assalamualaikum wbt!
plet is an acronym for pipeline ends termination. in short, it's basically the end of your pipeline. there are several reasons why you need a plet and for this project x, we need this as to terminate the rigid pipeline and to connect it to our flexible flowlines. though it can normally connected using a flange to flange connection, due to operation needs, we need to install the plet to accommodate some of the piping arrangement to it. sounds complicated?
and now, if you have several pipeline that need to be terminate at a platform, the best way is for you to consider plem. pipeline end manifolds. to consider this, you need to ensure that the hydrocarbon properties for each of the fluids are rather the same. the function of the pipeline is also the same or else you might end up to have several plet or straight riser to rigid pipeline connection.
this is something that you need consider in your design. as usual, pictures below are pictures taken (in photojournalism or documentary mode) for plet installation. its can be considered a normal lifting though but you still need to ensure several things prior to the lift. :D
hence, enjoy!
and i'm still offshore. suddenly got hit by weather as supposed that we can complete installation of rigid riser yesterday. hopefully i can go back during this thursday boat run. with that, i would not be able to stand up to my promise. i'm sorry.
