An Overview of New Coastal Research Vessel (N-CRV) Dry Dock and Construction
Abstract: A New Coastal Research Vessel (N-CRV) is a specialized ship designed for scientific research in fields like oceanography, geology, biology, and atmospheric studies, equipped with specific facilities and accommodations for sea missions. This paper discusses the coastal research ship dry-dock, construction, and design process, which involves three stages: concept, preliminary, and contract design. N-CRV must utilize scientific cruise, Exclusive Economic Zone (EEZ) survey, deployment, data collection, and seawater sample collection …

Concept Design of a Simple Marine Dry Dock (Without Gate)
Abstract: This article explores various options for facilities used in underwater ship repair, including Dry Dock, Ship Lift systems, Floating Dry Docks, and Simple Slipway systems with cradle and winch. Such facilities are crucial to any ship repair operation. Among these, Dry Docks are known for their high capital cost and limited capacity to repair only one ship at a time. This makes them less appealing unless there is substantial demand …

Accuracy Improvement for Propeller Cavitation Noise Prediction Using UDF
Abstract: Recently, there has been an increase in demand for propulsion systems with higher hydrodynamic performance and lower underwater-radiated noise, as environmental issues are gaining more attention in addition to the traditional military necessity. It is important to reduce cavitation noise when designing propellers of the ships, especially for oceanographic research vessels because they use acoustic instruments and cavitation noise can interfere with their operation. It is well known that, when …
