The Kongsberg MW‑SD350 is an electric split‑drum mooring winch designed for high‑capacity anchor and mooring line handling, featuring a 700 kN brake and 44 mm wire capability. As a Mooring Winch, it is normally installed on the forecastle, poop deck or offshore working deck aligned with the vessel's chain, mooring or towing leads. In that role, its primary purpose is to heave, veer, hold or control chain, rope or wire according to the listed duty. Windlasses, mooring winches, towing winches and capstans differ in line handling and operating duty, but all require dependable brakes, drives and foundations. Capacity: 350 kN. For exact ratings, dimensions, settings, capacities, materials and variant-specific limits, refer to the manufacturer documentation for the exact figure.

For marine equipment hardly any maker or authorised dealer will name a price while the vessel is unknown. With the vessel details, availability and price can be settled faster; without them we may have to ask first, which costs a few days. If you are not allowed to name the vessel, a photo of the rating plate is enough — attach it below or send it as a reply to our confirmation e-mail.
