Five-year service hydrostatic testing for all SCBA cylinders; and control valves of fixed fire- fighting systems should be internally inspected. Q. Purpose of VDR and SVDR The purpose of a Voyage Data Recorder (VDR) and Simplified Voyage Data Recorder (S-VDR) is to maintain and store (in a secure and retrievable form) information concerning the position, movement, physical status, command and control of a vessel over the period leading upto and following an incident / casualty. The information contained in the VDR / S-VDR is to be retrieved and used during the subsequent investigation. For a vessel operating in shallow waters, cost of recovery of fixed VDR recording medium may not be very expensive. However, in case a vessel is lost in deep waters, the cost of recovery of the recording medium may be prohibitive and at times not feasible at all. In view of the foregoing, it has been decided that all Indian ships shall install the float-free variety of the VDR / S-VDR. However, if the shipowner has already installed the fixed type of VDR or it is not possible to install the float-free VDR meeting full requirements of the IMO Resolution, they shall ensure that an additional float-free arrangement may be made to retrieve the following information: Q. What is SSAS? The SSAS should be documented in the Ship Security Plan. The location of activation points should be specified in the plan and may form a part of the „Confidential‟ Section of the plan. It is advised that such information shall be known to the Master, Ship Security Officer and other ship personnel as may be decided by the Master and the SSO. The dedicated equipment used for transmission of Security of Security Alert should not be used for any other routine communication. communication. The system should have the main source of electrical power and a backup source, which may include emergency source or independent supply. However, However, an uninterruptible power supply (UPS) or such similar device may also be considered as an alternate source of power. All Indian Ship owners, owners, Company Company Security Officers, Officers, Masters and others concerned concerned may please note note that the SSAS SSAS test is to be carried out in the "LIVE" mode only. Q. How to test SSAS? The standard procedure for testing of Ship of Ship Security Alert System is as follows: 1. E-mail DG Communication centre the following information at least three hours in advance when requesting for a test : a) Name of the vessel and its present position b) Intended date and time (UTC) and IST of the test. 2. The DG Communication centre will acknowledge confirming the conduct of the test. It may be noted that SSAS tests with other ship/s may have already been scheduled at the proposed time, in which case, the DG Communication centre would advise the earliest suitable time for the conduct of the test. 3. The ship staff may then carry out the SSAS test as per schedule, first from Location 1. 4. The CSO/ Master shall confirm by phone whether the Alert has been received by DG Communication centre DG Communication Communication centre will then advise if all details provided in the alert are correct, or otherwise. 5. If all details received are correct, DG Communication centre will advise to reset the alert and then proceed to test from Location 2 6. When testing from Location 2, WAIT FOR about 30 minutes for alert to go to Level 3. 7. Call DG Communication centre to confirm whether alert Level 3 has been received. 8. DG Communication centre will confirm whether all is OK, or otherwise. If all is OK, DG Communication centre will advise the CSO/ Master to reset the system. 9. After resetting the system, the CSO/ Master to send an email to DG Communication centre stating that the "SSAS test has been completed and all subsequent alerts may be treated as true alerts." Request for compliance may be made immediately upon satisfactory completion of the test, and not after several days, 10. DG Communication centre will then revert compliance by email if tests were OK or advise further testing/ rectification, as required.

Steering gear incorporating the rapson slide principle are the most common in use on heavy duty applications. The rapson slide acting on either a fork tiller or the more common round arm. The tiller drives the rudder stock by means of a key or keys. The crosshead is free to slide along the circular arm of the tiller so that the straight line effort of the rams is applied to the angular moving tiller. Each set of two cylinders in line are connected by a strong steel girder usually called a "Joist" which stiffens the system and forms a "guide bar" for the crosshead guide slippers to slide along. The joist is often designed to incorporate the steering engine stops. An important consideration in all steering gears is the "wear down" of the rudder carrying bearing, this bearing takes all the weight of the rudder. Therefore there must be adequate clearance between between the bottom of the tiller and the crosshead bearing, so as the rudder bearing wears down in service the tiller and crosshead bearing do not touch, clearance when new can be 20 mm at bottom and 12 mm at top; top; the top clearance is a precaution to stop the tiller bumping up the steering rams in the unlikely event of the rudder lifting in heavy weather. Should the bottom of the tiller and the crosshead bearing touch, then the
weight of the rudder will be transferred from the rudder bearing to the steering rams with disastrous results such as leaking of working fluid from the cylinders and shearing of the ram

Q. Battery rooms Safeties A. a. Provision Provision for Ventilation Ventilation :- In Case of of Lead Acid batteries batteries during charging process Hydrogen Hydrogen & Oxygen Oxygen is evolved evolved / generated. The rate of evolution of these gases is high in c ase of overcharging. This H2 & O2 mixture is highly flammable over a wide range of 4% to 74% . Hence the possibility of explosion or fire in battery room is quite high . It is necessary that the accumulation of such gases is avoided & must be extracted from battery room so exhaust fan is provided . H2 being light extraction must be from the top of the room. * Fan should be fitted outside the the battery room. * Material of fan blade should be spark proof in case it may come in contact with the casing. * Outlet of the battery room duct (exh. fan) should be above accommodation level & it should be at the aft of the Engine room blower suction. Ventilation outlets are arranged at the top of the compartment as H is lighter than air b. Lighting :Lighting :- * All Lighting should be explosion proof. * Main Switch for Lighting should be outside the battery room * It should have 2 independent circuits. Each circuit cabin door is interlocked, If we open the cabin door the power is put 'OFF' & it is not possible to remove the key & same key is used for opening the fitting. Two keys for two circuits are not interchangeable. c. Distilled water Container :Container :- * Mostly PVC containers are used (Polystyrene or Polyvinyl chloride) * Glass Containers are not used as they may break & also electrolyte in distilled water may attack glass. * Steel Containers are not used DW attacks steel.all * If steel containers will will get loosened loosened & they they may produce spark. d. Use of Tools & Replacement of Batteries :Batteries :- * Tools should be insulated type so there will not be sparking & short circuiting if accidentally released from hand. * Aluminium tools are not used as it may produce sparking. * Electrical instruments should be intrinsically safe. * Before carrying out any maintenance it is necessary to check the atmosphere of the battery room
Q. Condition of Class A. A classification classification survey is a visual examination examination that normally normally consists consists of: • an overall examination of the ite ms for survey, • detailed checks of selected parts, • witnessing tests, measurements and trials where applicable. When a surveyor identifies corrosion, structural defects or damage to hull, machinery and/or any piece of its equipment which, in the opinion of the surveyor, affects the ship‟s class, remedial measures and/or appropriate recommendations/condition recommendations/conditionss of class are implemented before the ship continues in service. „Recommendation‟ „Recommendation‟ and „condition „condition of class‟ are are synonymous synonymous terms used used by IACS societies societies for requirements that specific measures, repairs, request for surveys etc., are to be carried out by the owner within a specified time period .
Q. GRT & NRT A. Various measures measures of the the cargo carrying capacity capacity or the volume volume of a ship: (1) Gross registered tonnage (GRT) is the total enclosed space of a ship expressed in registered tons of 100 cubic feet (2.832 cubic meters) each. GRT is a measure of the space available for cargo, crew, passengers, and stores, and is usually the basis for computing drydock charges. Also called gross tonnage.
(2) Under deck tonnage (UDT) is GRT less a ship's bridge, deck house, forecastle, and poop. (3) Net registered tonnage (NRT) is GRT less space occupied by the crew, engines, fuel, and navigation equipment. equipment. In general, GRT and NRT are in the ratio of 3:2 or, in other words, NRT is roughly equal to 60 percent of GRT. Also called net tonnage, it is usually the basis for computing harbour or port charges. (4) Dead weight tonnage (DWT) is the maximum weight (mass) of a ship when loaded up to its summer load line (see Plimsoll line) and is the sum of the weights of the cargo, crew, fuel, passengers, and stores. On average, DWT is about 60 percent of the GRT. (5) Displacement tonnage is the weight of water displaced by a ship computed on the basis that 35 cubic feet of salt water weigh one long ton (2240 pounds).
BALLAST WATER MANAGEMENT
The ballast water that is loaded by ships to stabilise them often contains organisms, e.g. small fishes, benthic organisms or plankton, or pathogenic bacteria, which are released into the environment when the ballast water is discharged. With continued growth of shipping traffic, the probability increases that such organisms survive the transport in ballast water. In this way, numerous invasive alien species have already established populations, e.g., in the North and Baltic Seas. In the Baltic Sea, the shipworm (teredo navalis) has damaged coastal defence structures, e.g. groynes made of local types of wood, by boring into the wood and destroying it. The damage caused by such invasive alien organisms is rarely expressed in figures, and its origin mostly is not traced back to the discharge of ballast water For quite a long time, this aspect of marine environmental protection lacked adequate international regulations. To address the situation in February 2004, the Ballast Water Convention was adopted during a diplomatic conference at IMO. From 2009, but not later than 2016, the Convention requires the establishment of a ballast water management system on board ships which will replace the uncontrolled ballast water uptake and discharge operations common until then. In future, ballast water has to be treated on board before being discharged into the marine environment, in compliance with the ballast water performance standard in Regulation D-2 of the Ballast Water Convention. Convention. The Ballast Water Convention will enter into force 12 months after the date on which not less than 30 states, the combined merchant fleets of which constitute not less than 35 percent of the gross tonnage of the world's merchant shipping, have deposited their instrument of ratification with IMO as the depositary (Article 18 of the Convention).
ISPS Declaration of Security 5 DECLARATION OF SECURITY 5.1 Contracting Governments Governments shall determine when a Declaration of Security is required by assessing the risk the ship/port interface or ship to ship activity poses to persons, property or the environment. 5.2 A ship can request completion completion of a Declaration of Security when: .1 the ship is operating at a higher security level than the port facility or another ship it is interfacing with; .2 there is an agreement on a Declaration of Security between Contracting Governments covering certain international voyages or specific ships on those voyages; .3 there has been a security threat or a security incident involving involving the ship or involving the port facility, as applicable; .4 the ship is at a port which is not required to have and implement an approved port facility security plan; or .5 the ship is conducting ship to ship activities with another ship not required to have and implement an approved ship security plan. 5.3 Requests for the completion of a Declaration of Security, under this section, shall be acknowledged by the applicable port facility or ship. 5.4 The Declaration of Security shall be completed by: .1 the master or the ship security officer on behalf of the ship(s); and, if appropriate,
.2 the port facility security officer or, if the Contracting Government determines determines otherwise, by any other body responsible for shore-side security, on behalf of the port facility. 5.5 The Declaration of Security shall address the security requirements that could be shared between a port facility and a ship (or between ships) and shall state the responsibility for each. 5.6 Contracting Governments shall specify, bearing in mind the provisions of regulation XI-2/9.2.3, the minimum period for which Declarations of Security shall be kept by the port facilities located within their territory. 5.7 Administrations shall specify, bearing in mind the provisions of regulation XI-2/9.2.3, the minimum period for which Declarations of Security shall be kept by ships entitled to fly their flag. Q.What Q.What is EEDI? Energy Efficiency Design Index (EEDI) is an attempt to measure how much CO2 a ship emits per unit of transport provided. provided . A formula producing an EEDI for each ship is developed. The current EEDI formula is outlined in MEPC.1/Circ.681, MEPC.1/Circ.681, Interim Guidelines on the Method of the Calculation of the Energy Efficiency Design Index for New Ships, 2009-08-17. Then an upper limit on EEDI is mandated for all new buildings. In most variants, this upper limit drops through time. The amendments to MARPOL Annex VI Regulations for the prevention of air pollution from ships, add a new chapter 4 to Annex VI on Regulations on energy efficiency for ships to make mandatory the Energy Efficiency Design Index (EEDI), for new ships, and the Ship Energy Efficiency Management Plan (SEEMP) (SEEMP) for all ships. ships. Other amendments to Annex VI add new definitions and the requirements for survey and certification, including the format for the International Energy Efficiency Certificate. The regulations apply to all ships of 400 gross tonnage and above and are expected to enter into force on 1 January 2013. However, under regulation 19, the Administration may waive the requirement for new ships of 400 gross tonnage and above from complying with the EEDI requirements. This waiver may not be applied to ships above 400 gross tonnage for which the building contract is placed four years after the entry into force date of chapter 4; the keel of which is laid or which is at a similar stage of construction four years and six months after the entry into force; the delivery of which is after six years and six months after the entry into force; or in cases of the major conversion of a new or existing ship, four years after the entry into force date. The EEDI is a non-prescriptive, non-prescriptive, performance-based mechanism that leaves the choice of technologies to use in a specific ship design to the industry. As long as the required energy-efficiency level is attained, ship designers and builders would be free to use the most cost-efficient solutions for the ship to comply with the regulations. The SEEMP establishes a mechanism for operators to improve the energy efficiency of ships. Promotion Promotion of technical co-operation The new chapter includes a regulation on Promotion Promotion of technical co- operation and transfer of technology relating to the improvement improvement of e nergy efficiency of ships, which requires Administrations, Administrations, in co-operation with IMO and other international bodies, to promote and provide, as appropriate, support directly or through IMO to States, especially developing States, that request technical assistance. It also requires the Administration of a Party to co-operate actively with other Parties, subject to its national laws, regulations and policies, to promote the development and transfer of technology and exchange of information to States, which request technical assistance, particularly developing States, in respect of the implementation of measures to fulfill the requirements of Chapter 4. Crane Safeties: 1. Upper and lower limit switch for hoisting 2. Jib max. and min. angle and rest position limit switch 3. Differential limit switch between luffing and hoisting (to keep a minimum distance between jib top and hook block, irrespective of jib angle) 4. Slewing limit switch (not for 360deg full slewing type) 5. Slack limit switch for hoisting rope (to protect the hoisting rope from irregular winding or slackening, hoisting device stops automatically by the limit switch) 6. Interlock switch for control handles (to prevent misoperation, misoperation, when starting and restarting the crane after the limit sw are acted) 7. Overload protector fm hydraulic parts ie relief valve (one each for hoisting n luffing and usually two for slewing, one for clockwise, second for anti clockwise) 8. Resistance thermometer sensor for oil cooler 9. Oveccurrent protector for induction motor
10. Low level switch for oil tank 11. Jib emergency limit switch (to stop the jib motion if due to sticky or smthin the luffing ckt is malfunctioning) Three Requirements for Dry Dock Stability is the most important requirement for getting a ship safely into a dry dock. The three important parameters which must be ensured before entering the dry dock are: 1) Adequate Initial G.M: When the ship touches the blocks, there is a reaction at the point of contact which raises the centre of gravity “G” and reduces reduces the metacentric metacentric height “G.M” so that adequate initial metacentric height is required to compensate the same. 2) Vessel to be Upright: While entering the dock the vessel needs to be upright which means there should be no port or starboard list when the ship touches the blocks, the point of contact will be outside the centre line of vessel, which may force the vessel to tip over. 3) Small or Moderate Trim Aft: The slight trim allows the accenting of stern and bow in tandem rather than simultaneously as it will reduce the load and pressure on hull and the keel of vessel. How to Rescue a Person from a Confined Space on a Ship? Following precautions precautions and procedures are to be followed for quick and effective rescue operation supposing a victim is to be rescued from an enclosed space. 1. General emergency to be announced through the ship‟s alarm. 2. A responsible officer to be made in charge of the operation. 3. Adequate man power to be present for the operation 4. Two trained persons to be ready with SCBA and PPE. 5. All prior checks to be carried out on SCBA used in the operation. 6. Life line to be used by the entry person. 7.
