Rapp Hydema to Deliver ROV Moon Pool System

press release
Thursday, May 03, 2012

Ezra Marine Services awards Rapp Hydema contract for delivery of next generation ROV moon pool handling systems on vessel CONSTELLATION. 

 

The contract covers the delivery of two complete ROV Moon Pool handling systems for Ezra`s new build vessel Constellation. The systems to be supplied by Rapp are the latest generation of ROV MP handling systems designed for Work Class ROV operations down to 4000 meters in harsh weather. All winches are fully electric and each system has full redundancy and active heave compensation (AHC) for optimum operational safety.
 

Rapp's ROV Moon Pool Handling Systems utilize a subsea snubber that is launched beneath the vessels keel line. This design secures a softer latching of the TMS and secures a safer launch and recovery in harsh weather. The advanced Pentagon control system from Rapp has both auto matic launch and recovery modes. In automatic mode all of the winches involved in the operation are automatically controlled and synchronized in sequences by the PLC control system.  This feature allows for safe operation by a single operator.
 

An air bubble system is used in each Moon Pool.  This starts automatically and is designed to kill generated wave energy in the Moon Pool while the ROV package is lifted between the keel line and the splash zone. In addition to delivery of the ROV Moon Pool Handling Systems the contract covers design and partial delivery of ROV Moon Pool Hatches, ROV Moon Pool Rails (horizontal and vertical) and the ROV Skidding Pallet. Rapp Hydema will deliver the ROV Moon Pool Handling Systems in several phases to meet EZRA`s new build program for the Constellation vessel. Final delivery from Rapp Hydema is scheduled to take place in the First quarter of 2013.
