Ship history
IMO 9521033
Yno ZJ2012 was delivered on 15 November 2011. She is ULSTEIN-design number 50 from Ulstein Group.
The sister vessels, named initially 'Neptune Despina' and 'Neptune Larissa', are IMR vessels of the ULSTEIN SX130 design. The vessels were constructed for shipowner Neptune Offshore at the Zhejiang yard, China and were named in a joint ceremony on 26 October 2011.
Ulstein supplied design, detailed documentation and main equipment for these vessels, including main switchboards, bridge and control room consoles, ULSTEIN IAS® (integrated alarm and surveillance system), ULSTEIN COM® (communication and information), navigation equipment and ULSTEIN PMS (power management system).
The X-BOW®, combined with a diesel-electric propulsion system, ensures excellent performance with regard to fuel consumption, sea-keeping and speed.
At the time of delivery, Reef Subsea announced the signing of two five-year charter agreements for the two vessels. Therefore, the vessels changed names to 'Reef Larissa' and 'Reef Despina'. The name was later simplified to just Larissa.
2016: Golden Energy Offshore took over the management of the two vessels.
April 2021: Larissa was awarded several months of firm W2W work for Wintershall Noordzee AS, from April to September 2021.
October 2021: Larissa was sold to OceanPart Servicios Maritimos. The ship was reflagged under Brazil. The vessel was later renamed again to Parcel Dos Reis.
2025, September: OceanPact has secured a contract with Trident Energy for offshore decommissioning at Brazil’s Campos Basin, starting Q1 2026 and lasting up to three years. The project involves the removal of subsea infrastructure, onshore dismantling, and environmentally responsible disposal, with various OceanPact divisions handling engineering, surveys, and logistics.
