Fusion of engine and vessel performance evaluation

Who we are

2018Gold Bite Award with

FoundedAthens and Piraeus

Greece

• Engine performance assessment & fault diagnosis

• Vessel performance evaluation

At we specialize in Performance Management Solutions for the maritime industry.

We use Simulation models, Data analytics & Machine-learning to provide:

For the technical teams in the shore office

providing full overview and assessment

of engines in their vessels and fleet.

Engine Performance Management Suite

Engine Hyper Cube®

Based on an advanced thermodynamic model, calibrated with engine Shop tests and validated with Sea trials.

Core technology

We create a“Digital-Twin”

For each specific engine

The Digital-Twin can provide the “reference” values of all performance parameters (how the engine should be) at any operating condition.

Objectives - engine performance optimization

Sound engine availability and reliability

Energy efficiency Fuel economy Emissions control

Compliance to forthcoming regulations

4

Data accuracy

Operational data accuracy Validation in the system Manual screening in office Training the ship staff and Vessel Managers Measuring equipment – torsion meters, energy meters, flowmeters Reliability of the measuring equipment – servicing and calibration Inline sensors, auto-data loggers - Minimising human intervention

Reference data accuracy Sea trial / shop test / model test reports Updating of the changes – Engine de-rating, sea trials after upgrading

5

Data processing

ISO corrections of monthly performance data

Analyses Comparison against reference data Trend plotting and analyses Alerts for outlying parameters Comparison between similar vessels with same engine configurations

System generated preliminary e-mail reports – for promptness

Guidance on rectifying the abnormal conditions

Apt overview for each level – VM, FGM, Head of business unit

Key Performance Indicators

Performance Report KPIs ME Specific Fuel Oil Consumption (SFOC) Deviation of ME Power demand at reference conditions (%MCR and laden state) Maximum load to which the AE is loaded

Daily Performance Indicators ME Specific Cylinder Oil Consumption (SCOC) Temperatures – Exhaust Gas, Under Piston Space etc. AE Electrical load vs benchmark load for different conditions

Voyage / Periodic Performance indicators Energy Efficiency Operating Index (EEOI) AE utilization (average running hours per day) Average crankcase oil consumption (ltrs./day)

VESSEL OPTIMIZATION

PARIS DASHBOARD / FLEET VESSEL POSITIONS AROUND THE WORLD

OPTIMIZATION- WHY AND HOW?

• BIWEEKLY DETAILED MAIN ENGINE PERFORMANCE REPORTS FROM THE VESSELS.• THE DATA IS UPDATED IN A STANDARD FORMAT AND REVIEWED BY OFFICE AND MAKERS (MHI , EGICS

YANMAR SHIP SUPPORTER).• BASIS ANALYSIS FEEDBACK IS SEND TO THE VESSELS

MAIN ENGINE AND AUX ENGINES -PERFORMANCE ANALYSIS

CASE STUDY 1 :PROPELLER MODIFICATION

• THREE SISTER VESSELS FROM THE SAME SHIPYARD , BUILT SAME YEAR, SAME DEADWEIGHT

• VESSEL PERFORMAMCE OF ONE VESSEL IS LOWER THAN THE OTHER IN TERMS OF SLIP, SPEED AND FUEL CONSUMPTION

• PROPELLER BLADES TRIMMED

• RESULT: THE LIGHT RUNNING MARGIN INCREASED AND THE OPTIMUM FUEL CONSUMTPION AND SPEED WAS ACHEIVED

PERFORMANCE OPTIMIZATION MEASURESCASE STUDIES

PROPELLER BLADE TIPS MODIFICATION OUTLINE POWER CURVE AFTER MODIFCIATION OF PROPELLER

CASE STUDY 2 :OPTIMIZING PERFORMANCE BASIS WEATHER CONDITIONS

• VESSELS ARE ENROLLED IN THE WNI PLATFROM. THIS PROVIDES ON A DAILY BASIS FEEDBACK ON THE SPEED, CONSUMPTION AND WETAHER CONDITIONS

• WEATHER CONDITIONS AND OCEAN CURRENTS ARE ANALYSED IN THE OFFICE AND APPROPRIATE INSTRUCTIONS ARE SEND TO THE MASTER.

• IN CASE ANY TYPHOONS OR LOWS ARE DEVELOPING IN THE AREA, TIMELY ALERTS ARE SEND TO THE VESSEL DEFINING ROUTE DIVERSIONS OR SPEED ALTERATIONS ( STOP / DRIFT )

• RESULT: VESSELS HAVE ACHIEVED THE DESIRED RESULTS AND PERFORMANCE DURING THEIR VOGAYAGE

CASE STUDY 3:TRIM & DRAFT OPTIMIZATION

The trim and/or draft of the ship affects the hull resistance and hence the fuel consumption. By actively planning cargo loading and thereby optimizing the trim and draft, one can save fuel and reduce the emissions accordingly.

Trim vs Speed table for a Post Panamax vessel built at Oshima Yard

Red Cells – Indicate Trims which are unfavorable to the vessel’s speed and ME consumption (More than 2.0 % rise in BHP needed for same speed)

Yellow Cells – Indicate Trims with an increase below 2% in Fuel consumption

Green Cells - Indicate trims which are favorable for speed vs ME consumption characteristics
