Lot 1: Ålesund Municipality would like to enter into a framework agreement for diving services in Ålesund Municipality. The procurement will cover the contracting authority's ongoing need for diving services, and the diving services will mainly be used for mapping, on-site inspections, new installations (laying new submarine pipelines), and repairs of water and sewage pipelines in various types of material above and below water. It will be necessary to carry out operations from/with a car/boat/ROV (small and large) in order to carry out the assignments in a good way. Aggregate run pumps can be required. If a pigging operation fails, there can be a need for assistance (e.g., disconnection sewage pipelines). The main assignments will be: - Mapping, coordinate fixing, inspections, and improvements of intake pipelines for water in raw water sources and water pipelines in the sea/freshwater. - Mapping, coordinate fixing, inspections, and improvements of sewage pipelines, surface water pipelines, jack legs in sea/freshwater. - Detection of pipelines in sea/freshwater - New installations: Laying new pipelines in sea/freshwater - Minor repairs and replacements of water and sewage installations (pipes, sluices, valves, etc.,) in sea/freshwater (underwater) - Raising and lowering pipelines in sea/freshwater - Installation and maintenance of counterweights on submarine pipelines underwater (sea/freshwater) The tenderer must provide the necessary equipment to carry out the work, including ROV. Some assignments will require the use of a ROV (remote controlled underwater vessel). A small ROV can be used for inspecting mountain lakes. A large ROV can be used for inspections of the sea with depth and current.
