Fuel consumption optimization via weather routing

Overview of engineering applications of met-ocean modelling in ship/offshore/marine engineering overview of engineering applications of met-ocean modelling in ship/offshore/marine engineering
- The lecture provides a general overview of the numerical models and methods in use today for the prediction (forecast) and backward reconstruction (hindcast) of wind generated ocean waves.
Overview of the basic equations governing wave models at mesoscales
- Available dataset from the major providers of wind-wave data generated with these models, both forecast and hindcast data, are listed and discussed.
Met-ocean modelling: operational forecast and hindcast procedures
- The strategic importance of simulating the behavior of the ship in real conditions with met-ocean (wind-wave) data that represent a given geographic area the ship is sailing through is addressed.
Simplified models for seakeeping and added resistance of a ship in waves
- Wind and wave data are then used to assess the performance of a ship on a given route, in terms of ship motions and added resistance.
The lecture doesn’t foresee any industry testimonial intervention but two practical applications developed in the past at UniTS, related to two distinct end users, will be discussed.
Aims and intended learning outcomes
- Understanding of key aspects related to the adoption of actual sea states for ship routing and/or operational efficiency at design stage.
