300,000-dwt Double-Hull Oil Tanker RAMLAH
The 300,300-dwt type oil tanker, RAMLAH, built at the Nagasaki Shipyard & Machinery Works of Mitsubishi Heavy Industries, Ltd. (MHI) was delivered on January 1, 1996, to The National Shipping Company of Saudi Arabia (NSCSA).
RAMLAH is the first ship of five (5) sister ships which were ordered by NSCSA and a new type energy saving high grade double hull VLCC taking into consideration of marine environmental protection and compliance with MARPOL Annex I, Regulation 13F.
A new hull form, small bluntness of fore part and small vessel's breadth 56 m are adopted and achieves lower sea margin in the actual rough sea. The cargo space is divided into five (5) pairs of cargo oil center tanks, five (5) pairs of cargo oil inner side tanks and one (1) pair of slop tanks, and protected by water ballast tanks consisting of double bottoms and double sides. Height of double bottom (3.0m) and width of wing space (3.56m) comply with the new MARPOL requirement (Reg. 13F), furthermore fuel oil tanks are surrounded by double hulls, which is not rule requirement, taking into consideration of marine environmental protection.
The detail structural analysis (Structural Design Assessment, Fatigue Design Assessment) and building controls (Construction Monitoring) are carried out and assigned LRS notation "SHIP RIGHT".
Also Hull Stress Monitoring System (LRS notation "SEA") is adopted and utilized for watching and comprehending of hull stress state.
The ship permits one man bridge operation (LNC(AA)) with functionally arranged wheelhouse and equipment, and with good visibility.
The advanced cargo handling and planning system which is called "SUPER CARGO" supporting a one-man cargo operation, presents the simultaneous conveniences of safety, integrated monitoring and control throughout the whole loading/discharging operation cycle by means of the latest technologies.
The machinery predictive diagnosis/maintenance support system which is called "SUPER PLANT" using artificial intelligence and sophisticated data acquisition techniques, detects any early difficulties of such essential machinery as the main engine, generator engine, etc. in the engine room and prevents serious problems, and the heavy burden imposed on shorthanded skilled engineers is reduced by integrating the conditions of planned maintenance.
The highly advanced navigation system (Integrated Navigation System) also supports integrated bridge operations such as route planning, maneuvering for collision and grounding avoidance and navigation monitoring.
