0027-nd rev 11.2 8-jul-16 guidelines for marine lifting and lowering operations
15.2 CERTIFICATION, INSPECTION AND REVALIDATION OF SLINGS AND GROMMETS 15.2.1
All lifting equipment shall be in good condition and thoroughly inspected before each lift or series of
lifts. Special attention should be given to the condition of splices and terminations.
15.2.2
For slings and grommets used for offshore and inshore lifting, a valid certificate issued by a
Competent Person is to be provided showing that the sling or grommet has been inspected within the
past 6 months. The exception to this are slings and grommets used for general deck activities on the
crane vessel for which the onshore requirements are applicable provided there are no over the side
lifts in which case the offshore requirements still apply.
15.2.3
For slings and grommets used for onshore lifting, a valid certificate issued by a Competent Person is
to be provided showing that the sling or grommet has been inspected within the past 12 months. The
exceptions to this are slings and grommets used for the load-out operations to/from a vessel of
structures and any essential equipment required for its subsequent installation, for which the offshore
requirements are applicable.
15.2.4
For slings or grommets required to be wet stored for an extended period prior to use (e.g. for the
recovery of a subsea asset), if the storage period is anticipated beyond the inspection interval, the
means for satisfying any formal or regular inspection requirements should be agreed. The fabrication
requirements for wet stored slings and grommets are referenced in Section 14.2.12 for steel slings and
Section 14.3.11 for fibre slings.
15.2.5
For slings and grommets, a Manufacturer’s Certificate corresponding to the requirements in EN 10204,
Ref. [13], type 3.1 (or type 3.2) should be provided. For slings or grommets made of steel wire ropes
and used with a material factor of less than 1.5 (see Section 7.10.2), a 3.2 certificate (as defined in
EN 10204, issued or endorsed by a recognised Certifying Body) is required.
15.2.6
Safety factors and other restrictions or limitations imposed by other relevant directives/standards in a
Declaration of Conformity (if accepted as adequate certification) shall be adhered to. However, the
level of safety shall not be less than stated in this guideline. Note: a Declaration of Conformity is a
document signed and issued by the manufacturer to confirm the product meets all of the requirements
of the applicable directives.
