Mooring arrengemet for accommodation barge

[amamini]

Hi,
I have a problem to select a suitable mooring system for an accommodation barge with following data:

Type of vessle : Accommodation barge
Dimension : 80 * 23* 5 m
Draught : 3.5 m
Place of work: Persian Gulf
Sea condision: 6 B-Force

For your information accordig to similar ship's data, we need 8 anchor each with 8 (ton) that seems over design.

Can you help me to find a good reference to solve this problem?

Thank you so much for your attention.

Best regards
Ahmad

How deep is the water - a pylon at each corner may be an option?
