Hamworthy Krystallon scrubber system for Solvang gas tankers

Hamworthy Krystallon reports that it has agreed a significant contract with Hyundai Heavy Industries (HHI) to supply a scrubber system on an 84,000m3 Liquified Petroleum Gas tanker being constructed for Solvang.

This will be, according to Hamworthy Krystallon, the worldʼs first commercially-contracted full vessel scrubber system, comprising two scrubbers; one for the main engine and one combined scrubber for three auxiliary engines. The scrubbers and washwater treatment plant will be of modular design, and situated in the funnel, which the company says demonstrates the applicability of the seawater scrubber concept to helping other vessels comply with upcoming ECA regulations, irrespective of vessel type and size, while burning normal HFO.

The newbuild vessel has been designed for energy efficiency and environmental performance, and among other energy efficiency measures it will be fitted with a new-generation Hamworthy cargo handling system.

Initiatives specific to the exhaust gas cleaning systems, will include varying the washwater amounts depending on the load and sulphur content of the fuel oil, as well as installing an additional particulate matter (PM) capture system, expected to reduce PM emissions by more than 90%.

Hamworthy reminds owners of the 2015 deadline for meeting 0.1% sulphur levels in the European and North American ECAs. The company says that the increased need for speedy decision-making as ship owners and operators face the pressures of meeting 2015 comes as shipowners face-up to the significant costs of using distillate fuel, and the technical challenges of switching from HFO to low sulphur distillate products. With considerable development still needing to be conducted with LNG, the company claims that scrubbing technology remains the only proven and viable solution.

Commenting on the contract, Sigurd Jenssen, managing director, HamworthyKrystallon, said: “We are delighted to be working with Solvang ASA and Hyundai Heavy Industries to deliver the worldʼs first complete scrubber system, and the first ever scrubber to be fitted on a LPG carrier. There is real concern over the 2015 ECA regulations, and we are starting to see more owners and operators actively consider what solution they will employ to remain compliant, but time is running out. Ship owners and operators are increasingly aware of the impending supply chain issue facing the market, but many fail to consider that once a scrubber system is installed, it is important to develop operational experience prior to using on a daily basis.”
