ZHENIT concept is based on a combination of different innovative technologies able to convert waste heat available on-board into electricity, heating, cooling, desalinated water and mechanical energy.

This can be considered the most complete configuration that can be adapted to a large variety of vessels. • La Naumon-like system: including the ORC, the TES and the ADS (only providing cooling). This system is considered relevant whenever the mission profile of a vessel comprises short to medium sailing phases followed by short to medium docking phases in the harbour. • Olympic Champions-like system: including ORC and IS. This system is considered relevant whenever the mission profile of a vessel comprises shor sailing phases followed by brief docking phases, e.g. embarking/disembarking passengers like for a ferry. • Cruise ships-like system: this is conceived in two different architectures, in both cases ORC and TES are integrated, while in one case the ADS is integrated while in the other one the IE. The selection of the most proper one will then depend on the most efficient one depending on the achievable savings, space availability and other technical aspects. An example of P&ID realized, for the generic system, is represented in the deliverable.

Specifically, for each system, the possible services to the vessel (e.g. power, heating, cooling generation) were listed and the possible operating modes that can be activated to cope with these requests were defined.

Abstract
ZHENIT concept is based on a combination of different innovative technologies able to convert waste heat available on-board into electricity, heating, cooling, desalinated water and mechanical energy. During the Task 3.1 activities, summarized in the present deliverable, different possible layout configurations were derived for some example of possible reference vessels. Specifically, the following ZHENIT architectures were defined: • Generic system: including all the ZHENIT technologies, namely, Organic Rankine Cycel (ORC) with ejector-aided heat pump, thermal energy storage (TES), adsorption cooling and desalination machine (ADS) and isobaric engine (IE). This can be considered the most complete configuration that can be adapted to a large variety of vessels. • La Naumon-like system: including the ORC, the TES and the ADS (only providing cooling). This system is considered relevant whenever the mission profile of a vessel comprises short to medium sailing phases followed by short to medium docking phases in the harbour. • Olympic Champions-like system: including ORC and IS. This system is considered relevant whenever the mission profile of a vessel comprises shor sailing phases followed by brief docking phases, e.g. embarking/disembarking passengers like for a ferry. • Cruise ships-like system: this is conceived in two different architectures, in both cases ORC and TES are integrated, while in one case the ADS is integrated while in the other one the IE. The selection of the most proper one will then depend on the most efficient one depending on the achievable savings, space availability and other technical aspects. An example of P&ID realized, for the generic system, is represented in the deliverable. It reports all the sensors and actuators needed to properly monitor and control the operation of the ZHENIT system onboard. The full list of sensors and actuators was extracted and organized as input and outputs. According to the information shared by each technology developer, the specific operating modes of each ZHENIT technology were defined as basis to identify the possible operating modes of the overall ZHENIT systems. Specifically, for each system, the possible services to the vessel (e.g. power, heating, cooling generation) were listed and the possible operating modes that can be activated to cope with these requests were defined.
