Case Study -1

BOW MODIFICATION ANALYSIS

• Vessels : 6750 TEU & 13119 TEU containers

• Scope of assessment : Container vessels underwent bow modification for fuel savings and economic sailing where the actual operational fuel savings was checked.

• Conclusion : The savings in the fuel was not found justifying the investment on the modification and the owners dropped the plan to extend bow modification to further vessels. This was a major decision for the owners before a huge investment.

PAINT STUDY *

• Vessels : Containers & Bulkers

• Scope of assessment : A special paint was applied for one of the sister vessel after DD on the claim for a lesser hull fouling

• Conclusion : The specially painted vessel performance was compared with her sister vessels performance and found the claim to be valid and ROI was good

* Paint study is typical example. Similar studies were carried out for PBCF installation, silicon coating on propeller etc.

REPORTING ISSUES

• Vessels : Containers

• Scope of assessment : To access the common reporting errors and rectify

• Conclusion : A major reporting error was found in reporting the fuel* Helped the owners to identify an issue in calibration of flow meters

* The reported data was analysed using the data monitoring tool and found a mismatch between the reported FO and ROB against the bunker data.

PBCF FUEL GAIN ANALYSIS FOR BULK CARRIER

• Vessels : Bulk Carrier

• Scope of assessment : Study was conducted to understand the fuel savings from PBCF installation.

• Conclusion : It was identified that the vessel has gained 4.8% on Fuel oil consumption after the PBCF installation.

UNDER PERFORMANCE CLAIM VERIFICATION

• Vessels : Bulk Carrier

• Scope of assessment : Evaluate the vessel performance in view of the underperformance claim for the vessel. The vessel underwent a propeller modification to increase the light running margin.

• Conclusion : On evaluating the reported data after the propeller modification, It was evident that the light running margin has increased and the underperformance claim was true. The analysis showed that there was a reporting error in the   Power, which was later confirmed by the vessel.
