We performed some complex tasks with Chockfast products on vessels under repair.

On NB801 TSHD Albatros build by MTG Dolphin Yard both stern tubes, two propulsion and one auxiliary reduction gears were mounted as per approved technology with Chockfast Orange and Phillibond Orange as a materials. On NB901 Grab hopper dredger again in MTG Dolphin Yard both stern tubes were fitted on Chockfast Orange. Both projects were submitted to the Yard, Class and Owners without remarks.

Additional one engine Stork 9TM410 and one engine MAN B&W 6S26MC were realigned and new chocks were casted. Both engines were secured on the new chocks with all the bolts tightened as per approved new calculations from the Class and submitted to the owners without remarks and with perfect crankshaft deflection.

Chockfast is an epoxy based, pourable compound that cures at normal temperatures to become an extremely tough and durable solid. Chockfast was specifically developed for chocking marine main propulsion and auxiliary machinery and since its introduction in 1963 has earned the approval of the major classification societies worldwide.
Other shipboard applications include…Sterntube & Strut bearings, Pintle & Rudder Bearings, Pedestal Bearings, Steering Gears, Stern Winches, Engine Room Pumps, Cargo Pumps, Cable Penetrations, Large Ball or Roller Bearings, Bow Thrusters and Anchor Windlasses.

Chockfast is a registered trademark of the epoxy resin made by ITW Philadelphia Resins Corp.

The resin itself can be used in an infinite number of applications but it was developed especially for the chocking of marine diesel engines. Due to the resins physical characteristics the costs gained by the quick, easy and trouble free application have made Chockfast the preferable way to mount diesel engines.

Some of the points raised by the use of Chockfast are:

Installation and chocking of the engine is done within several hours instead of days.
The hardened chock has perfect fit between engine and foundation and therefore spreads the engine forces evenly over the entire bedplate thus eliminating fretting of the contact surfaces.
