DNV 2.7-1 / EN 12079-2 review

 Limitations:

  • Maximum rating is 25T
  • The DNV 2.7-1 standard corresponds only to offshore containers

p y fabrication, but the part concerning the lifting sets is often used as reference for the fabrication of slings for other offshore equipments

  • Enhancement factor to be applied for the calculation of the WLL

(see table 8-1 at right side)

  • Minimum WLL = 7 000 kg
  • Certified process of fabrication
  • Top link dimension: recommended > 270 x 140mm
  • When unloaded, the top link must not be above 1300mm from the

p floor

  • Maximum angle of a sling with vertical = 45°
  • The shackles from a lifting set can not be separated from the

g p sling

  • Hard eye assembly only

EN 13414-1 review

 Limitations:

  • Wire rope sling fabrication, from 8 to 60mm
  • Specific marking

p g

  • Swaging conform to EN 13411-3
  • WLL to be calculated for angles from 0° to 45° from vertical (and from 45° to 60° for some

specific assemblies) p )

  • The weakest part must be the cable, not the top link
  • Shackles must have higher WLL than the leg they are connected to
  • Calculation of the WLL for usual cases:
  • Calculation of the WLL for usual cases:
  • For 1 leg sling: WLL = (BLmin x KT) / (g x ZP), with:
  • BLmin = Minimum Breaking Load of the cable (given by the supplier)
  • ZP = 5 (safety factor)
  • g = 9.80665 N/kg
  • KT = termination coefficient (0.9 for swage assembly)
  • For multi legs sling: WLL = (BLmin x KT x KL) / (g x ZP), with:
  • KL = coefficient for leg number and angle = Nlegs x cos(β), with β = 45°
  • KL = 1.4 for 2 legs slings, and KL = 2.1 for 3 and 4 legs slings (4 legs slings are calculated as 3 legs slings)

How to chose a lifting set ?

 Number of legs:  Number of legs:

  • Given by the design of the equipment to lift

 Requested certification

  • Offshore or onshore ?
  • One time lift for installation or movable equipment ?
  • Company specifications
  • Company specifications

 Calculation of the minimum WLL of the sling

  • Weight of the equipment to lift
  • DAF to apply (generally given by Company specification)
  • Example: in TOTAL specifications, DAF = 1.30 for offshore lifting (<150T), and DAF = 1.10 for onshore

 Use of a spreader bar:  Use of a spreader bar:

  • Can lower the stress on the equipment during lifting
  • Can reduce the length of the sling

C ll b tt t l f th lifti ( i ll f l f b i t )

  • Can allow better control of the lifting (especially useful for subsea equipments)
  • May modify the stability of the equipment (to be checked in every particular case)
  • Must be subject to specific calculation note

Some answers to the most frequent questions you have:

 What are the advantages of conical ferrules for swaging?

  • It is safer for manual handling, as there are no more free strands out of the ferrule
  • The profiled end has less risk to catch a sharp edge while dragging the sling

Conical end, covering Specific dyes for swaging the free strands Hole for control of wire rope extra length Cylindrical body, similar to “standard” ferrules

 Are you sure it is allowed for DNV 2.7-1 lifting sets fabrication?

  • Yes: DNV 2.7-1 standard states that: “The terminations of wire rope legs shall be ferrule

secured eyes with thimbles, and comply with EN 13411-3 or other recognized standard.” (§8.3.2.2 Wire rope slings). The conical ferrules and corresponding swaging procedure we use are conform to EN 13411-3 (type C) therefore to DNV 2 7-1

Some answers to the most frequent questions you have:

 Why are you only using cables from diameter 18 to 32mm for DNV lifting sets ?

  • Even for the low ratings, the minimum WLL is 7000 kg (DNV 2.7-1, table 8-1)
  • Reference to EN 13414-1 for the cable  BLmin = (WLL x g x ZP) / (KT x KL) with:
  • ZP = 5 (safety factor)

9 80665 N/k

  • g = 9.80665 N/kg
  • KT = 0.9 (for swage termination)
  • KL = 2.1
  • BLmin = 179 840 N for the cable of a 4 leg sling
  • 18mm is the smallest cable size with BL > 179 840 N  not allowed to use smaller *
  • We use the same calculation for the maximum size, maximum rating is 25T, that gives a WLL
  • f 27 590 kg  BLmin = 708 830 N
  • 32mm is the smallest cable size with BL > 708 830 N  no need to use bigger

* It is actually possible to use a smaller size of cable by reducing the angle for a particular use ,if a specific t d d l l ti t i i d b t ll d ’t d it t id i f th li

non standard calculation note is issued, but we usually don’t do it to avoid misuse of the slings.

Some answers to the most frequent questions you have:

 What standards could I follow for a load > 25T as DNV 2.7-1 can’t apply?

  • First of all, the standard of each Company should apply
  • For onshore or one time lifting offshore, EN 13414-1 is most often used
  • DAF might be added for offshore use
  • DNV 2.7-3 Standard covers offshore equipments that are regularly lifted, up to 50T
  • No specific description of lifting sets
  • Reference to DNV 2.7-1  same lifting sets up to 25T
  • Above 25T, enhancement factor can be extrapolate at the constant value of 1.1
  • For other cases, a specific calculation note can be done for the lifting set

Some answers to the most frequent questions you have:

 Can you certify an existing sling ?

  • We can only make a certificate of conformity for our own manufactured products
  • Several issues occur to certify a sling fabricated by another manufacturer:
  • What material was used ? It is not possible to check the steel grade of the wire rope by mere visual

inspection

  • How was it assembled ? The process of assembly and the quality control along it are critical for the

certification of the final product

  • Alternative: we can make a load test under third party survey
  • Alternative: we can make a load test under third party survey

 Can you assemble a sling using our own material ?

  • Yes, if the material is compatible with our fabrication process. The composition of the cable is

a particularly important point to check, for compatibility with our swaging equipment. But the certification of the assembly is subject to the material certificate

 Can you modify an existing sling ?

  • Only if the sling was manufactured by ORSLING (same issues as for certification)

Some answers to the most frequent questions you have:

 Why should we work with ORSLING?

  • Quality of our final product, coming from the quality of the materials we use, the training and

dedication of our personnel

  • Reactivity of our workshop for emergency fabrication  we use to deliver urgent lifting sets on

the same day we receive the order the same day we receive the order

  • Fabrication inside SONILS base  no delay for material delivery
  • Frame contract with Bureau Veritas  reactivity for third party certification

y y

  • Adaptability to manufacture customized lifting sets
  • Pro-activity from our management and our engineering department to propose you the best

solution for your needs

  • Collaboration with other departments of FRIEDLANDER Angola to propose complete lifting

solutions like spreader bars or certified baskets solutions, like spreader bars or certified baskets
