Teliri
MISSION: telecom cable laying and associated trenching operations, telecom cable maintenance and ROV support.
Teliri is a cable ship for the laying and repair of under water cables. Electric generation is by 2 Wartsila WN 16V25 3,680 kW + 1 Wartsila WN 12V25 2,768 kW feeding: 2 LIPS steerable thrusters with fixed pitch propeller 2,200 kW each, 1 LIPS steerable retractable thruster with fixed pitch propeller in nozzle 2,200 kW, 2 bow LIPS tunnel CP propeller thrusters 450 kW each, laying machines and vessel general services.
Teliri is equipped with a Dynamic Positioning System Kongsberg SIMRAD ADP 702 thanks to which the ship can navigate automatically over a pre-established laying route.
Accommodation up to 68 crew, technicals and contractor personnel.
Antonio Meucci
MISSION: Submarine tecom cable maintenance and ROV support
The CS “ANTONIO MEUCCI” incorporates a 6300 KW main propulsion system, supplemented with two thrusters that provide effective and economical DP station‐keeping abilities under severe weather and sea conditions. The vessel has three cable tanks capable of carrying 2600 tons of cable. The vessel carries a full suite of fiber optic repair equipment and kits. The vessel is designed to handle both festoon and repeated cable systems. Being a traditional purpose‐designed cable ship, the “ANTONIO MEUCCI” conducts cable repairs over the bow with the use of two 3m‐cable drum engines. Cable lays are conducted over the stern with a 12‐wheel pair linear cable engine. For all cable storage and laying operations, the bending radius of the fiber optic cable is respected. The tank cones, bow and stern sheaves and the cable drums have diameters equal or greater than 3 m.
Urbano Monti
MISSION: marine surveys of new submarine cable routes and marine activities linked to submarine cables projects.
The ship built in 2007 as a multi-purpose support vessel has been equipped with state-of-the art equipment for marine surveys: multi-beams echo sounder, side scan sonar, ultra shore base line... Urbano Monti is a perfect complement to existing installation and maintenance cable ships belonging to the Orange group fleet and will enable to provide better services to the customers requiring not only installation services, but more comprehensive turnkey solutions that include also desk top studies, marine surveys as well as any other ancillary activities. The ship has been subject a major refit and conversion, renaming and change of Flag in order to be fully operational and capable to work all around the world.
Catania Cable Depot
MISSION: storage of spare plant for telecommunication submarine cable systems included in the MECMA agreement, training center and Elettra Tlc spa base port.
The Depot, situated in Catania port, is strategic in performing marine activities in the Mediterranean Sea:
one berthing point 90 m length and 7 m water depth at the root of the “Molo di Mezzogiorno”;
about 4.000 m2 of open space available;
a warehouse over three floors, each 2.700 m3, is used as customs depot, according to EEC regulations.
The ground floor includes: warehouse for the storage of repeaters, kits, equalizers and testing room.
The first floor includes: 10 tanks with a capacity of more than 5,000 m3.
The second floor includes: two fixed 6 WP linear Cable Engines for moving cables to/from ships and to/from cable tanks, two portable 2 WP LCE
ROV and Plough are stored within depot area for housing and maintenance when not on board Elettra’s ships.
ROV Phoenix II
The Phoenix II Remotely Operated Vehicle (ROV) is a reliable maintenance system, capable of post-lay inspection, burial cable, cutting and retrieval and other required underwater manipulation tasks up to 2,000 m w.d. The system consists of 125 horsepower ROV, steel armoured umbilical cable, topside support systems (including crane handling system, hydraulic power unit, diesel electric generator, navigation system, Marisat Communications link and operations and maintenance vans). Phoenix II is outfitted with a state-of-the-art Innovatum Ultra cable location and tracking system to enable the ROV to locate and track cable during PLIB and cable maintenance activities. The Ultra system employs four combination gradiometers and triaxal magnetometer sensors with HP 382 computer, high resolution graphics, and data storage.
1 – RSI 5-function manipulator
speed from 50 to 400 m/h
Rov Canyon ST208
The system produces 200 shaft horsepower. Offering both “free fly” and “tracked” modes of operations using unique retractable track modules, the system maximizes production in varying soil and bottom conditions. An advanced composite “bagpipe” style burial system with variable depth compatibility provides optimum burial performance in soil conditions up to 45 kPa. The vehicle is suitable for the following tasks:
- - Cable and flowline burial
- - Detection and tracking of surface-laid and buried cable
- - Cable burial depth determination and logging
- - Auto-follow cable tracking
- - Manipulation of cable product using cutters, grippers and surface recovery lines
- - Debris clearance
Max forward (tracked) 3.3 knots
Taurus Plough System
The Plough System is a well proven, high quality burial plough, manufactured by Soil Machine Dynamics Ltd. It is operated and maintained by Elettra Tlc spa and normally is supported by one of the Elettra’s cableships (C/S Teliri or Certamen). Specification Burial system: minimum pull, passive blade temporarily lifting a soil wedge for trenchless burial with minimum soil disturbance and thus best cable protection. Operation: pulled by tow rope from surface vessel. Burial depth: maximum possible cutting depth to underside of cable 1.500 mm in favourable conditions.
Repeaters up to 380 mm dia.
