High-seaworthiness separable pentamaran and working method thereof

PendingCN121493153ADavitsHoisting/lowering gearMarine engineeringMechanical engineering
The invention relates to a high-seaworthiness separable pentamaran and a working method thereof. A high-seaworthiness separable pentamaran comprises a mother ship, two sub-ship pairs are arranged on the mother ship, and a single sub-ship pair comprises two sub-ships which are symmetrically arranged relative to the mother ship; the deck of the mother ship extends towards the two sides respectively to form symmetrical connecting bridges, the bottoms of the two connecting bridges are each provided with at least one containing groove, the containing grooves and the son ships are arranged in a one-to-one correspondence mode, and a connecting module is installed in each containing groove in a matched mode. The single sub-ships are connected into the corresponding containing grooves through the connecting modules, or the single sub-ships are separated from the corresponding containing grooves through the connecting modules. By arranging the separable mother ship and the multiple pairs of son ships, the interisland transportation requirement can be met based on multiple modes, adaptability is high, seakeeping performance is good, sailing can be conducted under the high sea condition, and therefore the interisland transportation efficiency is effectively improved.

Green PCTC fire rescue layout structure

This invention provides a green PCTC (Potentially Controlled Traction Control) fire-fighting and life-saving layout structure, including lifeboats positioned on the port side of the stern of the highest deck of the ship. A meeting point is located forward of the lifeboats, and escape routes pointing to the meeting point are planned on the corresponding decks with arrows. The planning criteria for the escape routes include: lower decks prioritize routes to upper decks; intermediate compartments prioritize routes to side compartments; ship's side positions prioritize routes to the midships position; bow positions prioritize routes to the stern position; and locations with access passages prioritize using those passages, while locations without access passages prioritize routes close to the compartment walls. This invention enables rapid deployment of lifeboats, and in conjunction with the escape passages on the decks, improves the speed and efficiency of fire-fighting and life-saving operations.
