Loch Striven (Scottish Gaelic: Loch Sroigheann) is a sea loch adjoining the west side of the Firth of Clyde just north of the Isle of Bute, where it forms a narrow inlet about 8 miles (12 km) long extending north into the Cowal peninsula. During times of recession in shipping, the loch has been used as a sheltered anchorage for laid-up vessels such as large oil tankers.The Danish shipping company Maersk used the loch for cold layup of some of its vessels namely the b- class vessels in its fleet.
