LR SeaSafe

Providing certainty for critical marine calculations.

LR SeaSafe is our loading and stability software. It delivers accurate, consistent results for vital statutory compliance calculations.



Safety and regulatory compliance demand accurate calculations for metrics like vessel longitudinal strength and stability. Rely on LR SeaSafe to deliver this across design, operations and cargo planning for all types of vessels and offshore structures – from passenger ships, oil tankers and gas carriers to semi-submersibles and jack-up rigs.

What we offer

User-friendly and intuitive, LR SeaSafe makes critical data easy to retrieve, analyse and apply. It swiftly creates precise 3D vessel models, derives calculations and produces reports on a vessel or offshore structure’s attributes - ensuring designs and loading are completely compliant.

What are the benefits?

Powered by a common software engine, LR SeaSafe comes in two versions.

LR SeaSafe Professional helps designers, naval architects and shipbuilders rapidly create precise 3D vessel models, derive calculations and produce reports. It ensures designs comply with IMO and national regulations.

Generate manuals and T&S booklets in hours, not days. Build 3D wind models, produce KG/GM limit curves, estimate damage stability – its calculation and simulation capabilities are endless.

LR SeaSafe Onboard works with those 3D models to improve operational efficiency. Captains, officers and onshore staff use this intuitive and simple solution for loading, load planning and other compliance checks. Produce bespoke reports, comply with recent SOLAS loading instrument regulations or exchange data between vessel systems, onshore facilities and other LR software automatically.
