Another issue identified by the investigation was that no fail-safe system – involving valve position indicators and gas pressure sensors – had been installed to alert the crew that the valve was failing. <\/p>\n
Wartsila had shipped the main engines to Ferguson’s in early 2017 without such monitoring systems – although it would later fit them as standard on new engines and had fitted them to the smaller auxiliary engines on the ship.<\/p>\n
CalMac’s report suggests that standards body Lloyds Register may have signed off the system based on the assumption that such safety features were fitted on all engines. <\/p>\n
These sensors have now been retrofitted to Glen Sannox and will also be fitted on its sister ship MV Glen Rosa which is due for delivery later this year. <\/p>\n
The valve that failed has been replaced with the new model and CalMac has provided more training to its staff. The ship is not currently operating on gas.<\/p>\n
In a statement CalMac said: “Lessons were learned following the incident in June 2025, and remedial actions taken. <\/p>\n
“The vessel is absolutely safe to operate on LNG, and the decision not to re-gas her following annual overhaul at the beginning of the year was purely due to our desire to get her back in service as quickly as possible.”<\/p>\n
The Marine Accident Investigation Branch has reviewed CalMac’s report and indicated that it is satisfied with the firm’s remedial action. <\/p>\n
Wartsila said client confidentiality prevented it answering questions on why fail-safe monitoring equipment was not fitted on Glen Sannox, or who had access to its service notices. <\/p>\n
In a statement it said: “We are dedicated to sustainability and maintaining the highest safety standards, quality, and reliability for our customers. <\/p>\n
“We work closely with our customers throughout the lifecycle of our solutions and provide technical guidance, updates, and support where relevant.”<\/p>\n","protected":false},"excerpt":{"rendered":"Another issue identified by the investigation was that no fail-safe system – involving valve position indicators and gas…\n","protected":false},"author":2,"featured_media":764595,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[5],"tags":[84,59,56,54,55],"class_list":["post-764594","post","type-post","status-publish","format-standard","has-post-thumbnail","category-business","tag-business","tag-gb","tag-uk","tag-united-kingdom","tag-unitedkingdom"],"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/posts\/764594","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/comments?post=764594"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/posts\/764594\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/media\/764595"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/media?parent=764594"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/categories?post=764594"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/tags?post=764594"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
