Vessel Decommissioning - Sand Swan

April 2021

Vessel Decommissioning

Dales Marine Services Ltd secured the contract to undertake the decommissioning of Sand Swan, a Suction Dredger built in 1970, which had a carrying capacity is 1944 t DWT and a draught of 3.5 meters. Her length overall (LOA) was 66.6 meters, and her width 12.53 meters. The aim was to recycle as close to 100 per cent of the vessel as possible.

Dales Marine Services carried out vessel decommissioning at its licenced dry dock in Leith. Dales has a quayside adjacent to its yard and workshop that can take vessels over 100m long and drafts up to 7m.

Vessel Decommissioning - Sand Swan

Scope of Work

  • Removed all the flammable materials in the accommodation structure
  • Mechanically removed machinery and parts
  • While still afloat, Dales prepared the steel to allow for more productive use of the crane and reduce the amount of time in the dry dock. This was done by strip cutting as much as possible whilst ensuring the vessel’s watertight integrity
  • Using a Tug, the Sand Swan was then manoeuvred into the dry dock
  • Two cranes (90t & 45t) lifted the steel from the vessel onto a laydown area ready for collection
  • Dales made the final series of cuts, and the remaining steel was lifted from the dry dock, processed on the laydown area and made ready to be collected for recycling
  • Dales Marine Services is regulated in accordance with SEPA and the EU Commission for the end of life vessels
  • Our aim is always to recycle as close to 100% as possible
