Floating crane vessel with an integrated hull and lifting installation
Crane and floating platform as one delivered unit
A floating crane vessel combines lifting machinery with a hull or pontoon and its working-deck, mooring and utility arrangements. The crane-barge examples below illustrate that integrated supply. Select the delivered vessel configuration for the intended lift and work site; a crane capacity label by itself does not identify it.
Integrated floating crane vessels, including crane barges, supplied with the hull or pontoon and installed lifting machinery as a complete floating unit. Pedestal-mounted offshore cranes as machines are on 7654; floating-crane upper superstructures on 7785 and active heave-compensation winch systems on 7818. Onshore harbor mobile cranes and bare cranes supplied without the floating platform are outside this vessel scope.

Retain the crane configuration and resolve the published boom-length difference
Damen’s IB 429 product page states lifting up to 400 tonnes and a 60 m boom. The linked Crane Barge 8025 sheet, identifying delivery in July 2013, instead lists main boom 62 m and prints SWL “400 ton @ 16 m”. Retain both boom lengths with their source positions and obtain the applicable crane drawing and load chart from Damen before specifying a lift; do not combine the headline capacity with an assumed reach or silently select one boom length. [1][2]
The sheet identifies a particular vessel and crane installation. The lift order should state the load, lifting radius, crane configuration and vessel condition against the supplier’s applicable operating documentation. The historical delivered-vessel sheet and the current product webpage do not establish a load chart for an unspecified new barge. [2][1]
02
Treat deck loading, water ballast and station keeping as separate vessel duties
The IB 429 sheet lists deck area and strength separately from crane performance, together with water-ballast capacity and the anchor-mooring arrangement. These fields describe different aspects of the floating platform. Specify the lifted load and working-deck cargo as separate load cases rather than treating deck strength as a crane rating. [2]
These catalogue values do not demonstrate a new vessel’s stability or permit an arbitrary concentrated deck load. Request the actual loading conditions, stability documentation, crane-foundation arrangement and mooring operating limits for the offered unit. Damen describes its crane barges as project-specific designs for sheltered-water and offshore work, so the intended work site belongs in the design brief. [2][3]

Anchor pattern, site conditions and supplied mooring equipment.
03
Define hook or grab work and the supporting craft in the delivery
THHI’s identified barge-mounted floating crane offering describes hook and grab operation and customization of barge size, power and control mode. Set the cargo attachment, handling duty and barge supply together; a bare crane or grab quotation is not the complete floating unit covered here. [4]
Damen describes turnkey packages that can add tugs, crew boats and pontoons to the IB 429 supply. Identify which craft and work equipment are included and how the floating crane will be moved and held at the site. An additional-support option does not establish that every delivered barge is self-propelled or includes the same support fleet. [1]
For the vessel handover, request the configuration drawing, applicable operating documentation and equipment list for the actual crane, hull, mooring and utility installation. The THHI offering identifies technical drawings and operation/service documents among its supplies; the scope still needs to be agreed for the specific unit. [4]

Buyer questions
Does Damen state the IB 429 boom length consistently?
Its product webpage states 60 m, while the linked delivered-vessel sheet states a 62 m main boom. The sheet separately prints SWL “400 ton @ 16 m”. Confirm the applicable drawing and load chart with Damen. [1][2]
Is the deck-strength figure the vessel’s lifting capacity?
The IB 429 sheet lists deck strength, crane performance and ballast as separate fields. Obtain the vessel-specific deck loading and lift documentation; deck strength alone is not a crane load chart. [2]
Sources and evidence scope
Sources checked 2026-10-18. Damen’s IB 429 webpage and delivered-vessel sheet, its crane-barge project scope, and THHI’s barge-mounted crane offering. Published figures apply to those configurations; no displacement, lifting capacity or stability calculation is inferred.
