Subsea ROV-mounted hot water injection skid

摘要

A remotely operated vehicle mountable hot water injection skid comprises skid frame, one or more floats, a power interface, one or more subsea power transformers, one or more electrical power interfaces, one or more data communication interfaces, one or more heater skid telemetry systems, a predetermined set of integration equipment, a water collection and heating container, a pumping and circulation system, and a hot seawater circulation flying lead or spray wand which allows delivery of heated fluid directly to a subsea asset using heated seawater delivered through a common hydraulic hot stab or directly to via a pressurized spraying wand.

1. A remotely operated vehicle mountable hot water injection skid (1), comprising:
a. a skid frame (10); b. a float (18) disposed at least partially within the skid frame; c. a subsea power transformer (30) disposed at least partially within the skid frame; d. a power interface (11) disposed at least partially within the skid frame (1) and operatively in communication with the subsea power transformer (30); e. an electrical power interface (60) disposed at least partially within the skid frame, the electrical power interface operatively in communication with the subsea power transformer; f. a data communication interface (12) disposed at least partially within the skid frame; g. a heater skid telemetry system (20) disposed at least partially within the skid frame, the heater skid telemetry system operatively in communication with the subsea power transformer and the data communication interface; h. a predetermined set of integration equipment (25) disposed at least partially within the skid frame, the predetermined set of integration equipment operatively in communication with the subsea power transformer and the heater skid telemetry system (20); i. a water collection and heating container (40) disposed at least partially within the skid frame, the water collection and heating container (40) comprising:
i. an interior water chamber (43);ii. a water inlet (41) in fluid communication with the interior water chamber;iii. a water outlet (42) in fluid communication with the interior water chamber; andiv. a heating element (70) in fluid communication with the interior water chamber; j. a pumping and circulation system (50) disposed at least partially within the skid frame, the hydraulically-powered pumping and circulation system (50) in fluid communication with the water collection and heating container (40), the pumping and circulation system (50) operatively in communication with the subsea power transformer and the heater skid telemetry system (20).
