Ufist – Ball Fist for Flying Lead Installation

Manual MQC make-up tool.

The Ufist system includes various types of ROV lifting and handling devices. Among other this includes ball fist and ring fists for flying lead installation.

Purchase

View Details

For HFL installation large ball fists (100mm dia.) with anti-slip strap are recommended.

For EFL / OFL installation small ball fists (65mm dia.) with are recommended.

The fists are fast to install and do not require extensive duct taping and / or tie wraps for the attachments.

Fist used for flying lead installation is delivered with a temporary shortening ring in order to reduce the risk for entanglement between fists, or fist and jumper / cable during pull out of the flying lead.

For increased fist buoyancy and for easy grabbing of the fists they can as an option be delivered with a bendable and buoyant 1” PE tube.

See datasheet for details on Ufist Ball and Ring Fist.

Combined Parking Receptacle and Protector

Manual MQC make-up tool.

As an option the rental EFL / OFL baskets can be provided with one or several combined connector Parking Receptacle & Retrievable Protector.

View Details

EFL/OFL rental baskets are provided with parking receptacles for the electrical and optical connectors. These are permanently attached to the baskets and secure  and protect the connector during basket transport, handling, deployment and landing on the seabed.    

In a case where a protector is needed on the connector during pull out of the EFL/OFL from the basket, and later for temporary placement on the seabed or on the subsea structure, a combined connector receptacle and protector is available. When the ROV retrieve the connector from the parking receptacle in the basket, part of the receptacle remain attached to the connector and act as a protector (mechanical + debris). The non-buoyant protector is removed by the ROV prior to connecting the connector. The protector does not include any metallic parts that may cause a possible galvanic reaction with the connector parts if the connector including protector is left temporarily unconnected on the seabed or subsea structure.
