This photo shows the notheren end of Lerwick Harbour, with the Greenhead base busy with shipping. To the right of the picture is the North enterance, it's a narrower channel than the South one however it is a very busy waterway. In the foreground is the drill and blast barge at work deepening the North channel, this is to allow better access to oil related shipping as well as pelagic trawlers that land to the Shetland Catch processing factory just out of picture on the left.
