Q1000 – Taiwan, Yunlin Offshore Wind Farm

Q1000 is a recognised and reliable trenching asset, with 1000 HP of installed power. Q1000 is an agile trencher capable of burying large export cables and interconnector cables down to 3m trench depths.

Q1000 was utilised on a wind farm project in its early stages of development. The OWF consisted of 80 wind turbines, each with a capacity of 8 MW, based on an inner array grid and export cable to the beach, approximately 272 km of total length. Pharos’ successfully trenched the array cables that connect each of the monopiles together throughout the windfarm. On this project Q1000 was operational for over 8,500 hours.

UTV400 – Canada to Alaska

UTV400 is capable of all aspects of cable maintenance, seabed survey and cable burial work at depths down to 2,500m with 400HP of installed power. Using high power, it is purpose designed to provide maximum jetting and thrust performance.

UTV400 was utilised on a long-term hire agreement undertaking telecommunication cable maintenance. The cable repairs took place from Canada, along to the West Coast of Alaska, close to the Arctic Circle. UTV400 worked successfully to promptly repair telecom cables, re-establishing vital communications. Maintaining consistent client communication was critical for daily activities due to the constraint of extreme weather conditions and a frozen sea during the winter months, making a rapid response crucial.

UTV1100 – Saudi Arabia, Red Sea

UTV1100, is a surface fed trencher optimised for shallow water operations. A pair of surface water pumps can deliver more than 800HP up to 14 bar and over 1000m³/hour dependent on nozzle configuration. Its compact design allows it to be mobilised on small and compact vessels.

UTV1100 performed shallow water trenching on over 60km of interconnector power cable for a multiple island infrastructure development project. UTV1100 achieved a successful burial campaign in very challenging seabed conditions. This project was located in a particularly environmentally sensitive area, which required the in-house design and manufacture of a unique Pharos silt mitigation solution which had to be integrated to UTV1100.

XLS 26 – Coast of France, Fecamp Offshore Wind Farm

XLS 26 is a highly flexible Work Class ROV system. It is the ultimate in hydraulic heavy duty Dual Construction and Survey Class ROV, designed and built to perform the most exacting operations in the harshest environments.

XLS 26 performed seabed monitoring and completed a successful jacket installation in challenging conditions on an offshore wind farm off the Coast of France. Pharos completed the project with zero hours of downtime. The 497 MW wind farm consisted of 71 turbines, generating electricity equivalent to power more than 416,000 homes.

CFE 500 – Germany, River Weser

CFE500 is a purpose-built subsea excavation system. The CFE500 has a configurable tilt frame housing, which allows the base unit to be tilted to 45° from vertical and assists with stability in high currents.

CFE500 was utilised to bury a live power cable section of 100m to a depth of 4m in the Estuary of the River Weser, Germany. For this project, the system was prepared and shipped within 5 days.

Cable Grab – Coast of Kent, London Array Offshore Wind Farm

The hydraulic cable grab is a versatile and capable cable recovery system with a 20,000kg Safe Working Load for recovery and deployment.

The cable grab was used on a landmark project for Pharos, completing the first ever diverless
export cable repair on the London Array Offshore Wind Farm. Assets for the handling of the large export cable did not exist in the market and standard grapnel operations were not possible due to nearby cable routes. Therefore, this project
required
pioneering solutions including the development of entirely new operational procedures. The Pharos team also converted a conventional telecoms cable ship to accommodate the loading, storage, lay, splicing and safe handling of the product.

Plough Build – Pharos HQ, Blyth

Pharos executed a full redesign to build the Sea Stallion II plough for a European client. The plough had no HPU or valve tanks which Pharos sourced from another plough and interfaced to the Sea Stallion II. Pharos completed a full overhaul including new cylinders, hoses, control system and repatriated a ROV HPU. This project improved the ploughs capability to allow for side loading of cable using the current bellmouth arrangement. The plough was delivered in three months and
Pharos supported the operation of the plough by providing highly experienced plough operators.

FAT Test (Personnel) – Client Workshop, Aix en Provence, Marseille

Pharos supported our client by providing personnel to witness a Factory Acceptance Test (FAT) of the Alpha 8 ROV. Our exceptional offshore personnel have the experience and knowledge to undertake auditing tasks to satisfy clients of the
assets’ operational performance.
