Type C; Stand alone vessels, reels, manifolds
Type D; Control cabins, service units (integral strength in skin)
Type E; Falling outside the scope of 2.7-1/2.7-3/12079

Question 1:
“ROV Equipment mobilized to MOC Contracted offshore locations
(i.e. Rigs). At the time of demobilization from an offshore rig, how
do we lift equipment from the rig if the ROV equipment is not
considered suitable for offshore lifting?”
Response:
In terms of the specified requirements, as referenced via the MOC
LOM, LOLER, UKOOA etc, if the equipment is not considered
suitable for lifting, the simple answer is that it is not lifted!
Unrealistic but reality in terms of specified requirements.

Obviously, the best approach is to have process and practices in place to
ensure that equipment does not get to a condition where it is
unsuitable to lift - NAMELY
In an instance such as this, it would be recommended that a thorough,
documented risk assessment is performed using personnel competent
in lifting equipment, structures and practices to determine if the
equipment is in fact unsuitable to lift or to implement measures that
would mitigate the possible risks involved, at least until the equipment
was back to shore where it could be evaluated further.

Question 2:
“Other than a sea container designed and built to DNV 2.7-1
construction rules how do you confirm equipment is suitable for
offshore lifting i.e. EHPU, an A Frame. An Umbilical Winch.”
Response:
In terms of the specified requirements, as referenced via the MOC
LOM or by using the principles used for a sea container, in this
case the use of DNV 2.7-3 could be applied by;
• Design review and verification
• Conformity of fabrication to design requirements
• Conformity of tests and inspections to design requirements
• Maintaining records as evidence of conformance, such as the

Certificate of Conformity and as built dossier
• Ensuring compliance of the equipment is maintained to the
original design specification by implementing the OEM
recommended periodic maintenance along with records as
evidence of compliance.

Question 3:
“Must all equipment be weighed to determine proof of weight?”
Response:
Based on the references quoted, there is a requirement for
weight to be identified.
MOC LOM 6.4.1; “…every lifting appliance shall have an SWL”
(Safe Working Load)
DNV 2.7-1 at 6.3 and BS EN ISO 12079-1 at 9.3 states; “Maximum
gross mass (Kg), Tare mass (Kg) & Payload (Kg).”
DNV 2.7-3 at 6.2 states; “The maximum gross weight (mass) also
if applicable the tare mass and the payload.”
There are a number of ways that the weight can be determined
such as assembly calculations, drawings or the use of a load cell.

In place with the MOC Logistics group for the delivery of equipment to
the MOC Supply Base is a cargo transfer checklist where there are two
points that must also be considered for “proof or weight,” for the lifted
equipment and associated lifting accessories, which are;
► Check Safe Working Load (SWL)
► Check loaded item is within the weight limit
This checklist is completed by all Contractors prior to releasing
equipment to the MOC Supply Base and then cross checked by the MOC
Logistics group.
One final point in relation to weight is the distribution of the weight of
any lifted equipment where there are guidance notes, in the case of
CCU’s specified requirements, to ensure the lift is balanced (±50) from
centre) and when suspended, a lift must be level in both axes, <3% of
length/breadth (equivalent to 6” in 20’, 18” in 50’).

Question 4:
“Equipment lifted from vessels deployed to seabed through the
water column. If a piece of equipment (Large subsea tool or static
object) is deployed from a boat overboard to the sea, what
criteria must be met and supplied as evidence before the item is
deemed fit for use?”
Response:
Pretty much the same response to question 2 in terms of what is
required.
• Design review and verification
• Conformity of fabrication to design requirements
• Conformity of tests and inspections to design requirements
• Maintaining records as evidence of conformance, such as the

Certificate of Conformity and as built dossier
• Ensuring compliance of the equipment is maintained to the original
design specification by implementing the OEM recommended
periodic maintenance along with records as evidence of
compliance.
Specifically ISO 13628-8 (2002) “ROV interfaces on subsea production
systems” may be worth consideration, or at least ISO 13628-1 Annex K.
DNV 2.7-3 also consider subsea design in chapter 3.11.
Summary
In general terms, lifted equipment and accessories are no different from
any other equipment that is used during drilling and completion
operations in that the equipment is designed, manufactured, tested,
inspected, maintained and preserved to defined criteria with
documented evidence of conformance available.

Questions???
For further clarification related to any point
from the presentation, please speak with any
