摘要： The present disclosure provides an improved design for a pull tube sleeved stress joint and associated pull tube for managing stresses on a catenary riser for a floating offshore structure. The pull tube sleeve stress joint includes at least one sleeve surrounding a length of the pull tube with an annular gap between the sleeve and pull tube and a link ring therebetween. For embodiments having a plurality of sleeves, a first sleeve can be spaced by an annular first gap from the pull tube and coupled thereto with a first ring between the pull tube and the first sleeve, and a second sleeve can be spaced by an annular second gap from the first sleeve and coupled thereto with a second ring between the first sleeve and the second sleeve. Both pull tube and sleeves can be made with regular pipe segments welded together with regular girth welds.

摘要： The disclosure provides a tension leg platform (“TLP”) with a plurality of buoyant pontoons suitable for highly disturbed seas that can expand the stability of the tension leg platform by extending at least one buoyant pontoon beyond an intersection of two pontoons. In at least one embodiment, the location of the column can be decoupled from the customary end of the pontoon. The tendons can be located at the ends of the pontoons extending beyond the intersection. In some embodiments, such as four-column TLPs, the pontoons can be extended orthogonally relative to an adjacent pontoon. The extending pontoon increases a buoyancy of the pontoon, increases a pitch stability of the TLP, and increases quayside stability. The extended pontoon can be structurally intersected with the adjacent pontoon to strengthen the extended pontoon and reduce the failure mode of such structure.
摘要翻译：本公开提供了一种具有适于高度扰动的海洋的多个浮力浮筒的张力腿平台（“TLP”），其可以通过将至少一个浮力浮筒延伸超过两个浮体的交叉点来扩展张力腿平台的稳定性。在至少一个实施例中，柱的位置可以与浮筒的常规端分离。腱可以位于延伸超过交叉点的浮筒的端部。在一些实施例中，例如四列TLP，浮筒可以相对于相邻的浮筒正交地延伸。延伸浮桥增加了浮筒的浮力，增加了TLP的桨距稳定性，并提高了岸边稳定性。延伸浮桥可以与相邻的浮桥结构相交，以加强延伸的浮桥，并减少这种结构的破坏模式。

摘要： The disclosure provides a system and method for locking and unlocking an extendable column to a deck. A deck-to-column connection assembly includes a pawl and shim used in a sequential de-ballasting and ballasting of the column to the deck that can easily lock and unlock the column with the deck. Generally, the locking method includes ballasting the column to insert a pawl between the column and the deck, de-ballasting the column to raise the column relative to the deck and create a vertical gap between the column and the deck, inserting a shim to fill the gap and secure the pawl in a deployed position, and further de-ballasting the column to raise the deck connected to the column. Generally, the unlocking method lowering the deck to float on water, de-ballasting the column to remove compressive stress on the shim, removing the shim, ballasting the column, and retracting the pawl.

摘要： The present disclosure provides a system and method for supporting a catenary riser coupled to an offshore platform system including a pull tube and a pull tube stress joint for girth weld stress reduction and improved fatigue performance. A pull tube sleeve is coupled around a welded connection of the pull tube. The sleeve has a larger inner diameter than an outer diameter of the pull tube to form an annular space therebetween, and a fill material is filled into the space between the sleeve and the pull tube. The fill material provides a supportive coupling between the sleeve and the pull tube. The sleeve, the pull tube, or both can have gripping surfaces formed in or on their surfaces to retain the fill material in the space. The sleeve can be formed from a plurality of portions and be welded, fastened, or otherwise coupled around the pull tube.

摘要： The present disclosure provides an improved design for a multi-sectional truss spar hull platform having a truss and a spar hull. One or more sections can be transported to a designated location and off-loaded into water from an available transport vessel. The truss includes a skirt tank at the upper end of truss that can be coupled to the lower end of the hull. The skirt tank can provide buoyancy during float-off and mating operations to the hull. The skirt tank is designed to allow the portion above the water to be coupled to the hull in a first orientation, the truss with the skirt tank rotated with the hull in the water to a second orientation to expose the previously underwater portion, and then the previously underwater portion can be coupled together above the water. The integral skirt tank will be flooded after the spar hull is up-ended.
