This paper introduces a methodology for predicting a warehouse’s reduced load while offering flexibility. Physics-based energy simulations are first performed to model flexibility events, which involve adjusting cooling setpoints with controlled temperature increases to reduce the cooling load. The...

The Norwegian Coastal Administration registers maritime incidents in Norwegian waters. Drifting ships and drifting objects may cause serious incidents and possible disasters. By analysing ship traffic in Norwegian waters, it is documented that the frequency of drifting ships has been approximately...

Energy retrofit of existing masonry buildings has become attractive to meet demands for reduction in energy consumption. Retrofit may, however, introduce moisture risk that needs to be assessed. Hygrothermal simulation analysis is often conducted in this respect. Nevertheless, hygrothermal...

The main purpose of this study is to investigate the adhesion between corroded aluminium conductor strands and the semi-conductive cable screen. In this paper it is proposed that increased adhesion is one of the pre-requisites for the local degradation of the semi-conductive cable screen...

The use of TR-XLPE for the insulation of a wet design submarine cable has been a widely adopted design, however CIGRE TB 722 requires a long-term ageing test to qualify wet design insulation. Currently very few information is available in the literature regarding the long-term performance...

Testing of high voltage cables according to the recommendations by Cigre TB722 is discussed, based on calculations of water diffusion and measurements of ion migration in an extruded 52 kV XLPE subsea cable. Calculations show that, for this cable design, 1000 h is required to obtain an...

Current tools for ampacity calculations are based on analytical expressions, and empirical expressions for complex laying geometries that in practice cannot be solved analytically, formulated in the IEC standards. Non-standard or highly complex laying geometries must be simplified and...

Power cables in air- or water-filled pipes are the thermal bottleneck in many installations. Some parts of the industry reduce the complexity of their numerical models by combining conduction, convection, and surface-surface radiation into an effective thermal conductivity by formulas and...
