A digital twin is a virtual representation of a real-world ship. At the core of Syroco EfficientShip, it is used for simulation of ship efficiency and performance in a variety of configurations.
ENERGY AND OPERATIONAL EFFICIENCY
In an era of energy efficiency mandates, emissions reduction and ever increasing uncertainty of energy prices, the digital twin provides an extra level of control over all efficiency parameters. It helps save fuel, reduce emissions and achieve compliance.
The use of digital twin enables an operator to determine specific goals and to let the platform compute the optimal path and recommend a combination of actions (such as engine settings, rudder angle, trim, energy mix, etc.)
The digital twin of the ship is used on board, on shore and in the design office.
- Test scenarios to determine optimum configuration and use
- Build baselines and track performance
PHYSICS AND DATA
The digital twin is built through the assembly of models, each of them representing the physics-driven behaviour of an element of the ship.
The digital twin is an indistinguishable representation of the ship, and especially of her physics-driven behaviour, in specific conditions.
DIGITAL TWIN MODELS
Models are constantly fed, enriched and recalibrated by real-time operational data (IoT from connected on-board systems, operating conditions, external impactful factors, etc.)
Models included in a digital twin include:
Forces created by interaction of the hull with water, waves and swell
Propulsion forces as well as drag, heeling and leeway caused by wind
Efficiency of the engine (diesel, LNG, hydrogen…), propellers, energy consumption
Drag created by the rudder, stabilisers and other appendices
MEASURE AND IMPROVE
The digital twin is used any time a user - at sea, in a fleet centre or in a research lab - wishes to evaluate and predict the behaviour of the ship in a given set of conditions, or to compare actual ship response to expected behaviour.
FUEL CONSUMPTION & EMISSIONS
By running the digital twin on a set of maritime routes and applying weather/sea conditions, Syroco EfficientShip computes precisely the quantity of fuel that will be consumed by the ship during each route segment.
During operation, Syroco EfficientShip continuously monitors fuel and energy consumption and compares actual values with the expected profile, highlighting any deviation.
ENERGY MIX OPTIMISATION
For ships powered by more than one energy source, Syroco EfficientShip produces an ideal energy mix profile based on predicted operating conditions and the overall behaviour of the ship in these conditions.
During operation, Syroco EfficientShip continuously monitors energy consumption and production and compares these values with the planned energy profile, highlighting any deviation and making instant adjustments.
Syroco EfficientShip optimises scheduling to maximise efficiency and performance of each voyage, targeting for example to:
- Minimise delay on schedule
- Minimise sway, roll and surge for passenger comfort and cargo safety
- Minimise time at sea
Syroco EfficientShip builds the best operating schedule profile to maximise efficiency while reaching performance targets, and provides advice during voyage to catch up on targets.
WIND PROPULSION TECHNOLOGIES BENCHMARKING
Syroco EfficientShip builds a digital twin of the ship (existing or projected) and adds to that twin any propulsion device that is being considered: rigid or reefable sails, inflatable or asymmetric wings, kites, rotors, aspirated profiles, etc.
Based on historic weather and sea conditions on maritime routes on which the ship is expected to operate, Syroco EfficientShip runs the digital twin in all possible configurations and operating conditions and produces advanced reports comparing the different options.
