As container ships grow in size they can be susceptible to excessive rolling during voyages which can put containers at risk. Better understand the roll limits of your ship before transit and make better routing decisions during voyages using RDA Notation and RollRight software, to give you and your crew confidence at every roll angle. 

Roll Design Assessment (RDA) Notation 

Developed by LR to address the rising impact of excessive rolling, RDA notation gives you a ship-specific assessment of roll behaviour and defines safe rolling limits under anticipated loading and sea conditions. RDA drives operational readiness by enabling early crews alerts and trigger measures to protect cargo. 

RDA helps you: 

  • Operate profitably through better roll-risk mitigation planning  
  • Define safe rolling limits based on ship design and anticipated sea states 
  • Improve operational readiness by modelling vessel-specific roll behaviour 
  • Alert crew to take proactive measures and adjustments to avoid roll events 
  • Reduce risks of container losses by identifying hazardous roll conditions in advance 

RollRight 

Minimise roll risk with LR RollRight, the onboard predictive intelligence tool  

RollRight gives your crew early warnings, visual guidance and predictive insights to help anticipate and avoid dangerous roll conditions. RollRight is class-approved and integrates seamlessly with your fleet to help crew make better, safer decisions during voyages. 

RollRight: 

  • Alerts with visual guidance to reduce predicted roll risk 
  • Assesses specific roll vulnerabilities based on real-time sea states  
  • Improves onboard decision making with early warnings and actionable insights 
  • Supports your crew with route-specific recommendations to avoid dangerous roll conditions 
  • Easily integrates into your existing onboard systems, and meets LR class requirements
