STABILITY ASSESSMENT OF HATCHCOVERLESS RIVER-SEA CARGO SHIP
Tahun 2019
Hatchcoverless General Cargo ships is designed to carry exposed cargo while operating due to certain reason. IMO was
disseminated the Interim Guidelines for Open-Top Containership by IMO MSC/Circular. 608/rev.1 provided a set of
requirement for the design of Open-top Containership. In these Interim guidelines one of the requirement set is related to
the stability of the ship in all conditions, intact and damage. Furthermore, in general, the application of these interim
guidelines is intended for this type of ship that operate in unrestricted service navigation. The Hatchcoverless General
Cargo ship have the same typical design with Open-top Containership, while one or more of the cargo holds need not be
fitted with hatch covers. Since, the intended application is generally for unrestricted service navigation, it becomes
questionable if applied in restricted service navigation, e.g. river sea service navigation. This work will assess the
Hatchcoverless General Cargo ship that has river sea service navigation. This study is working on stability analysis of
this chosen type of ship. A sample model was tested by numerical method in intact and damage condition. Dynamic roll
response was captured to check allowable downflooding point. The result confirmed and compared with the references
regulation. The results found that the model fullfilled criteria in Intact condition, but for flooded cargo hold condition
showed an inapropiate result. Furthermore, assessment for this type of ship should be reviews against the damage case.
