2.2. Порядок подготовки судоводителей для судов с сдп

Introduction

Since 1984 The Nautical Institute has administered a training programme intended to provide a verifiable level of competency for DP Operators. This scheme was developed as a result of the deliberations of a Working Committee, consisting of serving experienced DP masters, operations managers, representatives from the DTp, DoE, UKOOA and the AODC, together with those concerned with training matters.

The progress of a trainee through The Nautical Institute scheme is witnessed by means of records kept in a logbook. The trainee keeps his/her own logbook and is responsible for maintaining the records up to date. DP logbooks may be obtained from The Nautical Institute. The logbooks contain space for entries relating to the completion of each of the six phases of training recommended within the scheme. The six phases are:

  1. Satisfactory completion of a shore-based DP Induction or Basic Operators' course.

  2. Sea-going DP familiarisation. A minimum of 30 days aboard a DP-capable vessel.

  3. Satisfactory completion of a shore-based DP Simulator or Advanced Operators' course.

  4. Satisfactory completion of six months supervised DP operations.

  5. Having completed phases 1 to 4 above, the trainee DPO must obtain verification from the master of his/her vessel as to the suitability of the trainee to undertake full watch keeping responsibility on board the vessel.

  6. Issue of the certificate.

Although the majority of courses conducted at phases 1 and 3 above are organised and run by nautical colleges or other training establishments, these phases may also be conducted on board the vessel. The arrangements for the conduct of such training will be subject to inspection and approval by The Nautical Institute DP Validating Committee, just as with any shore-based training establishment requiring approval.

Phase 1. The DP Induction Course

This course is normally run at a shore-based establishment, either a Nautical College or at the premises of one of the manufacturers of DP systems. The induction course is of four or four-and-a-half days duration and provides a balanced introduction to the principles and practice of DP operations and systems. The induction course is intended for ships' officers already qualified as watchkeepers, but with little or no DP experience. A space is provided in The Nautical Institute DP Logbook for the recording of the completion of this course.

Phase 2. Seagoing Familiarisation

The DP logbook contains a familiarisation log listing various activities to be completed during this one-month period. It is not necessary for the vessel to be engaged in DP operations for the whole of this period, as some of the activities may be completed with the vessel underway or even alongside. The successful completion of each activity must be endorsed with the signature of the vessel's master.

Phase 3. The DP Simulator Course

This shore-based course is, again, of four or four-and-a-half days duration. It is conducted at a training centre equipped with a sophisticated and capable DP simulator facility. This course is intended for those who have successfully completed phases 1 and 2 of The Nautical Institute scheme. The DP simulator course provides the trainee with the opportunity to plan and conduct DP operations using a shore- based DP system. This system is interfaced with a simulator and is able to provide trainees with realistic simulation of DP scenarios, including error and failure mode simulation. This type of course provides realistic training in a safe environment, without incurring the risks that would accompany any such training conducted using the real-ship environment.

Phase 4. Supervised DP Watchkeeping

This phase is intended to allow the consolidation of the various training experiences and to build up experience in the variety of tasks and operations conducted by DP vessels. As with phase 2, space is provided in the DP logbook for this experience to be detailed, suitably endorsed by the master of the vessel/s.

Occasionally, a question will be asked relating to the number of hours completed on the DP console, what number of hours constitutes a month and so on. Since The Nautical Institute scheme is based upon verifiable documentation, the only values that can be quantified here are elapsed days and months. Time spent on board, time signed on articles, etc are the only quantities that may be directly verified. Thus phases 2 and 4 of the scheme are related to days and months service in DP vessels. Nevertheless, the intention is that the candidate should, at phase 4, be a watchkeeping member of the bridge team and not simply serving in a DP vessel. A trainee DPO may, at phase 4, serve as "2nd man" on the bridge watchkeeping team, serving with a fully qualified DPO. Some companies may allow for a trainee at phase 4 to serve as 3rd man on the bridge, with two fully qualified DPOs on watch. IF this is the case, then it is important that the trainee receives sufficient experience to be able to benefit from the completion of phase 3.

Phase 5. Assessment of Suitability

This assessment is intended to be carried out by the master of the vessel in which the candidate completed his/her DP watchkeeping within phase 4 of the scheme. It constitutes the only actual assessment of the competence of the DOP candidate and places the responsibility for that assessment with the person best able to comment upon the DPO candidate's competence. This assessment is recorded in the DP logbook. Once this has been completed, the logbook may be forwarded to The Nautical Institute together with any supporting documentation. If all is in order, the candidate will be issued with his/her DP Operator's Certificate (phase 6).

Levels of DP Certificate

The Nautical Institute issues two levels of DPO certificate: Full and Limited.

The full certificate is issued to those whose sea time has been spent working in vessels of Equipment Class 2 or 3. In order to acquire an unlimited (full) certificate the officer must meet the following requirements:

  1. Six months documented practical experience in the use of DP systems on units/vessels operating in Equipment Class 2 or 3, or twelve months documented practical experience in the use of DP systems on units/vessels operating Equipment Class 1.

  2. If this experience is from units/vessels that spend more than 50% of their operational time on DP, one month's practice on units/vessels operating Equipment Class 2 or 3 is required in addition.

  3. If the experience is in units/vessels which spend less than 50% of their operational time on DP (e.g. shuttle tankers or supply ships), two months practice on units/vessels operating Equipment Class 2 or 3 in addition.

  4. The platform manager/captain on the Equipment Class 2 or 3 vessel shall give written confirmation that the operator has the necessary practical experience and that he assumes him qualified as a DP operator.

Any officer who has undertaken the complete scheme of training, but whose service has been limited to vessels of Equipment Class 1, i.e. where a loss of position may occur in the event of a single fault – will be issued with a certificate endorsed with the word "Limited".

For details relating to the equipment classes referred to above, see IMO MSC/Circular 645, Guidelines for Vessels with Dynamic Positioning Systems, 1994. A resume of the provisions of these guidelines is contained within The Nautical Institute DP Operators Logbook.

The scheme described on the previous page has been running since 1984 and, as detailed

elsewhere, a number of shore-based establishments are approved for the purpose of conducting formal courses fulfilling the requirements of phases 1 and 3 of the scheme. The scheme is generally accepted as being the worldwide standard. The Nautical Institute maintains a central register of all certification issued, with appropriate details.

Notes on the Completion of The Nautical Institute DP Logbook

Nautical Institute DP Logbooks are available from The Nautical Institute. They are issued free of charge to all persons attending the DP induction course. The logbook is the property of the holder and must be looked after carefully. All sections must be properly completed. On receipt the holder must fill in name, address and date of birth, also discharge book or passport number and number and grade of certificate of competency. When courses are attended, the holder must ensure details are entered in the appropriate logbook page, signed and stamped by the course instructor on satisfactory completion.

The seagoing phases of the scheme should be recorded in the logbook, accompanied by the master's signature and the vessel's stamp. At the end of the training period, the master must sign and endorse section F in the logbook. When the logbook is complete it should be sent to The Nautical Institute, 202 Lambeth Road, London SE1 7LQ. The Institute will verify the following information:

  • Signed evidence of seatime

  • Stamped evidence of courses attended

  • Verification by the master in section F

  • Types of equipment and classes of vessels

  • DP systems in use

  • Education and certificate of competency.

Extra vetting is carried out by random verification that the data is correct by contacting companies, colleges, vessel masters and other individuals. If all the data is correct the Institute will issue a numbered and dated certificate, record the information in the logbook and aim to return it within one week by first class mail or airmail overseas.

Mature Entry to the Scheme

It is recognised that some officers may have served in DP vessels as watchkeeping DPO without having completed any formal training courses. It is not the intention of The Nautical Institute scheme to penalise such officers by insisting that they commence the training at phase 1. However, the Institute does require a formal assessment to ensure that the candidate fully understands and can use the whole DP system. It may well be that the candidate may be eligible to qualify for issue of the DPO certificate by completing phase 3 of the scheme, supported by sufficient DP watch keeping sea service and the completion of the assessment by the master of the vessel (phase 5).

It is not the intention that an officer commences his/her DP training simply by omitting phase 1 of the scheme, gaining some watchkeeping sea service and then completing the DP simulator course. Mature entry to the scheme is a concession that will be judged on individual merit on a case-by-case basis. It has always been the intention of The Nautical Institute that a new entrant to DP work undertakes the full scheme including both shore-based training courses.

There are two reasons for making this requirement. When DP vessels are working there is little time for training (especially on Equipment Class 1 vessels) and there is no room for error. Sea staff have reported back consistently that it is desirable that new DPOs should have completed an induction course before joining the vessel. Employers should not plan to train DP personnel by omitting any phase of the recommended scheme.
