International Energy Efficiency Certificate (IEEC) will be issued to ships 1st January 2023. Your ship will now have an Energy Performance Certificate just like a residential property or when buying white goods. The Carbon Intensity Indicator (CII) is an IMO mandatory rating system for ships. This applies to all cargo, RoPax and cruise vessels above 5,000 GT trading internationally.

The Carbon Intensity Indicator determines the annual reduction factor needed to continuously improve the ship’s operational carbon intensity within a specific rating level.  The performance level will need to be recorded in the ship’s Ship Energy Efficiency Management Plan (SEEMP). Ships rated D or E for three consecutive years will need to submit a corrective action plan to show how the required index rating (C or above) will be obtained.

Put simply, the amount of carbon / ton / mile will have to drop significantly to move up low D or E rating, where A,B&C will be desirable to the supply chain and able to command higher rates.

BigOceanData is supporting shipping targets in a number of ways:

Voyage Planning

The optimal route is now a combination of factors: safe navigation, low carbon intensity, weather routing and all within an agreed time frame. Additional pressures come in the form of ports offering a Requested Time of Arrival (RTA) to minimize port congestion and as ports move into a ‘Just in Time’ environment. BigOceanData offer a solution where optimal routes can be planned and shared with the vessel, the HQ and stakeholders. BigOceanData is readily able to link with 3rd party service providers and all ECDIS systems via RTZ file.

Voyage Efficiency

To maintain the lowest carbon intensity and fuel cost whilst staying on time, the voyage plan had to be optimised first to reduce the need for speed and course changes continually. These changes simply increase cost and carbon. BigOceanData can share the voyage with all stakeholders in real time, keeping all confident that the vessel is on plan to meet the RTA. This shared visibility mitigates the temptation to make those costly speed up changes and keeps the ship below the CII threshold.

Predictive Performance Management

BigOceanData has historic data and modelling of global marine temperatures, when this is combined with a vessels actual voyage history of where, when, how fast and when stationary, the probability of marine fouling can be predicted. Vessels can see when fouling has already impacted performance and efficiency, by which time it’s too late and is costing fuel and carbon. Predictive modelling will enable vessel managers to carry out optimally timed hull scrubs in convenient and cost effective locations.
