performance standard for non-mandatory types of
simulation.
An example is the solution proposed by Texas A&M
University in Galveston (USA) [3]. Similar solutions are
available in other MET centres, which are based on
complete computer simulation systems, where all push
buttons, instrumentation and switches are virtual
(touchscreen simulator), for example [4]. Another
approach is the concept of building hybrid simulators,
which include the use of real elements, such as control
consoles, switchboards, in which only the front
equipment corresponds to reality. An example is the
ship engine simulator at the Faculty of Marine
Engineering at GMU [5]. Yet another solution is that
one important element of the system is real, and the
remaining elements are in the area of computer
simulation. An example is the Neptune System by
Königsberg Maritime [6]. In this solution the simulator
is dedicated to conducting courses for crew members
on ships, and only one HV (high voltage) circuit
breaker field is real and the rest of the system is in the
virtual service area.
Another approach was maritime education based
on real systems. One of the solutions dedicated to this
problem were training ships, which were specially
designed for this purpose. Historically, in Poland,
special ships were used for this task in the 1980s, m/v
Antoni Garnuszewski and m/s Kapitan Leduchowski.
These ships fulfilled their role as merchant ships, but at
the same time they were equipped with a so-called
training ship engine room and a double bridge, one of
which was a bridge used only for training purposes.
On the other hand the training engine room was
equipped with all the systems necessary for the
operation of the ship, except for the main engine. It is
worth emphasizing that this ship was equipped with
high-voltage elements (3,3kV) such as a generator,
loads and switchboard as part of the training power
system. This solution allowed for good practical
preparation not only of future navigating officers but
also of mechanical and electrical officers. However, this
model of education did not stand the test of time,
especially in regarding to the engine crew, and as a
consequence, practical education is based on currently
available simulators and practice on ships. It should be
noted that currently, in relation to ETO, apart from
computer simulators, training is still based on physical
stations where real operational problems related to the
ship's electrical power system can be presented [7-10].
It is worth emphasizing the discussions on the use
of virtual reality in simulators or the use of remote
simulators located in the cloud and new challenges
resulting from operating of future autonomous ships
are continuosly developed [11].
Each solution has its advantages and
disadvantages, but there is one common denominator,
which is the purpose for which different types of
simulators are used. The main purpose of simulators
use is to prepare trainees as best as possible to operate
ship systems and devices. However, as part of their
duties, watchkeeping crew members not only operate
the devices but are also responsible for maintaining
them in good technical condition. In this case, despite
the various virtual tools available, an important
element of education is the contact of trainees with real
devices. One of such positions in ship engines is the
ETO, who rarely operates devices. However, its main
task is to take care of the efficiency of devices in the
broadest sense of the word electrical by conducting
appropriate service, inspections and, in the event of
damage, diagnostics and possibly repairs. Very often,
ETO’s start performing their tasks on devices that are
already out of order. Therefore, ETO’s need other
competencies than just efficient service to perform their
tasks. Often, in-depth knowledge is needed in relation
to the construction and operating principles of systems
and devices, not only electrical, but also mechanical,
hydraulic, refrigeration or pneumatic, which are
controlled by electrical systems (electronic or
computer). The aforementioned preparation is difficult
to implement based only on work with devices as part
of internships on ships, especially in the field of
electrical, electronic and control engineering. This
mainly concerns the area of service, diagnostics and
repairs. The minimum training requirements for ETO
were specified only in the STCW 2010 convention [2],
and they are mainly focused on defining competences
in the field of maintaining the efficiency of electrical,
electronic and control devices, including routine and
ad hoc inspections and repairs. It should be
remembered that the convention requirements also
concern appropriate competencies in relation to the
broadest sense of safety and environmental protection
[12, 13].
It is worth noting that the STCW Convention
defines minimum requirements and there are no
formal obstacles to expanding the scope of
competences within the curricula of individual MET
units to meet new challenges resulting from
technological development [14].
To meet new challenges and the specifics of ETO
work, a physical simulator of a ship power plant was
built at the GMU Faculty of Electrical Engineering. It is
worth emphasizing that it can be a good supplement in
the education of future marine engineers and
navigators.
2 REAL ON BOARD JOB DESCRIPTION OF AN
ELECTRO-TECHNICAL OFFICER
Work on a ship is significantly different from work on
land. This translates into the selection of crew members
not only in terms of substantive skills, but also a great
deal of emphasis is placed on psychological,
sociological, and health aspects. To evaluate the
required competencies, it is not enough to consider the
three functions and related 18 competencies in Table A-
III-6 [2] but also we should to precise the relationship
among them as well as some other factors being
enclosed below. Three functions referred to the ETO
operational level are: -Electrical, electronic, and control
engineering at operational level (7 competencies);
Maintenance and repair at operational level (5
competencies); -Controlling the operation of the ship
and care for person on board at operational level (6
competencies).
At this point, it is worth noting that the STCW
convention has a major inconvenience that applies to
the entire document, in which the required educational
and training tasks are given in tables without
