What is specifically examined:<\/p><p class=\"font-claude-response-body break-words whitespace-normal\">Quay walls and shore reinforcements: cracks, scouring, joint openings, and material loss, especially in foundation areas that are permanently stressed by ship propeller wash and current.<\/p><p class=\"font-claude-response-body break-words whitespace-normal\">Sheet piles: degree of corrosion according to DNVGL or NACE standards, deformations in the interlock area, damage to tie rods and walings, and wall thickness development compared to the original construction plans.<\/p><p class=\"font-claude-response-body break-words whitespace-normal\">Piers and dolphins: reinforcement corrosion, concrete spalling, crack depth, and biological fouling, which complicates condition assessment and must be removed.<\/p><p class=\"font-claude-response-body break-words whitespace-normal\">Connecting elements: chain links, bolted connections, and welds on underwater anchors, all checked for wear and failure.<\/p><p class=\"font-claude-response-body break-words whitespace-normal\">Documentation: photo documentation by dive section, video recording of the entire survey, findings report classified by urgency.

Underwater components are explicitly included. Anyone who carries out these inspections without a diver inspection does not meet the standard.<\/p><p>In addition, there are the requirements of the Federal Waterways and Shipping Administration (WSV) for facilities on federal waterways, the Ordinance on Industrial Safety and Health for installations requiring monitoring, as well as state water-law regulations. These regulatory frameworks interlock. An operator who is aware of only one source typically has a gap.<\/p><p>The diving work itself is subject to DGUV Regulation 40 and BGR 237. This means: a written diving operations plan before work begins, a qualified diving supervisor on site, an emergency plan, and first-aid equipment at the work site. Clients who commission a company that does not meet these requirements bear shared liability in the event of damage. This is not a theoretical risk. It is established case law.<\/p>\t\t\n\t<\/div>\n<\/div>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-c2e5534 elementor-widget elementor-widget-pxl_heading\" data-id=\"c2e5534\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"pxl_heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<div id=\"pxl-pxl_heading-c2e5534-9578\" class=\"pxl-heading-wrap d-flex\">\n    <div class=\"pxl-heading-inner\" >\n        <h2 class=\"heading-title\">\n            Where TUF International inspects port facilities and waterways                    <\/h2>\n            <\/div>\n<\/div>\n\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-6e9bd31 elementor-widget elementor-widget-pxl_text_editor\" data-id=\"6e9bd31\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"pxl_text_editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<div id=\"pxl_text_editor-6e9bd31-1229\" class=\"pxl-text-editor-wrap d-flex\" >\n\t<div class=\"pxl-text-editor elementor-clearfix\">\n\t\t<p class=\"font-claude-response-body break-words whitespace-normal\">TUF International carries out underwater inspections and maintenance work on port facilities, locks, and hydraulic infrastructure in Germany and worldwide.
