3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1 loose fittings
securing devices not welded to the hull
3.2 fixed fittings
securing devices welded to the hull
3.3 securing fittings
securing devices used between containers and between a container and the deck, hatch cover, or bilge,to prevent the container from longitudinal, transverse, or vertical movements relative to the hull during transportation
3.4 lashing fittings
securing devices used to lash a container to a hatch cover or deck
3.5 buttress fittings
securing devices used to eliminate the clearance between a container and a longitudinal bulkhead and transfer any transverse forces to the longitudinal bulkhead
4 Installation, inspection and maintenance
4.1 Securing devices
4.1.1 Types
Securing devices can be divided into three types, namely securing fittings, lashing fittings and buttress fittings, each type divided into fixed fittings and loose fittings.
4.3.2.2.3 Intermediate inspection
A securing device, whose lashing effect may be loose under stress during use, shall be examined and, if necessary, immediately adjusted by tightening or relashing. Inspection shall be carried out after a container is loaded and secured on-board in a low temperature, or when the ship enters a hot environment. Visual inspection of a securing device shall be carried out during daily use, to ensure its good performance.
4.3.2.2.4 Special inspection
Comprehensive inspection shall be carried out for all securing devices to ensure galvanized and paint surfaces are properly anti-corrosive, without any breakage, serious wear, deformation, cracks or severe rust. For updated securing devices, the related certificates shall be obtained.
4.4.1 Maintenance of fixed fittings
4.4.1.1 Welds attached to the hull structure shall be inspected. Preferably, defects and cracks should be rectified by slotting or other methods. If necessary, welding repairs shall be made with an electrode matching the original materials. Before welding, an area out 20 mm all around the position to be welded shall have rust, greasy dirt and moisture removed and be polished until the metallic luster is exposed.In case of welding defects such as pores and cracks, they shall be polished until any such defects are eliminated before re-welding.
