Mission-ready optimisation for crewed and uncrewed maritime operations.
Mission Optimisation Layer (MOL) helps planners, operators and connected systems identify mission options that extend endurance, preserve reliability and improve mission effectiveness under changing operational conditions.
our technology
AI designed for navigational intelligence
Theyr Defence Systems develops MOL, a Mission Optimisation Layer for complex maritime defence, security and autonomous operations.
Derived from the T.VOS optimisation engine, MOL evaluates competing mission variables in each computation, helping planners, operators and connected systems evaluate operational trade-offs across time, energy, reliability, safety and mission effectiveness.
The result is not simple route planning. It is a mission-optimisation layer that can support decision-making as platform state, environmental conditions and operational priorities change.
MOL
MOL is designed to evaluate multiple mission variables simultaneously including platform state, environmental inputs, mission constraints, timing, retained energy and reliability.

Surface options that preserve energy and reliability, enabling longer time on mission and greater operational persistence.

Evaluate hundreds of thousands of mission options to reveal clear trade-offs across endurance, timing, exposure and navigation confidence.

Connect with mission systems, autonomy stacks, WECDIS environments and command workflows.

Balance mission effectiveness, safety, endurance, timing, exposure and navigation confidence in a single computation.
How it works
MOL
MOL is a modular, AI-powered optimisation engine designed to evaluate competing objectives and operational constraints in a single computation.
It combines metocean data, navigational information, digital vessel models, mission parameters and customer inputs to generate optimised mission and voyage options. Helping planners, operators and connected systems understand the trade-offs between time, energy, reliability, safety and mission effectiveness.
DEPLOYMENT MODES
MOL supports mission optimisation across offline, intermittent and fully connected operational conditions.
Case Study
Enhancing NOMARS
As the defence subsidiary of Theyr Ltd, Theyr Defence Systems is building MOL on the proven T.VOS optimisation foundation, including autonomous vessel programme experience from NOMARS.
“After substantial benchmarking with existing solutions, Submergence recognised the benefits of the T-VOS™ optimisation engine. This supports our quest to improve the operational efficiency of Marine AI.”
