Hva lærer du

The course will provide the necessary knowledge within naval and marine engineering to serve, maintain and supervise on vessels in the role of Naval Engineer and 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 data and coefficients, curve sheets / hydrostatic tables, Bonjean curves, load line marks, submarine hydrostatics, stability, trim and equilibrium polygons.

Intact and damaged stability, 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. Naval rules and requirements for intact and damaged stability. Damage control. Rules and regulations 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 of rudder and propeller. Engine and propeller dimensioning for a given ship. Clutches and couplings. Propeller/rudder shafts and mechanical issues. 

Seakeeping: The vessel's movements in heavy seas. Encounter frequency, response amplitude operator (RAO) and motion spectra. Assessment of seakeeping 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.
