Initial situation

Khasab is a city in an exclave of Oman bordering the United Arab Emirates. It is the local capital of the Musandam Governorate, and has frequently been dubbed the "Norway of Arabia" because of its extensive fjord-like craggy inlets and desolate mountainscapes. The new built coast road allows fast access from the United Arab Emirates, making Khasab a popular weekend destination for people living in the Emirates. To build this road, massive cuts had to be made in the rock walls comprising of thickly bedded to massive limestones. As a result, the street runs along steep and sometimes vertical rock cliffs of up to several hundred meters height- which in turn leads to a massive risk of falling rocks for road traffic.

Description

Main geological unit comprises of thickly bedded to massive limestones of Cretaceous age. These limestones form cliffs of up to several hundred meters height above the coastal road. In order to protect the existing coastal road from Khasab to Tibat from rockfalls and the associated risks and consequences for the traffic a mitigation concept has been worked out. The team from the construction company Artusa Oman installed rockfall barriers over a length of about 1.5 kilometres. Their energy absorption capacity ranges from 1000 kJ up to 8000 kJ. The post were up to 9 meters high, which was particularly challenging for the installation teams. Nearly all locations were difficult to access. For this reason, many posts and nets were installed using a helicopter.
