Correct stacking of OCTG is vital in the interests of avoiding damage to, and distortion of pipe whilst in storage. General hints on good practice are pinned to the Info Board.
Pipe stacked correctly pin to pin, box to box, separated by 4 rows of timber dunnage and wedged
Correct stacking in desert location with mobile crane rather than fork-lift. Cranes are required where the yard surface is non-compacted or uneven or where levels vary across the yard.
Correct clearance under stack provided by concrete bearers with timber dunnage under the stack.
Correct alignment of box ends. Casing with bumper rings installed to prevent metal-to-metal contact
Fork lifting is ideal for secure handling of casing in a stock-yard with good flat concrete or tarmaced surface.
Fork-lift with 20ft / 6 m spread at the forks
It is always important to load to vessel hold securely and safely, both to avoid movement in hold and damage to cargo.
Casing in hold prior to discharge
Discharge to truck on quay
Setting up stack for temporary storage at port
Protectors should always be checked for tightness when the pipe stack is made up. This prevents the ingress of rainwater and dust.
Loading to trailer. The load must be kept below the top of the head-board.
Pre-slinging of casing into 10-joint bundles
Box end protectors
Closed-end liftable protectors with weep-hole to prevent the build-up of pressure inside the casing joint due to temperature variation.
Pin end protectors
Alternative method of providing bumper rings using heavy gauge polyproylene rope offcuts secured by nylon cable ties. Especially useful for protecting exposed box ends of flush-joint casing
General cargo hooks are unsuitable to pick-up casing with open-ended or closed-ended liftable protectors
General cargo hook
Flat-faced nylon-lined pipe hook should always be used for handling single joints of casing. Bundles should always be slung.
Flat-faced pipe hooks
Loading and discharging of containers, particularly conventional end-opening containers, needs to be done with extreme care, both to avoid damage to the cargo and to avoid injury to operatives. The photos show the loading of a joint of plain-end conductor. To load single joints or bundles of casing it is necessary to sling the pipe and to support it on the loading unit from a heavy scrap casing joint used as an extension to the lifting unit.
Small fork-lift aligns pipe joint with container.
Heavy fork-lift insets the prong of the lifting unit and takes the weight of the joint.
Heavy fork-lift loads the pipe to the container.
