Energy’s brightest innovators. This is the progress powering tomorrow. Allen Hall: Offshore wind obviously is a big deal right now. There’s a lot of, countries looking at it and investigating it, doing it, but not really at scale yet. And this is where ECO TLP comes in and. Nicole, let’s just start there with a background. What problem were you trying to solve when you started ECO TLP? Nicole Johnson-Murphy: Yeah, so, we were designing for, a site off of Hawaii in 2011, for the HECO RFP. And so we were designing for 300 meter water depth from the beginning. so we were always trying to find a way to work with the ports, with the vessel, with the infrastructure that was existing off Hawaii. And with, and that worked with Jones Act vessels. So we were always trying to meet that [00:01:00] requirement with, and meet the cost, try to, we saw there were much tighter margins in offshore wind than in oil and gas, for example, at that water depth. So we’re trying to find something that was cost effective. Allen Hall: Next question, obviously is what makes those deep water foundations so difficult? Gordon Jackson: It’s the water depth, primarily, you need to put foundations down in, extremely deep water. and they’re gonna be pretty flexible. so you’re trying to control the amount of motion that you get at the surface through your, your deep water, facility. it’s really. Really that challenge, and, the weight of components through the water depth, likes of chain would be completely impossible. in 300 meters of water. you need to use something that’s a little bit lighter. Yeah, to mow you to the, to the seabed. Allen Hall: [00:02:00] Because it does seem a little odd just not to make the foundations taller, basically. More steel drive it down in, we know that process, we understand that process. It works offshore, near shore in a, lot of locations. But once you get to what depth as it becomes financially or engineering wise, impossible. Gordon Jackson: For offshore wind, fixed, structures in, maybe a hundred meters of water are gonna be. Economic. they’ll be costly compared to what’s been done now because, of all the extra structure you need for the, for the deeper water. But, I think you’ll see, a crossover between fixed and floating, around the, 70 to a hundred meter water mark. that’s sort the range. Allen Hall: And that leads to the next question, which is. It’s all financial, right? At some point, the numbers [00:03:00] don’t work. If the cost of foundations don’t come down, especially in fixed bottom offshore or floating offshore, we lose a lot of offshore wind resource. Nicole can you gimme a scale at what we’re missing if we don’t get to a more economical solution for floating offshore? Nicole Johnson-Murphy: So we’ve estimated for our market for, a very deep water market. So we now actually have a solution that goes across all water depths. So we’re starting with, this, gravity based structure now with, and, Gordon’s team has been really involved in that, development. And then now we can take that same slip form, concrete cylinder. Format and take it across all the water depths. so we basically can hit every water depth now for a very low cost. It’s a very simple, just, local, regionally designed and built, system. We, crowdsource the labor and the inputs. and so we [00:04:00] try to, and we also try to give the procurement team of our clients their, an ability to do their job and, be able to bid out aspects of our design, across. Different vendors. So you always wanna give, in construction, you always wanna give, the procurement team a job to do so they can actually get that price, keep that price down on the installation. Allen Hall: Yeah, that’s a unique look that ECO TLP is putting to this problem. Which is moving away from steel, which is expensive obviously, and it’s difficult to transport at times to a more localized solution, which is concrete. And thinking about the problem a little bit differently, does that open up a number of doors then in terms of the countries that can get involved in, floating or near shore, wind projects, but just because you’re driving the cost down? Nicole Johnson-Murphy: Absolutely. And I’ll let Gordon speak to that.. He’s worked. His whole ...
