Largest hybrid scrubber installed at Chengxi shipyard

Even in the current, difficult times, ANDRITZ has succeeded in delivering a scrubber right on time to Chengxi shipyard for the Dole Food Company. The multi-inlet hybrid scrubber supplied was the largest ever installed at Chengxi shipyard, with an outer diameter of 4.1 m and an overall footprint of around 7.1 x 4.1 meters on board the MV Dole Maya.

ANDRITZ SeaSOx technology  – exhaust gas cleaning systems for the marine industry

Vessel particulars:

Length, overall: 195.00 m

Breadth (mld): 32.20 m

Depth (mld): 17.00 m

Scantling draught (mld): 11.50 m

The Dole Maya is a Reefer Container ship and currently sails under the flag of the Bahamas.

Additionally, ANDRITZ AG was responsible for environmental compliance certification under the supervision of the DNV GL classification society. After the successful sea trial, the necessary IAPP certificate was issued. The ANDRITZ AG SeaSOx system will treat the exhaust gas from one main engine and four auxiliary engines to fulfill the MARPOL requirements.

ANDRITZ will also supply a hybrid scrubber for the Dole Maya’s sister vessel, Dole Aztec, which will be completed and delivered to the Dole Food Company in April 2021.

The Dole Maya scrubber project was the result of international collaboration within the ANDRITZ GROUP, as the equipment was engineered and designed in Austria and manufactured at the company’s own production facility in China. Project management was handled by an experienced Croatian colleague from the maritime industry.

With this installation, ANDRITZ is proud to be the only company globally to offer, deliver, install and successfully commission the complete portfolio of exhaust gas cleaning systems for maritime vessels. The portfolio includes open-loop and hybrid scrubbers as inline (I-type) and bypass (U-type) models for wet scrubbers as well as the dry, Dual Filtration system without any wash water. In addition, ANDRITZ now also has experience with various major classification societies, such as DNV GL, ABS and RINA.

To extend its portfolio, ANDRITZ is now developing a barge solution – SeaSOx Barge – for vessels on stay in port that will reduce the level of SOx, NOx and ultrafine particulates in the exhaust gas regardless of the size of the vessel or its engines.
