Deployment and installation basket for multi leg Electrical and / or Optical Flying Leads.
Based on the use of reconfigured Ubas A, B or G ROV Baskets.
Two methods are available for deploying and installing EFL’s and OFL’s with three or more legs / tails / ends. Which method to use depends on the length each leg.
A basket that includes two or more compartments for arranging the legs is used in the cases where each leg is long enough for the ROV to connect each of them to the subsea structure while the other ends and connectors remains secured and parked in the basket parking receptacles.
In the cases where the legs are too short for each end to be pulled out and connected individually while the other ends and connectors are still located in the basket parking receptacles, one or two FLP Boxes are used.
Each FLP Box, Flying Lead Parking / Positioning Box, permit up to five legs / tails including connectors to be parked in it. The ROV retrieve the box from the basket and bring the box including flying lead legs over to the subsea location where one and one connector is then connected. It can be landed on hard or soft seabed, or on top of subsea structures.
The box can also be used as a local subsea parking structure for FL’s connectors during intervention or workover operations.
FLP Box weight in air 97kg, in seawater 50kg.
See Datasheet for further details on Multi Tail EFL& OFL.
Datasheet for the FLP Box is available on request.
Retrieval and pull-out of a FLP Box with two parked flying lead legs from a Ubas A Basket is shown in this Video link.
Deployment and installation basket for up to five Bundled Electrical and / or Optical Flying Leads.
Based on the use of reconfigured Ubas G, H or I ROV baskets. The basket arrangement includes two Flying Lead Parking / Positioning Boxes, FLP Boxes. Basket type depend on bundle length and diameter. Using the Ubas H basket, the bundle length may be several hundred meter long.
The EFL/OFL bundle arrangement is similar to an HFL which contains several hydraulic lines / hoses.
An EFL / OFL bundle contains two, three, four or five EFL’s and/or OFL’s that are bundled together with one or two layers of spiral guard. Each flying lead cable may also be provided with spiral guard. A stainless steel tension relief wire may also be included. A PEHD clamp assembly is included in each end of the bundle. The outer spiral guard(s) is located between these two clamp assemblies.
A Dynema fibre tension relief line is included in the bundle. Using this line in combination with a reinforcement sleeve and the outer spiral guard, pull-loop arrangement is included in each end of the bundle spiral guard.
Each FLP box includes up to five electrical and/or optical connector parking receptacles. A ROV releasable length adjustable holdback arrangement between the FLP Box and the bundle pull-loops ensures that pull-out loads are transferred into the bundle assembly including tension relief line during the ROV pull-out from the basket, and not into individual FL cables or parked connectors. During pull-out the FL tails between the pull-out loop the FLP box will be hanging in a catenary shape.
The bundle arrangement requires only one first end and one second end pull-out and connection operation. Furthermore, there will be only one bundle line that may require final ROV seabed positioning, permanently or temporarily stabilisation (e.g., Ubag T-Types), and if applicable, rock dumping.
FLP Box weight in air 105kg, in seawater 55kg.
ROV releasable Ustrap tie-down straps is provided for securement of the of the bundled section of the assembly. Individual EFL tails and the holdback arrangement is secured in strapping plates.
See Datasheets for details.

Purchase
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
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 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.
Ufist Products are only available together with other products, rental equipment or services provided by Udeco.
See datasheet for details on Ufist Ball and Ring Fist.
As an option the rental EFL / OFL baskets can be provided with one or several combined connector Parking Receptacle & Retrievable Protector.
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 remains 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.
