Boating field trips must comply with the requirements of maritime legislation. Personnel in charge of boats are responsible for ensuring they have the appropriate licences and any appropriate boat registrations are obtained. Boats should be well-maintained and equipped with adequate spare parts and tools, according to the area worked and the length of the trip. Care must be taken when loading boats. The maximum capacity that the boat can carry must be displayed on the boat and must not be exceeded. Boats must contain adequate safety devices such as distress flares and personal flotation devices. Only boats designed and equipped for the purpose may be taken out to the open sea. A radio transceiver should be provided for vessels going more than two nautical miles offshore. Only licensed and appropriately trained personnel should be in charge of boats. Boats must be driven with caution and attention to prevailing conditions. Navigation skills may also be required. Only those personnel necessary and trained for the fieldwork may be carried in boats. The minimum size of a boating fieldwork party is two and at least one must be a competent swimmer.

Figure 2 shows the Wnet variation of the four CTRC configurations with t3, left side referring to the gasoline engine and right side referring to the diesel engine. Referring to Ref. [8] studying on the B-CTRC and the R-CTRC for a diesel engine of fishing boat, the variation trend of net power output is similar to the results in this paper. For the B-CTRC in Ref. [8], the net power output increases rapidly first with variation of t3 then becomes flat at high t3. This also can be found in the results in Figure 2. For the R-CTRC, the trend of net power output is both the same parabolic between the results in Ref. [8] and this study.

Electric Engine is one of the important consideration in converting a conventional diesel engine into electric ferry ecosystem. In selecting an electric motor, a wide investigation of what power engine is suitable for an existing boat. The parameters that need to consider are the water resistance, maximum hull speed of the boat, electric motor engine. The derived power engine is the minimum power can be used for the electric ferry implementation, the designer can increase the power of the electric engine according to the preferred speed.
A DA-based ECMS for energy optimisation of parallel diesel electric hybrid ship
Published in Ships and Offshore Structures, 2022
The single fishing cycle of tuna longline fishing vessel is 24 h as the simulation time. The power distribution between diesel engine and electric motor of hybrid fishing boat in one fishing cycle is shown in Figures 14 and 15. From the motor power output diagram and diesel engine output diagram, it can be seen that the simulation value is basically coincident with the experimental value, which verifies the correctness of the model.
