ARCTIC OPERATIONS
Presenter: Ole Lund
Operations Manager EAME
DOLPHIN GEOPHYSICAL
- Company started in 2011
- A full service marine geophysical company providing high quality:
• Contract seismic
• Multi-Client
• Processing
- Long term charter of a fleet of 8 seismic vessels:
• Long term charter of seven modern 3D high-end vessels, of which four are to be delivered in 2013, 2014 and 2015
• One ice-class 2D vessel
OFFSHORE TOWED SEISMIC SURVEY OPERATIONS
2D – Single streamer and single source 3D – Multiple streamers, and normally dual source Streamers can be up to 12km long Multi-streamer vessels can tow up to 14streamers with 100m separation
WHY DO WE OPERATE IN THE ARCTIC
• The different nations present in the Arctic want to map the seafloor
• Initial search for hydrocarbons
• Speculative companies want to invest in seismic data in case of future openings
• A higher demand for oil and gas
• The environmental conditions seem to be improving together with resources more developped
HOW DO WE OPERATE IN THE ARCTIC – PREPARATIONS
Before any project, we are required to do some preparations to avoid compromising on health, safety and environmental concerns. Below are a few keywords:
• Project Risk Assessment/HAZID
• Medical Emergency Response Plan(MERP)
• Project HSE plan
• Emergency Notification Charts
• Logistics plan
• Insurance
• Environmental Impact Assessment
• Permits
• Ice forecast
HOW DO WE OPERATE IN THE ARCTIC – SUPPORT
• Icebreaker
• Support vessel
• Guard Vessel(s)
• Coastguard support
• Extra spare parts
• Helicopter support
• Crew vessel
• Dedicated agent and shore representative onshore in the area
• Dedicated shore organisation for the project
• Contact with weather and ice forecasters
• Ice Pilot and radar
All is Subject to location and requirements for the specific project
HOW DO WE OPERATE IN THE ARCTIC – EXECUTION
So, how is it done?
Today, only 2D is done in the ice infested areas, 3D is done during summer when no ice is present
For 2D and when heading in to the ice, all gear is submerged and goes below the Ice. The seismic vessel is modified to pull the gear down immediately behind the seismic vessel
Next is a few pictures
DOLPHIN GEOPHYSICAL EXPERIENCE
DOLPHIN GEOPHYSICAL - PICTURES FROM OPERATIONS
• Equipment need to be made and modified to be reliable in the rough environment
