OVERVIEW

This course provides participants with basic knowledge of Dynamic Positioning (DP), the principles and practical use of DP systems.

CONTENT
This course involves both theory and practice on a simulated DP system and covers the following topics:

– Principles of DP.
– Elements of the DP system.
– Practical operation of the DP system.
– Position reference systems.
– Environment sensors and ancillary equipment.
– Power generation and supply and propulsion.
– DP operations.

On successful completion of both the Induction Course and Induction online exam, the trainee DPO will be issued with an NI DP logbook in which the courses, DP sea time, tasks and the Statement of Suitability are recorded. The subsequent DP sea time following the Induction Course provides the opportunity to complete the task sections in the logbook.
The new grey logbook is only issued to trainee DPOs that started their training after 1st January 2015. Trainee DPOs who have entered into the training scheme before this date or are repeating the Induction Course shall continue to use their existing logbooks.

OURSE PRE-REQUISITES
The course is designed for Deck Officers, Engineer Officers and personnel working toward an STCW Certificate of Competency (COC) who wish to start The Nautical Institute’s DP Operator Training Scheme.

Participants must hold appropriate STCW certification, or state equivalent or be studying towards an appropriate recognized certificate. Please note that participants may only accrue a maximum of 30 days’ recognized seatime on completion of this course as a cadet or trainee. Please see www.nautinst.org or contact FSOSC for further information.

NUMBER OF HOURS
A minimum of 28 hours of teaching time is required for this course; if additional time is required to run exams or deal with paperwork, this time shall be added to the 28 hours. It is expected that 80% of the time is spent on teaching DP theory and 20% on practical exercises. Usually, the Induction Course is delivered over four or five days. There is an option to deliver the course over a maximum six-week period, with instruction taking place on a given day in each of those weeks. This option is particularly suited to cadet training institutions as it allows the training to fit into the already existing class schedule. In all other aspects, the course must conform to all other training scheme standards.

ONLINE ASSESSMENT
In order to be awarded a certificate of completion for the Induction Course, the trainee must pass an online assessment at the training centre. The exam is composed of multiple choice questions and shall be completed in 1 hour 15 minutes. The online assessment will consist of 40 questions and shall be completed in one hour with a pass mark of 70%.
Students who fail at the first attempt are allowed to have another two attempts within six months of the first attempt; however, the second attempt must be undertaken within 96 hours of the first attempt. Failing these three initial attempts, the student is required to repeat the Induction Course and undertake the assessment again. On successful completion of the Induction Course and online assessment, the trainee Dynamic Positioning Operator will be issued with a Nautical Institute Dynamic Positioning Operator’s logbook in which his/her courses, DP sea time, task completion and Statement of Suitability as a DPO are recorded.

COURSE AIMS
At the end of the course the student should:

– Have acquired knowledge of the principles of DP.
– Have acquired a basic understanding of how to set up a DP system.
– Have an understanding of the practical operation of associated equipment, including position reference systems.
– Be able to recognize the various alarm, warning and information messages.
– Be able to relate the DP installation to the ship system, including (but not limited to) power supply, maneuvering facility, available position reference systems and nature of work.
– Be able to relate DP operations to the existing environmental conditions of wind, sea state, current/tidal stream and vessel movement.
