Reef Larissa was delivered to Reef Subsea on the 3rd of February 2012 and underwent an enhancement campaign to better answer Oil & Gas and Renewable Cable industry’s needs. She commenced operations early May 2012. She is the sister ship to Reef Despina and both vessels have been bareboat chartered for five years from Neptune Offshore AS.

Both vessels are newly-built DP2 IMR and Subsea Construction vessels. Designed with the Ulstein X-Bow, they have a faster transit speed in head seas, and enjoy reduced fuel consumption. The design also provides several advantages in the foreship and on the working decks making the vessels more environmentally and work friendly (read more in foot note).

Designed for worldwide and deepwater services, they are equipped with 150t SWL crane with active heave compensation, an enclosed ROV hangar with integrated LARS for the deployment of Work Class ROVs on both sides of the vessel, a large moonpool and up to 844m² of working deck. The 150t crane is able to work in over 2000m water depth and, with the Reef Subsea’s WROVs, the vessels will be able to operate in water depths up to 3000m.

Vessels are classed with Det Norske Veritas, including class notations CLEAN DESIGN and Green Passport, comfort class COMF-V(3) and Ice Class ICE-C. They have a diesel electric power plant with azimuthing thrusters, resulting in an ERN rating of 99.99.97 and IMO DP Class 2 compliance.
