Maritime Air Pollution: Bore’s LNG-fuelled RoLo vessels

24 September 2021

VP, Marine Management

Bore Ltd.

RoRo Tonnage ProviderShipping since 1897

• Part of the Spliethoff Group

• Focus on RO RO tonnage.

• Three RO LO newbuilding in progress at Wuhu Shipyard for the Finnish Paper

Industry.

• Bore charters its vessels on time-charter (TC) contracts to established line

operators.

• Trading area mainly Northwest Europe and Baltic.

– The Charterer pay the bunker !

Design

• Main particulars given by Charterer.

• Design for carriage of paper products for the forest industry.

• RO LO , Hatch cover + stern ramp, box shape cargo hold.

• GAS operation, High efficiency with low consumption, one cargo hold.

• Cargo hold environment control and supervision

• Abt. 7000 Dwt.

• Operating range abt. 3000 miles on GAS.

Focus

• Dimensions, dwt, lay out and model test.

• CFD calculation for hull and separate CFD, Opti Design for rudder and propeller.

• New hull form with low resistance. Not trim sensitive.

• Optimum propeller performance. CPP with ProTouch and Eco Control to enable

accurately synchronized engine speed and propeller pitch.

• Propulsion line optimized with Variable Frequency Drive (VFD).

• No AUX operation at sea.

High efficiency • Low hull resistance and high propulsion efficiency optimized by CFD.

• LNG operation with VFD gives low emissions.

• Waste Heat recovery system with accumulator tank gives high overall

efficiency.

• Cargo hold environment control and supervision take care of sensitive

cargo.

• No lower hold, utilize for LNG tank optimization and flexibility.

• High Main deck strength 6 t/m2 for heavy cargo.

• Container fitted on WD and MD (box stowage), 264 TEU.

Outcome

• L= 121,89 m , B= 21,00 m , Draft = 6,75 m , Dwt= 6900

• Operational speed abt. 13,5 kn , max speed +15 kn.

• Main engine Wärtsilä 8L 34 DF , 4000 kW . LNG operation.

• LNG Pac@ 250 m3 , IMO Type C tank (vacuum insulated) Tank

Connection space , GAS tight enclosure – built on type.

• Waste Heat recovery system (Ulmatec) with accumulator tank take

heat from exhaust gases and cooling water from all system and deliver

heat to consumers abt. 1200 kW automatically.

• Flexible loading and unloading for different types of cargo.

Main deck door gives possibilities for grain cargo.
