  - Polish Maritime Research - Year 2012

  The paper deals with a removable steel inner gate which was designed to separate two parts of a dry dock of about 70 m in width and 380 m in length. The gate allows for independent assembly of ship structures in two separated parts of the dock. The fore part of the dock can be flooded while the after part is dry. Tthe gate was designed by IDEK Company Ltd in 2011 and it was soon constructed and used by CRIST Shipyard in Gdynia.

  Docking operations of ships require a response assessment to ensure structural and personnel safety. Environmental loads and improper ballast adjustments are the main threats to the docking operations. They can cause severe structural damages and stability loss to a floating dock system which includes a floating dock and a docked vessel, even if the velocities of the dock and the vessel are very low during the docking process....

  We report the results of recent field measurements of seawater thermohaline structure and transparency carried out in early summer 2014 in Puck Bay. Near-bottom, less saline waters occurred almost in the entire study area. Their occurrence in the shallow part of Puck Bay was accompanied by an increase in the seawater transparency. The most likely explanation of these observations is a submarine fresh groundwater discharge.
