A petroleum drilling, production, storage and offloading vessel having a hull, a main deck, an upper cylindrical side section extending downwardly from the main deck, an upper frustoconical side section, a cylindrical neck section, a lower ellipsoidal section that extends from the cylindrical neck section, and a fin-shaped appendage secured to a lower and an outer portion of the exterior of a bottom surface. The upper frustoconical side section located below the upper cylindrical side section and maintained to be above a water line for a transport depth and partially below the water line for an operational depth of the petroleum drilling, production, storage and offloading vessel.

An escape apparatus for a vessel includes a support frame that is configured to be installed at the vessel and that defines defining an exit opening, an escape door located at an inner side of the exit opening and configured to open and close the exit opening, where the escape door defines an accommodation space, a floater located in the accommodation space of the escape door and configured to be raised relative to the support frame, and an unlocking device configured to, based on being pushed by the raised floater, release coupling between the escape door and the support frame.

The present invention relates to a submerged-floating type water house. The house comprises: a first lower side part and a second lower side part formed symmetrically with respect to each other; a first upper side part and a second upper side part formed symmetrically and extending from the first lower side part and the second lower side part; and a front part and a rear part formed in front of and in back of the first lower side part and second lower side part and the first upper side part and second upper side part, thereby forming a rhombic-shaped body and floating in water.

A swim platform is built into a side of a boat, either the port or starboard side. The swim platform is raised and lowered by a mechanism that fits within the side wall of the boat beneath the gunnel. The swim platform is raised when the boat is underway to prevent water intrusion, provide safety, and reduce drag; while the swim platform is lowered, for example, when the boat is anchored for enjoyment of the boaters using the boat.
