Marine Structures Laboratory

Published 27 November 2014

The main activities in the laboratory are the testing of structures, structural components and materials. Typical problems involve fatigue testing, ultimate strength and collapse testing. Experimental work is often combined with analytical or numerical analysis.

Small scale testing can be performed to obtain material data and material coefficients to be used in numerical analysis and full scale testing. Dynamic full scale testing is performed for qualification of flexible risers, power cables, umbilicals, hoses and mooring lines. A wide range of structural analysis programs are available for linear and non-linear static and dynamic analyses. These include special programs for fatigue and fracture mechanics analysis, and the collapse behaviour of intact and damaged structures.


Main installations

Actuators: A range of servohydraulic actuators for static and dynamic testing, from 100 kN load capacity to a maximum load/stroke of 4000 kN/1000 mm.

Control system: Several computerized systems for multi-actuator control, fatigue load simulation, data logging with on-line reduction and analysis.

Small scale testing:

Modular frame system which can be built to accomodate specimens and structural models with a wide range of shapes and sizes, under unaxial or
multiaxial loading, and with load capacities up to 4000 kN.


Full scale testing:

Dynamic test rigs for static, dynamic and fatigue testing of slender marine structures. The dimension of the test specimen are typically15m flange to
flange, and applied loads include internal pressure, dynamic bending (±30°) and tension (3000 kN).
Experimental work is often combined with analytical or numerical analysis. A wide range of structural analysis programs are available for linear and non-linear static and dynamic analyses. These include special programs for fatigue and fracture mechanics analysis, and the collapse behaviour of intact and damaged structures.
The Marine Structures Laboratory is operated by MARINTEK, Dept. of Structural Engineering, in cooperation with Norwegian University of Science and Technology, Dept. of Marine Structures.
