Study Notes

Ship Construction Notes

This module covers ship construction and stability, specifically for nautical science year 3 officers of the watch.
Key ship types are mentioned, including Ro-Ro, crude carriers, kamsarmax, LNG carriers, handysize, reefer, livestock, LPG carriers, heavy-lift, chemical, and coasters.
The module's contents cover various aspects of ship design, construction, and maintenance, including module introduction, exam questions, assignment guidelines, the ship design and building process, definitions and terminology, ship stresses, welding, corrosion, protective coatings, classification, maintenance and survey, ship framing systems, double bottoms, pipes and pumping, bilge systems, ship structures, fore and aft end structure, steering gear, load line rules, hull openings, and sample questions.
The final exam is split between stability and construction (60/40 split) with a 40% pass mark for ordinary degrees and 50% for eligibility for the oral examination.
Learning outcomes include calculations related to IMO Intact Stability for loaded cargo ships, design and construction requirements for specialized ship types, structural arrangements for merchant vessels, watertight integrity and subdivision, and ship building and maintenance processes.
Exam question breakdowns are presented for specialized ship types, merchant vessel structural arrangements, drawings of specific components (duct keel, double bottom structures, etc), and high-stress areas with examples involving bulk carriers, container ships, and tankers.
