The Zr.Ms. Holland, an OPV from the Ministerie van Defensie, entered the Royal IHC construction hall in Krimpen aan den IJssel last week as part of its midlife upgrade program. The transfer followed a multi-step sequence involving towing, float-on operations and final positioning inside the facility.

The movement began at IHC Kinderdijk, where the vessel was towed to the Waalhaven. At this location, the float-on operation was carried out using the submersible barge HEBO-SUB1. After completion of this phase, the ship was transported from the Waalhaven to IHC Krimpen, where the vessel was brought inside the hall with support from Mammoet.

The process also included a roll-off step during the vessel’s positioning inside the facility. According to the project team, planning will now continue for returning the vessel to the water next year, marking the next stage of the upgrade cycle.
