Investigation updates: fv Nancy Glen

Updates on the investigation of UK registered fishing vessel Nancy Glen (TT100), which capsized in Loch Fyne on 18 January.


Update, 9 February 2018

We have now competed our underwater survey of the wreck of Nancy Glen, which despite the depth and poor underwater visibility has been largely successful. We are now in the process of assessing the extensive quantity of data collected, which is taking some time. We are very conscious of the need to come to a decision as soon as possible as to whether or not the MAIB intends to raise the wreck as part of its investigation. However, we do not expect to make an announcement on this until after the weekend.

News story, 7 February 2018

The Marine Accident Investigation Branch (MAIB) is investigating the capsize and loss of the fishing vessel Nancy Glen and why, tragically, two of the crew did not survive.

The wreck of Nancy Glen is lying at a depth of over 140m. Following a multi-beam sonar survey of the wreck conducted by Northern Lighthouse Board vessel Pharos last weekend, the MAIB has contracted KML to carry out a more detailed survey of the wreck. KML’s vessel Severn Sea is on scene, and has carried out a side-scan sonar survey of the wreck. This has provided us with 3-dimensional information on how the wreck is lying on the seabed and potential obstacles such as wires or nets that could be hazardous to remotely operated vehicle (ROV) operations. The ROV is fitted with cameras, used to collect important evidence as part of our investigation. ROV surveys commenced on Wednesday 7 February, but progress has been slow due to low underwater visibility of around 3 metres and the risk of the ROV becoming snagged on wires and ropes around the wreck. Our inspectors are on board, and are keeping the families updated on progress.
