FAQs
Q1: What is the core unloading advantage of this 2600m³ self-propelled open-hull mud barge?
A1: The barge adopts an integral split-hull design, with the mud tank bottom and bulkhead rotating around deck hinges and separating to both sides under the action of hydraulic cylinders. The cargo in the tank is unloaded by gravity from the bottom, which makes heavy clay and stone easy to discharge. Compared with other mud door unloading methods, it has faster unloading speed and is especially suitable for shallow water unloading operations. It can also be unloaded by mechanical equipment such as grabs.
Q2: What are the main compliance standards and inspection requirements of this mud barge?
A2: The barge fully complies with the 2020 Technical Rules for Statutory Inspection of Domestic Navigation Sea Vessels of the People's Republic of China and its 2022 amendment notices, as well as the 2022 Construction Standards and Material & Welding Specifications of China Classification Society. It has obtained the Certificate of Safety and Environmental Protection for Domestic Ocean-going Vessels, valid until January 22, 2029, and the next annual inspection shall be carried out within three months before and after January 22, 2025. All main equipment is equipped with ship inspection certificates and meets relevant emission and environmental protection requirements.
Q3: What supporting power and electrical equipment is the barge equipped with to ensure continuous operation?
A3: The barge is equipped with 2 sets of main diesel generator sets (model CCFJ75J) and 1 set of mooring generator sets (model CCFJ50J) from Weichai Power, matching Lanzhou Electric Motor Factory marine brushless AC generators; 1 set of shaft-driven generator (30kW, 400V/50Hz) for auxiliary power supply; 2 sets of air compressor units and multiple air bottles for main engine starting,
Miscellaneous use and control; complete backup pump systems for lubricating oil, cooling water, fuel and ballast to ensure the continuous and stable operation of the main engine and hull systems in coastal dredging operations.
