RIGGING DESIGN EXAMPLE

Problem:

Obtain sling, shackle and padeye sizes for lifting a 25 tonnes container offshore inaccordance with the APPEA “Guidelines for Lifting Equipment”

Assumptions:

- A 4 sling arrangement is assumed

- A maximum included angle of 60 degrees

- A 100/0 split of sling loads is assumed

- The centre of gravity is at the centroid of the padeyes

Sling size:

Referring to Table C4 in Appendix C of the APPEA “Guidelines for Lifting Equipment”,1770 grade wire rope with a 36mm nominal diameter has a safe working load of 27.4tonnes.

Shackle size:

Rc = 1.73 (refer to Table 1 AS1666.2 (1995))

Rm = 0.80 for shackles (refer to Table 5.4.1)

Rt = 1.00 for shackles (refer to Table 5.4.2)

Ro = 0.92 (interpolated from Table 5.4.3)

Factor of Safety = 4 = 5.43Rm Rt Ro

SWL = P x Rc = 25.0 t (SWL of sling assembly)FoS x 9.81

P = SWL x FoS x 9.81 = 770.5 kN (Minimum breaking force)Rc

Referring to AS2741-1992 Table 5, the grade S alloy dee shackle with a diameter of 38mmhas a min. destructive test force of 834 kN. This shackle has a WLL of 17 tonnes.

Padeye size

Referring to the Standard Drawing for Padeyes and Shackles (W2090-SKS01 Rev B), thecorresponding padeye to the shackle designed above is the padeye with a WLL of 17

tonnes.

APPENDIX H

GUIDELINES FOR THE PHASE OUT OF ISO SHIPPING

CONTAINERS OFFSHORE

7/14/2019 Pdeyes



Page 74

SCOPE

Provision of procedures & guidelines to manage the use of ISO containersused in the offshore oil and gas exploration and production industry.

The document provides guidelines for the inspection, testing and marking of

ISO containers used in the transport of goods to and from offshore locations.

IDENTIFICATION OF

“ISO” CONTAINERS

ISO containers are the containers originally built for international shipping andfitted with ISO Corner fittings and lifted in container ports, from these fittings,with a purpose built spreader frame and special “Twist-locks”. The containersare designed and rated for use in still water ports and not for offshore use

where significant dynamic forces occur during lifting operations.

Most ISO containers are 20ft in length although 10, 30 & 40ft lengths are also

available.

Note: Purpose built offshore containers may also have ISO Corner fittings.

This is acceptable, provided that they are used only for securing duringtransport and/or onshore/inshore lifting in accordance with onshore/inshorecontainer lifting guidelines as detailed in AS 3711.10:1993 “Freight

Containers – Handling and Securing”.

CONTROLLED USE OF

ISO CONTAINERS

Containers used in international shipping are controlled by the International

Convention for Safe Containers (CSC). When the containers used ininternational and/or coastal shipping reach the end of their service life, either through condition or a “time life” expiry they are often sold off withoutcurrent CSC compliance.

Existing CSC compliance plates do not apply to the offshore oil and gasexploration and production industry except as a reference for de-rating the

container in accordance with this these guidelines.

The CSC compliance plate is to be retained for this purpose. ISO containerswithout compliance plates should be condemned.

ALLOWABLE ISO

CONTAINER STYLES& LENGTHS

Closed roof, ISO containers up to 20 ft. in length are acceptable for offshore

transportation in accordance with these guidelines.

Open top style, ISO containers and any ISO container over 20 ft in length arenot acceptable for offshore transportation.

MODIFICATIONS TO

ISO CONTAINERS

Any ISO container that has been modified from the original CSC design must

have engineering calculations to support the continued integrity of thecontainer.

Unlike a purpose built offshore container, which is designed to carry full loadon primary structure members, ISO containers rely on the integrity of wall panels for primary strength.

Such modifications may include:• Addition of extra doorway

• Alteration to length

• Addition of Pad eyes

PHASING OUT ISO

CONTAINERS FROM

OFFSHORE

INDUSTRY

Contractors currently utilising ISO containers are expected to reduce thenumber in use up to the phase out date of 31 December 2000 and replace them

with purpose built offshore shipping containers.

The APPEA Guidelines for Lifting Equipment provide guidance for the design

of purpose built offshore shipping containers.

COMMENTARY ONLIFTING POINTS

• Even in a still water port situation, ISO shipping containers cannot belifted from the ISO Corner fittings by shackles and slings. This applies

even when empty.

• Lifting with spreader frames as used in port situations is not allowed in

offshore lifting operations. Refer to IMO MSC circular 860

ISO containers used in the offshore industry should have pad eyes that are purpose built. Refer to “Pad eyes” below.

Figure 3: Shackles in ISO corner fittings are not permitted Figure 4: Although not generally required when container is

down-rated, lifting with special lifting beams will be allowed

during phase out. Must be fitted to pad eyes as shown.

7/14/2019 Pdeyes



Page 76

PAD EYE

REQUIREMENTS

The following guidance is provided for the installation of pad eyes:

• design by qualified structural engineer;

• design verification by independent engineer, who has not been involved in

the design;

• carry MGM on 2 diagonally opposite pad eyes;

• align to the centre of gravity of the load• shackle pin hole to be +3mm or, not greater than 4% more than the

shackle pin diameter;

• width of pad eye to be equal to 75% of the opening of shackle to be fitted.

This may be accomplished by fitting bosses to pad eye;

• material trace-ability;

• documented welding procedures (To AS1554, AWSD1.1 etc.);

• welder qualification trace-ability; and

• NDT inspection of all welding associated with pad eyes.

Notes:

1. The installation of pad eyes must have engineering trace-ability.

2. Refer to section 5.8 for pad eye design.

ALLOWABLE MGM

(Maximum Gross Mass)

ISO Containers used in the offshore industry where significant dynamic forcesoccur during lifting from supply vessels must be significantly de-rated.

Subject to inspections in accordance with these guidelines, ISO container useup to the phase out date will be allowed provided that the following is applied:

• The container is de-rated by multiplying original CSC Maximum GrossWeight (or Mass) x 2 and dividing the figure by 5.eg. For a 24 tonne MGM container:

(24 x 2) =9.6 tonnes MGM

5

MARKING

REQUIREMENTS

All ISO containers, original or modified, shall have a stencilled marking beside the CSC data plates indicating “Not Applicable”. The plate should

remain to indicate the original MGM that is used in the de-rating formulaabove.

Marking plates are required for:

• Operational Marking Plate (Tare, Nett & Gross)

• Test Plate (date of test and inspections)

Each container should be marked with a unique identification number issued by the owner. The number should be:

1. cross-referenced on all relevant documentation; and2. prominently displayed on a minimum of 2 sides of the container in

contrasting colours with stencilled characters of not less than 75 mm in

height.

Note: Refer to Figures 5 &6 for details of plates.

7/14/2019 Pdeyes



Page 77

FORKLIFT POCKETS ISO Containers often have more than 1 set of fork-lift pockets. Extremecaution should be used when lifting a laden ISO container from the fork-lift pockets.

If there are two sets of fork-lift pockets, with one set being close to the centre

of the container, the inner set are designed for “Empty lifting only”. Thesewords must be stencilled on the base frame adjacent to fork-lift pockets whensuch fork-lift pockets are installed. Stencilling should be 75mm in height.

There are instances where ISO containers have been modified and appear tohave useable fork-lift pockets on more than two sides, this can be a dangerous

situation as fork-lift pockets have been found that have the fork tines bearingon a plywood floor. Check before using and at scheduled inspection.

SLINGS Sling sets may be chain or wire rope. The following is recommended:

• four leg sling assemblies are preferred;

• maximum included (apex) sling angle of 60 degrees and;

• chain used in stingers (or 5th leg) must meet ISO 3076, or ISO 7593standards.

Note: The use of stingers is discouraged as the redundancy in a 4 leg assemblyis lost.

SHACKLES Shackles must be:

• Grade “S” minimum; and

• Safety pin type with split pin fitted.

CONTAINER

INSPECTIONS

ISO containers must receive a thorough visual inspection both annually and prior to any load testing.

• NDT Inspection of pad eyes and floor support structure is to be carried outannually and prior to load testing.

• All thorough visual inspections and NDT must be recorded in a liftingequipment database.

THOROUGH VISUAL

& NDT INSPECTIONS

(ANNUAL

REQUIREMENT)

• door latching mechanisms in good working order (where applicable);

• container is free from obvious defects, corrosion, impact damage, cracks,etc;

• under-floor support structure inspection. The floor support structure isvery light in an ISO container and is prone to extensive corrosion andcracking when used in the offshore environment;

• place container on supports to allow full inspection of underside andensure adequate lighting;

• look for corrosion and/or any cracking;

• it may be necessary to sand blast corroded steel to allow full inspection;

• suspected areas of cracking to have NDT inspections carried out;

• steelwork that has suffered significant (greater than 10%) metal lossthrough corrosion is to be replaced;

• complete structure to be examined for corrosion, cracking, and impactdamage. Particular attention is to be given to inspection of lifting pointsand corner post assemblies;

• visually inspect all welds for defects;

• NDT all welds in pad eye area. (NATA accredited NDT facility required);

• inspect for signs of mechanical damage;

7/14/2019 Pdeyes



Page 78

• doors, frames, seals, hinges, locks should be examined and functionallychecked to ensure satisfactory operation without undue force;

• check floor is substantially flat with no signs of damage or other indications that may indicate overloading. Any internal floor damage may

indicate underside damage- re-check; and

• marking plates should be as per requirements of these guidelines.

VISUAL INSPECTORS

KNOWLEDGE

REQUIREMENTS

The visual inspector should have, as a minimum, a knowledge and adequate practical experience of:

• the statutory requirements relating to containers;

• the various types of containers in service;

• the correct methods of slinging and handling the containers;

• the loads affecting containers when handled under adverse offshore

conditions, particularly those affecting lifting points and, in the case of ISO containers used offshore, the floor support structure;

• the methods of testing containers as detailed in Maritime Safety.Committee circular 860 or, DNV2.7-1 Offshore Container, Certification Notes. The provisions of DNV 2.7-1 to be used as a guide only as ISOcontainers do not comply with offshore container standards;

• defects likely to be found in containers and acceptable levels of wear,distortion and deterioration in relation to safety in use;

• welding methods and procedures and qualification of welders;

• the various methods of non-destructive testing (NDT) and a goodunderstanding of how they work and their limitations; and

• procedures for measuring container to ensure distortion has not occurredduring service or load testing.

TESTING AN ISOCONTAINER

The target date for the phase out of ISO containers for use in the offshore oiland gas exploration and production industry is 31 December 2000. Hence it isrecommended that any containers currently in use undergo the following load

test (subject to satisfying inspection requirements) which would see themthrough to phase out date.

• Testing of container as per “Testing Requirements” as detailed in IMO613 & MSC 860. (Drop test will not be required)

TESTING

PROCEDURES

Prior to load testing carry out thorough visual inspection as detailed within thisdocument as there is no value in testing a container that has defects.

4 Point Lifting Test: Internal Load (not to be hung under container): a uniformly distributed load,

such that the combined tare of the container and test load is equal to 2.5 timesthe de-rated MGM. The container should be lifted with its lifting set attached

to all four pad eyes.

2 Point Lifting Test: Internal load (not to be hung under container): a uniformly distributed loadsuch that the combined tare of the container and test load is equal to 1.5 timesthe de-rated MGM. It may be necessary to secure the weights to preventslippage during testing. The container should be lifted with slings attached to

two diagonally opposite pad eyes during the test.

Drop Test:Drop testing of ISO containers is not recommended. Drop testing is requiredwhen type testing future new container designs.

APPENDIX I

GUIDELINES FOR THE INSPECTION, TESTING AND MARKING OF

OFFSHORE CONTAINERS

7/14/2019 Pdeyes



Page 83

PREAMBLE

The purpose of these guidelines is to address integrity requirements for existing offshore containers. They donot address the requirements for new container fabrication or the concerns with ISO containers.

These guidelines provide lifting equipment testing facilities guidance on consistent minimum qualityrequirements for testing offshore containers.

APPEA encourages all offshore container owners and their agents to utilise inspection services that have beenaccredited by NATA (or equivalent overseas organisations) to carry out inspections and/or tests in accordance

with this guideline.

If the required documentation needed to obtain a “Certificate of Conformity” as detailed within this guideline isnot available to support the integrity of the container to be inspected and/or tested, the container should not beapproved for offshore use. This may require that engineering drawings be developed and calculations carriedout to verify the design of the container as being fit for intended service. Without all required information, a

“Certificate of Conformity” should not be given for the container.

7/14/2019 Pdeyes



Page 84

DOCUMENT SCOPE Provide guidelines for the inspection, testing and marking of a wide range of containers, baskets, skips etc. used in the offshore oil & gas exploration and

production industry.

INTRODUCTION The range of shapes, sizes and capacity of containers used in the offshoreindustry makes it difficult to specify all requirements that need to be met for

each individual design. This document provides specifics on some mattersaffecting safety of containers whilst other areas may offer guidance only.

It is the joint responsibility of both the equipment owner and the inspectionand/or testing facility to ensure that all containers used within the offshore

industry are fit for the intended service.

COMMENTS ON

DESIGN OF

OFFSHORE

CONTAINERS

It is recognised that there are many containers in use within the Australianoffshore oil & gas industry that may not be correctly engineered for theservice. The guidelines and procedures provided in this document will assist

in ensuring that every container used within the oil and gas exploration and production industry has engineering drawings and design calculations to

support the Maximum Gross Weight indicated on the container.

Without the required documentation the testing facility will have no readymethod of determining if the Maximum Gross Weight (MGM) nominated by

the owner, is in fact a safe working load to be applied.

New containers will be fabricated to stringent guidelines and will be built to

recognised standards such as DNV 2.7-1. This will automatically provide thequality that this document seeks to introduce to existing containers.

JUSTIFICATION OF

ALLOWABLE MGM

(Maximum Gross Mass)OF EXISTING

CONTAINERS

Existing containers may need to be down-rated due to the more stringenttesting requirements. It is recommended that container owners carry out a

review of existing design MGM ratings to ensure that the container(s) willmeet the testing requirements of 2.5 times MGM. It may be necessary torevise the container MGM and to update drawings as required, indicating newratings.

7/14/2019 Pdeyes



Page 85

PAD EYE

REQUIREMENTS

One of the most critical areas in the fabrication of an offshore container is the

pad eyes and their attachment to the container. For this reason the followingare recommended for offshore containers.

• the installation of pad eyes must be carried out in accordance with goodengineering practices;

• no “bolted on” pad eyes are permitted;

• pad eyes must be welded to the primary structure of the container;Note: For existing containers of monocoque construction, a detailed

engineering assessment of the pad eye connection is required;

• design carried out by a qualified structural engineer and checked by an

independent engineer;

• for design purposes, the design load is to be carried on two diagonally

opposite pad eyes;

• align to centre of gravity of the loaded container;

• shackle pin hole to be +3mm or, not greater than 4% more than theshackle pin diameter;

• width of pad eye to be equal to 75% of the opening of shackle to be fitted.This may be accomplished by fitting bosses (cheek plates) to pad eye;

• material traceability where appropriate material with through thickness properties is to be specified. (Lamellar Defects);

• documented welding procedures (To AS1554, AWSD1.1 etc.);

• welder qualification trace-ability; and

• NDT inspection of welding by MPI for all fillet welds & a combination of

Ultra Sonic and MPI for full penetration welds.Notes:

1. The installation of pad eyes must have engineering trace-ability.2. DNV 2.7-1 provides full details of container design and material

requirements and designers are encouraged to use the DNV document as a

guide.

GENERAL DESIGN

REQUIREMENTS• Monocoque construction is not to be used in new offshore container

fabrication and/or designs ie. A “Primary structure” is required.

• For all other design requirements for new offshore containers, refer toDNV2.7-1 “Certification Notes – Offshore Containers”.

.

MARKING

REQUIREMENTS

All Offshore containers shall have the following:

• Operational Marking Plate (Tare, Nett & Gross);

• Test Plate (date of tests and inspections); and

• Each container should be marked with a unique identification number

issued by the owner.Notes:

1. The above referenced “unique number” should be cross-referenced on allrelevant documentation, including the “Certificate of Conformity”.

2. The number should be prominently displayed on at least 2 sides of thecontainer in contrasting colours with stencilled characters of not less than75 mm in height.

COMMENTS ON

LOAD TESTING OF

OFFSHORECONTAINERS

The load test requirements for offshore containers used in Australian watershave traditionally been taken from Marine Orders Part 32 as published by the

Australian Maritime Safety Authority. However, it is recognised that the table published in Marine Orders Part 32 is not suited to offshore containers and

these guidelines recommend that the requirements of the InternationalMaritime Organisation (IMO) be applied.

IMO have issued a circular (613) that details testing requirements for offshorecontainers. This circular, referenced in Marine Orders part 44, paragraph 11 isto be replaced by circular MSC 860.

LOAD TESTING Prior to load testing, carry out thorough visual inspection as detailed withinthis document. There is no value in testing a container that has defects.

NDTCarry out NDT inspection on pad eye welds prior to and following load

testing. There will be no point load testing if pad eye welds have existingfaults.

4 Point Lifting Test: Internal Load (not to be hung under container): a uniformly distributed load,such that the combined tare of the container and test load is equal to 2.5 times

the rated MGM. The container should be lifted with its lifting set attached toall four pad eyes.

2 Point Lifting Test: Internal load (not to be hung under container): a uniformly distributed loadsuch that the combined tare of the container and test load is equal to 1.5 times

the rated MGM. The container should be lifted with slings attached to two

diagonally opposite pad eyes during the test.

DOCUMENTATION

REQUIREMENTS

PRIOR TO

LOAD-TESTING

The following requirements apply to any offshore container including baskets, bottle racks, waste skips, completion baskets, workshops, stores and any other structure used to transport goods to and from offshore facilities.

The equipment owner (or user) is required to provide the testing facility withadvice regarding design drawings and design calculations as detailed onPage92.This information is required to enable the testing authority to issue aCertificate of Conformity that will confirm that the subject container meets therequirements of these Guidelines.

COMMENTARY ON

TESTING OF

WORKSHOP

CONTAINERS,LOGGING UNITS

ETC.

It is recognised that it is extremely difficult, and in some cases impossible, tofit the required test weights into containers that have work benches, shelving

etc. It is also impossible to fit weights into many logging units and other container style cabins that either are full of specialised equipment used by

service companies or, only have personnel access doors.

In the case of these units it is recommended that more stringent inspection

requirements apply to these units in lieu of any load testing.

6 YEARLY

INSPECTION OF

WORKSHOP

CONTAINERS,

LOGGING UNITS

ETC. THAT CANNOTBE LOAD TESTED

Where test weights cannot be evenly distributed across the floor area of any

container, logging unit etc. the following inspection methods shall be used toensure the on-going integrity of the equipment. These requirements shall beadditional to the annual, thorough visual and NDT inspection requirements previously outlined.

Note: This method of integrity assurance will be in lieu of load testing and willonly be carried out by facilities accredited with NATA for visual or NDT

inspection or Classification Societies (e.g. DNV, Lloyds etc.)

• Place container on racks to allow full underside inspection.Note: Do NOT walk underneath containers suspended by fork-lift or cranes.

• Abrasive blast 25% of under-floor structural welds.

• Carry out MPI on all welds cleaned by blasting

• Where cracking is found in the underside should be completely abrasivecleaned and all structural welds inspected by MPI method.

• Carry out UT testing of any under-side structural members suspected of having areas of > 10% metal loss.

Note: If any metal loss of > 10% is detected, the remaining structuralmembers shall also be UT checked for metal loss.

• Carry out repairs as required using approved welding procedures,qualified welders and trace-able materials equivalent to the originalstructure members as detailed on the engineering drawings.

• Carry out MPI on all weld repairs and rectify any faults detected.

• Re-coat underside of container with a suitable coating for the offshoreenvironment.

• NATA accredited facility shall provide the equipment owner with a “stick diagram” of the container underside. The diagram shall identify membersand joints inspected.

• The equipment owner should ensure that all QA documents relating torepairs carried out are complied and retained on file for future reference.

Note: Whilst the abrasive blast requirements may, at first seem to be quiteextensive, it will, in most cases be advantageous as many containers willrequire re-application of coatings (particularly underneath) at the end of 6years and this work will fit well with that requirement.
