The conversion of one unusual specialist ship into another is now underway at Lloyd Werft in Bremerhaven, Germany, as planned, but completion has been delayed by a fortnight, according to the yard.

Tom Todd writes: Work on converting the 11,000dwt dock ship newbuilding Combi Dock IV (completed by LWB only last year) into the heavy-lift, deep-water oil exploration and offshore support vessel OIG Giant II got underway after her arrival on 10 August. Completion for Harren Partners’ new Offshore Installation Group (OIG) had originally been set for 15 September. LWB managing director Rüdiger Pallentin told The Motorship however that yard and owners had agreed to a two week delay to the end of September.

No reasons were given but Pallentin had said earlier of the original September 15th completion date: “It’s a tight deadline … and a sporting challenge in such a short time-frame, but we are used to that here”.

The 162.5m x 25.4m Combi Dock IV is one of a series of four heavy lift dock ship sisters built at LWB between 2007 and 2010 for the German/Danish company Combi Lift. One has already been converted into OIG Giant I and plans now are to convert the others.

OIG Giant II will boast not only a submersible and tiltable open stern ramp for floating in or out, but also a heli-pad and an additional 500 ton, six-deck accommodation extension to the forward superstructure built by neighbouring WST Weser Stahlbau. Her forward, heavy-lift cranes are being lengthened and a 7.8m x 7.4m moonpool installed along with six more generators on deck to cope with increased power needs.

OIG Giant II is also getting a DP system, which means the relocation of the forward bow thruster and the installation of two stern thrusters as well as rudder modifications. She will have two hydraulically retractable Azipod thrusters 3.3m below the hull with 3m diameter propellers and turning through 360°.
