Mooring Line Systems for Tanker Vessels – Current Standards in Analysis and Design Compared to Real Life Data

By: Rune Iversen, William Bruin
Design and analysis of moorings of tanker vessels have traditionally been approached from two sides: from the vessel side, regulated by classification societies and with proposed guidelines from OCIMF, and from the land side, regulated by local codes and standards.
