In line with these findings, Berg Propulsion designed blades tailored for the operation, improving efficiency significantly, according to Sakandelidze.<\/p>\n<p> \u201cEfficiency gains are made for much of the time and, at 12 knots, the new blades achieve up to 50% higher efficiency than the ones they replace,\u201d he said.<\/p>\n<p> With performance improved at the speeds most commonly required during operations, <em>Indian Express<\/em> is expected to achieve an astonishing 22% fuel saving overall, as well as lower emissions. The reductions should exceed the requirements of the IMO\u2019s Carbon Intensity Initiative (CII) goals for 2026.<\/p>\n<p>Berg\u2019s focus targets hydrodynamic upgrades such as blade optimization, control system upgrades such as installing an engine pitch and rpm optimization system. It also extends to Dynamic Drives, and electrical upgrades to run shaft alternators with variable frequency coupled with energy storage, said Jonas Nyberg, Managing Director West for Berg Propulsion.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>A recent retrofit to optimize a container ship\u2019s propeller blade design has brought performance and fuel efficiency gains.<\/p>\n","protected":false},"author":8,"featured_media":939,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[40],"tags":[],"sponsor":[],"class_list":["post-938","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-repair-conversion"],"acf":[],"_links":{"self":[{"href":"https:\/\/www.motorship.com\/propulsion-and-future-fuels-conference\/wp-json\/wp\/v2\/posts\/938","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.motorship.com\/propulsion-and-future-fuels-conference\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.motorship.com\/propulsion-and-future-fuels-conference\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.motorship.com\/propulsion-and-future-fuels-conference\/wp-json\/wp\/v2\/users\/8"}],"replies":[{"embeddable":true,"href":"https:\/\/www.motorship.com\/propulsion-and-future-fuels-conference\/wp-json\/wp\/v2\/comments?post=938"}],"version-history":[{"count":1,"href":"https:\/\/www.motorship.com\/propulsion-and-future-fuels-conference\/wp-json\/wp\/v2\/posts\/938\/revisions"}],"predecessor-version":[{"id":940,"href":"https:\/\/www.motorship.com\/propulsion-and-future-fuels-conference\/wp-json\/wp\/v2\/posts\/938\/revisions\/940"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.motorship.com\/propulsion-and-future-fuels-conference\/wp-json\/wp\/v2\/media\/939"}],"wp:attachment":[{"href":"https:\/\/www.motorship.com\/propulsion-and-future-fuels-conference\/wp-json\/wp\/v2\/media?parent=938"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.motorship.com\/propulsion-and-future-fuels-conference\/wp-json\/wp\/v2\/categories?post=938"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.motorship.com\/propulsion-and-future-fuels-conference\/wp-json\/wp\/v2\/tags?post=938"},{"taxonomy":"sponsor","embeddable":true,"href":"https:\/\/www.motorship.com\/propulsion-and-future-fuels-conference\/wp-json\/wp\/v2\/sponsor?post=938"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
