The environmental regulations for the collection of waste from ships by shore stations are facing difficulties in implementation. One of the reason is the lack of existing port infrastructure. There is a need to look for cost-effective solutions for the construction of an individual port waste collection facility. The other related common reason is the lack of dedicated vessels to handle waste collection, taking into account the numerous and various local conditions which need to be met. Responding to these issues is the proposed design of an innovative waste collection vessel and her dedicated shore station. The innovation of the proposed design outcomes from new functionalities, vessel and shore station modularity’s, zero-emission electric propulsion and readiness to the unmanned operation. From the municipal services point of view an appropriate shore station that is tailored to the ship's service is important. The paper presents continuation of previous works on the shore station, namely the innovative design concept of the connection between the shore station and a port wharf. This presented design is driven by the desire to deploy two functionalities. The first is reduction of wave induced loads acting on the floater. The second is conversion of wave energy into electric power. An important element of the presented work is the evaluation of hydrodynamic loads and the response of the floater to the prescribed wave action. The significant potential of using CFD simulations on a very early design stage is demonstrated, supporting the simulation driven design approach.
