Maintenance of twin X-DF engines was accomplished by group from CMS Korea
In a procedure including an LNG vessel secured in the Sabine Pass, Texas, CSSC Marine Service Co (CMS) has actually finished the very first significant overhaul on 2 Winterthur Gas & & Diesel (WinGD) X-DF engines in just 9 days.
CSSC Marine Service Co (CMS) is the tools solution subsidiary of China State Shipbuilding Corp (CSSC), which possesses WinGD.
The twin 6X62DF engines revamped by CMS are those in the initial X-DF powered vessel to go into procedure, the 2017-built 180,000-cu. m, Panama- flagged LNG vessel, SK Audace, which is had as well as run by South Korea’s SK Shipping.
In the 3 years given that vessel distribution, the X-DF engines set up in SK Audace had actually gotten to 18,000 running hrs, greater than 99% of which remained in gas procedure as well as much less than 1% in diesel procedure, needed for handling. Therefore, arranged upkeep was called for to guarantee constant undisturbed procedure.
A group from CMS Korea finished the complete upkeep of both engines within 9 days, as well as the ship went back to business solution after an effective sea dry run. This was completed in spite of the restrictions on traveling, logistics, health and wellness, as well as security functioning strategies brought on by COVID-19 constraints.
Although job ranges were differed, CMS as well as WinGD teamed up to implement the task according to the conventional guidebook for the engine kind. Original extra components such as piston rings as well as gas elements were supplied to the vessel’s place by CMS.
During the overhauls, no irregularities were discovered. Although the CMS Korea group was the very first to execute upkeep on X-DF innovation, it prepared job standards well that included the booking of appropriate products as well as real-time assistance from the WinGD style group.
The CMS Korea group reported that the 6X62DF engine components remained in extremely great problem contrasted to engines traditionally revamped by CMS that operate hefty gas oil (HFO).
Following the overhaul, the dry run of the engines was carried out as well as enhanced engine efficiency was adjusted. To guarantee optimum engine operating criteria with to the following routine upkeep, the CMS Korea group carried out upkeep on usual elements such as pistons, exhaust shutoffs, circulation restricting shutoff were revamped as well as gas pump element substitutes were made where needed. Additionally, the overhaul consisted of a lot more intricate gas elements such as gas admission shutoffs (GAV), pre-chamber substitutes as well as gas shutoff devices (GVU).
In total amount, 10 X-DF engines in 5 vessels will certainly be revamped by CSSC Marine Service in the coming months. Results of the continuous condition-based examination on all 5 vessels will certainly allow boosted TBO (time in between overhaul) or CBM (Condition based Maintenance) choices, to be concurred in between the shipowner as well as category culture.
“For customers who operate X-DF engines and have concerns about service accessibility, CMS is able to provide qualified service through our growing network,” states Andrew Stump, President CMS. “This is the initial X-DF significant engine overhaul finished as well as our group supplied such a brief turn-around time for a twin-engine setup. that genuinely shows what is feasible. As the need for our solutions expands, CMS will certainly proceed its development right into even more areas worldwide.
“The results recorded in the service reports have been investigated together with WinGD Product Managers in the Swiss headquarters, and we are all extremely happy with the condition and cleanliness of engine components, in particular compared to an engine of the same running hours operating on HFO. The results of investigation by WinGD will enable any design optimization necessary and extension of the time between overhauls where appropriate. Once we have comparative results from the sister vessels we will be able to confirm the success of the X-DF product as the most reliable and sustainable LNG main engine solution”
To- day, CMS has actually developed 3 solution centers situated in South Korea, Singapore as well asHamburg In enhancement to the solution centers as well as runs 5 gas station situated in China (Qingdao, Gaungzhou, Chengxi as well as Shanghai), South Korea, Singapore, Hamburg as well asSwitzerland Partner gas station are likewise found in nations consisting of Brazil, Turkey, Poland, South Africa, Oman, Qatar, Dubai, UNITED STATE, New Zealand as well as Greece.
