SOLAS II-2/10.2.1.4.1; Emergency FiFi pump piping running through E/R.

Reg. 10.2.1.4.1:

Isolating valves to separate the section of the fire main within the machinery space containing the main fire pump or pumps from the rest of the fire main shall be fitted in an easily accessible and tenable position outside the machinery spaces. The fire main shall be so arranged that when the isolating valves are shut all the hydrants on the ship, except those in the machinery space referred to above, can be supplied with water by another fire pump or an emergency fire pump. The emergency fire pump, its seawater inlet, and suction and delivery pipes and isolating valves shall be located outside the machinery space. If this arrangement cannot be made, the sea-chest may be fitted in the machinery space if the valve (sea inlet valve) is remotely controlled from a position in the same compartment as the emergency fire pump and the suction pipe is as short as practicable. Short lengths of suction or discharge piping may penetrate the machinery space, provided they are enclosed in a substantial steel casing, or are insulated to "A-60" class standards. The pipes shall have substantial wall thickness, but in no case less than 11 mm, and shall be welded except for the flanged connection to the sea inlet valve.

A.- When suction and Discharge piping penetrate E/R spaces, the pipe shall be protected by steel casing or shall be insulated to A-60 class, there fore the basic fire-resisting ability of the pipe shall remain intact during a period of 60 minutes. It is not necessary to insulate distance pieces, sea inlet valve and sea-chest. The discharge piping it is conclude to be the pipe running from the emergency fire pump discharge to the isolating valve. 


B.- The most common method to insulate a pipe to A-60 standard can be by covering and/or protecting the pipe with a steel faced mineral wool, which is approved as part of A-60 class division in accordance with the Fire Test Procedure Code.


C.- When sea inlet valve is inside E/R, this valve should not be fail close type in case the medium that move the valve actuator fail, instead fail open valve shall be use when remotely controlled. In my opinion this can be voided if the valve is opened/closed by a mecanical mean like a cardan joint intead control piping, actuacting devices and/or electric cables.

D.- In cases where main fire pumps are provided in compartments out side machinery spaces and where emergency fire pumps suction or discharge piping penetrate such spaces, above will be applied to the piping.

Nitrogen Oxides (NOx) Regulation 13.7; Marpol Annex VI; Pre-2000 Engines.

IMO at the 58Th session of the MEPC adopted MEPC 176(58) and introduce in 2008 Annex VI amendments, The revised MARPOL ANNEX VI become in to force on 01/07/2010, and under this amendments Tier I standards become applicable to existing engines installed on ships built between 1st January 1990 to 31st December 1999, with a displacement ≥ 90 litre per cylinder and rated output ≥ 5000 kW, subject to availability of approved engine upgrade kit. Before commonly known, as NOx control on Pre-2000 engines.


This NOx control on Pre-2000 engines will generally affect only the main engines on such ships, the 90 litre/cylinder criteria represents, for example in current medium speed engine designs, engines with a bore of 460 mm and above.

The amendments require on these engines: Either the installation of a certified “Approved Method”, not necessarily approved by the ship’s flag State but for any other administration on behalf of IMO that has certified an “Approved Method” which results in an emission value no higher than the relevant Tier I level for that particular engine model, rating and duty or the engine has been certified that operates within the limits set forth Tier I, II or III.

If compliance is demonstrated through The Approved Method, it must be applied no later than the first renewal survey which occurs more than 12 months after deposition of the advice to IMO.


However, if the ship owner can demonstrate that the Approved Method is not commercially available, by vessel’s flag administration confirmation, at that time then it is to be installed no later than the next annual survey after which it has become available. Given within regulation 13.7 are constraints on the Approved Method that limit its cost and detrimental effects on engine power and fuel consumption.

An approved Method shall include an approved Method File which accompanied the engine during its all life and where is stated the engine on board verification to confirm compliance during successive surveys.

Implementation of MARPOL VI, regulation 13.7 must be achieved by following the next steps:


• Ship constructed between 01/01/1990 and 31/12/2000 and the engine power > 5000 Kw and   displacement > 90 litres per cylinder?
No, no further action required.
Yes, engines details shall be added to the supplement attach to IAPP Certificate.

• Engine has been certified as being Tier I, II or II?
Yes, details to be added to the supplement. Engine in compliance with Reg. 13.7
No, below alternatives are possible.

• Engine has an Approved Method (A.M.) available?
No, no further actions required.
Yes, below alternatives are possible. However, Supplement must be updated as A.M. exists.

• Is vessel at first renewal survey, which occurs 12 month or more after notification to IMO and it was installed?
Yes, add to supplement that A.M. exists & A.M. Installed. Now vessel is in compliance with Reg. 13.7
No, below alternative is possible

• Is the vessel at next Annual Survey and Flag confirmed that the A.M. is not commercially available?
Yes, add to supplement that A.M. exists & A.M. no commercially available.
No, Flag shall be contacted and certificates withdraw “no in compliance”.

Emergency Position Indicating Radio Beacon (EPIRB)

Quantity Required: 1 pcs

Battery Life: 48 Hrs

Operating Temperature: -40ºC to +55ºC

An Emergency Position Indicating Radio Beacon (EPIRB) is used to alert search and rescue services in the event of an emergency. It does this by transmitting a coded message on the 406 MHZ distress frequency. This message is relayed via satellite and earth station to the nearest rescue co-ordination center.

EPIRB works with the Cospas-Sarsat polar orbiting satellite system, which provides true global coverage. The system has an alert delay of typically 45 minutes dependant to when the satellites come into view on the horizon. The satellite can determine the position of the EPIRB within 5 km (3 miles) and the coded message identifies the exact vessel to which the EPIRB is registered. This information allows the rescue services to eliminate false alerts and lunch an appropriate rescue.

The EPIRB has a secondary distress transmitter. This transmits on 121.5 MHZ and used for “homing” purposes. When the rescue services get close, this allows them to direction to find on the signal. To cater for searches at night, the EPIRB has a bright flashing light that aids final visual location.

 

Operational procedure

There are two way for activation of the EPIRB, one is manually and one is automatic thru HRU.

If the vessel is sinking and there is time to fetch the EPIRB then this should always be done. Remove the EPIRB from the mounting bracket. Once the liferaft is in the water, uncoil the lanyard and tie it to the liferaft, then throw the EPIRB overboard so that it floats next to the liferaft. The EPIRB will operate because its sea switch will activate, or you can manually activate it by sliding the door to the left and then momentarily pressing the ON button. (The on button is hidden behind a sliding door, which protects it from accidental activation. The sliding door has a temper seal to show if the EPIRD has been activated before.)

If there is not time to fetch the EPIRB. The EPIRB is supplied in a plastic enclosure. This is more than just a protective housing, it contains a sprung loaded lever, which automatically pushes the enclosure lid off and releases the EPIRB if your vessel sinks. A device called a Hydrostatic Release Unit (HRU) controls this automatic ejection. As the vessel sink, the enclosure fills with water. The HRU contains a blade, which is released due to water pressure acting on a diaphragm. Before it reaches a depth of 4 meters (13 feet), the HRU will operate and cut the plastic rod, releasing the spring coil. The spring pushes the EPIRB and enclosure lid outward. As the lid pivots off it disengages from the screw head that helped hold it in place.

The lid weighted so it rolls over and falls away. As the EPIRB floats away from the lid, it moves out of range of the magnet. Once away from the magnet its sea switch becomes armed. The EPIRB then floats on the surface with its strobe light flashing. 

When activated the EPIRB will start flashing immediately. It will make any distress transmissions for the first 50 seconds. This gives you a chance to turn it off, if you activated it accidentally. During the first 50 seconds the red lamp comes on continuously. When the red lamp starts to flash, the 50 seconds is over and distress transmissions have started.

To ensure the sea switch operates properly in rough seas, if has a built-in time delay. It has to be wet for at least 2 seconds before it will activate and it has to be dry for at least 8 seconds before it will de-activate.



New Amendments to SOLAS V/19; "BNWAS"

IMO resolution MSC.282(86) amended SOLAS Chapter V by adding two new requirements; "BNWAS" & "ECDIS". The dead line depend upon ship type, gross tonnage and keel laying. In this article, I will be dealing with Bridge Navigational Watch Alarm System (BNWAS).

The purpose of BNWAS is to monitor bridge activity and detect operator disability which can lead to marine accidents. The system alert the Master or another qualified Navigation Officer automatically if for eny reason the Officer on Watch (OOW) becomes incapable to perform his duties. This is achieved by a device with a serie of alarms, movement sensor and indications which are activated to alert in first instance (Pre-Warning) the OOW and, if he/she is not responding, then to alert (Alarm) the Master or another qualified OOW.

Applications Dates:

The system shall comply with following requirements:
 1.- Operational Modes:

• Automtic (Brought into operation whenever the ship is heading or track control system is activated)
• Manual ON (In operation constantly)
• Manual Off (Does not Operate under any circusntances)
• The system shall be provided with safety means to ensure access to control are limit to the Master (Key; Password; ETC)

2.- Sequence of indications and Alarms

• The system should remain counting for a period between 3 to 12 min, prior any indication.
• At the end of the settle period, pre-warning indication (visible only) at the bridge.
• If not reset, after 15 sec (First Stage) alarm shal be activated only in the bridge.
• If not reset, after another 15 sec (Second Stage) a remote audible alarm in the back up officer's and/or Master location shall be activated.
• If not reset, after 90 sec counted from the second 15 sec (third Stage) a remote audible alarm  at the locations of further crew's members shall be activated.
• In vessel other than passengers, the second or third stage alarm sound all at same time, the third stage alarm may be omitted.

3.- Reset Funtions

• Should not be possible to reset or cancel any alarm from any other place than the bridge.
• Should , by a single operator action, cancel the visual and all audible alarms and initiate a new dormant period. If rest is activated before the period is over new dormant period shall initiate.
• To initiate a reset funtion an imput by a single operator (OOW) action is required, it may be generated by a reset device or movement sensors distribiute on bridge.
• Continious activation of reset funtion should not prolong the dormant period.

4.- Emergency Call.

• May be provided to activate second and third stage alarms in case assistance is need on the bridge.

5.- Power Supply:

• From Main and Emegency, with automatic change over.
• Power Failure alarm shall be provided
• Power Failure of any navigational equipment shall not affect to any other piece of navigational equipment.
• Vessel with IBS notation additional power suply shall be provided (UPS)
