Tabung tertutup biasanya digunakan untuk pembinaan dan pembaikan platform minyak, jambatan jambatan dan struktur sokongan lain yang dibina di dalam atau di atas air. Cofferdams ini biasanya dikimpal struktur keluli, dengan komponen yang terdiri daripada timbunan lembaran, wales, dan pendakap silang. Struktur sedemikian biasanya dibongkar selepas kerja muktamad selesai. Bagi pembinaan empangan, dua tambakan biasanya dibina, satu hulu dan satu hilir empangan yang dicadangkan, selepas terowong pengalihan alternatif atau saluran telah disediakan untuk aliran sungai untuk memintas kawasan dasar empangan. Cofferdams ini biasanya empangan tambak konvensional dari kedua-dua bumi dan mengisi batu, tetapi cerucuk atau beberapa cerucuk lembaran juga boleh digunakan. Kebiasaannya, apabila selesai empangan dan struktur yang berkaitan, penahan hiliran dikeluarkan dan penumpang hulu dibanjiri apabila pelencongan ditutup dan takungan mula mengisi.
