1 Service Manual aquata Immersion Suits Ship Check 01/08 Nr.03

2 Service Manual aquata Immersion Suits 01/08 1. Check-up The actions of the check-up are wrapped-up in the form on the last page. A monthly check-up of the suits is not necessary if the suits are unused and in the original package. We recommend checking the suits every 18 months, whereas regulation only requires a 36 months check-up. Especially if there are reasonable worries that parts of the suit might be stolen or if they are stored under inappropriate conditions, an 18 months check-up makes sense. The following actions are required: actions c) Visual inspection of the suit. Tidiness (Oil/dirt) defective sewing, loose parts, as leg tapes or back pillow, come off pockets or belt holder, broken shoes, strongly used gloves,missing or defective reflex tapes. a) Fill out the form with the serial number of the suit, model description, etc. b) Open the nylon bag 4. Control the last on board check, fill in necessary 5. Date with stamp and signature 1.Check if the sack is dirty or damaged and compare suit Number on sack with suitnumber 6. Open bag, lay suit flat on clean table. Check suit if dirty or has visible damage. Defect seams, detached parts 2. The suitnumber is also inside windflap, control it with the bag number and write down the date of check. If the hologram does not exist put Hologram in suit and on bag Page 2

3 Service Manual aquata Immersion Suits 01/08 d) List up missing parts like carbine snaps, belts, lights, whistle, etc. e) Check the metal zipper (if applicable). If the metal zipper is corroded (teeth become green), use silicone spray to make it work again. Then apply some wax (aquata zipwax). 10. Check gloves, seams, dirts, damages 7. Check helicopter belt 11. Check shoesoles if fixed to suit and not broken 8. check if buddy line exist and has useable carbine hook 12. check legfastener tapes if correctly glued. Pull horizontally 9. check if whistle and Pull triangle in place Page 3

4 Service Manual aquata Immersion Suits 01/ Suits without backpillow (Model V20 OP ) must be used with separate lifejacket. This means light is fixed to lifejacket. Suits with backpillow must have an own Solas approved light. Different light can be used like Oceansafety, Danimanat or aquata light AQ1, wich can be fixed on special holder. The light must be changed after 5 years. 15. SEY rubberzipper from outside. 16. SEY rubberzipper from inside. 14. Aquata suits using whether the meal zipper or the SEY rubberzipper. The metal zipper tend to be corrosive, so during check It is necessary to pull the slider different times up and down. To make the slider easier use aquata waystick all over the metal teeth und pull the slider 3 or 4 times up and down, until it runs easily. If the slider is blocked try to unblock it carefully, pulling it down with some silicone spray. Notice!! If the teeth cannot closed anymore completely, the zipper must be changed in an approved servicestation with original aquata parts only. The SEY rubberzipper need no wax but must have other care. The end of zipper inside must have a glue stop. Otherwise the slider can damage the neoprene. If the gluestop is lost put in some epoxy glue at this position to make a new sliderstop. It is recommended to put Siliconefat in the rubberlips and especially at the bottom of the zip where normally the slider rests. Some zippers of this type have very weak lips. So if the slider stay there during storage the lips may widen a bit so that small amount of water may leak in there. This is why we recommend to press in some grease between the lips at this position and do not slide down now the slider anymore so deep to recover the bend rubberlips. Page 4

5 Service Manual aquata Immersion Suits 01/ Turn the suit and examine the position where the zipperpart is fixed to the suit. Both parts should be still together and do not show a damage, as this is a stress point. 18. Aquata delivers special test equipment for checking the survivalsuits on board. Wax the metal zipper careful with aquata zipwax and the SEY zip with some silicone or vaseline fat especially between the lips at the bottom end of zipper. Put the testhead in the neckarea and close the zipper carefully. The wide strap is pulled around the neck outside of the suit and tight fasted. Now slowly fill the suit with air and watch the meter. If the instrument shows millibar spray soap water on the suit and examine if any bubbles arise, as there might be any leakages. By the special construction of the SEY zipper very small bubbles may arise from the zipper, as the rubberlips close only complete if the water is pressed from outside. If heavier bubbles blow out the suit must be send to a aquata servicestation for repair or zipperchange. After testing the suit must be dried in a warm room but not under heavy sunshine, or in the near of heaters or UV supplying machines. Depending on the zipper we recommend different way of packing. For the metal zipper the suit is flat on a table with frontside to the top. Rolling starts from legs. Hands are crossed over the breast, the helicopterbelt is open and also the metal zipper is open, as after a time of storage it is more difficult to open and close it. The suit with SEY zip is on the table with backside to top, rolling start from the legs, here the zipper is closed. Put the suits in the carrybag and close the string. Make an easy to open closure of string, do not!! make any knots. If faster exist pull the string and lock with fastener. Write down the date of the maintenance and fill out the corresponding form. Write the next maintenance date into the suit (only model numbers greater than 65,000) as well as on the carrying bag (Date Test (Month/Year) or Date NC (Month/Year)). If there is only space for one date, the short form NC or Test is required. If the suit show any damages, send it to next aquata recommended servicestation for repair. Page 5

One copy remains at the service centre which carried out the maintenance. One copy is sent to the manufacturer on a monthly basis. Page 6

10 INTERNATIONAL MARITIME ORGANIZATION 4 ALBERT EMBANKMENT LONDON SE1 7SR Telephone: Fax: IMO E Ref. T4/3.01 MSC/Circ May 2004 GUIDELINES FOR PERIODIC TESTING OF IMMERSION SUIT AND ANTI-EXPOSURE SUIT SEAMS AND CLOSURES 1 The Maritime Safety Committee, at its seventy-eighth session (12 to 21 May 2004), recognizing that shipboard inspections of immersion suits and anti-exposure suits carried out in accordance with SOLAS regulation III/20.7 and MSC/Circ.1047 may not be adequate to detect deterioration of seams and closures of the suits due to adhesive ageing, and having considered the recommendation made by the Sub- Committee on Ship Design and Equipment at its forty-sixth session, approved the Guidelines for periodic testing of immersion suit and anti-exposure suit seams and closures, as set out in the annex. 2 Member Governments are invited to bring the annexed Guidelines to the attention of all parties concerned. I:\CIRC\MSC\1114.DOC *** MSC/Circ.1114 ANNEX GUIDELINES FOR PERIODIC TESTING OF IMMERSION SUIT AND ANTI-EXPOSURE SUIT SEAMS AND CLOSURES 1 Research performed by several Member Governments has demonstrated that the seams and closures of immersion suits and anti-exposure suits experience deterioration over time. The rate and severity of deterioration may vary widely, depending upon the specific components and procedures employed in the manufacture of the suit and the conditions under which the suit is stored. However, even under ideal conditions, the materials and adhesives used have a finite service life and will inevitably experience a reduction in strength and/or loss of watertightness with age. 2 The Guidelines for monthly shipboard inspection of immersion suits and anti-exposure suits (MSC/Circ.1047) are very helpful in identifying obvious problems with a suit, but do not adequately address deterioration of seams and closures (zippers, etc.) which may not be readily apparent by visual inspection. Such deterioration can be detected by pressurization of the suit with air, and testing of the seams and closures for leaks with a soapy water solution.

11 3 To ensure the maintenance of adequate strength and watertightness of seams and closures of immersion suits and anti-exposure suits with age, it is recommended that each suit be subjected to an air pressure test such as the following, at intervals not exceeding three years, or more frequently for suits over ten years of age:.1 A suitable head piece, fitted with a means to inject air into the suit, should be inserted into the face orifice of the suit and secured so as to minimize leakage around the face seal. A low-pressure monitoring device, either integral to the fitting for air injection or as a separate device, should also be inserted. If the suit is fitted with detachable gloves and/or boots, the wrists and/or cuffs should be sealed by inserting a short length of suitable diameter plastic pipe and securing the gloves and/or boots with suitable wire ties or hose clamps. The zipper should be fully zipped, and any face flap closed. The suit should then be inflated to a pressure of 0.7 to 1.4 kpa (0.1 to 0.2 psi). If an auxiliary inflatable means of buoyancy is provided, it should be inflated through the oral valve to a pressure of 0.7 kpa (0.1 psi) or until firm to the touch..2 Each seam and closure of the suit - and each seam, oral tube and attachment points and joint or valve of any auxiliary inflatable means of buoyancy - should then be covered with a soapy water solution containing enough soap to produce bubbles (if leakage is noted at a foot valve to the extent that air pressure cannot be maintained, the valves should be sealed for the test)..3 If leaks are revealed by the propagation of bubbles at seams or closures, the leaking areas should be marked and, after cleaning the suit thoroughly with fresh water and drying it, repaired in accordance with the suit manufacturer's recommendations. I:\CIRC\MSC\1114.DOC MSC/Circ.1114 ANNEX Page 2 It is recommended that the air pressure test be performed at a suitable shore-based facility equipped to make any necessary repairs in accordance with the manufacturer's recommendations. In view of the wide variety of materials and adhesives used in immersion suits and anti-exposure suits, it is strongly recommended that any repairs to a suit be carried out by a facility which has access to the original manufacturer's recommended servicing instructions, parts and adhesives, and suitably trained personnel. The air pressure test may be carried out on board ship if suitable equipment is available.
