4. Similarities between Offshore Wind and Oil & Gas
1. Activities
•
•
Piling Operations
•
Monopiles
•
Pre-piling
•
Post-piling
Versatile Jack-Ups are used to
support X-Y Frames
•
Pile Gripper frames for
piling operations
•
Cantilever Frame for Well
Interventions and well
plug and abandonment
works
2. Foundations
•
•
Monopiles
•
Wind Turbines
•
High Voltage Substations
•
Minimal Oil & Gas Platforms
Pre-piling and Post-piling of
Tripod and Jacket Foundations
•
Wind Turbines
•
High Voltage Substations
•
Minimal Oil & Gas Platforms
•
Oil & Gas Platforms
2. Foundations
2. Foundations
Example:
 Main difference = Quantity
Different Strategy in for example jacket installation
OWF = Pre-piling
+
Large quantity (WTG’s)
Post-piling
One-off operation (OHVS)
 O&G = Post-piling only so far
 Main reasons:
 Cost optimisation (no piling with expensive HLV)
 Flexibility in planning
Interface with fabrication
2. Foundations
Pre-piling
Pre-piling of foundation piles and jacket installation works
3. Quality, Health, Safety and Environment (QHSE)
•
QHSE Requirements are similar for Offshore Wind and Oil & Gas
•
•
•
OHSAS 18001 (Health & Safety Management System)
ISO 14001 (Environmental Management System)
ISO 9001 (Quality Management System)
•
Developement of Detailed Safety Cases to comply with Local
Laws and Regulations is mandatory for Oil & Gas
•
Training
•
•
•
BOSIET for Oil & Gas
• Includes Helicopter Landing and Escape
GWO Wind Training for Offshore Wind
• Includes Boatlanding and Manual Handling
Offshore Vessel Inspection Database (OVID) for Inspections of
Vessels in the Oil & Gas Industry
4. Equipment
•
Jack-Ups Neptune, Goliath and Innovation are suitable for
both Offshore Wind and Oil & Gas
•
X-Y frames are used in both industries
•
Auxiliary equipment (piling hammers, grouting spread,
ROV’s, …) is similar for both industries
•
Project specific equipment can be installed on the JackUps due to their large available deck space and large deck
loads.
