Reasons for Implementation<\/h3>\n

\u30fbThe NK-certified nozzle, with its wide spray angle of 170\u00b0, allowed for a reduction in the number of installations.
\n\u30fbThe data, including the spray pattern and other characteristics, was submitted quickly, and the spray videos were easy to understand.<\/p>\n

Challenges the Customer Faced<\/h3>\n

With the mandatory enforcement of SOx regulations for LNG and other gas-fueled vessels, ships that previously did not require fire protection sprinkler systems, such as coal bulk carriers, have been required to comply with these requirements.<\/p>\n

In reviewing approaches for water sprinkling, the customer noticed that using conventional fire protection spray nozzles would require an extensive number of installations to meet the required spray volume. They consulted with us for cost reduction solutions.<\/p>\n

Proposal from IKEUCHI<\/h3>\n

The water volume regulation for sprinkler systems specifies 10 L\/min per square meter for the maximum horizontal projected surfaces and 4 L\/min for vertical surfaces. It is required to evenly spray water over the entire surface of the fuel tank.
\nIn such cases, it is generally necessary to install numerous spray nozzles on the hull to spray water from various directions.<\/p>\n

In contrast, for spraying water from above the fuel tank, we proposed the wide-angle spray nozzle “UZUJP,” which has an extremely large coverage area and abundant spray volume.
\nWe addressed the need for cost reduction by decreasing the number of spray nozzle installations required for fire protection.<\/p>\n","protected":false},"featured_media":0,"template":"","cat_cases":[87],"tag_cases":[307,542],"acf":[],"_links":{"self":[{"href":"https:\/\/www.dry-fog.com\/en\/wp-json\/wp\/v2\/cases\/2704"}],"collection":[{"href":"https:\/\/www.dry-fog.com\/en\/wp-json\/wp\/v2\/cases"}],"about":[{"href":"https:\/\/www.dry-fog.com\/en\/wp-json\/wp\/v2\/types\/cases"}],"wp:attachment":[{"href":"https:\/\/www.dry-fog.com\/en\/wp-json\/wp\/v2\/media?parent=2704"}],"wp:term":[{"taxonomy":"cat_cases","embeddable":true,"href":"https:\/\/www.dry-fog.com\/en\/wp-json\/wp\/v2\/cat_cases?post=2704"},{"taxonomy":"tag_cases","embeddable":true,"href":"https:\/\/www.dry-fog.com\/en\/wp-json\/wp\/v2\/tag_cases?post=2704"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
