Abstract
A relatively permanent anchoring arrangement for a decommissioned tanker which is connected to an undersea flexible transfer hose, uses a spreader beam suspended under the tanker by a plurality of mooring hawsers which are guided on the hull of the tanker. A support column structure having a vertical axis is suspended from and supported by the spreader beam. The support column structure comprises a diver's chamber which includes a massive peripheral bearing which enables relative rotary movement between the diver's chamber and the support column. The diver's chamber is anchored and fastened using a plurality of anchor chains. The diver's chamber can be evacuated and made dry for a diver to enter for purposes of bearing inspection maintenance. A fluid proof rotary joint housed in the diver's chamber is provided for connecting an undersea flexible transfer hose to a rigid transfer tube emerging from the tanker at the bottom thereof. Anchoring in high seas is effective by this arrangement.
