Course content

The course will provide the necessary knowledge within marine technology to serve, maintain and supervise on vessels in the role of marine engineer and sea damage control officer in the Navy. It will form a good academic basis for the bachelor's thesis and further studies.

The course has the following academic content: 

The ship's geometry and hydrostatics: Presentation of lines plans, calculation of hydrostatic sizes and coefficients, curve sheets / hydrostatic tables, Bonjean curves, load line marks, submarine hydrostatics, stability, trim and equilibrium polygons.

 Stability when intact and damaged, surface vessels: Transverse and longitudinal stability. Loading, unloading, determination of light ship displacement, weight calculations, free surface effect and damage at sea, stability when docking/ running aground, presentation of GZ curves from lines plans, dynamic stability. Military requirements for stability when intact and damaged. Sea damage control. Rules for warships. The Norwegian Maritime Directorate's and classification societies' regulations for merchant vessels. Relevant IMO Conventions (SOLAS, MARPOL and Load Lines). 

Strength, structure and hull maintenance: Construction of hull structures, the lines drawing basis for hull construction. Choice of materials, global and local loads on the hull. Loads on the hull girder in calm seas and for special designs. Shear force, torque and deflection diagrams, stress analysis of the cross section midships, buckling of columns and plate fields, shock loads and ship's response, periodic inspection and maintenance of the hull, rules/standards for the construction of war vessels, Norwegian Maritime Directorate's and classification societies' regulations for merchant vessels, vessel classification. International regulations, IMO and SOLAS. 

Resistance and propulsion: Resistance components. Methods for calculating towing resistance and towing power. Model testing in towing tank with accompanying full-scale test data. Propeller and water jet theory. Determination of a propeller's main dimensions, propulsion efficiency, cavitation problems, including propulsion and hull noise. Cavitation tunnel testing. Engine and propeller dimensioning for a given ship. Clutches and couplings, dimensioning of swage and shrinkage couplings. Propeller/rudder shafts and fatigue 

Seagoing properties: The vessel's movements in heavy seas. Encounter frequency, response amplitude operator (RAO) and motion spectra. Assessment of seagoing properties. Model testing. Roll damping, performance of various installations, demonstration of roll damping. 

Manoeuvring properties: Rudders and fins. Hull and rudder design in relation to manoeuvrability, fin model testing. Manoeuvring tests and NATO requirements. Shallow water effects, simulator and model testing. 

Design: Design of vessels - up to construction contract. Life cycle considerations, shipbuilding methods, workflow on construction site from contract to delivery. 

Naval military vessel concepts: Vessel types relevant to the Navy and the theory behind these.

The course follows the STCW code tables: A-III/1, A-III/2 and STCW function: Marine engineering, controlling the operation of the ship and care for persons on board at the operational and management levels.

Learning outcome


After completing the course, the cadet is able to:

  • explain military and civilian vessel designs regarding stability, sea damage control, strength, a ship's power requirements and dynamic properties, maintenance and supervision
  • explain the energy conversion to the propulsion line and the interaction between ships and their propulsion systems
  • relate relevant military/civilian regulations in the field


After completing the course, the cadet is able to:

  • reason systematically and solve problems related to a naval vessels' stability, conditions in relation to strength, movements and the energy demand for propulsion
  • apply and explain the efficiency of propulsion lines for various vessel solutions
  • determine the dimensions of a divided propulsion shaft with associated swage and shrinkage coupling with respect to load and fatigue issues
  • use laboratory facilities and measuring equipment, as well as produce and interpret measurement data
  • use relevant computer tools to analyse basic and more advanced conditions

General competences

After completing the course, the cadet is able to:

  • communicate with others about vessels and vessel propulsion both verbally, in writing and with a system of formulas
  • explain how new knowledge and methods in the field are developed, and what significance this has for the engineering practice
Working and learning activities

Emphasis is placed on using examples from service to illustrate topics in the course.

  • Curriculum review using questions/discussions (approx. 90 hours)
  • Calculation exercises and exercise review by student/teacher
  • Student presentations, compulsory assignments, tutorials and independent study (approx. 88 hours)
  • Laboratory exercises and computer simulations (approx. 25 hours)
  • Tests

The course is coordinated with workshop practical training/periodic voyages and the courses Marine Propulsion Machinery, Marine Turbine Engines, Engine Construction and the Science of Engineering and Building Materials as well as Marine Machinery Systems and Survivability.

Sensor system

Examination is carried out according to the Regulations for Admission, Studies and Examinations (in Norwegian, “Forskrift om opptak, studier og eksamen”) at the Norwegian Defence University College.
