Harald B comprises accommodation modules, safety facilities, and operational support systems such as water treatment, power distribution, and living utilities. It is structurally linked to Harald A via bridging, enabling easy personnel transfer and shared use of service systems. It houses sleeping quarters, mess and recreation spaces, and emergency systems. Power and utilities may be routed from the processing platform or generated locally for accommodations. The platform connects into shared export and control networks that serve the Harald complex and coordinate with regional hubs like Tyra, making it integral to sustained offshore operations.
