Light well intervention umbilical and flying lead management system and related methods

A method for providing control and well kill capability during a subsea light well intervention, the method comprising the steps of:

• connecting a sea-bound end of an umbilical line to a tether management assembly, the tether management assembly including a connector for operably coupling a crossover line to the sea-bound end of the umbilical line, and including a flying lead spool assembly carrying a flying lead operably coupled with the crossover line;
• running the umbilical line from an umbilical spool assembly located on a vessel, the umbilical spool assembly carrying the umbilical line;
• connecting an end of the flying lead to an emergency disconnect package connector located on an emergency disconnect package of a subsea well, paying out a sufficient amount of the flying lead to reach the emergency disconnect package connector located on the emergency disconnect package utilizing a remote operated vehicle;
• landing the tether management assembly at a seabed location substantially spaced apart from a location of the subsea well;
• and
• running a wireline from the vessel through a pressure control head connected to the emergency disconnect package of the subsea well, wherein the umbilical line at a location where the umbilical line extends from the vessel is substantially spaced apart from the wireline at a location where the wireline extends from the vessel.

A system for providing control and well kill capability during a subsea light well intervention, the system comprising:

• a tether management assembly landed at a seabed location substantially spaced apart from a location of a subsea well, the tether management assembly comprising a connector for operably coupling a crossover line to a sea-bound end of an umbilical line, a flying lead operably coupled with the crossover line and adapted to connect to an emergency disconnect package of a well control package for the subsea well, and a flying lead spool assembly for deploying the flying lead;
• an umbilical spool assembly located on a vessel, the umbilical spool assembly configured to deploy and support the weight of the umbilical line and the tether management assembly during deployment thereof when connected thereto;
• the umbilical line extending between the tether management assembly landed at the seabed location and the umbilical spool located on the vessel;
• and
• a wireline extending from the vessel through a pressure control head connected to the emergency disconnect package of the well control package for the subsea well, wherein the umbilical line at a location where the umbilical line extends from the vessel is substantially spaced apart from the wireline at a location where the wireline extends from the vessel.

A system for providing control and well kill capability during a subsea light well intervention, the system comprising:

• a tether management assembly landed at a seabed location substantially spaced apart from a location of a subsea well, the tether management assembly comprising a jumper adapted to connect to a well control package connector located on a well control package for the subsea well, a jumper spool assembly for deploying the jumper, and a connector for operably coupling a sea-bound end of an umbilical line to the jumper;
• an umbilical spool assembly located on a vessel and including an umbilical spool, the umbilical spool assembly configured to deploy the umbilical line;
• the umbilical line configured to connect between the tether management assembly when landed at the seabed location and the umbilical spool when located on the vessel;
• and
• a wireline extending from the vessel through a pressure control head connected to the well control package for the subsea well, wherein the umbilical line at a location where the umbilical line extends from the vessel is substantially spaced apart from the wireline at a location where the wireline extends from the vessel.
