1. INTRODUCTION From January 1 2013, IMO has adopted mandatory reduction measures for CO2 emission

for all ships. Apart from the emission reductions it also leads to a significant cost saving for

the shipping industry by energy efficiency. Energy efficiency improvements can give cost

savings of 5 – 15 % and bring down greenhouse gases. In the process a fuel savings is also

possible.

Under IMO MARPOL 73/78 Annex VI Reg. 22, all ships must have an International Energy

Efficiency Certificate (IEEC) and requires via IMO MEPC 62 (July 2011) a Ship Energy

Efficiency Management Plan (SEEMP) to be mandatorily implemented by 1st January 2013.

This establishes a mechanism to improve the energy efficiency of a ship in a cost-effective

manner. The SEEMP also provides an approach for shipping companies to manage ship

and fleet efficiency performance over time using the voluntary Energy Efficiency

Operational Indicator (EEOI) as a primary quantitative monitoring tool. The EEOI enables

operators to measure the fuel efficiency of a ship in operation and to gauge the effect of any

changes in operation, e.g. improved voyage planning or more frequent propeller cleaning,

or introduction of technical measures such as waste heat recovery etc.

IMO Circ. 684 section 6.1 recommends that monitoring should be carried out as far as

possible by shore staff in order to avoid unnecessary administrative burdens on ships' staff.

1.1 Brief Description of Viswa Energy Efficiency Management System (EEMS)

Viswalab, recognizing that shore staff is also heavily burdened, has developed this EEMS

Instrument which automatically, consistently and continuously, collects all relevant data

for electronic logging. It gives continuous on-line results saving a lot of time and effort.

While manual entry of data for purpose of calculating EEOI is permitted by IMO, it is

obvious that the numbers will always be suspected particularly by outside agencies. It is

envisaged that EEOI will be used for important considerations with regard to KPI, charter

rates, sale and purchase of ships, monitoring performance by ship staff, monitoring

performance of various energy efficiency technologies etc. It is therefore imperative that

the system of data collection and the computation are fully automated and function

independent of human interference.

There are systems available in the market costing a minimum of $50K and up to $150K. A

basic system which takes care of all important parameters contributing to EEOI should be


adequate to meet both the IMO regulations and the other commercial and operational

requirements

Viswa Lab offers such a system at a sensible cost and with built in provisions to add

features for any additional future requirements. The two other important aspects are the

very brief installation time and the rugged tamper proof instrumentation system. The

system is also designed to be an effective management tool to monitor and improve the

vessel/fleet performance.

The following details are available from the system

1. EEOI trending with a vessel

2. EEOI trending within a fleet

3. Specific Fuel Oil Consumption trending

4. Slip (hull fouling, hull cleaning) trending

5. Trend of Distance Travelled-Fuel Consumed-Speed-Cargo Carried

6. Daily ROB charts So far the marine industry has been used to manual log books form of intermittent data

dependent on watch keeper entering the log books once every 4 hours. This requires a lot

of manual analysis work onboard with shortage of staff. It needs bulky log books being

transferred to the office and extra staff to re-enter data and analyze it on an accuracy of a

few percent basis.

With the Viswa EEMS instrument we introduce to the marine industry an electronic

assistance to gather all the data automatically in a continuous real time manner, without

burdening either the ship’s crew or the office staff and save on the manual dispatch of log

books and storage problems. It also saves on large amounts of data being transmitted

unprocessed to the office, focusing only on the end onboard calculated results.


1.2 Viswa EEMS Saves time, effort, money and can help make shipboard decisions on

the spot

This data can be analyzed to more accurate decimal levels of a percent according to your

specifications. In addition, it is possible to evaluate these data across a fleet of ships quicker

and more accurately, without the element of human error at every stage of the old manual

process. Comparison with sea trials data with clean hull can be plotted automatically to

define current state of ship’s efficiency.

1.3 Types of EEOI Reports Available

Nine different types of report on EEOI and CO2 Emission can be generated and compared

across a fleet. The reports are:

• EEOI Voyage Basis Report for a Specific Voyage

• EEOI Port to Port Basis Report

• EEOI Rolling Average Report for all Voyage

• EEOI Plot of Individual Voyage against Voyage Number

• EEOI Rolling Average of 6 Voyages

• EEOI Rolling Average across a Fleet

• CO2 Emitted for All Voyage

• CO2 Emitted Tonnes/ Mile for Laden All Voyage

• CO2 Emitted Average Tonnes/Day All Voyage

1.4 Other parameters and trending captured are:

• SFOC (Specific Fuel Oil Consumption)

• ROB (Remaining Oil on Board)

• Vessel Tracking by Latitude & Longitude Position from GPS

• Weather condition

• Total fuel consumed for a specified period/voyage


1.5 Additional Points

• The trend graphs can be customized as required

• Full range of automated report generation on EEOI

• Monitoring of SFOC of main engine

• Option to add additional sensors and functionality in future

• Data in .csv format can be easily adapted to any other type of data analysis software.

1.6 What is measured?

• Fuel Consumption from the flow meter

• Shaft RPM

• Shaft Torque & Power

• Ship’s speed

• Main engine SFOC

• GPS Position of vessel

• Fuel Quality

• Time and event related to a voyage – the system uses UTC time from GPS time stamp


2. OUTLINE OF THE SOFTWARE

2.1 Automatic Data Logging System

The Automatic data logging system runs without any intervention from the user in the

background. It has a failsafe system to continue working in the event of a blackout using

back up battery.

2.2 User Input by Ship Staff to Capture Events Occuring

Events occurring related to a voyage which cannot be captured automatically or where a

specific sensor is not available and improvised by manual input i.e. START/END OF

VOYAGE, FULL AWAY, EOP, draft, cargo quantity, added bunker etc.

The sequence of this program is designed keeping in mind the flow of events that happens

from the start to end of a voyage.

2.3 The User Interface at the Office for

Information

This is the software installed in the office. Once the ship staff enters phase 2 data the

program generates a daily file after mapping the information with the automatic data

acquisition system. Fuel cons

calculated and assigned for the day and leg of the voyage. This data file is sent to the office

through email attachment by the ship staff. If the ship is connected to the internet this

process can be made automated where after generating the data the program automatically

sends out the data to the office.

Data sent from the ship is downloaded from the email by the software and uploaded into

the database. The database contains data from all sh

3. OUTLINE OF HARDWARE

Sensor signals from Bridge are converted and transferred to engine room server using the

local area network of the ship. Signals from sensors within the engine room are directly

connected to the data acquisition unit by screened signal cable. Data is logged every second

and saved every hour in the storage system. This helps to reduce the volume of data. This is

again further processed to generate daily data summary automatically and transmitted

ashore by email attachment. The file size of such attachment is less the 7kb and thus very

minimal transmission cost. Currently the equipment installation, servicing and training is

provided in the port of Singapore. Other ports can be considered on request.
