2014-T-AAE1_PERMIT-GR for TE Subcom
Our company has undertaken the issuance of survey and installation permits for the project Asia-Africa-Europe-1 (AAE-1) from TE Subcom, approaching all the relevant Greek authorities and taking into account any local particularities in the Greek landing site of AAE-1 System in Chania.
The Continent – Ile d’ Yeu Fiber Optic Cable, is a telecommunications cable system linking Ile d’ Yeu to the French Continent.
The Scope of Work included the installation of two HDPE conduits (125mm OD) crossing a highly environmentally sensitive area over a length of 260m, punching out at the high water-mark at the landing site in Ile d’Yeu, France. The installed conduits have been subsequently proved (minimum ID verification) and messenger lines have been installed throughout the entire length of each duct. The constructed conduits are intended to be used for the protection of the cable link at the shore end approach, since traditional trenching was not an option at this landing site due to environmental restrictions.
Very accurate HDD operations in order to avoid drilling fluid inadvertent release, as well as transportation of the HDD Rig to the Island on a landing craft which landed at the project area so that the Rig could be offloaded due to inter-island transportation restrictions, were some of this project’s particularities which were efficiently dealt with, resulting to a smooth and successful project execution.
We performed remedial protection works for Alcatel-Lucent, on the AMX-1 Submarine Fiber optic cable system at Segment 3.1 Fortaleza shore end. Remedial works included articulated pipe installation articulated pipe clamps installation and re-burial of cable.
Works have been successfully completed in a timely and safely manner.
We successfully completed the remedial protection works of the AMX-1 Cable System in the Challenging surf zone of Fortaleza, Brazil. The particular cable system has been prone to exposures due to migrating sediments on the seabed caused by strong surf and current conditions. This led to the Subsea Cable being left un- protected to external threat following its initial burial. We successfully mitigated this threat employing its Dive Supervisors with a Local Dive Team and Spreads permanently imported in Brazil, to successfully install Articulated Pipes and Rock Clamps to the exposed cable in water depths up to 20m.
We successfully completed a 3km Direct Shore end including Burial with its subsea SKAS Jet Trencher for the new Fiber Optic Cable PCCS connecting USA to the Caribbean. Water depths ranged from 0 to 25m with strong surf zones encountered however works were completed successfully in Jacksonville, Florida.
PSL-MT, a provider of subsea installations and marine works to the international oil and gas, telecommunications and power transmission industries, has successfully completed a subsea power cable installation in Newfoundland
The USD$14.5 million contract with Newfoundland Power Inc., which required PSL-MT to install 12km of subsea power cables spanning from Bell Island to Broad Cove, was delivered on time and within budget.
Over four days, the two 6km cable segments were laid and secured on the rocky seabed in water depths of up to 135 meters, in just 22 hours.
To achieve this, PSL-MT provided a complete turnkey solution, featuring cable transportation, route survey and engineering, installation, post-lay protection and burial, as well as termination and jointing works.
“The new cable system, which has an expected service life in excess of 40 years, is set to completely eradicate the repeated power outages,” said Byron Skaftouros, Projects & Development Director for PSL-MT. “With annual repairs to the previous power link to Bell Island hovering near USD$1 million, thousands spent in repairs will be saved. We are extremely pleased to have made it possible for the aging cables to be replaced efficiently, without disrupting supply of electricity to Bell Island. By drawing upon our deep experience in every facet of subsea cable installation, from establishing an optimum subsea route for new cables through to installation and burial, we made certain that every step of the programme was executed properly and completed on schedule.”
PSL-MT performed a turnkey marine route survey and route engineering. Once the route was established, data was forwarded to the cable manufacturer to produce the two 250ton, 25kV power cable segments and spares. Upon completion, they were transported from Greece to Newfoundland on company’s cable transportation vessel MV Trader.
In two weeks, PSL-MT converted a “deck barge of opportunity” into a vessel with dynamic positioning and cable-laying capability by equipping it with a custom-designed modular cable-laying spread and portable azimuth DP-1 thrusters. With the MV Trader transporting the cables, the team travelled on the installation barge to the site. After the barge passed a series of sea trials, the cables were loaded onto it, ready for installation.
Phase 1 of the operation, involved shore-end landing at Broad Cove, after landing and securing it, the cable was connected to a “dead man” anchor offshore to prepare for laying the north-south cable. Phase 2 began immediately thereafter, and was completed with the installation barge. While cable was laid on the surface, an ROV deployed from the barge monitored the cable’s touchdown point on the seabed to make certain it was laid uniformly along the optimum route.
After cutting, sealing and abandoning the cable on floats near the Bell Island shore-end approach, smaller boats continued pulling in the cable in shallow water, while carefully managing the cable bight on floats. Eventually, the shore waiting line was connected to the waiting cable, putting the landfall support team in direct contact to begin the final pulling phase. Upon cable landing at the termination point onshore Bell Island, divers used GPS to check that the route was accurate and successfully aligned with RPL coordinates from the survey.
They then removed the cable floats and commenced protection works. First, 1000m of protective articulated pipe cover was fitted on the cable, then the cable was clamped to the seabed and cement bags installed to stabilize it on the rocky seabed. Finally, divers used hand-jetting and air-lifting techniques to bury 150m of cable to 1.5m top of cable.
PSL-MT successfully completed a complicated 1.5km Direct Shore end including installation of mechanical protection and burial for the Scilly Islands Cable system connecting these remote islands to the UK with a re-cycled Fiber Optic Cable. This complicated project involved first recovering an Out Of Use Cable from the seabed and then relaying it from the UK to the Scilly Islands through a series of reefs and rock outcrops. Many anchoring points and careful planning of pull-in practices were employed to ensure the cable weaved through numerous rock outcrops and ensure it laid within sediment able to bury and protect the cable. Water depths ranged from 0 to 25m and works were completed successfully in St. Mary’s Island, Scilly, UK.
PSL-MT employed its UK Subsidiary for these works, while simultaneously working on the Scottish Highlands and Islands projects involving over 40 direct Shore End Subsea Cable Installations in only 3 months over the summer season of 2014.
The SAM-1 network is the largest fiber optics submarine system connecting the U.S. with Central and South America, with landing stations in Argentina, Brazil, Chile, Colombia, Ecuador, Guatemala, Peru, and the U.S., including Florida and Puerto Rico. MARITECH International S.A. has been awarded by TE Subcom and successfully implemented the SAM-1 Shore End Cable Installation and Protection works in Mancora site, Peru. The shore end works included the Direct Shore End Installation of 1150m of submarine fiber optic cable from the BMH to the 15m contour, installation of 175m of articulated pipes, beach burial to 3.0m burial depth and inshore burial from LWM to the 15m WD at 1.0m burial depth by conventional burial methodologies (Hand-Jet/Airlift).
Scottish Highlands & Islands project (SHI) is a project of submarine cable installation, including lay of over 250 miles of fiber optic cable across 20 separate seabed crossings between the Scottish Highlands and Islands. PSL-MT has been awarded by Orange Marine to implement the shallow water installation and protection works of the SHI system which included 38 separate shore end landings throughout the Scottish islands, a 3.5km link installation in the Hebrides, installation of 1760m of articulated pipes, application of other protection methods such as uraduct and concrete bags’ installation as well as inshore burial of approx. 20km of cable by SKAS jet sled and conventional methods (airlift/handjet) up to 30m WD.
PSL-MT has successfully completed its part of the project tasks both on time and on budget thus making a major step forward with the support of the most complex subsea cable operation ever undertaken in the UK waters.
The Pacific Caribbean Cable System (PCCS) undersea fiber optic cable project will significantly increase data transfer capacity in Latin America and the Caribbean with a 6,000km cable connecting Florida, the British Virgin Islands, Puerto Rico, Aruba, Curacao, Colombia, Panama and Ecuador. PSL-MT has been contracted by Alcatel-Lucent to perform the Separate Shore End Cable Installation and Protection works of the subject system in Cartagena, Colombia which included the Shore End Installation of approx. 7km of submarine fiber optic cable from the BMH to the 15m contour, installation of articulated pipes and inshore burial from LWM to the 15m WD at 1.5m burial depth by SKAS jet sled.
PSL-MT has successfully implemented on time and in line with the project requirements both the installation and the protection of the fiber optic cable by deploying its own specialized Cable Lay Barge MCB1 and SKAS IV burial spread supporting on its own part the boosting of Colombia’s capacity 50 times over its current one.
