The quarter turn bucket system of the present disclosure provides a compact ROV-operated valve bucket with Open/Shut indicator for a quarter turn valve. The device uses a drive lever and pivoted arm with a slide channel to reduce the travel for the 90° sweep. The system of the present disclosure allows a standard-sized bucket to be converted to a similarly-sized quarter turn indicator bucket capable of fitting into a ROV panel bucket mounting cutout. The system may further include a purpose built sweep window.

QUARTER TURN BUCKET SYSTEM
This section is intended to introduce the reader to various aspects of art that may be related to various aspects of the presently described embodiments. This discussion is believed to be helpful in providing the reader with background information to facilitate a better understanding of the various aspects of the described embodiments. Accordingly, it should be understood that these statements are to be read in this light and not as admissions of prior art.
 Remotely operated vehicle (ROV) panel buckets are designed to be panel mounted to allow a torque tool to interface with subsea equipment, including valves. Quarter turn (also known as 1/4 turn or 0.25 turn or 90-degree) subsea valves may be used on subsea trees and/or tree conversions and tubing head spools. However, ROV panel buckets offered by quarter turn valve manufacturers may be larger than desired. Existing ROV panels may have mounting cutouts to accommodate a standard bucket size, and therefore it may not be optimal, practical, or even possible to bolt on or otherwise accommodate a larger-than- standard bucket. There may be insufficient room to place a large bucket on a tight ROV panel at all. Further, large buckets will not nest together as closely as standard buckets. This issue can become critical when trying to add or maximize downhole functions (i.e. the number of valves) on a tree spool body, for example. In addition, if the buckets are too large to nest straight in front of the valves on an ROV panel, an offset (instead of inline) drive rod may be required to connect bucket to valve.
