Recently, Suzhou Cosc Marine Machinery provided maintenance services for the large‑size controllable‑pitch propeller of the Changjing No. 6, a large trailing‑suction dredger owned by the Yangtze River Wuhan Waterway Engineering Bureau. Following the overhaul, the product successfully completed sea trials, with its post‑repair performance meeting expected requirements.
The controllable‑pitch propeller onboard the vessel had been in service for six years. Prior to the overhaul, prolonged heavy‑duty dredging operations caused successive equipment failures. To completely resolve the malfunctions, the ship‑owner turned to Suzhou Cosc Marine Machinery for assistance without delay.
Subject to project‑schedule constraints, the ship‑owner required the overhaul to be completed within the shortest possible timeframe, demanding seamless connection among vessel docking, equipment disassembly for workshop repair, on‑site reinstallation and sea trials. Ultimately, Suzhou Cosc Marine Machinery finished the controllable‑pitch propeller overhaul in minimal time, saving substantial time and costs for the ship‑owner and winning high recognition.
Meanwhile, the company delivered post‑marine‑accident overhaul services for controllable‑pitch propellers aboard two official‑service vessels. Suffering marine‑accident damage, the two official‑service vessels sustained severe damage to their controllable‑pitch propellers and shafting systems, rendering them inoperable. The company mobilized senior technical staff to rapidly deliver emergency response solutions and guided the vessels to return safely to port.
Given pending law‑enforcement missions for the official‑service vessels, subsequent overhaul work had to be finished as quickly as possible. Adopting staggered‑shift production arrangements, the company’s production department reserved key large‑scale equipment specifically for the overhaul tasks.
Overhaul services for marine propulsion equipment impose stringent requirements on both turnaround time and repair quality. Backed by a full set of large‑scale processing and inspection equipment, abundant spare‑parts inventory and a professional maintenance team, Nanjing High‑Accuracy Marine Suzhou Cosc Marine Machinery is capable of delivering timely and professional overhaul services for propulsion equipment to ship‑owners.
The successful completion of the above‑mentioned overhaul projects marks an important breakthrough for Suzhou Cosc Marine Machinery in the thruster‑repair sector, enabling it to provide overhaul services for various types of marine propulsion equipment for ship‑owners.
