Abstract	Accidents by trawling impact have the potential of environmental consequences, in terms of safety, monetary values and reputation. Aware of this situation a technology development plan on “Pipeline subject to high interference loads” has been established at STATOIL in close collaboration with GASSCO. The overall achievement is to adapt and introduce more reliable assessment methods in the load and response of pipelines under a trawling impact scenario. This work includes a review of some known force-indentation models appeared in the literature. Some comments on the recently updated version of the DNV-RP-F111 document. Next, the description of the numerical results of 12 analyses of steel pipes studied is described and based on these results a new force-dent proposal is presented. The proposed equations are validated against experimental tests and the findings indicated fairly good predictions as indicated in the conclusions.
