Charterers

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 usually 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. When predefined thresholds are exceeded, an alert is raised for the operator to act on it. The performance monitoring tool offers the insights needed to manage and improve fuel efficiency, optimize speed, reduce bunker costs through bunker consumption monitoring and delivers GHG emission data for Corporate Social Responsibility reporting.

Our solution offers great advantages

There is a multitude of advantages which are derived from the usage of our tool. Some of which are as follows:

Our product for charterers

How exactly does our product help you as a charterer? Well, first and foremost, through Charter Party Compliance. It allows you to manage Charter Party Compliance of your chartered ships, powered by real-time data and integrated noon-reported data.

The result enables you to:

The Digital Twin

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

Creating the operational profile

Based on several months 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 profiles, and weather statistics using the Digital Twin model. The result is a very accurate prediction of fuel consumption and emissions, enabling you 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, including its impact on vessel trim, by comparing the data reported by the ship to 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 just one (the noon-report) 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 analyze different legs, such as ballast and laden or (preferably) before and after a hull cleaning. The benefit is also that we stay away from the conventional good/bad weather approach. We base our calculations on the actual weather, positions, speed and draft sailed over the voyage instead.

Solving charter party disputes

In some situations, voyage charter party disputes arise. When such disputes occur, you can rely on the data provided by our Digital Twin to build your case and present validated facts. This way, you can solve any charter party disputes with confidence and ease.

That’s why We4Sea is useful for charterers!

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.

Who will benefit from our performance monitoring solution?

Increased performance offers benefits to all parties within the maritime industry. Our solution aims at the following types of companies:
