Comparison of methods is on Blackboard

Materials on Blackboard1. Todays powerpoint slides 2. Comparison of launching and retrieval types important reading and understanding. 3. Overview of the international commercial shipbuilding industry, EU/First Marine, 2003: Read Section 2 (Key Terminology) before next week. Knowledge of terms is essential for the rest of the course. Good further reading for the shipbuilding sector if wished. 4. Compensated Gross Tonnage system, OECD, 2007: reference work for use during the course.
