摘要：
A light weight lifting tool (10) for lowering and retrieving subsea equipment to and from the sea bed is disclosed. The equipment includes an upper coupling part in the form of a connector spool piece (15) having at least one circumferential ring groove (16) for use in making engagement with the lifting tool (10). The lifting tool (10) includes a housing (1) designed to enclose and receive the connector spool piece (15). The lifting tool (10) further includes a number of latch segments (8) having at least one radially inwards directed projection (8′) designed for engagement with the at least one ring groove (16), and an activating device (6) arranged to bring the latch segments (8) in and out of engagement with the at least one ring groove (16) by operation of the activating device (6).
