CSSC Marine Service Co (CMS), the globally devices solution subsidiary of China State Shipbuilding Corp (CSSC), has actually finished the very first significant overhaul on 2 WinGD X-DF engines in just 9 days.
The twin 6X62DF engines upgraded by CMS come from the very first X-DF powered vessel in procedure, 2017-built 180,000-cbm LNG vessel, SK Audace (Owned as well as run by SKShipping Co LTD), which was secured at the Sabine Pass anchorage in Texas.
In the 3 years given that vessel shipment, the X-DF engines set up on SK Audace had actually gotten to 18,000 running hrs, >> 99% of which were gas procedure as well as << 1% Diesel procedure needed for manoeuvring. Therefore, arranged upkeep was needed to guarantee continual undisturbed procedure.
The CMS Korea group finished both engines complete upkeep within 9 days, as well as the ship went back to industrial solution after an effective sea dry run. All this regardless of the traveling, logistics, wellness, as well as security functioning strategies brought on by COVID19.The simpleness of the X-DF engine for upkeep, paired with the ability as well as devotion of the CMS group allowed the rapid overhaul time.
Although job ranges were differed, CMS as well as WinGD teamed up to implement the work according to the conventional handbook for that engine kind. Original extra components such as piston rings as well as gas elements were supplied to the vessel’s area by CMS.
During the overhauls, no irregularities were located. However, the group conquered the difficulty of the unidentified as well as being the very first to execute upkeep on X-DF modern technology. The CMS Korea group prepared their job standards well that included the appointment of right products as well as real-time assistance from the WinGD style group. In doing so, the CMS Korea group addressed all obstacles ran into as well as had the ability to decrease the upkeep time to 9 days. The CMS Korea group additionally observed that the 6X62DF engine components remained in exceptionally excellent problem contrasted to engines traditionally upgraded by CMS that operate hefty gas oil (HFO).
Following the overhaul, the dry run of the engines was done in solution power as well as enhanced engine efficiency was adjusted. To guarantee optimum engine operating criteria with to the following regular upkeep, the CMS Korea group carried out upkeep on usual elements such as pistons, exhaust shutoffs, circulation restricting shutoff were upgraded as well as gas pump part– substitutes where essential. Additionally, the overhaul consisted of a lot more complicated gas elements such as gas admission shutoffs (GAV), pre-chamber substitutes as well as gas shutoff systems (GVU).
In complete, 10 X-DF engines on 5 vessels will certainly be upgraded by CSSC Marine Service in the coming months. Results of the continuous condition-based examination on all 5 vessels will certainly allow raised TBO (time in between overhaul) or CBM (Condition based Maintenance) choices, to be concurred in between the ship proprietor as well as category culture.
Andrew Stump, President CMS states: “For clients that run X-DF engines as well as have issues regarding solution ease of access, CMS has the ability to give competent solution with our expanding network. This is the very first X-DF significant engine overhaul finished as well as our group supplied such a brief turn-around time for a twin-engine installment. that absolutely verifies what is feasible. As the need for our solutions expands, CMS will certainly proceed its development right into even more places 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 optimisation 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”
SK Audace superintendent claimed: “As the first ever X-DF engines, I had concerns about the scope of the project. But the CSSC Marine Service team demonstrated their ability with a fast and professional overhaul. Working closely with WinGD really made a difference to how quickly we were able to resume operations. We look forward to working with the team again in the future.”
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 additionally found in nations consisting of Brazil, Turkey, Poland, South Africa, Oman, Qatar, Dubai, United States, New Zealand as well as Greece.
