Concept design - The Green Dolphin

By Vessels

A new model Handysize bulk carrier concept design – the Green Dolphin, developed by the Shanghai Merchant Ship Design & Research Institute (SDARI) and with coordination with partners DNV and Wärtsilä – meet the needs for fuel consumption efficiency and operational flexibility ready for green requirements in future.
“The focus has been on reducing the fuel consumption while giving owners different options to meet the future expected environmental regulations. The concept design is ready for the owners’ preferred choice, whether that it is to run on heavy fuel oil using emission treatment systems or to switch to low sulphur fuels or LNG,” told Hu Jin-Tao, the president of SDARI.
The Green Dolphin new concept design is a 5-cargo-hold CSR double-hull bulk carrier entirely developed for green environment. The model aims to be fuel-efficient and maintenance–friendly.
“Recognising that there is more to profitable shipping than just compliance, we have consulted widely with owners and yards to ensure that Green Dolphin can be tailored to suit individual operational needs,” said more Hu Jin-Tao.
Designed to meet the requirements of the world's port for Handysize bulk carriers.
The mutual efforts of the design was made by SDARI and DNV. Good performance at also different loading conditions, speeds and sea states.

Ready for scrubber installation
The Wärtsilä 2-stroke low-speed RT-flex50 main engine is Tier II compliant and can usually be retrofitted to dual-fuel engine in the next years. Multiple fuel tanks give the chance for strategic purchasing of heavy fuel oil, low sulphur fuel and distillates. “Design variants are available for fuel switching systems, installation of selective catalytic reduction and exhaust gas scrubbing systems and, in the near future, the use of LNG as fuel” says Giulio Tirelli, Business Development Director of Wärtsilä – Ship Power. “The concept design also includes shaft torque and exhaust gas monitoring equipment to maximise the fuel consumption optimisation possibilities while constantly monitoring emissions,” he adds.
The cargo holds are designed to be with compressed air, power and wash water supply. Wash water maintaining tanks are take part. Wide hatch openings and fully electrical deck equipment make better the loading, discharge and cleaning efficiency so port turnaround time can be made shorter.
“We have achieved a concept design that is not only fuel efficient, safe and robust today, but is also prepared for the future, with the various design alternatives that an owner can select to comply with environmental regulations,” informs Michael Aasland, DNV’s Business Director for Bulk Carriers.
