COURSE OVERVIEW:

The Hull and Structural Inspection During Dry Dock course is a technical program focused on the critical assessment of a vessel’s integrity. This course examines the systematic procedures for identifying structural weaknesses, corrosion, and fatigue that are only visible when the ship is out of the water. It provides a detailed framework for performing inspections that satisfy both internal maintenance requirements and the rigorous standards of Classification Societies.

The scope of this training involves the evaluation of all submerged and internal structural components, including the keel, shell plating, framing, and tank internals. Participants will explore the use of Non-Destructive Testing (NDT) methods, such as Ultrasonic Thickness Measurement (UTM) and Magnetic Particle Inspection (MPI), to detect hidden flaws. The program emphasizes the interpretation of "Wear and Tear" vs. "Structural Damage," allowing inspectors to make informed decisions on steel replacement or reinforcement.

Coverage includes the analysis of corrosion patterns—such as pitting and microbial-induced corrosion—and the effectiveness of existing protection systems. The course addresses the documentation of structural surveys, the calculation of "Diminution" levels, and the coordination with Class surveyors for final approval. By combining engineering principles with practical shipyard experience, this course equips technical managers and surveyors with the expertise to ensure the long-term structural safety of the vessel.

COURSE OBJECTIVES:

After completion of this course, the participants will be able to:

1. Conduct a systematic hull survey following a docking event.
2. Identify different types of structural deformation and buckling.
3. Utilize Ultrasonic Thickness Measurement (UTM) for steel gauging.
4. Distinguish between various corrosion profiles (General, Pitting, Galvanic).
5. Interpret structural drawings and "Scantling" requirements for repairs.
6. Evaluate the integrity of welding seams and "Butt" joints.
7. Inspect internal tank structures, including floors, girders, and stringers.
8. Manage the survey of "High Stress" areas prone to fatigue cracking.
9. Verify the effectiveness of cathodic protection and sacrificial anodes.
10. Determine steel replacement quantities based on Class diminution limits.
11. Document structural findings using standardized reporting software.
12. Coordinate "Hot Work" repairs with safety and Class surveyors.
13. Lead the final inspection of the hull before undocking.

TARGET AUDIENCE:  

Technical Superintendents, Marine Surveyors, Shipyard Hull Managers, Integrity Engineers, and Chief Officers.

TRAINING COURSE METHODOLOGY:

A highly interactive combination of lectures, discussion sessions, and case studies will be employed to maximise the transfer of information, knowledge, and experience. The course will be intensive, practical, and highly interactive. The sessions will start by raising the most relevant questions and motivating everybody to find the right answers. The attendants will also be encouraged to raise more of their questions and to share in developing the right answers using their analysis and experience. There will also be some indoor experiential activities to enhance the learning experience. Course material will be provided in PowerPoint, with necessary animations, learning videos, and general discussions.

The course participants shall be evaluated before, during, and at the end of the course.

COURSE CERTIFICATE:

National Consultant Centre for Training LLC (NCC) will issue an Attendance Certificate to all participants completing a minimum of 80% of the total attendance time requirement.
