Construction

Design Basis
MSA 2020 Statutory Inspection Rules for Vessels and Marine Facilities Statutory Inspection Technical Rules for Domestic Navigable Seagoing Vessels 2018 CCS Code for Construction of Domestic Navigable Seagoing Vessels 2019, 2019 Notification of Modification 2020 CCS Material and Welding Code 2018, 2018 and 2020 CCS Notification of Modification

Operation mode
Self-suction: The sand suction pump group sucks the sand pump in the riverbed through the sand suction pipe on the right side of the ship to the sand discharging pipe above the cargo compartment, and then discharges to the compartment through the filter screen.

Self-discharging: The sand in the cargo hold is transported to the front end of the ship through the bilge conveyor belt and transferred to other places. The conveyor belt is driven by the engine room of the ship head conveyor belt.

Changes applied for:
The self-suction self-discharging vessel is converted from the self-discharging vessel.
The caoside wall of the fore peak cabin conveyor belt extends to the bottom of the cabin and is watertight.
Change the water pump tank (right) to sand suction pump tank (right) and change the normal cabin to class A machinery space.
Add a groove to the bottom plate at the collision bulkhead, which is higher than the full load waterline.
Cancel weathertight hatch cover at the exit of cargo hold and first conveyor belt.
The design draft is changed from 4.60m to 3.55m, and the relevant load line draft drawing and relevant drawings are all changed.
