Shipfitting and Steel Fabrication Program Course Descriptions

Shipfitting Fundamentals

The Fundamentals course contains several related topics and is designed to provide the essential foundation for the following courses. Students begin by reviewing expected standard for work ethics as well as techniques for presenting and maintaining a positive and professional image. They then learn the overall operation of a typical ship yard and the types of career professionals that work in the yard.

Ship terminology, Ship Fitter tools, equipment and processes are all related and are basic to performing tasks and building their knowledge in other courses. Students begin to learn the language of ship building which provides a means for important and accurate communications. Also, students learn the names, function, and operation of Ship Fitter related tools and power equipment. In addition, they learn to apply these tools to specific processes that result in desired outcomes.

Various methods of cutting, heating, and burning are applied to hand held torches and processes as well as automated cutting, heating, and beveling processes. Safe operation procedures are emphasized as students learn to cut and shape steel plate and pipe. Next they will learn the types and techniques for using rigging equipment to place prefabricated structure components of the ship.

Applied Math and Measurement

Students enter post-secondary schools with a wide range of math skills. Understanding the application of mathematics functions to ship building is critical to laying out, cutting, and shaping steel structural components of the ships frame, hull, and superstructure. A review of basic math functions to add, subtract, multiply, and divide whole numbers and fractions will be provided. With this understanding students will advance to basic algebraic functions to determine unknown numerical values. They will also learn basic geometric shapes and how to calculate and measure various angles. Basic trigonometric functions are used to calculate triangle angles.

Students will learn to identify and correctly use various types of measuring devices to correctly identify measurements to the nearest sixteenth of an inch in the English Standard measurement system or 1 millimeter in the Metric system. Students will learn to differentiate between these two measurement systems and methods for converting from one system to the other.

To facilitate and reinforce a review of both, basic math and technical math functions, students will apply these skills to basic fabrication techniques. Students will use their math skills to measure distances and calculate angles in learning basic structural fabrication.

Ship Fabrication Drawings

Structural drawings are a way of communicating to the Ship Fitter how the frame, hull, and superstructure are to be constructed. Working structural drawings are primarily two dimensional representations of the ship with dimensions and technical specifications that the Ship Fitter must know in order to properly fabricate the ships components.

In this course, students will first learn the standard drawing practices used to construct drawings. Such drawing conventions as layout, line designation, title block information, dimensions, and specifications will be reviewed. With this knowledge as a foundation, students will first apply their knowledge to specific symbols which identify welding procedures to be used. They will be shown how to translate symbols into specific welding tasks.

Students will then learn how and why ship frames, hull, and superstructures are designed as they are and the dynamics of stresses on the hull caused by oceanic conditions. Building on the language of the Ship Fitter, they will learn about ship stability, buoyancy, stabilizers, as well as decks, holds, and compartments. Students will review actual ship structural drawings to learn about the type of information that is provided on these drawings.

Students will also be introduced to “Lean Thinking” and the ISO 9001 management system. In the process they will better understand the difference between value added and non-value added activities. They will learn about fundamental time and production “wastes”, how to manage them, and methods for improving the work area.

A field visit to a working ship yard will reinforce with students the basic concepts, skills, and knowledge they have learned but provide a connection between the classroom and the ship yard.

Shipfitting Welding

Once Ship Fitters have placed steel framing or sheet steel into place, they apply critical tack welding procedures to hold the pieces in place prior to finish welding. To do so, Ship Fitters need to understand and correctly apply SMAW or FCAW welding techniques, depending on the application. Students learn to tack weld steel components to correct standards so the marine welder can complete the weld with no additional preparation. This process ensures the pieces have been correctly placed and allows the welder to weld at production rates.

This course introduces students to Shielded Metal Arc Welding (SMAW) and Flux Core Arc Welding (FCAW) processes used to weld steel plate and pipe. Students first learn about welding equipment, settings, setup, and electrodes. Once students develop control of the electrode to the base metal, they will apply this technique to flat, vertical, and overhead positions. Using both processes, students will learn to apply the proper technique for tack welding steel components to meet code standards.

Shipfitting II

This course is designed to take the student to a more advanced level of ship fitting and fabrication. Students will apply all of the skills and knowledge previously learned to specific fabrication and fitting tasks. To introduce this course, students learn the various common shapes of structural steel, the characteristics of each, and how they are generally applied to construct structures.

Students then learn the purpose or function of specific ship fitting aids, how to fabricate each, and how to apply them effectively. Once the use of each fitter aid is understood, students learn to apply specific alignment and fit-up techniques. In the process they learn to operate and apply various types of lifting and power hydraulic equipment to lift, align, fit, pre-heat, and tack weld a ship’s structural components. Once these operations are complete, students learn what to look for to inspect prior to final welding operations.

Because aluminum has become popular in constructing a ships superstructure, students will spend the remainder of the course time learning to apply GTAW techniques to welding aluminum. They will learn to apply this process in the flat, vertical, and overhead positions.

Shipfitting Practicum

This course is designed to allow students to apply all they have learned to a real or simulated ship fitting and fabrication experience. It reinforces all they have learned and provides an opportunity to increase production rates. Students will either fabricate or repair hull, frame, or bulkhead components on a ship simulator. It will require correctly reading and interpreting drawings, laying out and fabricating ship components, properly aligning and fitting up components, and tack welding all components in place. Instructors will supervise to ensure all safety procedures are followed and serve as advisors, but most of the activities will be implemented by students. At the conclusion of the exercise, students and instructors will inspect and evaluate the finished “product”.
