The scale on the chart isn’t the best, its a larger area in person. Can’t say I’ve seen a strong southerly wind, but have seen easterly at 70+kts without an issue. Ballast draft tanker is essentially a car carrier based on sail area but you’ve got room to put out as much chain as you would like and theres a 99% chance it’s just you in the anchorage. ---

That’d be a subject for another thread but a car ship will start jacking around at about 25 kts of wind. In about 35 kts it’ll put the wind first on one side then the other, slowly working the anchor back. At 50 kts almost no chance the anchor will hold. Any forecast over 35 kts means getting underway. Not just the sail area, also house forward. ---

On board almost all merchant ships there are two bow hawse pipes, and therefore not situated at the centre of the bow, the vessel’s natural position when lying at one anchor becomes canted just opposite to the anchor. With the increase of the strength of wind or tide, the vessel anchored at one anchor starts to yaw about. The vessel starts falling off the wind or tide exposing the one side of bow more, than the other and drifting sideways until she is stopped by the cable tension. From the above, if we can think up an anchoring system with the cable running over the exact bow of the ship the yawing problem can be reduced. Patent applied. ![image](https://us1.discourse-cdn.com/flex016/uploads/gcaptain_maritime_forum/original/3X/1/9/1905d245dfb072906ade07742800136a8e54cb03.jpeg) _The path traced out by a starboard-anchored ship’s hawse._ The path traced out by a starboard-anchored vessel (exactly her starboard hawse) is shown in the above figure. This path has the configuration of “8”. The asymmetry of the halves is caused by off-centre positioning of the used hawse pipe. This asymmetry becomes larger with the hawse pipes situated more aft, closer to the extreme ship’s beam. ---

There were 6 Avondale 165M DWT tankers constructed of high tensile strength steel - Atigun Pass, Keystone Canyon, Brooks Range, Thompson Pass and 2 operated by Exxon. The Kenai, Tonsina and Prince William Sound were early 125M DWT double hull tankers that were built like battleships by Sun Ship Building. The Tonsina and Kenai ran for 30 plus years ---

We used to load product from foreign flag processors anchored off-shore in Alaska. Here’s a photo I took of the ship I was on from a Russian ship. ![image](https://us1.discourse-cdn.com/flex016/uploads/gcaptain_maritime_forum/original/3X/6/6/669d839b4843ddaf0949f19fe9423a96d156f84d.jpeg) Here’s the same Russian ship but photo is from our deck. ![image](https://us1.discourse-cdn.com/flex016/uploads/gcaptain_maritime_forum/original/3X/8/d/8d5524d84cbe224fbc0f94dfb31bddd72caa7bdb.jpeg) I don’t recall the location this ship was anchored, far enough off-shore there was no land in sight. I don’t have any photos but we did the same thing with American vessels, including the big trawlers. Not just the Gulf but the Bering Sea. EDIT: Actually I don’t think we ever did this except west of Kodiak so technically not in the Gulf. ---

Great photo! It will take some time to find them but I have photos of Snowbird at Marco being refitted for the wester Pacific tuna fishery. Also, if I can find them a couple of pictures of it in San Diego after a fire onboard. I have always wondered where the old girl ended up. ---

Instead use a DP as a state of the art position holding system. Could it be that the navy uses such a DP as an “anchoring” system. Can be programmed to follow the wind direction, nose in the wind at all times. What yaw? Afterall drilling rigs started with anchors and taut wires for position keeping which evolved to full DP systems. The only thing to add to present day ships are a set of stern thrusters, DP software and a few smaller items. Patent applied. The previous one was unfortunately refused… ---

Shuttle tankers that is even bigger than those entering Valdez are now DP-2 Class.

Many DP Drillships have only one anchor (Ctr.line fwrd): ![image](https://us1.discourse-cdn.com/flex016/uploads/gcaptain_maritime_forum/original/3X/7/9/79a2476f23bb31409ab004b95caaa4bb40c6babb.jpeg) This requires dispensation from both Flag state and Class, which is readily obtained for a ship with DP-3 Class. Seldom used, even in port. In Singapore I can only remember it used when removing/reinstalling thrusters to get alongside at shipyards. (New rigs built in Korea often made a stop at Singapore for modifications and/or installation of additional equipment) ---

Of course being a non-US Flag MMC holder, you wouldn’t be cognizant of this regulation- 46 CFR 15.812(f), Pilotage is normally required when operating within the confines of certain areas covered… if these were US Mariners aboard US Flag vessels, I would have to sy that it would not have occurred… ---
