Sailing from US West Coast Ports ( Portland) towards the Unimak Pass in the winters, the sea and the swell could be anywhere from the port bow-beam. There are always at least two storms in the vicinity. These have made it across the Pacific, so they are well developed and energetic.
Firstly, agree that pounding must be avoided at all costs by reduction of speed if necessary. That generates a large amount of email traffic with the charterers and owners who want to know ( from the plush offices in downtown somewhere) WTF you are not making charterparty speed of 14 knots?
There is little anything else one can do, except adjustment of course to find the heading that the ship rides most comfortably at. With 8m swells, there is nothing one can do about stresses; the ship has to take the punishment and survive.
Also there is not much choice sometimes regarding alteration of courses, especially when closing the Aleutian islands.
