Page 30: Connectors
The Subsea Bottle Connectors Umbilical The umbilical connector carries power and communications between the subsea unit and topside unit. It is a wet-mateable subsea connector which is designed to be made and broken in wet conditions topside. It should not be disconnected subsea. The deck integration cable can be connected directly to this connector to test and configure the system before an umbilical or subsea whip is connected for deployment subsea. -
Page 31: Probes
The Subsea Bottle Probes Three probe connectors are fitted to the U41. These are wet-mateable subsea connectors which are designed to be made and broken in wet conditions topside. They should not be disconnected subsea. Only SENSU2 UW probes from Eddyfi are compatible with the probe connectors and no other connection should be made as damage to the instrument may occur. - Page 32 The Subsea Bottle 6. Do not disconnect the umbilical underwater. It is recommended that the umbilical connection to the bottle is taped up to prevent it being inadvertently disconnected. It is also recommended that the umbilical is left connected to the bottle, if possible, between dives.
