Onboard oil containment system

A winch reel assembly comprising:

• a) a reel that is rotatable and has a core;
• b) a motor;
• c) an inflatable flow line wound in multiple wound layers upon the reel, wherein the inflatable flow line has a first end and a second end, and wherein the first end is deployable from the reel;
• d) a gas delivery line that is wound on the reel and runs externally and concurrently along a length of the inflatable flow line wound on the reel for delivering pressurized gas to the wound layers of the inflatable flow line while wound on the reel, and wherein a weight of the inflatable flow line wound on the reel prevents inflation of the inflatable flow line until the inflatable flow line unwinds from the reel and is deployed from the reel;
• e) a valve positioned in the core of the reel through which pressurized gas is deliverable to the gas delivery line and to the entire length of inflatable flow line wound on the reel;
• f) a pneumatic system comprising a gas supply line and pneumatic supply, wherein the pneumatic system supplies pressurized gas via the gas supply line to the motor and also through the valve in the core of the reel to the gas delivery line;
• and
• g) wherein activation of the pneumatic system causes simultaneous powering of the reel through pressurized gas supplied to the motor, for enabling rotation of the reel for deployment of the inflatable flow line, while also supplying pressurized gas to the gas delivery line wound on the reel and to the wound layers of the inflatable flow line, for enabling inflation of the inflatable flow line as it unwinds from the reel.
