Lloyd's Register (LR) launched RouteFlex, a containership stowage application designed to recalculate stowage limits when weather, routing, or voyage plans change. [^1]

Lloyd's Register (LR) and the Marine Design and Research Institute of China (MARIC) secured Approval in Principle (AiP) on 2026-09-03 for a new 114,000 DWT product and crude oil tanker designed to accommodate future conversion to LNG, methanol, or ammonia. [^2][^6] Lloyd's Register said the RouteFlex approach could release additional cargo capacity while retaining required safety margins. [^3] RouteFlex applies metocean-based factors to individual voyage legs, allowing operators to assess container stacks against expected conditions on each leg rather than a single worst-case assumption for the entire route. [^4]

RouteFlex can reassess existing stowage arrangements after a diversion and split complex voyages into separately optimized legs. [^5] The AiP was announced at SMM 2026, a maritime trade fair, on 2026-09-03. [^7] The design concept was reviewed against Lloyd's Register's July 2026 class rules and regulations, including requirements for ships using gases and other low-flashpoint fuels, alongside relevant IACS Common Structural Rules for oil tankers.
