This was a adventure science fiction YA/MG novel that I read sometime in 2013 or 2014.
This is going to be super vague but I distinctly remember one plot point in the book. The group of characters were aboard a space station, a floating underwater station, or a in-orbit platform (like the helicarrier) that was built for science. I can't exactly remember what kind of station it was. Anyway, a bunch of survivors or random people had to come aboard due to some crisis. Then, due to this crisis, the station was losing power and was going to lose life support. I remember that they went in moderate detail to which modules of the facility were using power and still had power, etc and they realized that the entire science lab part was using too much energy. They jettisoned the Science module into the ocean or into space and this was not a decision that was made lightly, and there was discussion about doing it. They could jettison the module because the station was built to be modular. They removed the module with considerable difficulty and it damaged parts of the space station. After the module was jettisoned, they had enough power to keep surviving until their rescue arrived.
Can somebody please help me in figuring out what this is? Also, this wasn't the whole book, just the climax, but I remember that the station was a plot point and maybe the setting.
