Alarm Systems and Methods for Preventing Improper Lifting of Tubular Members

An audible alarm system for preventing damage from improper lifting of tubular members at a work site comprising:

• a) a casing running tool configured to engage and lift a tubular member;
• b) a single joint elevator configured to engage and lift a tubular member;
• c) an operator operatively connecting said casing running tool to said single joint elevator, wherein a weight of a tubular member is applied to said operator when said single joint elevator engages and lifts said tubular member, and wherein said operator is adapted to alternate between a first retracted position when said weight applied to said operator is less than a predetermined set-point corresponding to a lifting capacity of said single joint elevator, and a second extended position when said weight applied to said operator exceeds said predetermined set-point;
• d) a sensor for detecting when said operator is in said second extended position;
• and
• e) an audible device operatively engaged with said sensor, wherein said audible device is adapted to produce an audible alarm sound to alert personnel at said work site when said operator is in said second extended position.

A method for preventing damage during lifting of tubular members at a work site, the method comprising the steps of:

• a) providing an extendable operator that operatively connects a casing running tool to a single joint elevator, wherein said extendable operator is configured with a predetermined set-point corresponding to a lifting capacity of said single joint elevator;
• b) coupling said single joint elevator to a tubular member;
• c) initiating a lifting operation, wherein a weight of said tubular member is applied to said operator during said lifting operation;
• and
• d) setting an audible device to provide an audible alarm to alert personnel at said work site when said weight applied to said operator during said lifting operation exceeds said predetermined set-point.
