Tecnitas Launches Energy Management Software Tool
Tecnitas, the consultancy arm of Bureau Veritas, has launched a powerful new software tool, E2, aimed at optimising energy usage for both individual ships and across fleets.
E2 is a user-friendly tool which enables shipowners to maximise the gains in energy efficiency and emission reduction which can be obtained through proper use of IMO’s Ship Energy Efficiency Monitoring Plan (SEEMP).
Claude Andreau, head of engineering, Tecnitas, says, “The SEEMP seeks to improve a ship’s energy efficiency through four steps: planning, implementation, monitoring and measurements and self-evaluation and improvement. We hear a lot about energy saving devices which can be fitted and operational savings which can be made, but in our experience shipowners do not know which measures provide the best savings simply because they don’t have the right information to base decisions on. E2 solves that problem by collecting and evaluating all the information needed to make energy saving decisions. It then produces KPIs and benchmarks individual ships or whole fleets against them.”
E2 has different modes. Initially it is used by ships’ crews in the Acquisition mode to monitor, measure and record actual consumption on board in a variety of different cargo and navigation conditions. The software can then calculate the corresponding fuel Key Performance Indicators (KPI’s) and emissions KPI’s.
Two additional modes are available for running E2 software: the Simulation mode and the Benchmark mode, both of them providing decision-making tools for the ship or charterer’s operational management.
In Simulation mode E2 will give access to reference values for a given voyage and to the corresponding calculated reference fuel KPI’s. Data collected in the on-going Acquisition mode can then be compared with the Simulation to deliver the information needed to implement improvement measures and calculate the Yearly Energy Efficiency Operating Index (EEOI).
The purpose of E2’s Benchmark mode is to benchmark, follow up and monitor the energy efficiency performance of different ships within the fleet or of the same ship for different voyages.
The combination of Acquisition mode, Simulation mode, and Benchmark modes mean that E2 software is able to deliver useful information for defining the fleet management strategy for energy efficiency.
The currently available version of E2 software (v1.2) is based on manual acquisition of the input data such as the fuel consumption recorded onboard. A demo version with full capabilities (acquisition, simulation and benchmark modes) but limited time access is available upon request.
Development work is underway on an upgrade which will acquire the inputs automatically through flow meters and GPS. These new capabilities will enhance the accuracy of the data acquisition and will give access to more advanced analyses and diagnosis.
The use of E2 can be licensed either for Acquisition mode only, typically in the context of an individual ship SEEMP, or for Acquisition, Simulation and Benchmark modes, able to improve energy efficiency across a fleet.
