Keel fin (custom-fabricated)
Marskeel
The range of combinations goes from a 400 lbs Stainless Steel fin with a 1,100 lbs bulb to a 7,650 lbs mild steel fin with a 61,200 lbs bulb. We have the ability to manufacture the keel fin from virtually any material that can be specified, or the North American equivalent, materials such as 316L to 2205 Duplex Stainless Steel to CHT 100 plate.
All the fabrications are constructed by Canadian Welding Bureau Certified Welders, CSA Standard W47.1 Division 3, for fabrication in Steel, Stainless Steel, and Aluminum, using MIG, TIG and Stick. We maintain a staff to offer the customer a complete weld joint design and engineering, refer to the MarsKeel Design Group section of the website for more information.
In addition to our in-house quality assurance we can offer complete NDT of all materials and welds, if required by the designer. Please see the section on our website, Quality Assurance, Testing Procedures for a more complete list of the testing and assurances available.
The design range of the fins has gone from very simple designs with side shells with a welded on top and bottom plate (made from CHT 100) to very complicate internal webbing (made for attachment of lifting cylinders) with multi part skins made from CNC pre-machined panels, all portions made from Weldox 900, Duplex 2205 SS, and 316L SS, then completely CNC machined if required.
