PART 1 DESCRIPTION

1.1 DESCRIPTION

The lifeboats are stored on the boat davits on both sides of the ship. In case of emergency, the crew can board the lifeboat and escaped with the lifeboat directly from its stowage position.

The launching appliance consists of a boat davit (davit arm, frame, platform, falls, suspension block, and gripes/lashing device) and a boat winch (reduction gears, hand brake and centrifugal brake).Swinging out and lowering of the lifeboat can be controlled both from the inside of the lifeboat and at the ship’s deck. The lowering speed of the lifeboat can be controlled by operating the remote control wire inside the lifeboat or by operating the remote control lever on the ship’s deck. Moreover, it is possible to suspend the lowering operation of the lifeboat at any height. Recovery of the lifeboat is performed by operating the boat winch with the push-button switch box. When the davit arm reaches a prescribed position, the boat winch is automatically stopped by the limit switch. After the activation of the limit switch, the boat winch is operated manually to wind upthe lifeboat to its stowage position. The boat winch is provided with a safety device to prevent there verse operation of the manual handle.

The lifeboat is equipped with on-load/off-load release gear which complies with the requirements of the IMO Life-Saving Appliance (LSA) Code. To avoid possible injury or death, read this manual carefully before using the boat davit, the boat winch, and the on-load/off-load release gear.

The pivot davit system allows:

- Launching of the boat from stowed position up to the water level.

Boat with full complement of persons.

- Hoisting of the boat including operation crew of 3 persons (lifeboat modus)

- Launching/hoisting of the boat including crew of 6 persons (life/rescue boat modus)

Davit system is designed in that way to allow launching of the boat in following

Ship conditions:

List ± 20° (30° for tankers)

Trim ± 10°

Lowering hoisting speeds are determinate as follows:

Gravity lowering speed according to SOLAS formula

V=0,4+(0,02xH) m/s, max. 1,0 m/s V= gravity lowering speed (m/s)

H= height from davit head to the waterline at the lightest seagoing condition (m)

Hoisting speed

Lifeboats min 5 m/min

Life/rescue boat min 18 m/min

1.2 RULES AND REGULATIONS

As part of lifesaving equipment davit is designed, produce and tested in accordance to following Rules and regulation:

- SOLAS 1974, with latest amendments

- SOLAS 2001 Consolidated Edition 2004

PART 2 OPERATION

2.1 GENERAL DESCRIPTION

The system provides for the crew to evacuate a vessel in a minimum period of time and to be afloat in a totally enclose craft and fully protected from the elements. The lowering of the boat is controlled by a winch with a handbrake of the ‘dead man’ type and a centrifugal brake which imposes a predetermined speed of lowering.

. SAFETY SUMMARY

During the working at davit (on-board) general safety precautions to be considered as follows:

- Inform Officer in duty when starting and finishing work at davit

- Isolate or disconnect the electrical supply to the davit/winch before commencing

With inspection / maintenance programme

- When re-reeving or overhauling winch or davit the safety pendants must be attached to the davit and boat. Davit arm have to be fixed with locking bar.

ENSURE THAT BOTH PENDANTS ARE CORRECTLY ATTACHED TO THE

PENDANT LUG ON THE FORWARD/AFT SIDE OF THE BOAT LIFTING HOOKS.

ON NO ACCOUNT TRY TO ATTACH THE PENDANT SHACKLE TO ANY

OTHER PART OF THE FALLS OR BOAT.

- Do not operate davit/winch with inserted crank handle of the winch.

- Always wear gloves when handling wire rope or remote control wire rope to avoid injury to hands.

- To avoid damages on equipment, grease and oil must be kept free of dirt and other contaminants.

- During the work on the davit use always hard hat.

- Operating with davits follow Launching procedure mounted on-board (on davit position).

- Use always Instruction Manual (available on board).

Eventual other safety measurements should be take in according to on-board s

Finally release the painter to get out of the vessel.

For operation follow the lifeboat operation manual !

Ensure boat is level before hand winching into fully stowed position, i.e. the craft coming evenly up against the boat chocks.

Misalignment CANNOT be corrected by continuing to crank the winch. This is dangerous as it overloads the boat by over-straining the fall wires, then one end of the boat contacts before the other.

Misalignment should be corrected by using the falls adjustment turnbuckles in the prescribed manner before final stowage is commenced.

2.4.2 RECOVERY OPERATION (HOIST SURVIVAL CRAFT)

PART 3 MAINTENANCE & SERVICE

3.1 SAFETY REQUIREMENTS

1. Isolate or disconnect the electrical supply to the davit/winch before commencing with inspection/maintenance programme.

2. When re-reeving or overhauling winch or davits the safety pendants must be attached to davit and boat.**

3. Always wear gloves when handling wire rope to avoid injury to hands from any broken strands within wire rope.

4. Do not allow the wire rope to be soaked or washed in a container of cleaning solvent (see details) as this may damage the fibre core of the rope.

5. All brake linings must be kept in good condition and free from grease. Grease on the linings will cause slippage and a serious accident may result.

6. To avoid damage to equipment and bearings, grease and oil must be kept free of dirt and other contaminants.

7. Do not leave loose objects or let objects fall into winch gear case as they can cause sever damage to the equipment.

** ENSURE THAT BOTH PENDANTS ARE CORRECTLY ATTACHED

TO THE PENDANT LUG ON THE FORWARD SIDE OF THE MAIN

LIFTING HOOK.

ON NO ACCOUNT TRY TO ATTACH THE PENDANT SHACKLE TO

ANY OTHER PART OF THE FALLS OR BOAT.

WHEN GRIPES (LASHINGS) ARE RELEASED THERE IS A HIGH

RISK THAT THEY COULD BE CAUGHT AROUND BOLLARDS OR

JAMMED BETWEEN ROPE GUIDES ON THE LIFEBOAT

BEFORE THE BOAT IS FULLY TURNED OUT AND LOWERING

COMMENCES CREW MUST CHECK AND CONFIRM THEY ARE

COMPLETELY CLEAR OF ALL POTENTIAL OBSTRUCTIONS

LUBRICATION

Gravity davits are mechanical devices. Like other machines if they are to retain their efficiency they must be regularly lubricated and inspected. All bearings/sheaves on the davit are maintenance free. The winch gear case oil level should be frequently checked.

For greasing of winch refer to Winch maintenance .

Other points calling for special attention are mentioned later.

Suitable grades of recommended lubricants are listed later.

PAINTING

Careless painting is the most frequent source of trouble with gravity davits.

WHEN PAINTING IT IS ESSENTIAL TO ENSURE THAT NO PAINT IS

APPLIED TO LUBRICATING POINTS, OR TO BEARINGS OR ANY MOVING

PARTS IN SUCH A WAY AS TO IMPEDE THEIR FREE MOVEMENT.

3.2.2 FALLS & WIRES

1. Falls are reeved as shown on Drawing Wiring Diagram. Turnbuckles are provided for levelling of falls should they stretch unevenly or coil incorrectly.

2. Falls and wires must be inspected periodically to check condition. They will give longer service if changed end to end before showing signs of wear.

3. Rope lubricant should be applied regularly to ropes in quantities sufficient to produce a thin, even adherent coating, which will remain flexible and fully protective over the full range of temperatures likely to be encountered in service.

See Part 7 for lubricant details.

4. Falls should be cleaned of foreign matter and corrosion using a

‘trichloroethylene’ based solvent and a cleaning swab. Do not allow the falls to be soaked in the solvent as this may damage the fibre core of the rope. Allow to dry thoroughly before applying rope lubricant.

5. Falls must be neatly coiled on the winch barrel. Turns must not override one another, otherwise the boat will come home unevenly.

6. When renewing falls the correct size, construction, breaking strain and length should be ascertained.

Wire ropes should be changed in the following cases:

.1 break of elemental wire was observed;

.2 7% reduction of nominal diameter was observed;

.3 kink or looseness of ply was observed; or

.4 erosion / corrosion was observed.

3.2.3 WINCH MAINTENANCE INSTRUCTIONS

See separately winch operation & maintenance manual

PART 4 SERVICE ACTIVITIES

4.1. ANNUAL (ONE YEAR SERVICE) AND FIVE YEAR SERVICE

In this chapter the required maintenance (service) for one year and five year will be described.

It is to be executed by the FASSMER authorised service personal.

Procedure is in accordance with IMO MSC/Circ.

For Fassmer pivot davit system it is essential to have any repair performed by skilled labour only.

No Name spare parts will be dangerous also in that way that a proper function of the davit my not be ensured.

4.2. ONE YEAR SERVICE

1. Davit structure in particular with regard to corrosion and deformations.

2. Wire rope and wire rope sheaves should be checked against possible damages such as kinks and corrosion.

Wire rope sheaves must be turning freely and the grooves should seat the rope properly.

If any damage will be finding on wire ropes sheaves the damaged sheaves should be exchange.

Following this requirement also should be checked remote control wire rope including remote control wire rope sheaves. In fact that remote control wire rope sheaves are from plastic material should be checked against damages. If any sheave will be damaged should be exchange against new one. Check connection of remote control wire and PA wire.

3. Lubrication of wire rope, wire ropes sheaves and moving davit parts.

The davit has been provided with maintenance free, pre-lubricated bushes, running on stainless steel shafts. Special maintenance of these turning parts is not necessary.

Wire rope required re-lubrication and if necessary prior cleaning. Re-lubrication should employ grease that is compatible with the manufacturer’s lubricant.

The coating must be such as not to impair the visual inspection of the wire rope surface.

Check that swivel eye on lower block has been greased. If necessary greased the same.

Remote control wire rope is from stainless steel and should not be lubricated.

4. Oil in winches gear boxes should be changed.

Before filling the gearbox with new oil , it should be thoroughly cleaned with scouring oil.

Quantity of oil is mentioned in each Winch Instruction Manual available on board.

5. Open and inspect brake mechanism of the winch. In case that is necessary replace brake pads.

6. Functioning of limit switches should be checked.

7. Function of remote control should be checked.

NOTE:

Pos. 6 and 7 are checked during functional test of complete davit system.

8. Dynamic winch brake test

Annual operational testing should be done by lowering the empty boat.

When the boat has reached its maximum lowering speed and before the boat enters the water, the brake should be abruptly applied.

Please note that this annual test is performed with empty boat (boat with equipment but without load of boat persons).

4.3. FIVE YEAR SERVICE

Only FASSMER authorized personal are legitimate for the 5 year service.

For Service and spare parts please contact the Fassmer Service Office, Service Hotline

Phone +49 (0) 1805 03 54 85 or Internet www.fassmer.de/

During five year service all activities (except Dynamic winch brake test) from one year service should be applied.

In addition following activities should be done:

1. Wire rope

Wire rope must be renewed (new wire rope have to be installed) if not done before.

2. Dynamic winch brake test

Five-yearly operational testing should be done by lowering the boat loaded to a proof load of 1.1 times the maximum working load of the davit.

When the boat has reached its maximum lowering speed and before the boat enters the water, the brake should be abruptly applied.

To estimated required test loads please follow TESTING LOAD ESTIMATION procedure.

GUIDELINES FOR PERIODIC SERVICING AND MAINTENANCE OF LIFEBOATS,

LAUNCHING APPLIANCES AND ON-LOAD RELEASE GEAR.

As information above mentioned document is attached to this Manual.

In this document are specified required inspection and service activities and generally divided in following main groups:

- Weekly and monthly inspection and routine maintenance performed from side of

Ship crew under supervision of senior ship’s officer.

- Annually and five years inspection, servicing and repair which should be conducted by

Manufacturer’s representative.

In this manual we will concentrate us to Annually and Five years’ activities.

In other hand we are expecting that FASSMER authorized personal will take part during commissioning and testing on board of FASSMER equipment therefore also this activity will be described in this Manual.

Following above mentioned IMO Document after each Annual and Five Year Service should be issued Service Reports and Certificate of Serviceability.

Those documents will be also described in this Manual.

Essential is to mentioned that during all Service activities should be also used Davit

PART 6 FAULT FINDING

LOGICAL TRACING OF FAULTS

6.1 BOAT DOES NOT LOWER WHEN BRAKE LEVER IS LIFTED

1. Check that arm locking bars are not in place and preventing boat lowering.

2. If winch is still reluctant to run out, fit locking bars and check free running of winch in lowering direction. Normally, a pull of approximately 100 kgs is sufficient when applied to the falls with brake lever lifted.

3. If winch is free running, davit must be stuck fast with paint on pivot or sheave pins and sheave housings.

These must be free of paint and greased.

4. If davits have sustained any damage by weather, cargo handling etc., misalignment of various points may be the cause. In this case, davit manufacturer should be contacted.

6.2 BOAT LOWERS TOO QUICKLY

1. Dismantle centrifugal brake housing and check that there is no grease or oil on winch brake shoes.

Clean if necessary or renew. (See Maintenance Section for details).

2. Check that brake is not worn down to shoe material. Renew if necessary.

6.3 BOAT LOWERS TOO SLOWLY

1. Check free running sheaves and winch.

6.4 BRAKE OR CLUTCH FAILS TO HOLD BOAT

To check clutch: see winch manual

6.5 WINCH NOT FREE RUNNING

1. Check that oil in gear case is of correct viscosity and level.

2. Check gear teeth for breakages and gear case for foreign matter.

3. Check bearings for collapse and bearings and shafts for rust and corrosion.

(This should not occur with correct periodic maintenance).

6.6 WINCH WILL NOT HOIST BOAT

1. Check that there is an electrical supply to the motor.

2. Check that the crank handle has not been left in position on the winch.

NOTE: The crank handle protection switch lever when moved out of way for crank handle insertion, will ‘CUT OFF’ supply to motor.

3. Check that the hoist limit switches on winch axle are not jammed in the ‘OFF’ position and are free to operate.

4. Check that the brake lever is in the ‘FULLY ON’ position. If it is not ‘FULLY

ON’ it will cause the brake to slip. If it is ‘FULLY ON’ and the electrical supply is available to motor, then the brake is contaminated with oil or grease and is slipping. Renew the brake lining.

After survival craft davit systems has been installed, testing and commissioning has to be carried out.

1.1 PRE-COMMISSIONING CHECK

01. Check gear case of winch has correct level of oil to upper drain plug level.

02. Check sheaves greased if not free maintenance.

04. Check manual operation of hoist limit switches.

06. Check wire rope falls are correctly reeved through sheaves and wound evenly on winch drums.

07. Check wire rope socket fixing at winch barrels.

08. Check remote control wire reeving is correct and clamp bolt tightened up.

09. Ensure handbrake is in full on position.

10. Check suspension chain end links are correctly fitted with survival craft release hooks.

11. Check electric supply is available to winch and connected correctly.

12. Ensure that required test weights (sandbags or water bags) are available. Sandbags or similar weights must be available to take place of persons during tests. Weights to be put on board at embarkation level, evenly distributed.

1.3 TESTING ON BOARD

Testing has to be carried out in presence of attending Surveyors, who will probably also wish to witness other commissioning / testing activities.

All davits and winches are already tested at works but onboard test must be carried out after installation.

Required is lowering test of fully loaded boat weight plus 10% overload.

On board test is specified by IMO Resolution MSC.81(70) Part 2 Section 6.

After installation of davits and boat the System has to be approved by a surveyor from the appropriate authority.

All davits and winches are already tested at works but onboard test must be carried out after installation.

LSA require lowering test of fully laden boat weight plus 10% overload.

TEST LOADS

Surveyors will state exact loads they require but, in order to have sandbags etc.

available, we give the following information:

Boat CLR-T 6,4

Fully Loaded weight (53Persons) xxx kg

Plus 10% xxx kg xxx kg

Less boat weight xxx kg xxx kg

Therefore xxxx kg of sandbag/water bag weight is required for lowering test

Check that test weights are properly fastened in the boat.

It is recommended the use of solid ballast.

TEST

Tests should be made to ensure that all survival craft can be re-stowed from the embarkation position safely and with facility when loaded with the required equipment and that when so loaded the craft can, when released, be lowered by gravity into the water against the frictional resistance of the winch, falls, blocks and other associated gear.

Each set of davits or launching appliance and any associated winches and their brakes should be capable of lowering the survival craft from the embarkation deck into the water loaded with the required equipment and a distributed weight equal to the full number of persons which it is deemed fit to accommodate plus 10 per cent of the working load. Winch brakes exposed to the weather shall be capable of withstanding the foregoing test with the braking surface wetted. For the purpose of the tests the weight of a person should be taken to be 75 kg (165 pounds).”

1.4 COMMISSIONING/TESTING

01. Establish that Pre-Commissioning Checks have been completed satisfactorily.

02. Load weights into survival craft and distribute them evenly in craft.

03. Ensure that hanging off pendants are not attached to secondary lift points on hooks.

04. Rotate brake lever allowing survival craft to lower at a speed automatically controlled by centrifugal brakes.

05. When requested/instructed by surveyor, operator releases brake lever and allows action of falling brake weight to bring winch to a halt.

06. Repeat as instructed by surveyor.

07. Hoist to embarkation level. Be prepared to stop winch on emergency stop button if limit switches do not cut out.

08. Lower survival craft again. This time for surveyor to check lowering speed.

09. Hoist to deck level and remove test weights.

10. Check hoist limit switches cut off approximately 150mm from stowed position by carefully hoisting boat towards stowed position. Be prepared to stop winch on emergency stop button if limit switches do not cut out.

11. Lower survival craft to say 1 metre below stowed position and hoist a little to prove all limit switches are closed.

12.With crank handle inserted and personnel well clear of it, press hoist push button to check protection switch has cut off power supply to winch.

14. Remove crank handle and carefully hoist craft to embarkation level.

15. Check operation of remote control from within craft. Crew member pulls down on remote control wire in craft, which will rotate brake lever and allow craft to lower.

Maintaining pull on wire will allow craft to lower until pull is released. Craft will come to stop as brake level drops to put holding brake on.

To continue lowering, remote control wire is pulled again.

16. Hoist craft back up to hoist limit switch cut off position

Complete stowage of craft by operating winch crank handle

18. Remove crank handle and stow it on winch.. Switch off electric supply.

08. Position holder on arm and frame of winch remote control. Reeve the remote system as shown on drawing: ARR. OF WINCH REMOTE CONTROL

09. With boat suspended from davit arm head horns, offer up boat chocks and weld in position as shown on drawing: BOAT CHOCK FWD&AFT

10. Mounting davit arm stop and boat sea lashing ropes. Adjust the length by using the wire rope clams if necessary.

IF USING CLAMPS ON LASHING ROPES (∅14-16mm)

CLAMPING BRACKET ON FREE ROPE END

LOOSE END BOUNDING

TIGHTENING TORQUE ∅14mm=36 Nm

∅16mm=54 Nm

11. Check function of control wire lowering. A steady pull on the end of the control wire will initially pull brake lever round and release holding clutch on winch. Maintaining a pull will lower the boat and releasing pull will stop winch as weighted brake lever returns brake to holding position.

12. Connect hanging-off pendants. These are used only when work is being carried out on the boat hooks. When working on the hooks the pendants should be attached to the eye on outside of suspension hooks on boat. The boat weight is then transferred to the pendants by tightening the turnbuckles to take weight off wire ropes to winch. After completion of work, remove pendants from suspension lugs and hang on stowage bars on arm.

13. Check all oil levels and grease all ropes.
