In a chain table for connecting mooring legs to a turret which is rotatably supported on a vessel, with the chain table having a central portion arranged and designed for securement to said turret with an outwardly extending member connected to said central portion, characterized by an improvement wherein,

• said outwardly extending member angles downwardly from said central portion, and
• said outwardly extending member includes upper and lower flanges each of which extend downwardly from said ring about the entire periphery of said ring.

A method for installing anchor legs of a turret moored vessel comprising the steps of,

• while said vessel is in port,
• connecting a turret to a chain table with a central ring and outwardly extending upper and lower flanges, with said upper and lower flanges defining a peripheral groove about said central ring, said groove being arranged and designed to accept coupler members, and
• forming holes to define hole sets through said upper and lower flanges about the periphery of said chain table according to an anchor leg pattern for said vessel.

A method for installing anchor legs of a turret moored vessel according to an anchor leg pattern at a mooring site comprising the steps of,

• connecting a turret to a chain table, and connecting vessel end portions of anchor legs to said chain table corresponding to each leg of said anchor leg pattern while said vessel is in port,
• installing at a mooring site a seabed portion of anchor legs according to said anchor leg pattern, and
• connecting each vessel end portion to each corresponding seabed anchor leg portion to establish said anchor leg pattern for said vessel, when said vessel arrives at said mooring site.
