MODULE HANDLING SYSTEM FOR RISERLESS LIGHT WELL INTERVENTION The module handling system (MHS) is specifically designed to deploy and retrieve advanced equipment to facilitate subsea well intervention work in a highly accurate, safe and reliable manner. Key pieces of offshore well intervention equipment include subsea intervention lubricators (SIL) and subsea Christmas trees. All safety-critical passive heave compensation systems are ATEX hazardous zone rated, sufficient to ensure the vessel motions remain accommodated for well intervention operations, with all MHS drives shut down in case of a potentially dangerous ESD situation. The MHS consists of an integrated steel tower construction, which supports the systems for handling of the subsea equipment. It is easy to work with thanks to an advanced control system and strategically placed operator positions. The safety-critical systems are designed not to have a single point of failure, which could lead to unsafe situations. The MHS is fully compliant with DNV-GL WIU-1 and Well- 1 classification for vessel-mounted systems associated with well intervention (DNV-GL OS-E101 Drilling Plant). The system is also designed in compliance with DNV-GL 2.22 Lifting Appliances. The operating principle is such that an SIL assembly can be stored fully assembled and tested on a pallet on the parking position, reducing the work to be carried out offshore. For the lateral support of the SIL assembly, a support structure with access platforms is installed on the pallet. When the SIL is brought above the moon pool, it is subsequently lowered through the splash zone and to the seabed. Four guide wires connected to the subsea asset prevent unwanted movement. In the vessel moon pool, guidance is provided by two cursors minimising uncontrolled motions. Two pod-line systems safely guide the SIL control umbilical and kill line to the seabed. The pod- and guide-line winches are provided with active heave compensation functionality to achieve a swift and safe landing as well as disconnection. MAIN OPERATIONS • well intervention with subsea intervention lubricator • installation and removal of subsea Christmas trees. KEY FEATURES • fully integrated and redundant control system • integrated hydraulic and nitrogen system • high level of system integration • DNV-GL classed and certified to WELL-1 and WIU-1 • DNV-GL OS-E101, Drilling ship & 2.22 Lifting appliance • suitable for dedicated purpose-built vessel or vessel of opportunity.
