Most often, hangars are installed as extended beyond the platform outline to enable automatic lowering of equipment into the depths of the sea. Remote control of robots is carried out from the control room level, separated from the hangar itself due to safety regulations.
The complete hangar equipment, apart from the robot itself, also includes a winch, pulleys, slings, and a hydraulically opening hatch. All these elements had to be adapted to the newly designed structure and installed without collisions on the platform itself. All these tasks were undertaken by the NAVIC team, which, in full cooperation with Oceaneering, designed the ROV hangar and participated in the manufacturing process and commissioning at OneCo, the company responsible for manufacturing the finished product and delivering it to the platform.
All design work was verified and approved by DNV GL, which means that all design requirements for this type of structure were met, including the requirements resulting from dynamic and fatigue loads.
