Colombo Dockyard in Sri Lanka has secured a contract to build a cable-laying and repair vessel for Orange Marine France
The vessel is a modern, high-tech unit designed and equipped for subsea cable lay and repair operations with a focus on good seakeeping, excellent station keeping performance and low fuel consumption.
The vessel was designed by Vard Design in Norway and has an optimised hullform and bow shape, enabling the vessel to achieve high speeds and minimise its carbon footprint.
The vessel’s primary activities will be cable operations, including laying, repair and ROV inspection. The vessel is able to mobilise a power cable-lay spread to undertake subsea inter array cable laying.
The vessel is 100 m in length with a beam of 18.8 m and deadweight capacity of 1,800 tonnes. It can achieve a speed of 14.5 knots and has accommodation facilities for 76 people. The vessel has three cable tanks to carry fibre optic and power cables. One of the three tanks is fitted with a carousel.
The new vessel will be fitted with a diesel-electric propulsion plant consisting of four generator sets. Propulsion will be by two main azimuth propellers in the aft and two tunnel thrusters in the forward section of the vessel.
The vessel will be built to Bureau Veritas classification society standards and meet the regulatory requirements of the French flag. It is due to be delivered in early 2023.
