Abstract
Watertight and thermally insulating tank built into the bearing structure of a ship, said tank comprising two successive watertightness barriers, one being a primary one in contact with the product contained in the tank and the other being a secondary one placed between the primary barrier and the bearing structure, at least one thermally insulating barrier being provided between the bearing structure and the secondary watertightness barrier and/or between the two watertightness barriers, each thermally insulating barrier consisting of a number of caissons (102) of roughly parallelepipedal overall shape, each caisson having a bottom panel (105) and a top panel (106) made of plywood, characterized in that the panels of each caisson are spaced apart by a number of spacer pieces (103) which consist of thin sheets of plywood, extending at right angles to said panels, each caisson being at least partially filled with blocks of foam (104), bonded over a substantial part of the height of each spacer piece, to prevent the spacer pieces from buckling under load.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
