8 top over lashings
(One lashing / section)

32 top overlashings
(Four lashings / section)

9 top over lashings 16top over lashings
(with lashing / section). (Two supporting beam)

Reasons for the difference:
• Static friction = μstatic = 0.4 • Verticalforce = n × 2 × STF • Dynamic friction = 0.7×μstatic= 0.28 • Vertical force = n ×1,5× STF • Estimated friction = 0.4 • Vertical force = n × 2 × STF • Safety factor fs = 1,1

Reasons for the difference:
• Side acceleration 0.5g • Vertical force = n × 2 × STF • Internal friction considered • Sideacceleration 0.7g • Vertical force = n ×1,5× STF • No instructions for internal friction • Side acceleration 0.5g or 0.6g • Vertical force = n × 2 × STF or n × 2 × 0.5LC • Safety factor fs = 1.1 • Internalfriction considered
