Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a visible light communication control device and an underwater work support system allowing an underwater worker to operate an underwater suspension and swing device while securing an enough distance between the underwater worker and an underwater-working machine.SOLUTION: A visible light communication control device 23 transmits operation packets from a transmission device 21 installed in a communication device 20 equipped by an underwater worker, to a receiving device 22 installed to an underwater suspension and swing device via visible light communication. The operation packets corresponding to operation information input to a water-proof microphone 26 attached to the communication device 20 are created and continued to be output to the transmission device 21 repeatedly for a predetermined time.SELECTED DRAWING: Figure 3 【課題】水中作業員と水中で作業を行う機械との離隔距離を十分に確保したうえで水中作業員による水中吊荷旋回装置の操作を可能にする。【解決手段】水中作業員が装備する通信機器２０に設けられた送信デバイス２１から、水中吊荷旋回装置に設けられた受信デバイス２２へ、可視光通信により操作パケットを送信させる制御装置２３であって、通信機器２０に設けられた防水マイク２６に入力された操作情報に対応する操作パケットを生成し、該操作パケットを、所定時間、繰返し送信デバイス２１へ出力し続ける。【選択図】図３
