Technicians will often be asked these tasks:

• Providing documentation, detailed instructions, drawings, or specifications to tell others about how devices, parts, equipment, or structures are to be fabricated, constructed, assembled, modified, maintained, or used.
• Using computers and computer systems (including hardware and software) to program, write software, set up functions, enter data, or process information.
• Servicing, repairing, calibrating, regulating, fine-tuning, or testing machines, devices, and equipment that operate primarily on the basis of electrical or electronic (not mechanical) principles.

Analyzers will often perform the following tasks:

• Identifying the underlying principles, reasons, or facts of information by breaking down information or data into separate parts.
• Using relevant information and individual judgment to determine whether events or processes comply with laws, regulations, or standards.
• Assessing the value, importance, or quality of things or people.
• Compiling, coding, categorizing, calculating, tabulating, auditing, or verifying information or data.

• Conducting stability analyses of ships.
• Designing all the hull and superstructure according to specifications and testing data, in conformity with standards of safety, efficiency, and economy.
• Designing layout of craft interior, including cargo space, passenger compartments, ladder wells, and elevators.
• Studying design proposals and specifications to establishing basic characteristics of craft, such as size, weight, speed, propulsion, displacement, and draft.
• Conferring with marine engineering personnel to establishing arrangement of boiler room equipment and propulsion machinery, heating and ventilating systems, refrigeration equipment, piping, and other functional equipment.
• Evaluating performance of craft during dock and sea trials for determining design changes and conformance with national and international standards.
• Overseeing the construction and testing of prototypes in model basin and developing sectional and waterline curves of hull, for establishing the center of gravity, ideal hull shapes, and buoyancy and stability data.
