Abstract
Provided herein is a system and method for installing subsea insulation on flowlines, connectors and other subsea equipment by a remotely operated vehicle. This system provides a mold designed and built to suit the parameters of the subsea item to be insulated. The mold is installed around the subsea item to be insulated and then injected with a liquid solution of insulation material. The liquid solution is then allowed to solidify, forming a gel molded insulation.
Claims23
A system for installing subsea insulation comprising:
- a remotely operated vehicle;
- a subsea gel insulation mold installed subsea on an item to be insulated by the remotely operated vehicle;
- and
- a subsea gel injection system capable of pumping insulation solution and catalyst through a mixing nozzle into the installed subsea gel insulation mold forming insulation on the item to be insulated between the item to be insulated and the mold;
- wherein insulation solution and catalyst are stored in separate reservoirs.
A method for installing subsea insulation comprising:
- using a remotely operated vehicle to install subsea a subsea gel insulation mold on an item to be insulated;
- and
- pumping insulation solution and catalyst through a mixing nozzle into the installed subsea gel insulation mold forming insulation on the item to be insulated between the item to be insulated and the mold.
A method for installing subsea insulation on subsea equipment comprising:
- a) providing subsea a plurality of subsea gel insulation molds;
- b) using a remotely operated vehicle subsea to grab one of the plurality of subsea gel insulation molds;
- c) using the remotely operated vehicle subsea to install one of the plurality of subsea gel insulation molds on an item to be insulated;
- d) pumping insulation solution and catalyst through a mixing nozzle subsea into one of the plurality of subsea gel insulation molds by a subsea gel injection system forming insulation on the item to be insulated between the item to be insulated and the mold;
- and
- e) repeating steps b-d until the plurality of subsea gel insulation molds are insulated.
