Hermes (aft) and Heracles (fwd) and Zeus (fwd) are the smallest, cheapest, easiest emergency towing arrangements type approved by all major Registers and fully complying to I.M.O. resolution MSC35(63) of 94.05.20 and O.C.I.M.F. recommendations.

The main components of the two models, 1.000 kN and 2.000 kN are :
  • Pick-up gear
  • Panama chock
  • Strong point
  • Deploying drum
  • Bow arrangement
Pick-up gear

This box is installed at stern and contains the light buoy, the messenger rope already connected to the towing steel wire rope.
One man only unlocks the cover just before abandoning the ship and from this point further all operations can be managed by the tug, because the lights buoy fells down awaiting for the tug.

  Panama chock

The Panama chock is tested according both to I.M.O. and O.C.I.M.F. requirements. It is type approved, wich means that the prototype has been tested at our testing bench at 1962 / 3924 kN at 30 / 60 / 90 degrees pull.
Most of the Panama chocks existing at bow and stern of the tankers are fully workable for general mooring purposes but they do not comply to I.M.O. requirements, so they must be replaced with approved ones.

Strong point

This strong point can be opened into two parts to enable the hawsing of the steel wire rope. The prototype has been tested at our testing bench at 1962 / 3924 kN at the presence of American bureau of shipping, Bureau veritas, Class NK, Det norske veritas, Lloyd's register of shipping, Rina. It must be inserted in the deck, after dwg approval by the classification company.
