The size and variety of General Cargo Baskets is diverse.Events over recent years have demonstrated that theproliferation of baskets in use needs to be addressed andmeasures put in place to standardise the design of newbaskets (and in time existing baskets) such that new buildsare similar in terms of design and dimension. Crucial areasare the standardisation of dimensions and stackingmethod.

The use of Cargo Baskets on and offshore is also an areaof great concern and the safe stowage of components incargo baskets requires those who are involved to be awareof the risks. A risk assessment of the activities shall beconducted to assess and establish a safe system of work.This shall take into account the need for pre - planningduring the loading and stowage and include anynecessary evaluation of the manual and mechanicalhandling risk and access/egress to the basket. Thepersonnel involved shall be competent in stowage ofcomponents into cargo baskets this will include sufficientknowledge, experience and training in the use of cranes,forklift trucks, manual handling and banksman / slingerwhere appropriate, commensurate with theirresponsibilities.

This document sets out guidelines and recommendationsin order to achieve these goals.

1.1 Scope

This guidance is relevant to the design of new build cargobaskets ≥ 10 metres in length (for baskets ≤ 10m in length,similar designs may be adopted in due course).

This guidance is also relevant to the Safe Preparation,Handling and Transportation of all Cargo Baskets to andfrom Offshore.

Baskets not complying with these guidelines will bephased out of use by 2010.

The recommendations in this guidance are in addition tothe requirements of BS EN12079 and / or DNV CN2.7-1.

NB: The British Standard BS7072 (1989) is considered aswithdrawn and all new baskets shall be manufactured toBS EN12079 and / or DNV CN2.7-1 . Existing Basketsmade to BS7072 prior to October 1999 may still be used inthe UK at this time.

1.2 Definitions

1.2.1 Primary structure

As defined in BS EN12079 and DNV CN2.7-1.

1.2.2 Cargo Basket

An open top container for general or special cargo.Normally not more than 1830mm wide.

1.2.3 Special

A cargo basket that has been designed for a specificpiece of equipment and is not used for any purpose otherthan that.

N.B: For these special purpose baskets it is anticipatedthat these guidelines shall be applied as far as reasonablypracticable.

Page 5: 15_Design and Handling of Cargo Baskets

2.0 Standard dimensions

The standard dimensions shall be as per the followingtable:

Table of standard basket dimensions

X = Recommended basket dimension.

N/R = These basket dimension are not recommended(N/R).

2.1 Lengths

Lengths of baskets shall be standardised as follows:

10metres, 12metres, 14metres and 16metres - maximumexternal dimension.

(NB: length was limited to 16m based on maximum lengthreadily transported by road).

2.2 Widths

Widths of baskets shall be standardised as follows:

610mm, 1220mm and 1830mm - external dimension.

(Note: Widths were derived based on compatibility for roadtransport).

2.3 Height

Baskets greater than or equal to 10m in length shall notexceed 1120mm at top rail. Excluding pad eyes andstacking mechanism.

(NB: Height was derived from using an angle of tilt of 15degrees for 2-stacked baskets 610mm external width.(Typical intact stability damage angle for a SemiSubmersible Drilling Unit)

Where a requirement for a basket out- with the abovedimensions has been identified due to specific cargo orequipment, this will be considered as a special. (Ref. 1.2.3)

12.1 Planning / Design Engineer

The Design Engineer responsible for the design ofcomponents (Cargo) must take into account the supplychain requirements before procurement / selection of aCargo Basket, consideration given to the limits of availabledeck space, lifting and securing of components into anappropriate standard size Cargo Basket and thearrangement at the consignee final destination.

12.2 Cargo Basket Selection (Planning and Loading)

The correct selection of the appropriate basket is veryimportant. Due consideration must be given to thefollowing factors that affect the size and type to be used:

1) The characteristics of the components.

2) The loading and unloading restrictions that may beencountered.

3) The mode(s) of transport and any foreseeableconditions that may be encountered.

4) The availability and suitability.

5) The dimensions and gross weight of the loaded basketand the mode of carriage and any problems that couldbe encountered with the traffic regulations en-routewhere applicable.

12.3 Loading and Forwarding

The vendor must obtain information and / or seekassurance prior to the dispatch of a cargo basket(s) thatthe proper lifting equipment and facilities are suitable ateach stage involving loading, unloading during transit andalso at the final destination to ascertain if:

1) The site(s) have adequate overhead / mobile cranes orforklift trucks.

2) The site(s) lifting equipment is suitable and within thecapacity needed.

3) There is a dedicated area for loading and unloadingoperations and is it adequate and suitable.

4) Access and egress is sufficient and free from anyrestrictions or other imposed limits at the sites such asvehicle size etc.

5) There are any special site requirements needed such asan induction etc.

NB: The vendor will normally only need to gather theinformation once if the shipping arrangementsinvolved are handled by the same sites on a routinebasis.

12.4 Loading Plans

Trained competent persons familiar with loadingoperations shall formulate loading plans. Adequatesupervision for routine and non-routine lifts shall beavailable as appropriate.

14

Page 16: 15_Design and Handling of Cargo Baskets

12.5 The Planning and Securing of Componentsinto Cargo Baskets

Before commencing the lifting operation an assessmentmust be worked out to secure the components into anycargo basket. Advice from a competent person shall besought. The assessment must take into account the goodscharacteristics and compatibility of strength and weight tobe loaded and produce a tight or secure load.

1) A standard size Cargo Basket should be selected fromthe sizes specified section 2.0 of this guidance.

2) The planned load must not exceed the pay load of theCargo Basket, which is stated on the certification anddata plate.

3) The Cargo Basket shall be designed assuming that theload is to be evenly distributed over the complete floorarea of the basket. Where there is substantial deviationfrom uniform loading slings manufactured to suit theCentre of Gravity of the Loaded Basket shall be used.

4) The loading of all baskets shall be such that nocomponents exceed the external dimensions of thebasket. It is however recognised that in some instances,the cargo may protrude above the top rail of the basket,at no time should the cargo protrude out with thesidewalls or end of the basket. In these cases a detailedrisk assessment must be completed to take intoconsideration the snagging of the cargo by lifting setsand movement during transit which may result in cargofalling outwith the basket.

5) The planning must take into account any problems ofrestricted access or egress and to the availability ofmechanical lifting aids, the use of forklift trucks and themanual handling risks at final destination such as on anoffshore installation.

6) Due consideration should be taken to any shock orimpact during load/unload which may have adetromental effect on the securing arangement integrity.

7) The lifting set shall be made easily accessibility insecure position at or near the top of the basket to allowfor handling and attaching during loading or unloadingin the transport operations. The location of the lifting setinside the basket shall not pose a snagging hazardwhen being lifted.

15

Page 17: 15_Design and Handling of Cargo Baskets

13.1 Cargo Basket Selection

All Baskets shall comply with BS EN12079 and / or DNVCN2.7-1 and have valid certification.

Baskets shall:

1. Be of a size that accommodates the contents but notgreater than a Maximum of 15% of the length.

2. Be balanced to lift horizontally.

3. Be stackable to allow safe stacking of compatiblebaskets for optimum storage offshore (max 2 high).

4. Allow for sighting of lifting gear for easy access andprevention of snagging.

5. Items that meet the classification criteria of dangerousgoods or any items so packed marked or labelled willnot be dispatched in a cargo basket unless competentauthority approval has been gained from the MCA

13.2 Inspection of Cargo Basketsbefore Loading.

The Users Representative on all Cargo Baskets must carryout a visual inspection internally and externally prior toloading. This inspection must ensure that the CargoBasket is fit for purpose with no evident damage, whichmay result in the Cargo Basket being a safety risk.

Where the Cargo Basket is not in a satisfactory condition itmust be replaced.

The following is a recommended list of inspection pointsthat shall be used as guidance before loading a CargoBasket:

13.2.1 External Inspection Checks

Adequate lighting provisions must be made to perform asuitable inspection of the cargo basket prior to use.

The inspection should cover the following aspects:

1) The main primary structural framework of the cornerposts, longitudinal top and bottom base rails on all foursides must be free from any visable mechanicaldamage and / or evidence of deterioration.

2) Pad eyes should be in good condition and the shackleshould be a tight fit with hole size being within 6% of thepin diameter and pad eye filling 75% of the shackle gap.

3) The Basket shall be identified and traceable to thecertification

4) A valid data plate should be fitted to the basket.

5) Markings shall be visible as specified in BS EN12079,DNV CN2.7-1 and this document. (See section 10.0).

6) There must not be any significant deformation of thesidewalls or floor which effects the integrity of thebasket.

7) Any labels or marking from previous cargoes that do notrelate to the current load must be removed or covered.

13.2.2 Internal Inspection Checks

1) The basket must be free from any visable damage. Payparticular attention to the floor condition and anyprotrusions that could cause injury to personnel ordamage cargo.

2) The cargo tie down points must be in good condition.(See section 9.0).

3) All sling sets must be protected from mechanical orphysical damage.

4) Ensure draining holes are unblocked and are free fromdebris

13.3 Loading the Cargo Basket

For the safe handling of cargo during loading there mustbe sufficient means of access and egress to the loadingarea taking into account the load and any mechanicalhandling aids.

The cargo shall be evenly distributed over the length andbreadth of the Cargo Basket as far as reasonablypracticable. If cargo items of varying mass are to bepacked into a cargo basket, or where the basket will not beloaded to capacity, either because of insufficient cargo orbecause the maximum allowable gross mass will bereached; then: -

1. The components must be secured so that theapproximate centre of gravity of the components is asclose as possible to the mid length and mid width of thebasket.

16

Page 18: 15_Design and Handling of Cargo Baskets

If a Cargo Basket is to be loaded with an uneven weightdistribution then slings should be supplied to suit theCentre of Gravity of the loaded basket. For return trip ofthe empty basket a 2nd set of slings shall be madeavailable and shipped out with the loaded basket.

Using bulks of timber metal structures or a water tank asballast is prohibited.

The cargo should be secured using lashing points asprovided ensuring that lashing points are not overloaded.The cargo tie down points or ring must be well anchoredand be in good condition. The cargo should be securedwhenever practical using ratchet type straps or purposedesigned securing mechanisms. The use of woodenchocks as a securing medium is not recommended.

The person or persons loading the baskets areaccountable for ensuring that the cargo basket is liftedprior to being dispatched to ensure stability and is liftedhorizontally.

17Typical means of lifting a basket to check for balance.

Page 19: 15_Design and Handling of Cargo Baskets

14.1 Securing of Cargo

The cargo basket must be securely fastened duringtransportation. The person(s) responsible for the packingof components into a cargo basket must secure the goodscorrectly as their actions can affect the safety of otherssuch as-

1) Drivers of road vehicles and other highway users.

2) Dock workers when the cargo basket is lifted on or off a ship.

3) The final consignees.

It is important that inspections and checks are made priorto loading and after the components are secured to ensurecargo basket are properly prepared for transport toprevent:

1) Damage to cargo.

2) Damage to the Cargo Basket.

3) Damage to the Cargo Baskets Lifting Set.

14.2 Vehicle Loading

When positioning a cargo basket onto a vehicle for thepurpose of loading ensure that:

The hand brake is applied and engine switched off beforeloading is commenced.

Mechanical hazards must be taken into account and it isessential that the cargo basket is secure against anyreasonably foreseeable movement taking into account themechanical forces of acceleration, deceleration andvibration.

The addition of vertical impacts may also occur duringhandling with forklift trucks or poor driver technique on theroad surface conditions.

It is the responsibility of the driver to ensure that the load isevenly distributed.

Page 20: 15_Design and Handling of Cargo Baskets

15.1 Risk Assessment

Risk Assessment. - Personnel involved in stowage, loading/ unloading of cargo baskets to / from vehicles, must takeinto account any potential risks. They must ensure thatadditional risks are not created during the operations thatcould affect the health and safety of personnel.

15.2 Load Security InspectionProcedure

All cargo baskets shall have attached a cargo tag to eitheridentify its current transit status as inbound or outboundcargo. The cargo tag shall be annotated by the relevantpersons to confirm that the cargo basket is properlyprepared, packed and sea fastened in a manner to satisfythe conditions that it could reasonably expected toencounter during transport: and

1) The cargo basket has been checked to ensure looseobjects are removed or secured.

2) The lifting accessories are certificated and fit forpurpose.

Drivers, Loaders and Vessel personnel shall ensure that nocargo basket is handled without a valid tag. A cargobasket dispatched without a tag shall be returned to thevendor.

The driver must pass the delivery documents to thereceiver to ensure that adequate provisions have beenmade for the cargo basket. The driver of the vehicle mustliaise with the receiver who will have an appointedcompetent person to deal with and supervise the siteoperations. The appointed person should be aware of theinherent risks and the necessary precautions needed toensure: -

1) Loading operations are properly planned taking intoaccount load characteristics and facilities.

2) The load is kept under control at all times.

3) The vehicle handbrake is applied and the engineswitched off during loading / unloading.

When loaded the driver must ensure, taking into accountany width or height restrictions that the vehicle can enter ordepart the loading area and site.

The driver must ensure that any loose objects are removedor secured before transit

Load Security Inspection Procedure

This procedure has been adapted from the Talisman Energy (UK) Ltd. process for ensuring the safety and security of cargo during transportation to andfrom offshore installations.

To this end, the term ‘Unit’ can be taken to be CCU’s (Cargo Carrying Units both closed and open top), Tubulars (slung or in frames), Waste Skips,Helifuel Tanks, Chemical Tanks, Specialist Loads (wire line units and other well service packages) Suppliers/Users of the above should nominate a Load

Checker within their organisation to ensure that the procedure is carried out and suitable verification methods implemented to provide an audit trail.

Onshore Load Checker

16.1 Onshore Yards

On arrival at the destination, if no adequate provisionshave been made available for the receipt of the cargobasket, then the driver and receiver shall take no furtheraction until such times as a plan for the safe loading /unloading of the basket has been established and agreed.

An assessment of the site conditions where handling andloading operations are to be conducted should include atleast: -

1) Obstructions such as snagging hazards, power cablesin the vicinity or parked vehicles.

2) Is there any ground condition that could give rise tocausing instability of the load, vehicles or lifting plantinvolved?

3) Unauthorised personnel who are not involved in theoperation.

Access to the vehicle or cargo basket during loading /unloading should be restricted. If there is a need to accessthe vehicle or cargo basket all personnel involved i.e.drivers, loaders and crane / fork-lift drivers should receiveclear instructions as to the actions to be taken, which mayinclude specified safe areas on the vehicle. Prior to anyaccess the following should be considered: -

1) An inspection from the ground should be conductedbefore anyone attempts to access the vehicle and thenonly mount the vehicle only if appropriate accessequipment (e.g. ladders) is available.

2) Only essential personal may access the vehicle.

As there is always a risk of a load any cargo basketbecoming loose or dislodged during transit then inspectionmust take place prior to any handling operations.

If at all possible inspection from an elevated position forexample loading gantry should take place. Any movementor loose objects must be secured or removed prior tohandling.

Cranes or other lifting equipment/accessories should beinspected before use and only operated by competentpersonnel.

1) Only certified lifting equipment or accessories which aresuitable for the task should be used and the safeworking load of that equipment should never beexceeded.

2) Personnel involved in slinging tasks or attaching liftingaccessories must be trained in the proper use of liftingequipment. All personnel must be clear of the vehiclebefore lifting commences.

Where cargo baskets have been placed adjacent to oneanother on vehicle trailers and where a forklift truck isbeing used to offload, caution must be taken to avoid thefork tips protruding beyond the basket being lifted and intothe pockets of the adjacent basket. Great care must betaken during this operation as there is potential to causedamage and personnel injury. It is strongly recommendedthat baskets loaded side by side be staggered on thevehicle trailer to ensure that the fork tips cannotinadvertently engage the adjacent basket causing it to bemoved or lifted.

16.2 Quayside / Rig Loading or offloading to or from Supply Vessel

All cargo baskets shall have a load security inspection tagattached to either identify its current transit status asinbound or outbound cargo. The cargo tag shall beannotated by the relevant persons to confirm that the cargobasket is properly prepared, packed and sea fastened in amanner to satisfy the conditions that it could reasonablyexpected to encounter during transport: see section 15.1and 15.2.

Before any activities / tasks involving lifting and or loweringoperations are attempted a task risk assessment must becompleted and the findings used to formulate lifting planswhere appropriate in accordance with LOLER and StepChange TRA (Task Risk Assessment) guidance.

Any cargo baskets or loads with configurations that couldcause significant danger to personnel or property must benotified by the vendor to the quayside, vessel or from shoreto offshore installation to ensure adequate provisions and awritten agreement is reached before transit.

Usually a planning meeting is convened on the vessel anda loading plan produced which the vessel master shouldcommunicate to focal point or crane operators at thequayside or offshore installations. Quayside and offshoreinstallations must also plan for the basket(s) with adequateprovisions made to ensure sufficient deck space or landingareas are prepared.

Materials controllers or other so designated persons mustprepare a manifest with an accurate basket weight andsizes recorded and communicate to the crane operator.

The Crane Operator shall clearly communicate to the deckcrew as to the nature of the cargo being offloaded from theattendant vessel. The lay-down area for the offloadedcargo should be clearly identified and communicated tothe deck crew prior to the load being offloaded.

Quayside or Deck operations will require a minimumnumber of personnel appropriate to the task, one will beagreed as the nominated banksman. Supply vessel deckoperations shall be in accordance with vessel operator’sprocedures.

16.3 General Workings of Supply Vessel

The UKOOA Guidelines have already established anddetailed these operations.

16.4 Unloading Cargo BasketsOnshore / Offshore

The UKOOA Guidelines detail the necessary precautionsto be taken during operations.

Consideration should be given to the positioning of thecargo basket when the task of unloading is to beconducted with safe adequate access and egress to andfrom the basket.

1) It is not advisable to access the cargo basket unless itis absolutely necessary and only after it has beensuitably risk assessed.

2) Non-slip mats or other access means can be used.

3) Personnel must not remain in the cargo basket duringloading / unloading operations.

4) On completion of handling operations the LiftEye/Master link should be positioned in such a mannerto allow unobstructed access to the link or eye for futurehandling operations.

Check that adequate provisions have been made to ensuredeck space availability and if necessary, re-arrangeexisting deck cargo to make space for the unloaded itemswith provisions made for sufficient dunnage.

No lifting operation shall commence without all personnelinvolved in the operation being fully conversant with thehazards associated with handling the lift. If at any timeduring the lifting operation there is a deviation from theoriginal plan or an unusual or unsafe event is observed thelift operation must be safely stopped and a re-assessmentcarried out prior to re-commencement of the operation.

17.1 Additional Deck Cargo BasketStacking Provisions

Avoid stacking baskets as far as reasonably practicable.

Each site’s deck-management (lifting management)standards must specify whether stacking is allowed at thatsite.

Ensure that the cargo basket is suitable for stacking andthe basket should be marked to identify its stackingacceptability i.e. Type A, B or C ascertain if there is astacking height restriction on the baskets and any if anyother local rules are in place.

Where stacking is allowed by site deck / liftingmanagement standards, then baskets may only bestacked when: -

A written lift plan and risk assessment pertinent to thespecific operation is in force and communicated to thoseinvolved with the operation (ref Step Change Lifting andMechanical Handling Guidelines):

1) The Cargo Baskets are designed and built to be stackedon each other in accordance with these guidelines:

(See section 8.0)

2) A certified system is used to act as a stacking mediumbetween baskets.

3) Use of dunnage is limited to protecting deck surfaceswhere single blocks of wood act as soft pads takingdirect vertical load.

4) Only baskets of the same width may be stacked on topof one another.

5) The basket is not stacked on an uneven surface that islikely to cause distortion.

6) Under no circumstances may dunnage or other baulks ofwood or similar be used to stack baskets.

Weather and installation characteristics pitch, roll andheave must be taken into account. If there is any doubt asto whether stacking can be achieved safely due to rigmotion the task must be immediately stopped andsuspended until environment factors improve.

Deck loading shall be checked prior to stacking any CargoBaskets.

When Cargo Baskets are stacked safe access shall bemade available to the lifting equipment. No person shallattempt to unload a cargo basket, which is stacked.

The banksman shall communicate with the deck crew whomust exercise care to keep clear of the basket duringmanoeuvring. Tag lines may be attached to assist thecrane operator when manoeuvring.

Deck crew shall only approach a basket when instructed todo so by the banksman and when the basket is landed inthe correct position and the load removed from the crane.

Deck crew when assisting in any stacking of cargo basketsshall limit manual intervention at all times to avoid thehazards associated with potential hand / finger injuries.

Baskets to be stacked will be limited to a maximum of twobaskets high.

Stacking is not permissible on Ships.
