Tanker into shuttle tanker conversion for J. Lauritzen

In September 2007 Remontowa S.A. signed conversion contract with Danish shipowner J. Lauritzen. The main task was to convert tanker vessel named Freja Pacific to shuttle tanker.
Vessel before conversion had DNV class with notation +1A1 Tanker for Oil, ESP, CSA-1, VCS-2, SPM, EO and featured the following main particulars: LOA = 183.24 m; Bm = 32.2 m; Hm = 18.2 m.

Engineering for conversion basing on owner’s specification and provided by owner input design from specialized contractors has been carried out by Remontowa S.A.
New loading facilities onboard are provided by Bow Loading System (BLS) consisting of loading equipment from APL. This equipment is connected to vessel's cargo manifold by new cargo pipeline DN400. BLS equipment is located in newly installed forward deckhouse and in modified forward stores.
During conversion the vessel's propulsion system has been significantly modified and upgraded.
Main propulsion has been changed to CPP type. Additionally new forward tunnel and azimuthing thrusters have been installed with 1720 kW and 1500 kW power rating respectively. These new thrusters are accommodated in the new purpose built compartment forward.
Aft of the vessel also tunnel thruster of 1355 kW and azimuthing thruster of 1500 kW have been installed in main ER, which has been extended in order to accommodate them.
New equipment as well as DP mode control system required it to add new power station, which consist of three new generator sets of 2708 kW, 690 V each. These generators and all required auxiliary equipment, including new main switchboards as well as new ECR, have been installed in new auxiliary engine room housing located on vessel aft, over the poop deck. All new auxiliary ER systems like cooling; FO; LO and others have been integrated into existing ones in main engine room, where extensive scope of modification works also have been carried out.
Vessel's control systems have also been extensively modified and upgraded. First of all new DP equipment K-Pos DP21 with associated systems of Artemis; RADius; DARPS; DGPS; Fleet 77 Bloom PMS; C-Joy and Fanbeam have been installed and integrated onboard.



During the conversion period some other vessel equipment have been upgraded and modified. New catwalk on main deck providing safe access from accommodation to vessel's bow and BLS decks have been installed. Ships offices in accommodation as well as wheelhouse have been completely rebuilt and upgraded. The vessel has received new radars; VHF/UHF and telephone/paging system. Existing vessel control and monitoring system has been renewed and integrated with cargo control. New CCTV and computer network have been installed through entire vessel. Vessel's exhaust gas boiler has been renewed to composite type one.
Additionally to conversion work extensive maintenance and drydock works have been performed including ballast tank treatment.
Conversion work included installation of new steel structures with weight of ca 500 tonnes and ca 100 km of cables and significant length of various diameter pipes.
All work onboard has been performed as planned in summer 2008 and supervised and approved by DNV, classing the vessel according to notation: +1A1, TANKER for OIL, ESP, CSA-1, VCS-2, SPM, EO, NAUTICUS (Operation) T-MON, DYNPOS, AUTR, BLS Northsea.
