Hydrogel Technology in Shipping

Hydrogels are 3D polymer materials that can absorb and retain large amounts of water while maintaining structure.

In shipping, they are used mainly in environmental protection, corrosion control, fire safety, and smart materials.

What is Hydrogel?

  • Polymer network + high water content (up to 90–95%)

  • Flexible, lightweight, non-toxic (depending on type)

  • Can be engineered for specific functions

 Applications in Shipping

1️⃣ Oil Spill Response

  • Superabsorbent hydrogels can:

    • Absorb oil selectively

    • Help in containment and cleanup

  • Used in marine pollution control

2️⃣ Anti-Corrosion Coatings

  • Hydrogel-based coatings:

    • Act as moisture barriers

    • Deliver corrosion inhibitors slowly

  • Useful in:

    • Ballast tanks

    • Deck structures

    • Offshore platforms

3️⃣ Fire Protection Systems

  • Hydrogel fire blankets and coatings:

    • Absorb heat

    • Provide thermal insulation

  • Used in:

    • Engine rooms

    • Offshore rigs

4️⃣ Smart Sensors & Monitoring

  • Hydrogel sensors:

    • Detect humidity, salinity, or temperature

    • Used in cargo holds & cold storage

5️⃣ Cargo Protection

  • Moisture-control hydrogels:

    • Prevent cargo damage (grain, electronics)

    • Control condensation in containers

Future Scope

  • Eco-friendly antifouling coatings

  • Self-healing marine coatings

  • Carbon capture research materials

Advantages

  • Lightweight

  • High absorbency

  • Environmentally adaptable

  • Customizable properties

Main engine interlocks

Interlocks are provided so that the engine can be started or reversed only when certain conditions have been fulfilled. When there is a remote control of engines, it is essential to have interlocks. This reduces the possibility of engine damage and any hazards to the operating personnel. Turning gear Interlock . This device prevents the engine from being started if the Turning gear is engaged. Running Direction Interlock . This prevents the fuel from being supplied if the running direction of the engine does not match the Telegraph. Starting Air Distributor in end position . This prevents starting from taking place if the shifting of the Distributor has not been completed. Main Lube. oil pressure, Piston cooling pressure, Jacket water pressure, and important parameters must be above the required minimum. Auxiliary Blower Interlock . The Auxiliary Blower is provided in case of Constant pressure turbo charging. Air Spring pressure Interlock . In case of the present generation...

Why is a man hole door elliptical in shape?

Any opening in a pressure vessel is kept to a minimum and for a man entry an elliptical hole  is lesser in size than the corresponding circular hole. More over it is prime concern to have a  smoothed generous radius at the corners to eliminate stress concentration. Hence other  geometrical shapes like rectangle and square are ruled out.  To compensate for the loss of material in the shell due to opening, a doubler ring has to be  provided around the opening. The thickness of the ring depends on the axis length along the  dirrection in which the stresses are maximum and the thickness of the shell. It is important to  align the minor axis along the length of the vessel, as the stress in this direction is  maximum. Longitudinal stress: Pd/2t where P= pressure inside the vessel, d= diameter of the arc, t=  thickness of the shell plating  Circumferential stress: Pd/4t  More over a considerable material and weight saving is achieved as...
