WLT has access to a 24 hour maintenance service to carry out repairs during calamities. The repairs can take place on location or in the Bergambacht workshop. In the former case, WLT also handles the dismantling/assembling and transport of the equipment.

WLT not only repairs its own equipment, but also equipment from other manufacturers. This includes folding stairs and fall protection systems, tanker loading arms and equipment for marine loading.
