Guideline for the control and safeguarding of the machinery installation for unattended engine room
The objective of this guideline is to provide guidance for the required arrangements for the control and safe guarding of the rnachinery installation in an unattended engineroom, the docurnentation to be submitted and surveys to be carried out. This in order to comply with Art. 114, paragraph4 of the Netherlands' Shiping Order 1965.
I. Ships applying for Netherlands' registry after 1 April 2000.
The following requirements and notations apply:
For ships, not being a small vessel
- the remote control-, alarm-, communication- and automation systems shall comply with the regulations of part C and E of Chapter II-1of Solas 1974 as amended. With the exeption that for ships of less than 500 GT it is not required that the second means for communicating orders (see Solas Ch. ll-1 Reg.37.1) from the bridge to the engine-room is anengine-room telegraph and;
- the machinery installation shall comply with the "Rules for automated and remotely controlled systems" of the Recognized Organisation (RO), and;
- the ship shall be assigned with the additional class notation for "unattended engine room "of the RO and;
- on ships of more than 500 tons a personnel alarm shall be installed in the engine room.
This personnel alarm shall comply with the requirements of NSI, as attached to this guideline.
For ships being a small vessel
The remote control-,alarm-, cornmunication- and autornation systems shall comply with the NSI requirements for this type of ship, see NSI edition" Regulations Small Vessels"
small vessel = a vessel with a Ioadlines length of less than 24 m and less than 500 GT, used or intended for use in a restricted trading area of 30 nautical miles from the coast, not being a passengership for international voyages or for overnight voyages.
Submisslon of documentation
The RO shall submit to NSI one copy of the following documents, stamped, signed and in good time:
Drawings,diagrams and descriptions of:
- remote control systems, inclusive bridge control
- alarm systems, inclusive list of alarm points
- automation systems(not required for ships transferring to Netherlands)
Testing of systems RO shall perform the tests required for the "unmanned engineroom" notation. The tests shall at least include the following:
- alarm systems, included alarm points
- safety systems, included safety- and protective devices
- stand-by function pumps
- alarms machine installation on bridge
- (shaft) generating sets under Ioad
- parallel running and Ioad share of the generating sets
- automatic start of the generating sets after a black-out
- emergency generating set under Ioad
- automatic start of emergency generating set
- emergency stop of propulsion machinery from bridge
- Iocal (emergency)control propulsion machinery
- transfer of control position propulsion machinery
- bridge control
- fire detection installnation(srnoke test dudrig seatrials)
- general engineers alarm
- steering gear alarms
- main enginetest run (docktrial)
- seatrials to demonstrate the correct operation off all automation equipment and systems in operation at sea.
AII tests shall be recorded in checklists or other type of reports and are to be submitted to a NSI surveyor, also on board of the ship, on request.
Ships transferring to the Netherlands' registry shall be in the possession of a valid "unmanned engineroom" notation ans certificate of RO.
NSI will issue the Safe Manning Document with a suitable manning for unmanned engine room as soon as RO has notified NSI that class certificate with "unmanned engineroom" notation or that the notation has been issued or confirmed.
II.Existing Netherlands ships with unmanned engine room in accordance with NSI requirements
Existing Netherlands ships with unmanned enginerooms which have been constructed in accordance with NSI requirements, but without a valid "unmanned engine room" notation from RO, may continue to sail without change in certification and inspection regime.
This means an annual inspection of the alarm lists by RO and a 5 yeary inspection of the system by NSI.
On a voluntary base the owner may opt for RO notation. In that case the procedure described in I. is applicable.
Attachment to NSI Guideline for unmanned engine rooms
Specifications for the Personnel Alarm in the engine room for ships to which the Netherlands 'Shipping Act is applicable
Art. 1 On ships of 500 GT and more, with a sea watch of less than 2 persons in the engine room, a personnel alarm (P.A.) shall be installed
Art. 2 After switching on, the P.A.shall give after not more than 27 minutes, automatically a visual and audible alarm in the engine room.
By acceptation of this alarm the P.A.shall be reset to the initial position, affer which a new cycle of 27 rninutes status.
If this alarm is not accepted within 3 minutes the engineers' alarm shall be activated by the P.A.
Art. 3 By means of a reset push button at the E.C.R. station (space where the main alarm panel is Iocated) the P.A. can be reset to the initial postion.
Various reset push buttons rnay be installed throughout the engine room.
Art. 4 The P.A. is to be put into operation:
.1 in case of 1-man watch keeping, whereby the P.A. is in operation continiusly.
.2 in case of unattended engine room by the engineer on duty or an other engine rating when attending the engine toom.
.3 in case of unattended engineroom when the engineer on duty has to attend the engine room for a machinery alarm.
Art. 5 In case of unattended engine room the P.A. is to be switched off manually after leaving the engine room,, but it remains in the stand-by postion for the next switching on, rnanually or automatically.
Art. 6 Manually putting into operation as well as switching off the P.A. shall take place outside the engine room near the entrance(s) which is (are) normally used.
Art. 7 Other means which give, to the satisfaction of the Head of the Shipping Inspectorate, an equivalent level of protection can also be accepted.
