    Abstract: A closure is shown for an equipment sub. A closure door is carried by a sub body and movable thereto between open and closed positions for providing access to a pressure vessel. Various improvements are disclosed including a new mechanism for positioning wedge shaped arcuate segments between the door and the sub body, a retainer mechanism for guiding movement of cross bars, a split hinge adjustment mechanism for adjusting planarity and concentricity between the closure door and the sub body, an increased annular wall body thickness region surrounding the sealing surface for reducing warpage during welding, a pressure lock rod member which also engages a combination of cross bars and a crank for driving the cross bars, and a pry bar that can facilitate better manually operated leveraging of the closure door.

    Abstract: A marine vessel, and a system and method of using the marine vessel, to facilitate the introduction of bulk liquid commodities, such as LNG, into the established and extensive worldwide intermodal transportation system, which is based on containerized shipments. The marine vessel is a specialized vessel, of either ship or barge form, that is capable of holding a large number of ISO-sized intermodal LNG tanks and is configured so as to have at one and the same time characteristics of both a tanker vessel (e.g., a gas carrier) and a container vessel. The intermodal LNG tanks connect to a piping system of the marine vessel and are thereby interconnected in such a manner that allows the interconnected intermodal LNG tanks to behave as if they constitute a typical LNG vessel bulk liquid tank to facilitate efficient loading at a typical marine LNG terminal The containerized intermodal LNG tanks are capable of discharging liquids to a marine terminal as if in a bulk mode, or of being disconnected from the common interconnection system to allow lift-off discharge of the intermodal LNG tanks at a typical cargo container port so that the intermodal LNG tanks can enter the existing intermodal transportation system for further distribution to the end user by other marine vessels, over-the-road truck, or by rail.

    Abstract: A catalytic tank heater includes a catalytic heating element supported on an LPG tank by a support structure that holds the element in a position facing the tank. Vapor from the tank is provided as fuel to the heating element, and is regulated to increase heat output as tank pressure drops. The heating element is internally separated into a pilot heater and a main heater, with respective separate fuel inlets. The pilot heater remains in continual operation, but the main heater is operated only while tank pressure is below a threshold. Operation of the pilot heater keeps a portion of the catalyst hot, so that, when tank pressure drops below the threshold, and fuel is supplied to the main heater, catalytic combustion quickly expands from the area surrounding the pilot heater to the remainder of the catalyst.

    Abstract translation: 催化罐加热器包括通过支撑结构支撑在LPG罐上的催化加热元件,该支撑结构将元件保持在面向油箱的位置。 来自罐的蒸汽作为加热元件的燃料提供,并且随着罐压力下降而被调节以增加热量输出。 加热元件在内部分为先导加热器和主加热器,分别具有各自的燃料入口。 先导加热器保持连续运行,但主加热器仅在油箱压力低于阀值时运行。 先导式加热器的操作使催化剂的一部分变热,使得当罐压降低于阈值时,燃料被供应到主加热器,催化燃烧从先导加热器周围的区域迅速膨胀到催化剂的其余部分 。
