IMO Annex 1318:3708.02.28About LASHCONTM: LASHCON is a MS EXCEL based calulation tool for control of lashing-arrangements for semi- and non-standardised cargo. The program is developed byDet Norske Veritas, and is based on the calculation procedures outlined in Annex 13to the Code of Safe Practice for Cargo Stowage and Securing, 2003 Edition.Program assumptions: Reference is made to the User Manual.Input of main vessel data:Vessel Name:Ship Id:Lpp [m]:B [m]:V [kn]:GM [m]:NOTES:0000This version of Lashcon IMO contains the procedures for calculation of accelerations andlashing arrangement as given in theCode of Safe Practice for Cargo Stowage and Securing, 2003 Edition, Annex 13.Following enhancements have been incorporated:1. The range of validity for ship length has been extended down to L=30 m.2. The B/GM range has been extended down to B/GM = 4 by power series extrapolation.APPSPSDeck, high0.1 LSBSBDeck, low0.2 LFwdTween-deck0.3 LFwdAftLower hold0.4 LAft0.5 L0.6 L0.7 L0.8 L0.9 LFP
