2.3.1.7 Cargo hatch cover wedges, clamps and quick acting cleats. All hatch cover wedges, clamps and quick acting cleats (see Figure 2.4) should all be present, well maintained and greased, properly adjusted with good washers and resilient packing rings, and free of damage and deformation. The rubber washers of cleats should be sound, flexible, not dried out and free from paint. If different tensions are applied when closing cleats, it is an indication that the hatch panels may be misaligned. 2.3.1.8 Hatch cover landing pads. Hatch cover landing pads should have minimal wear to avoid over-compression of the sealings. 2.3.1.9 Hatch covers and coamings. Hatch covers and coamings should be free from holes, cracks, unsealed penetrations or significant damage (see Figure 2.5). Sampling points (if any) are to be clearly marked, with caps in place and operational. The importance of ensuring the proper working condition of hatch covers to prevent water or condensation damage cannot be overstated. Any repairs to hatch covers and coamings should be conducted in accordance with the manufacturer’s instructions. 2.3.1.10 Hatch cover hydraulics. Hatch cover hydraulics should be clear of corrosion, and free of damage, deformation and leakage. They should be fully operational and adjusted. Special attention should be paid to the condition of hatch cover control hydraulic systems (e.g. pipes, valves, control boxes, etc.). The systems should be in a sound and leak-tight condition to prevent any spillage or spray of oil into the cargo hold and possibly damaging any cargo within. 2.3.1.11 Drainage channels. All drainage channels should be free from previous cargo residue, rust scale, significant corrosion or damage. 2.3.1.12 Vents. Fitted vents should be clear of corrosion and free of damage and deformation. The hatch lids are to be in good condition and are able to move freely. 2.3.1.13 Mechanical ventilator flaps and ventilation hatches. Ventilator flaps and hatches should be in good working condition so they can be properly sealed and secured when closed as seen in Figures 2.6 and 2.7. 2.3.1.14 Ballast, top side and other tanks. The double bottom ballast tanks, hopper tanks, side tanks and top-side tanks (if any) should be hydrostatically pressed up prior to loading to ascertain their watertight integrity as seen in Figure 2.8. During the pressure test, attention should be given to any water entering into the bilge wells as this may indicate damaged bilge well plating or bilge piping. If pressure testing is unfeasible at berth, the internals of the cargo hold, including piping, should be checked for signs of water ingress. American Club: Transport Guidance for Steel Cargoes 22 2.3.1.15 Bilge suctions and tank top openings. These items, including the non-return valve function of the bilge wells, should be thoroughly examined, tested and proved fully operational. Bilge wells should be opened, their cleanliness ascertained and the strainer plate should be covered over with burlap. Any openings to the tank top should be examined to ascertain their watertight integrity and should be properly secured. 2.3.1.16 Sounding pipes and other pipes passing through the cargo holds. Piping systems should be examined and ascertained to be clear of any debris. Any pipes within the holds, including ballast pipes, sounding pipes and tank air pipes should also be closely examined to ensure they are free from holes, significant rust scale and properly protected. In addition, sounding pipe closures should be checked to ensure that they are watertight. 2.3.1.17 Shipboard cranes. Shipboard cranes to be engaged in cargo operations should be in a satisfactory structural condition with the safe working load clearly marked. The cranes should be tested/examined to ensure crane wires, hooks and sheaves are in a satisfactory condition and safety devices are fully operational. 2.3.1.18 Manholes. Manhole gaskets should be clean and free from debris and dirt which can cause leaks when manhole covers are refitted. In addition, all manhole covers should be checked to ensure they are tightened evenly. 2.3.1.19 Tank tops. Tank tops should be checked for structural integrity that may be due to simple wear and tear or cracks in the welds. Also refer to Sections 5.3.3 and 5.3.4 for comments on requiring tank top strength and point loading. 2.3.2 Maintaining reports on the condition of the hatch covers. The owner should maintain up to date written reports on the condition of the hatch cover arrangement onboard that include details of: (1) scheduled maintenance and tests conducted as part of the vessel’s planned maintenance system and any additional unscheduled maintenance and repairs performed; (2) inspection and testing of the operability of the hatch cover arrangements, as specified in tải về 1.97 Mb.
