Abstract
A remote operated underwater vehicle, ROV, is provided, where the ROV includes at least one extendible pair of tubulars supported on the ROV, the one tubular of the pair being movable longitudinally relative to the other tubular of the pair, for extending a combined reach of the tubulars; and at least one pump connected to the tubulars, the pump being operable for pumping or suctioning fluid through the pair.
Claims20
An underwater vehicle for performing an underwater pumping or suctioning operation, the underwater vehicle comprising:
- rigid tubing which comprises at least one extendible pair of tubulars supported on the underwater vehicle, the one tubular of the pair being movable longitudinally relative to the other tubular of the pair, for extending a combined reach of the tubulars;
- at least one pump coupled to the rigid tubing, the pump being operable for pumping or suctioning fluid through the pair of tubulars;
- and
- a motor operable for actuating the extendible pair.
An apparatus comprising:
- rigid tubing which comprises at least one extendible pair of tubulars to be supported in position under water, the one tubular of the pair being movable longitudinally relative to the other tubular of the pair, for extending a combined reach of the tubulars;
- a motor operable for actuating the extendible pair;
- and
- at least one pump to be coupled to the rigid tubing, the pump to be operable for pumping or suctioning fluid through the pair of tubulars.
