Wärtsilä has supplied the open loop scrubber systems for four new 45,000 dwt Ro‑Ro ships for Italian owner Ignazio Messina & Co.
The vessels will burn residual fuel oil, and the scrubbers ensure that the 0.1% fuel-sulphur content emission regulations can be met. These vessels are the first of their type to gain the RINA’s Green Plus notation, and the Wärtsilä open loop scrubber systems are all MED certified.
The Jolly Diamante, owned by Ignazio Messina & Co, was the first ever vessel to operate commercially with a scrubber system when it entered service in December 2011. By ‘future-proofing’ the vessel for stringent sulphur regulations, the need to meet the significant price differential for costly distillate fuel when the regulations enter force in 2015, can be avoided. Each ship will feature five open loop scrubbers and will be housed within the ship funnel casings. The equipment also includes a control system, a combined wash-water treatment plant, and a new range of super duplex stainless steel pumps supplied by Wärtsilä Hamworthy’s Singapore plant
