Sjótækni's employees worked on multi-beam measurements in Vestmannaeyjar-harbour for Vestmannaeyjabær, as well as inspecting submarine cables and pipelines between the mainland and the islands. The multi-beam measurements used a remote-controlled survey boat of the type of Otter pro 3 from the Norwegian company Maritime. The boat's multi-beam equipment forms a beam up to 165 ° wide under the boat and thus captures good images of the bottom and what can be seen there.
There are submarine cables for fibre optics and electricity between the land and the Vestmannaeyjar as well as water pipes, and the condition of these pipes must be monitored regularly. When inspecting them, a remote-controlled submarine owned by Sjótækni of the Specter type was used. It is equipped with a high-quality camera as well as positioning equipment and a sonar.
