Q. 213) Co2 fixed fighting system maintenance
XMonthly inspections general visual inspection should be made of the overall system condition for obvious signs of damage, and should include verification that:
. all stop valves are in the closed position;
. all releasing controls are in the proper position and readily accessible for immediate use;
. all discharge piping and pneumatic tubing is intact and has not been damaged;
. all high pressure cylinders are in place and properly secured; and
. the alarm devices are in place and do not appear damaged.
In addition, on low pressure systems the inspections should verify that:
. the pressure gauge is reading in the normal range;
. the liquid level indicator is reading within the proper level;
. the manually operated storage tank main service valve is secured in the open position; and the vapour supply line valve is secured in the open position
Annual inspections
The following minimum level of maintenance and inspections should be carried out in accordance with the system manufacturer’s instructions and safety precautions:
1 the boundaries of the protected space should be visually inspected to confirm that no modifications have been made to the enclosure that have created uncloseable openings that would render the system ineffective;
2 all storage containers should be visually inspected for any signs of damage, rust or loose mounting hardware. Cylinders that are leaking, corroded, dented or bulging should be hydrostatically retested or replaced;
3 system piping should be visually inspected to check for damage, loose supports and corrosion. Nozzles should be inspected to ensure they have not been obstructed by the storage of spare parts or a new installation of structure or machinery;
4 the manifold should be inspected to verify that all flexible discharge hoses and fittings are properly tightened; and
5 all entrance doors to the protected space should close properly and should have warning signs, which indicate that the space is protected by a fixed carbon dioxide system and that personnel should evacuate immediately if the alarms sound. All remote releasing controls should be checked for clear operating instructions and indication as to the space served
Minimum recommended maintenance
At least biennially (intervals of 2 years ± 3 months) in passenger ships or at each intermediate, periodical or renewal survey* in cargo ships, the following maintenance should be carried out
1 all high pressure cylinders and pilot cylinders should be weighed or have their contents verified by other reliable means to confirm that the available charge in each is above 90% of the nominal charge. Cylinders containing less than 90% of the nominal charge should be refilled. The liquid level of low pressure storage tanks should be checked to verify that the required amount of carbon dioxide to protect the largest hazard is available;
2 the hydrostatic test date of all storage containers should be checked. High pressure cylinders should be subjected to periodical tests at intervals not exceeding 10 years. At the 10-year inspection, at least 10% of the total number provided should be subjected to an internal inspection and hydrostatic test**. If one or more cylinders fail, a total of 50% of the onboard cylinders should be tested. If further cylinders fail, all cylinders should be tested. Flexible hoses
should be replaced at the intervals recommended by the manufacturer and not exceeding every 10 years; and
3 the discharge piping and nozzles should be tested to verify that they are not locked. The test should be performed by isolating the discharge piping from the system and flowing dry air or nitrogen from test cylinders or suitable means through the piping.
At least biennially (intervals of 2 years ± 3 months) in passenger ships or at each renewal
survey* in cargo ships, the following maintenance should be carried out by service technicians /specialists trained to standards accepted by the Administration
1 where possible, all activating heads should be removed from the cylinder valves and tested for correct functioning by applying full working pressure through the pilot lines. In cases where this is not possible, pilot lines should be disconnected from the cylinder valves and blanked off or connected together and tested with full working pressure from the release station and checked for leakage.In both cases this should be carried out from one or more release stations when
Installed If manual pull cables operate the remote release controls, they should be checked
to verify the cables and corner pulleys are in good condition and freely move and do not require an excessive amount of travel to activate the system;
.2 all cable components should be cleaned and adjusted as necessary, and the cable connectors should be properly tightened. If the remote release controls are operated by pneumatic pressure, the tubing should be checked for leakage, and the proper charge of the remote releasing station pilot gas cylinders should be verified. All controls and warning devices should function normally, and the time delay, if fitted should prevent the discharge of gas for the required time period; and
3 after completion of the work, the system should be returned to service. All releasing controls should be verified in the proper position and connected to the correct control valves. All pressure switch interlocks should be reset and returned to service. All stop valves should be in the closed position
Q. 214) What are the various methods of refloating a vessel ?
X1.Ground tackle
2.Tugs
3.Dredging craft
4.Even lighters into which to discharge of cargo.
5.Perhaps the hauling power of large vessels.
GROUND – TACKLE: If vessel not in tidal water, secure vessel with ground tackle. This is meant for the use of anchors, carefully placed at considerable distances from the ship, and connected to her by heavy wire hawsers, possibly using some lengths of her chain cable. Heavy purchases are then rigged, often one secured to the hauling part of the other to give greater mechanical advantage and lower stresses on the final hauling part, to impose a stress upon these anchors. This stress, which must be applied continuously, is beneficial in re-floating the ship.
STATE OF TIDE: While re-floating must be rising tide.
TIDAL RANGE : Check the draft of the ship and compare it with the estimated draught prior to impact. The difference in cm multiplied by the tones per cm immersion indicates the amount of lost of buoyancy. The tidal range may provide this required buoyancy at high water or even before.
DISCHARGED: Water tanks may be discharged in order to provide the required buoyancy.
NATURE OF BOTTOM: ideally, a survey should be made of the surrounding sea-bed, noting depths and material. The sea-bed formation in some localities changes with every tide making initial surveys unreliable. Some beaches are subject to strong cross-currents and scouring by surf. A survey will indicate the best possible direction for re-floating.
LEGAL SITUATION: The owners and Llyod’s Agent should be informed as soon as possible. The underwriters will then be notified. At the next port of all protest should be noted, and a survey of the hull and machinery carried out. A certificate of Seaworthiness should be obtained before proceeding.
Q. 215) What is notation of class
XClassification notations are indicative of the specific Rule requirements which have been met.
Additional voluntary notations are offered by individual Societies and may be selected by an owner wishing to demonstrate that the vessel conforms to a particular standard that may be in excess of that required for classification.
Depending on the Classification Society, the classification notations are assigned to the ship according to ship type, service, navigation and/or other criteria which have been provided by the owner and/or builder, when requesting classification.
Q. 216) Objective of isps
X1.establish an international framework involving co-operation between various parties to detect/assess security threats and take preventive measures
2.to establish the respective roles and responsibilities of all these parties concerned, for ensuring maritime security
3.to ensure the early and efficient collation and exchange of security-related information
4.to provide a methodology for security assessments so as to have in place plans and procedures to react to changing security levels
5.and to ensure confidence that adequate and proportionate maritime security measures are in place.
The objectives are to be achieved by the designation of appropriate security officers/personnel on each ship, in each port facility and in each shipping company to prepare and to put into effect the security plans that will be approved for each ship and port facility.

Q. 220) What is the latest amendment with respect to tank coating on oil tankers ?
XFollowing incidents resulting from structural failure in oil tankers, the IMO developed requirements aimed at inhibiting
corrosion in cargo oil tanks by way of performance standards. These performance standards are now being made
mandatory by an amendment to SOLAS: regulation II-1/3-11, Corrosion Protection of Cargo Oil Tanks of Crude Oil Tankers,
adopted by Resolution MSC.291(87).
The legislation applies to new crude oil tankers of 5,000 dwt or above engaged on international voyages as follows:
• Contract date: 1 January, 2013
• Keel laying date: 1 July, 2013
• Delivery date: 1 January, 2016
The regulations provide three options to address the corrosion protection in these areas
Option 1 – Coating
The first option requires the coating of cargo oil tanks during the construction of the ship in accordance with the
‘Performance Standard for Protective Coatings for Cargo Oil Tanks of Crude Oil Tankers’
Option 2 – Alternative means: Corrosion-resistant steel
The second option allows cargo oil tanks to be protected by what the regulation refers to as “alternative meansâ€. One such
example is the use of “corrosion-resistant†steels which have the goal of maintaining the required structural integrity for 25 years
Option 3 – Exemption
The regulations allow a third option, in which a vessel’s flag state may choose to exempt a crude oil tanker from the
requirements described in option 1 and option 2, if the vessel is built solely to carry cargoes or perform cargo handling
operations with cargoes which do not cause corrosion
Where the cargo oil tanks are coated or protected by the use of corrosion-resistant steels in accordance with the IMO
regulations, Lloyd’s Register’s verification shall be indicated by the class notation ShipRight ACS(C), where ACS denotes
anti-corrosion system and C denotes cargo oil tanks.
Areas to be protected.
1) Deckhead with complete internal structure, including brackets connecting to longitudinal and transverse
bulkheads. In tanks with ring frame girder construction the underdeck transverse framing to be protected
down to level of the first tripping bracket below the upper faceplate.
2) Longitudinal and transverse bulkheads to be protected to the uppermost means of access level. The uppermost
means of access and its supporting brackets to be fully protected.
3) On cargo tank bulkheads without an uppermost means of access the protection to extend to 10% of the
tank’s height at centreline but need not extend more than 3 m down from the deck.
4) Flat inner bottom and all structure to height of 0.3 m above inner bottom to be protected.
