Abstrakt: Accidental damage to underwater cables caused by ship traffic seems to be a current problem. According to the statistics more than 44 percent of such damage is caused by fishing vessels. The reason for the next 14 percent is damage from ships’ anchors. The construction of the underwater installation risk model was based on the determination of the density of the traffic in the area where the installation is located. There are several models used to assess the risk of underwater cable damage requiring the implementation of data on the density of traffic of fishing vessels. For this purpose, they usually use AIS (Automatic Identification System) data or statistical data on traffic density in the areas called fishing squares. The aim of this article was to compare traffic data that was based on two independent systems AIS and VMS (Vessel Monitoring System) and verify the reliability of them. The research was carried out in the area of the Slupsk Bank where an underwater cable has been damaged several times. The authors have demonstrated the need to verify the data from both systems in order to obtain reliable information about fishing vessels.

Słowa kluczowe:  offshore industry, offshore risk management, offshore safety, underwater gas pipelines

Abstrakt: The paper discusses issues of the impact of traffic density of the vessels on the sea surface to offshore underwater pipelines. The risk includes vessel foundering, sinking, grounding, dropping and dragging anchors, trawling fishing gear. The density of merchant, offshore field support vessels and fishing vessels presented by this paper is base for build risk model for underwater infrastructures. As an example it has been analyzed ships traffic over underwater gas pipeline between platform Baltic Beta and Wladyslawowo power plant.

Słowa kluczowe:  criteria of accidental damage, damage to the pipeline, Gdansk Bay Area, pipeline, Ships Anchors, subsea gas pipeline, underwater infrastructure, vessel's damage consequences

Abstrakt: This paper discusses issues of the accidental anchor damage to offshore subsea pipeline as one of the most significant threat to underwater infrastructure. The density of vessel traffic over the pipeline between platform Baltic Beta and Wladyslawowo power plant has been analyzed. In order to determine the most common damages associated with heavy ship traffic, the authors used the risk model for underwater infrastructure. For this purpose ships anchor equipment has been categorized and as the results the criteria of damage to the pipeline have been discussed.
