Rothesay Dock (West) on the north bank of the Clyde is operated by Clydebank Port Services Ltd. Originally built to supply coal for ships sailing from the Clyde the facility had lain dormant for nearly a decade until the formation of CPS Ltd. in late 2014 and is now re-establishing itself as a commercial port.

With an experienced workforce, ships and haulage are turned around quickly and efficiently to the benefit of all parties involved. The quay has a low water depth of 6.7m, is 185m long and able to accommodate vessels up to circa 12,000 DWT.  A TASCC approved storage shed of 3,000m2, four acres of clean, secure outside storage area, certified 50 tonne weighbridge, and recently constructed heavy lift crane pad allow CPS to offer Rothesay Dock as a flexible ISPS approved facility for companies looking to export and import a wide variety of materials.
