Survitec’s new boat launching davits


Engineered with its European-based partner the Survitec range includes different davit types suitable for liferafts, rescue boats and fast rescue craft. Designed and manufactured in Europe, to European standards, the davits have been created to withstand the harsh environments in which they operate.


Marine grade stainless steel is known for its resistance to corrosion, which is why


key elements have been made from the alloy, including the remote-control function, shackles, securing wires and cover plate. Further protection against corrosion is by way of a three-layer paint system that can adheres to Norway’s stringent NORSOK standards developed for the petroleum industry.


A grooved drum guides the fall into the correct position and packs it tightly within the drum as the fall is wound up and down during the lifting and lowering of the raft or boat. This ensures that the top layers of the fall wires do not force themselves into the lower layers, avoiding abrasion and possible bights of the wire, thus eliminating any jerking or snatching motions when the liferaft or rescue boat is lowered.


The davits are supplied as a fully tested and assembled unit, which can be installed in or out of drydock. Providing the pedestals have been installed and tested, a Survitec technician can assemble and commission the davit when the ship is in port, reducing the ship’s downtime and costs.


Propeller concept unveiled by Teignbridge


Global propulsion designer and manufacturer Teignbridge Propellers has launched its revolutionary new modular propeller. The unique propeller is manufactured in aluminium bronze and is modular in design. Each blade can be removed and replaced if necessary. Known as the ‘Clamp on Blade’ design (CoB) it allows the vessel owner to store spare blades on board and if damage occurs, replace the blades without going to dry dock.


In addition, large propellers can be boxed or packed into a container for ease of transportation. The world- wide patent is pending, but the UK patent was confirmed this month.


According to Mark Phare of Teignbridge Propellers, on many vessels a damaged blade can be replaced by ballasting the boat to get the top blade and hub clear of the water. He recommends that a buyer of the new propeller system purchase one or two spare blades with the prop and keep them onboard for emergencies.
