MULTI-PURPOSE SUPPORT VESSEL / DP2

The Astrea is a DP-2 Multi-Purpose Support Vessel built for worldwide operations and specially designed for cable laying, protection and repairs as well as for ROV work and surveys. She is fitted with twin CP propellers, twin split rudders, bow and stern thrusters linked to a Kongsberg DP-2 system, which give her an excellent station keeping capability. Originally built in Norway in 1987 as a PSV, and fully refitted/renovated in Greece in 2008 under the highest DNV Class and Greek Flag Standards, she is now classed with ABS as a Special Purpose Vessel fully complying with the SPS Safety Code. She holds an extensive track record, on a variety of diverse projects ranging from cable laying and protection to FPSO installation works, and is being constantly kept up to date with new equipment and careful maintenance to ensure zero down-time and highest possible performance on her employments.
