New foundations were installed for equipment in the command room, and one of the two periscopes was replaced with an optronic mast. As a result, the sail had to undergo extensive modifications.<\/p>\n<p>Our QC inspector was tasked with conducting extensive welding and material inspections and providing practical knowledge and support to the execution teams. Critical weld connections specified in the Inspection and Test Plan (ITP) were thoroughly monitored. Inspections before, during, and after welding were performed, and the results were fully documented according to the guidelines of the Navy.<\/p>\n<h3>Expectations<\/h3>\n<p>The 1,400-ton submarines were commissioned in 1987. It is expected that the submarines will remain operational until at least 2025. By that time, a replacement for the Walrus-class will need to be in service.<\/p>\n<div class=\"row w-100 pb-40\">\n    <div class=\"col-12\">\n        <h3>More information?<\/h3>\n        <strong>Projects Department<\/strong><br\/>\n        \n        <a href=\"tel:+31 512 524 008\" title=\"Call us\">\n            <i class=\"fa fa-phone-alt btn-projecten\" style=\"padding: 5px; color: #ffffff;\"><\/i>\n            <strong>\n              <span class=\"text-projecten\">\n               +31 512 524 008\n              <\/span>\n            <\/strong>\n        <\/a>\n    <\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>To extend the lifespan of the Walrus-class submarines by 10 years, the submarines recently underwent a &#8220;facelift.&#8221; Weldmij was responsible for quality control (QC) during this process.
