### Possibilities of Implementing the IMO Resolution Guidelines A.1158(32)  
When considering the possibilities of implementing the IMO resolution [13], the basic differences between the two documents [1] and [13] should be indicated. Resolution [1] was implemented in 1997; all three described VTS systems have been adopted and applied the requirements contained in this document from the beginning of their existence and a work organization based on three defined services was implemented (see Section 1). The new resolution [13] entered into force on 15 December 2021; none of the Polish VTS systems have implemented it so far. The new resolution [13] in its provisions moves away from defining services in favor of actions and the need to develop scenarios of the occurrence of various situations that may pose a threat to ships, navigation and the natural environment. The new resolution does not define services but specifies a set of activities that should be taken to mitigate the development of dangerous situations [13]. The above-mentioned set of intended activities has been divided into three groups, each with its own purpose, as follows [13]:  
1. Providing timely and relevant information on factors that may influence ship movements and assist onboard decision-making;
2. Monitoring and managing ship traffic to ensure the safety and efficiency of ship movements;
3. Responding to developing unsafe situations. An assessment of the IMO Resolution Guidelines A.1158(32)'s current implementation by the analyzed VTS systems is presented in Table 9. The purposes (activities) assigned to the specific groups identified in Resolution [13] were evaluated. The authors assessed the particular activities performed by the VTS systems operating in Poland using the following measurements:  
* YES--the activity is performed,
* NO--the activity is not performed,
* IN PART--the activity is performed in part. Based on the results of assessment presented in Table 9, it can be concluded that the implementation of Resolution [13] for the three VTS systems should be as follows: \begin{table}

* The assessment took into account the integration of road/rail and maritime transport modes with European inland navigation. ** Indirect impact of VTS Lavika Shupska on the TEN-T has been assessed, considering that the area managed by this system is not located within TEN-T transport corridors network.

Table 8: _Cont._* In the case of the VTS Zatoka Gdanska system, it should not be difficult. The implementation of new rules will require formal changes and provisions in internal documents and operational procedures.
