Abstract: An intervention system and method for control of seabed equipment, including a control umbilical connected to a support vessel or rig via a surface winch; a tether connected to underwater seabed equipment; and an umbilical management system unit coupled between the tether and the control umbilical to couple the support vessel or rig to the seabed equipment. The control umbilical and the tether via the umbilical management system unit provide a communications channel for communicating media, including data, electrical power, hydraulic power and/or chemical treatment fluid, from the support vessel or rig to the seabed equipment. The umbilical management system unit allows for easy deployment and management of the control umbilical and tether and can reel in or pay out the tether and/or the control umbilical under remote control or autonomously.

Abstract: A subsea well service system and method are presented for use with an subsea pump capable of flushing the well intervention lubricator of an underwater hydrocarbons production facility. The system essentially includes at least one pump placed at a subsea location in proximity to the well intervention lubricator, and at least one fluid reservoir connected to the pump.

Abstract: A technique enables subsea intervention operations in which a compliant guide is deployed for connection with a subsea installation. A tool is provided to engage a lower end of the compliant guide in a manner that enables selective movement of the lower end between desired positions. For example, the tool may comprise a displacement mechanism that can be actuated to move the lower end of the compliant guide between an engaged position with the subsea installation and a remote parked position relative to the subsea installation.

Abstract: Subsea apparatus and a method for sampling and analysing fluid from a subsea fluid flowline proximate a subsea well is provided, wherein the apparatus comprises at least one housing located in close proximity to said subsea fluid flowline; at least one fluid sampling device located in the housing in fluid communication with a said subsea fluid flowline for obtaining a sample of fluid from the subsea fluid flowline; at least one fluid processing apparatus located in the housing in fluid communication with said subsea fluid flowline for receiving and processing a portion of the fluid flowing through said fluid flowline or in fluid communication with the fluid sampling device, for processing the sample of fluid obtained from the subsea fluid flowline for analysis, while keeping the sample of fluid at subsea conditions; a fluid analysis device located in the housing, the fluid analysis device being in fluid communication with the fluid processing device and/or with the fluid sampling device, the fluid analysis de
