We4Sea offers solutions to measure, manage and report on fuel consumption and related emissions of your chartered vessels – in real-time, without investing in on-board monitoring equipment.

Monitoring the fuel-efficiency of chartered ships is difficult. Charterers need to rely on noon-data, reported once a day.  Noon-data is known to be a lagging indicator characterized by high potential for human error due to manually observed and reported average values. Also, it is not real-time, and by the time you realize that the fuel consumption is increasing, the moment to act on it has already passed.

Managing fuel consumption will become increasingly important, for reasons of competitiveness and due to stricter emission regulations.

Our monitoring platform allows charterers and cargo owners to follow the performance of ships in real-time, without investing in on-board monitoring equipment.

Fuel efficiency and emissions are presented in real-time. If predefined thresholds are exceeded, an alert is raised for the operator to act on. The performance monitoring tool offers the insights needed to manage and improve fuel efficiency, reduce bunker costs and  enables reporting of GHG emissions for Corporate Social Responsability.

Our solution offers great advantages:

Our products for charterers include:

Charter Party Compliance :  Managing Charter Party Compliance of chartered ships, powered by real-time data and integrated noon-reported data.

The result is a enabling you to:

Bunker Management:  Managing fuel efficiency of owned or chartered ships, fully independent from Noon-report or on-board sensors.

We4Sea can provide you with an unique and scientifically supported, algorithm based Digital Twin of every seabgoing ship. We use 80+ characteristics of the ship to create a Digital Twin model, which is fed with real-time position and weather data.  The result is a very accurate calculations of fuel consumption and emissions enabling you to:

Pre-charter Assessments,  to establish the Speed / Consumption curves and historic operational profile on any  vessel prior to fixing it.

Based on several month’s of historic data, We4Sea is able to deliver an operational profile stating vessel speed profile (SOG/STW), calculated fuel consumption and CO2 emissions,  per day and per voyage, engine load profile, weather statistics using Digital Twin model

The result is a very accurate prediction of fuel consumption and emissions enabling you to:

Speed Loss and Fouling Assessments,  to establish the Speed Loss and impact of hull fouling of any voyage.

We4Sea can  investigate the magnitude of speed loss due to bad weather, poor maintenance and hull fouling by comparing the data reported by the ship to a digital modelled version of the ship, the Digital Twin. The voyage will be ‘re-sailed’ using the Digital Twin in various configurations, yielding both the extra fuel consumption due to hull fouling and poor maintenance, as well as the speed the vessel would have been able to sail were she in good condition. Using historic AIS, we use up to 480 datapoints per day instead of 1 (the noon report) with 6hr snapshots on weather as used in conventional CP assessment reports.

The Digital Twin concept has been used in many disputes to calculate the “speed loss” and “fuel consumption increase” due to inefficiencies in the ship for the Time Charter period.

This has proven to be a very strong evidence in claims, to support arguments for underperformance and off hire. The case becomes even stronger if we can analyse different legs, such as ballast and laden or (preferred) before and after a hull cleaning.

The benefit is also that we stay away from the conventional Good/Bad weather approach, instead we base our calculations on the actual weather, positions, speed and draft sailed over the voyage.

Performance monitoring

Our performance monitoring platform allows cargo- and ship owners to monitor the performance of their (chartered) ships. Monitoring the vessels carrying your goods has never been an easy task, since the ships’ noon reports were the only way to keep track of ship performance – until now. Our digital performance monitoring platform allows for the remote monitoring of ships in the best way possible, giving you direct and real-time insight into vessel performance and critical parameters.

How performance monitoring works

To accurately monitor ships, we create a Digital Twin. The Digital Twin is a digital replica of the ship , virtually representing it precisely the same as her real-life counterpart. This Digital Twin is fed with data of all  parameters that influence performance. To illustrate, we’ve listed a few of those parameters below.

Using these parameters, the instantaneous performance of the ship and each of its components is simulated and displayed. This performance is the achievable performance of the ship, when sailing in perfect technical condition, i.e. no fouling or technical issues. Fuel consumption and emissions are presented and can be benchmarked with actual on-board measurements or noon-reported data for precise and accurate insights. Any difference between the two are inefficiencies, such as hull-fouling, or incorrect reporting. Using this data, the performance manager can take informed decisions on the need for maintenance, or correct reporting issues.

Of course, all of this data is displayed in a useful and practical manner. This means that the remote monitoring of ships provides previously unheard of opportunities for more efficient planning and active performance monitoring.
