Abstract: There is provided a method for loading or unloading a liquid cargo for a water-borne vehicle. An exemplary method comprises distributing liquid cargo to a first storage compartment of the water-borne vehicle to a first level. The exemplary method additionally comprises distributing liquid cargo to a second storage compartment of the water-borne vehicle to a second level different from the first level so that a natural period of the first storage compartment is separated relative to a natural period of the second storage compartment to reduce sloshing of the liquid cargo. An exemplary water-borne vehicle and method of producing hydrocarbons are also provided.

Abstract: A system for supporting multiple-well-site, offshore, hydrocarbon-bearing fields, each well-site has one or more wells. In general, the system first comprises a floating vessel that is relocatable from a first subsea well-site to a second subsea well-site. The system also comprises two separate systems: (1) an operations control system for providing subsea well-site operations such as power and communications; and (2) an intervention system for conducting intervention services to an individual subsea well such as workover services and maintenance services. The operations system may provide control to wells and other subsea equipment at either the first well-site or the second well-site, regardless of the location of the floating vessel. The intervention system may provide workover and/or maintenance to subsea equipment or individual wells at the well-site at which it is located.

Abstract: A fairing for elongated elements is disclosed for reducing current-induced stresses on the elongated element. The fairing is made as a stream-lined shaped body that has a nose portion in which the elongated element is accommodated and a tail portion. The body has a bearing connected to it to provide bearing engagement with the elongated element. A biasing device interconnected with the the bearing accommodates variations in the outer surface of the elongated element to maintain the fairing's longitudinal axis substantially parallel to the longitudinal axis of the elongated element as the fairing rotates around the elongated element. The fairing is particularly adapted for mounting on a marine drilling riser having flotation modules.
