Deck machinery comprises a Rolls-Royce hydraulic double drum escort winch and one hydraulic vertical anchor windlass at the bow. The escort winch is spooled with a high-performance synthetic towline on each drum. In addition, a towing hook is provided on aft deck. A dry and heated rope store is arranged under the winch with convenient and safe access from the forecastle deck and from the lower accommodation deck. An 18t Palfinger hydraulic knuckle boom marine crane is fitted on aft deck with 14m outreach.
