The paper deals with the topic of monitoring the performances of a vessel in service in order to establish whether fouling of the hull have worsened the hydrodynamic efficiency of the ship. In the paper the aspects of acquisition, treatment and presentation of the data are discussed. Particular focu...

A vessel traveling across the sea experiences waves. The waves produce forces on the vessel resulting in added resistance. The forces are caused by the combination of wave and vessel motion. A variety of methods for prediction of added resistance in waves exists. The complexity and accuracy varies s...

This paper describes an experimental and numerical study on the effect of bilge keels on a specific offshore vessel. Forced roll and free decay experiments were carried out at MARINTEK in a joint project between VARD, DNV GL and MARINTEK during Nov. 2012. The 1:25 ship model was tested both with and...

The positioning capability is a crucial property for safe and reliable operations of a dynamically positioned (DP) offshore vessel. The limiting factor in such is the vessel's thruster configuration and the maximum resultant forces and turning moment this can produce in all directions. Based on the ...

The pristine Arctic region is vulnerable and the robustness of Arctic ecosystems is not fully known. Bearing in mind serious accidents in oil and gas production in other parts of the world, it is important to develop methods, equipment, procedures and human competences that will make oil and gas exp...
