Vessel Performance Application

1.1.1   Introduction

The KONGSBERG Vessel Performance Application (VP) bridges the gap between vessel and shore, enabling data driven decision making on both sides.

The application gives onshore and onboard personnel the same operational picture in order to increase operational awareness. Onboard the operator is provided real-time data and performance KPIs, benchmarked specifically for the vessel. Onshore the same data is combined with real time and historical data for the whole fleet, providing the full picture. Together, both applications support optimized vessel and fleet operation, equipment use, and reduced time spent on reporting.3 PNG.png

1.1.3   Functions

Level 1 Basic

Function: Fuel Performance

1 PNG (1).png Fuel performance is the overall performance indicator and is split into sailing performance (when speed is above 4 knots) and passive performance (when speed is below 4 knots). Sailing performance display the current fuel usage in consumption pr distance unit for example l/nm. Passive performance display the current fuel usage in consumption pr time unit, for example l/hr, and describes ship performance while in stationary type operations.          

Function : Fuel Benchmarking

2.png

Allows the initiation of a benchmarking session, and the system records the current fuel performance for the vessel. Any change to how the vessel is operated will feed information to the benchmark and display the result to the crew. The benchmarking can be stopped to receive a summary of total savings.

Function: Operational Mode Detection

3.png

Operational mode detection shows the current ship mode, automatically detected by the system. For specific vessel types extra operations may be added, such as trawling, embarking, or anchor handling, and this may require additional interfaces.

Function: Emissions Monitoring

4.png

Emissions monitoring indicates current real-time emissions calculated from class approved fuel-factors, or through table interpolation based on engine load (Note: Requires engine shop test data). Emissions of CO2 is currently supported.

Function: Leg And Voyage DocumentatioN

5.png

Leg and voyage documentation automatically identify legs to be used for comparison to previous legs and related performance indicators. Legs are automatically detected based on the vessel speed. Voyages are initiated by having the crew to press a button in the user interface.

Level 2 standard

Function: Baseline benchmarking

Baseline benchmarking add comparison between the current fuel performance against the baseline generated from historical usage. Sailing performance is compared to baseline per operational mode and per speed step (1 knot). Passive performance compares the current fuel usage in l/hr against the historical usage in the same operational mode (at port, dynamic positioning, etc.).

After collecting 8-12 weeks of data, the baselines are generated by the KONGSBERG analysis team, and sent to vessel owner for approval. Depending on the modules in scope, there are several baselines for approval, such as the sailing efficiency (l/nm) and passive efficiency (l/hr). After the baselines has been agreed and installed, all vessel operations are compared against the baseline and the performance is displayed to the crew in real-time onboard and historically on the web portal.

Function: Weather Resistance Indication

8.png

Sea Margin indication estimates the effect of external forces, mostly influenced by wind and waves. Understanding the added resistance is important for the trim and speed optimization, and valuable as documentation when for instance the energy consumption was higher than normal for a leg. Weather data can be further analysed on the Fleet Web Portal

Note: Requires wind sensor and motion sensor data

Function: Engine Performance

9.png

Engine performance shows the total Specific Fuel Oil Consumption (g/kWh) for all engines, split into different fuel types, and indicates how efficient the engines are running. The SFOC is then compared against the baseline for same energy production and operation, and this will indicate if the ship is currently running more engines than needed (engine loads closer to MCR is more energy efficient). Comparing SFOC to historical data can give an indication of engine health.

Note: Requires engine shop test data.          

Function: Speed Optimization

10.png

Speed optimization uses distance to destination for just-in-time arrival, and estimates consumption, cost and time difference for different speed profiles. There is a visualization of the relationship between propulsion power usage and speed, this can help the crew understand potential savings by reducing speed and to compare current performance against historical usage.

Note: Requires NMEA RMB string from Ecdis

Function : Operational Cost Monitoring

11.png

Operational cost monitoring allows the crew to log cost data and gives an indication of cost per hour and nautical mile for machinery and propulsion maintenance/service cost, fuel cost and  missions(where applicable) cost. Manual input of cost per unit and fuel is required. Note: Only propulsion and engines/generators. Other equipment can be included on request.

Note: Requires running signal on monitored equipment

Level 3 Premium

Function : Electrical balance

12.png

Electrical balance displays available power consumption readings from different subsystems in the switchboard, typically propulsion and accommodation.

Note: Does not include SWBD hw. Normally only propulsion and generator load is available in PMS.

Trim Optimization

13.png

Trim optimization shows potential savings by adjusting the current trim, by comparing the required propulsion power in current condition against various trims configurations from historical data. Using the best trim is an important factor in getting the lowest hull resistance, and thereby reducing energy consumption and emissions. The module advices the crew to try different trim settings, and the system automatically learns the best trim for a given speed and draft.

Note: Requires torque-meter or KM propulsion.

Propulsion Performance

14.png

Propulsion performance visualize the efficiency of the propulsion system, calculated from the relationship between propeller power and shaft power. The current efficiency is compared against baseline for current speed and weather condition. In addition to propulsion efficiency, the calculated propeller slip is displayed to indicate ineffective propeller settings.

Note: Requires KM propulsion. Other propulsion systems on request.

Hull Performance

15.png

Hull performance aims to help the ship owner to plan hull cleaning by estimating added resistance in hull due to marine growth.

Note: Available from 01.01.2021

Requires torque-meter or KM propulsion.

Vessel Performance Energy / Emissions Budget

21.png

Energy Budget allows you to benchmark each vessel's fuel consumption and emissions against a target, on vessel as well as fleet level. This can be viewed as a monthly trend compared on a given time interval. Energy budget is a useful feature for proving to a customer or a regulatory agency that the vessel operates within agreed-upon consumption and emission limits.
