    welding on in-service diesel oil tank

    I am aware of both approaches to the task; I've heard of Keeping the tank filled to maximum/fill trip level and then weld only below this level. I know of Draining degassify and clean the tank then do the welding. I have welded on active bunker c tanks and pipelines before but I am more...

    Installing fire protection on In-service diesel Oil tank

    Hi all Is there a code, procedure for welding on an in-service AST diesel oil tank. We are installing fire protection around these tanks in the form of fixed water spray cooling rings & foam top surface discharge. The need for welding is for the brackets that will support the cooling rings. I...

    HFO no 6 (bunker C) viscosity vs temperature

    We are designing a submarine pipeline to transfer heavy fuel oil from a off-shore mooring. Does anyone here has a reference chart on the viscosity of HFO no. 6 (bunker c)at various temperatures. We are aware of the temperature at offload and the related viscosity, however after pumping, and some...

    BUILDING VIBRATION

    Start by carrying out a condition assessment. Keep it limited to just theoretical analysis, visual defects, do some NDT, no demolition such as cores. Look at what changed in the bldg history and what changed in terms of loading, occupany change of use of spaces. Vibration can be induced by some...

    Gas Turbine Base Failure

    The unit turbine as well as generator has continuous vibration indicators installed. Despite the turbine never exceeding allowable, if there was vibration on the turbine due to a gearbox between the turbine and the generator shafts these vibrations would not be transfered either way, thus...

    Gas Turbine Base Failure

    Analysing the failure which theoretically could derive from: Insufficient development of anchor bolts, as well as insufficient steel detailing to transmitt load or capacity of steel reinforcement design, these are all design shortcomings. The question now is; how liable is the principal...

    Gas Turbine Base Failure

    I just finished reviewing the article "from experience Alternatives to ACI 318-02 July 2004" and it actually speaks to the exact same thing. The problem is how to go about doing this with considerable demolition & downtime. Considering Steel Dowells with a nut at the end in a high strenght &...

    Gas Turbine Base Failure

    We were contemplating grouting with conbextra EP10 as a temporary fix. Whats your opinion of the failure. The maximum vibrations were 12 mm/sec with an allowable of 25. The crack seem to go 3 inches beyound the rebar cage on the pier. We only have 18 days to repair, your method would seem to...

    Gas Turbine Base Failure

    In the pictures attached, I have concluded that this failure is a tensile uplift due to the dynamic loading. The foundation system is a pile supported pier. It cracks along the top edge perimeter including vertically at the vertical edges/corners. Your comments on the failure as well as a...
