RULES FOR BUILDING AND CLASSING

STEEL VESSELS FOR SERVICE ON RIVERS AND

INTRACOASTAL WATERWAYS2007

NOTICE NO. 6 October 2008

The following Rule Changes were approved by the ABS Rules Committee on 3 June 2008and become EFFECTIVE AS OF 1 JANUARY 2009.

(http://www.eagle.org/absdownloads/index.cfm for the consolidated version of the Rules for Building andClassing Steel Vessels for Service on Rivers and Intracoastal Waterways 2007, with all Notices and

Corrigenda incorporated.)

Notes - The date in the parentheses means the date that the Rule becomes effective for new constructionbased on the contract date for construction, unless otherwise noted. (See 1-1-4/3.3 of the ABS

Rules for Conditions of Classification (Part 1).)

PART 4 VESSEL SYSTEMS AND MACHINERY

CHAPTER 2 PROPULSION AND MANEUVERING MACHINERY

SECTION 1 PROPULSION SHAFTING

13 Tail Shaft Liners

13.1 Thickness at Bearings

(Revise Subparagraph 4-2-1/13.1.1 and add new Subparagraph 4-2-1/13.1.2, as follows.)

13.1.1 Bronze Liner(2009)

The thickness of bronze liners to be fitted to tail shafts or tube shafts is not to be less than that

given by the following equation:

t= T/25 + 5.1 mm t= T/25 + 0.2 in.

where

t = thickness of liner, in mm (in.)

T = required diameter of tail shaft, in mm (in.)

13.1.2 Stainless Steel Liner(2009)

The thickness of stainless steel liners to be fitted to tail shafts or tube shafts is not to be less

than one-half that required for bronze liners or 6.5 mm (0.25 in.), whichever is greater.

2 ABS RULES FOR BUILDING AND CLASSING STEEL VESSELS FOR SERVICE ON RIVERS & INTRACOASTAL WATERWAYS .2007

(Add new Paragraph 4-2-1/13.15, as follows.)

13.15 Stainless Steel Cladding (2009)

Stainless steel cladding of shafts is to be carried out in accordance with an approved procedure. See

Appendix 7-A-11, Guide for Repair and Cladding of Shafts of the Rules for Survey AfterConstruction (Part 7).


CHAPTER 3 PUMPS AND PIPING SYSTEMS

SECTION 6 CARGO SYSTEMS

1 Vessels Carrying Oil in Bulk Having a Flashpoint of 60C

(140F) or Less

1.5 Other Piping Systems

(Revise Subparagraph 4-3-6/1.5.1, as follows.)

1.5.1 Pump Room and Cofferdam Bilge Systems (2009)

Provision is to be made for removing drainage from the pump room bilges and adjacent

cofferdams. A separate bilge pump, eductor or bilge suction from a cargo pump or cargostripping pump may be provided for this purpose. The pump is not to be located in, nor is the

piping to pass through, spaces containing machinery where sources of vapor ignition are

normally present. Where a bilge suction is provided from a cargo or stripping pump, a stop-

check valve is to be fitted in the bilge suction branch. An additional stop valve is to be fitted

when the bilge suction branch is arranged so that it may be subjected to a head of oil from the

filling line. Pump room bilge suction and discharge valves and bilge-pump controls are to be

operable from in the pump room, unless Flag Administrations have a specific requirement for

remote operation, either from an accessible position outside the pump room or from the pump

room casing above the freeboard deck. High levels of liquid in the pump rooms bilge are to

activate an audible and visible alarm in the cargo control room and on the navigation bridge

CHAPTER 4 FIRE EXTINGUISHING SYSTEMS AND EQUIPMENT

SECTION 1 ALL VESSELS

17 Shutdowns and Closures

(Revise Paragraph 4-4-1/17.1 and add new Paragraph 4-4-1/17.3, as follows.)

17.1 Ventilation Fans and Openings (2009)

Means are to be provided for stopping ventilating fans serving machinery and cargo spaces, and for

closing all doorways, ventilators and other openings to such spaces. These means are to be capable of

being manually operated from outside of such spaces in the event of a fire. See 4-5-2/17.1.1.

17.3 Other Auxiliaries (2009)Machinery driving forced- and induced-draft fans, oil-fuel transfer pumps, oil-fuel unit pumps and

other similar fuel pumps, fired equipment such as an incinerator, lubricating oil service pumps,

thermal oil circulating pumps and oil separators (purifiers) are to be fitted with remote shutdowns

situated outside of the spaces concerned so that they may be stopped in the event of a fire arising in

the space. This need not apply to oily water separators. See 4-5-2/17.1.2.

In addition to the remote shutdowns required above, a means to shutdown the equipment is to be

provided within the space itself.


CHAPTER 5 ELECTRICAL INSTALLATIONS

SECTION 2 SHIPBOARD SYSTEMS

17 Fire Protection Systems

17.1 Emergency Stop


17.1.2 Fuel Oil Units (2009)

See 4-4-1/17 for emergency tripping and emergency stop for other auxiliaries, such as forced

and induced draft fans, fuel oil units, lubricating oil service pumps, thermal oil circulating

pumps and oil separators (purifiers).

SECTION 4 MACHINERY AND EQUIPMENT

7 Switchboards, Distribution Boards, Controllers, etc.

7.11 Bus Bars, Wiring and Contacts


7.11.7 Terminals (2009)

Terminals or terminal rows for systems of different voltages are to be clearly separated from

each other. The rated voltage is to be clearly indicated at least once for each group of

terminals which have been separated from the terminals with other voltage ratings. Terminals

with different voltage ratings, each not exceeding 50 V DC or 50 V AC may be grouped

together. Each terminal is to have a nameplate indicating the circuit designation.



SECTION 6 SPECIALIZED VESSELS AND SERVICES

9 Passenger Vessels

9.9 Manually Operated Alarms


9.9.1 General Emergency Alarm System (2009)

9.9.1(a) The general emergency alarm system is to be capable of sounding the generalemergency alarm signal consisting of seven or more short blasts followed by one long blast onthe vessels whistle or siren and additionally on an electrically operated bell or klaxon or other

equivalent warning system, which is to be powered from the vessels main supply and theemergency source of electrical power required by 4-5-6/9.1, as appropriate. The system is to

be capable of operation from the navigation bridge and, except for the vessels whistle, alsofrom other strategic points.

9.9.1(b) There are to be not less than two sources of power supply for the electricalequipment used in the operation of the General Emergency Alarm System, one of which is to

be from the emergency switchboard and the other from the main switchboard. The supply is

to be provided by separate feeders reserved solely for that purpose. Such feeders are to run to

an automatic change-over switch situated in, or adjacent to, the main general emergency

alarm control panel.

9.9.1(c) An alarm is to be provided to indicate when there is a loss of power in any one of the

feeders required by 4-3-2/17.1.2(b).

Notice No. 6 October 2008


9.9.1(d) As an alternative to two feeders as described in 4-3-2/17.1.2(b), a battery may beconsidered as one of the required sources, provided the battery has the capacity of at least 30

minutes of continuous operation for alarming and 18 hours in standby. A low voltage alarm

for the battery and the battery charger output is to be provided. The battery charger is to be

supplied from the emergency switchboard.9.9.1(e) The system is to be audible throughout all the accommodation and normal crewworking spaces and open decks. The alarm is to continue to function after it has beentriggered until it is manually turned off or is temporarily interrupted by a message on the

public address system.
