Belgain gas shipper Exmar has chosen to go with emissions scrubbers for two of their new 38,000 cubic meter LPG carriers currently under construction at Hanjin’s Subic Shipyard.
Upcoming emissions regulations limit the shipowners’ options to either burning MGO, installing LNG or dual fuel engines, or utilizing scrubbers to curb SOx emissions from burning heavy fuel oil.
Danish OEM Alfa Laval says their PureSOx exhaust gas scrubbers have been chosen for the two ships and will operate in both closed and open loop modes while tied in to a two-stroke Doosan MDT 6S59ME-B 9.3 main engine and three Doosan MAN 8L23/30H Mk2 auxiliary engines.
With a newbuild project such as this, Alfa Laval highlights the necessity to ensure not only accurate delivery times of the equipment to the shipyard, but also close coordination between the OEM and the shipyard with regard to the design of the vessel and how this system will be installed inside.
“The purchase order for a newbuild – unlike that of a retrofit – includes yard-specific demands that must be taken into account,” says René Diks, Manager Marketing & Sales, Exhaust Gas Cleaning at Alfa Laval. “As the scrubber supplier, we must be well prepared to clarify and motivate any technical deviations between our system and the shipyard’s own thinking. This is the basis on which the shipyard makes an informed choice, before the terms and conditions of the contract are even handled.”
Once the scrubber is chosen, a newbuild also places greater emphasis on the speed and accuracy of the supplier’s internal processes, says Diks. “The time constraints are tougher, because the customer and the yard must approve the whole vessel design and not just that of the scrubber,” he explains. “Both parties must accept the technical documents before the project can move forward, and this means we must deliver high-quality documentation within a very short timeframe.”
The two ships will be delivered to Exmar in Q1 and Q2 2016, respectively.
