If you overengineer it to make it safe and reliable and make sure nothing’s going to go wrong, that tends to drive up the cost. And once you drive up the cost and the size – it’s a very difficult problem to solve, all of those different constraints. And then when you start to think about operational requirements for customers – say that someone wants to run a data gathering system offshore 24/7 for the next five years and never have a ship visit it – you have a whole other set of requirements that comes in that makes it really a difficult proposition.
