In the summer of 2022, Héðinn undertook the task of dismantling and transporting meal silos in Grønehaugen, near Egersund on the southwest coast of Norway. Each silo weighed 80 tons, stood 30 meters tall, and had a diameter of 7.6 meters. They were transported on a barge across the fjord to Ryttervik, where they were converted into fish oil tanks.

Large storage tanks have been on Héðinn’s project list ever since the company’s early years. In 1927, Héðinn and Hamar undertook the largest project that Icelandic machine shops had taken on up to that time: the construction of oil tanks for Shell HF’s new oil storage facility, which was built by Skerjafjörður. The work began in June that year and was nearly completed by December. Between fifty and one hundred people worked on the project daily. Three large oil tanks and several smaller ones were erected. All the rivets in the tanks were air-hammered, and the seams of the iron plates were caulked. “Modern sealing air tools” were used, according to contemporary sources describing these extensive works.

Héðinn has erected meal silos all around Iceland — in Fáskrúðsfjörður, Eskifjörður, Norðfjörður, Seyðisfjörður, and Akranes — in addition to numerous silos in Norway.
