Okay. I'll go through the physical response times very quickly, but again, bear in mind the points I made.
In Australia, as an example, search and rescue is governed, as in most countries, by the Department of Defence or the federal government. They have the mandate to respond, but there are no physical assets dedicated to the civil marine and oil and gas industries. They have search and rescue efforts of opportunity. In other words, if an emergency happens, they have some 60 fixed-wing and rotary-wing aircraft they can deploy to a given location, depending on what they are doing currently.
What does that mean? When they say they have a “wheels-up” time of 30 minutes, the time it takes to launch the helicopter, that's 30 minutes to find a civil aircraft and to launch that aircraft to a location, if one is available. However, the defence resources are not dedicated to oil and gas; they are dedicated to air force response, primarily when pilots are in training.
So the Australian Defence Force has a 30-minute wheels-up response time. Civil search and rescue units launch within five minutes to one hour; however, the five minutes is questionable, because it really depends on how the aircraft is configured and what that aircraft will do. Some of these search and rescue assets are not, as you might imagine, a Cougar helicopter or a helicopter from Gander or somewhere else, but they have five minutes to one hour. Others, in other parts of the country, launch in 15 minutes. Other oil and gas operators have no response times because there are no aircraft that can respond on their behalf. It's all done by aircraft of opportunity.
In the U.S.A. 30 minutes is the standard. If you're looking at the federal government, the United States Coast Guard, you're looking at a 30-minute response. They have 30 minutes to get up in the air. Then they have a number of hours to be physically on location. However, private industry also participates in search and rescue for marine operations. The Cougar is launched in operation in the Gulf of Mexico and has a response time of 20 minutes in the day and 45 minutes at night. Chevron has a fleet of some 17 helicopters that launch in 45 minutes day and night. However, they only can do medevacs; they can't do search and rescue and they can't fly at night, etc., so again one must consider all the factors when looking at these numbers.
With regard to Mexico, one would think that Mexico would have a terrible response infrastructure. There are some 5,000 people working on installations in two regions, meaning 10,000 in total, and there is a fleet of 27 helicopters to service them. None are equipped for search and rescue, so the military do that on their behalf, but their wheels-up time is 40 minutes, day and night. Their response requirements are somewhat limited because each installation has a doctor on board, so if there's an urgent medevac to be conducted, a doctor on board can physically attend to the patient much more than could be done in other areas.
In the United Kingdom, the Maritime and Coastguard Agency times are 15 minutes between 0800 and 2200 and 45 minutes between 2200 and 0800. Those assets, though, are now civil assets: the coast guard manages the operation, but the assets are owned by private helicopter companies. In many ways that type of operation is a lot easier to manage, because they don't have the restrictions that a federal department might.
