Underwater archaeology task boat
Procurement
Starting point
Underwater archaeology is part of the archaeology and monument preservation department of the Office for Urban Development Zurich. This office sees itself as a service company for the city of Zurich, the canton of Zurich and the surrounding cantons, for which it fulfils the statutory mandate for the archiving, exploration, documentation, excavation and protection of underwater cultural assets.
The underwater archaeology task boats were getting long in the tooth and the old Meier SM58 motor vessel, built in 1986, was replaced by the new acquisition.
Goals
Supply of an aluminium boat with an outboard motor, which can be used for diving and salvaging finds and for the remote sensing of archaeological sites (e.g. boreholes). The boat must be suitable for all weather conditions, able to handle storms and be able to be used safely in the winter.
It will serve in particular as a:
- Means of transport for dive operations and find salvaging, mainly in shallow water areas
- Supervision and monitoring boat for the divers under water
- Platform for sounding and drilling
- Platform for measuring devices for the remote sensing of archaeological sites
- Escort boat for prospecting dives
This required a max. hull depth of 50 cm with a load of 1.2 tonnes; a bow door that can be lowered down to the water; a free work surface in front of the steering position of at least 10 m2.
