Shell and tube heat exchangers require tubes to be plugged upon the detection of a leak. This prevents the two liquids from mixing inside the heat exchangers. In order to perform regular maintenance on a plate type heat exchanger, the plate stack is separated and the plates a cleaned to improve heat transfer.
Shell Rotella is a line of heavy-duty engine lubrication products produced by Shell plc. The line includes engine oils, gear oils and coolants. The oil carries both the American Petroleum Institute (API) diesel "C" rating as well as the API gasoline engine "S" rating. Ratings differ based on the oil. Rotella oils, like the T3 15W-40, meet both ...

A shell-and-tube heat exchanger is a class of heat exchanger designs. [1] [2] It is the most common type of heat exchanger in oil refineries and other large chemical processes, and is suited for higher-pressure applications. As its name implies, this type of heat exchanger consists of a shell (a large pressure vessel) with a bundle of tubes ...
A marine LNG engine is a dual fuel engine that uses natural gas and bunker fuel to convert chemical energy in to mechanical energy. Due to natural gas' cleaner burning properties, the use of natural gas in merchant ship propulsion plants is becoming an option for companies in order to comply with IMO and MARPOL environmental regulations.
A "Scotch" marine boiler (or simply Scotch boiler) is a design of steam boiler best known for its use on ships. Sectional diagram of a "wet back" boiler. The general layout is that of a squat horizontal cylinder. One or more large cylindrical furnaces are in the lower part of the boiler shell. Above this are many small-diameter fire-tubes ...
The Rolls-Royce MT30 (Marine Turbine) is a marine gas turbine engine based on the Rolls-Royce Trent 800 aero engine. The MT30 retains 80% commonality with the Trent 800, the engine for the Boeing 777. The maximum power rating is 40 MW and minimum efficient power 25 MW. [1] Rolls-Royce announced the MT30 program on 11 September 2001.
