2\/posts\/16236","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.al-sindbad.net\/rest\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.al-sindbad.net\/rest\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.al-sindbad.net\/rest\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.al-sindbad.net\/rest\/wp\/v2\/comments?post=16236"}],"version-history":[{"count":0,"href":"https:\/\/www.al-sindbad.net\/rest\/wp\/v2\/posts\/16236\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.al-sindbad.net\/rest\/wp\/v2\/media\/16237"}],"wp:attachment":[{"href":"https:\/\/www.al-sindbad.net\/rest\/wp\/v2\/media?parent=16236"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.al-sindbad.net\/rest\/wp\/v2\/categories?post=16236"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.al-sindbad.net\/rest\/wp\/v2\/tags?post=16236"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
