UH has spent the past year engaging clients to understand their diving daughtercraft operational and equipment requirements, and to develop a purpose-built vessel with a fully integrated dive system.
Diving daughtercraft systems are used in diving operations where the conventional diving DSV is not able to position itself close enough to an FPSO or offshore platform. The daughtercraft is fitted with surface-supplied diving systems capable of supporting nitrox and/or air diving operations, and is assisted by an additional support craft to transfer personnel and supplies during the operations. The mother vessel, barge, or platform is outfitted with davits for the daughtercraft and support craft, along with support equipment, including the decompression chamber, gas storage, and compressors.
Currently two designs of the purpose-designed diving daughtercraft are available: the 14-m (46-ft), eight-man HYDRACraft 1400 system, and the 15-m (49-ft), 10-man HYDRACraft 1500 system.
