Outline of oceanographic engineering ship

Abstract

The invention discloses an outline of an oceanographic engineering ship. A head part of the engineering ship is provided with a forward bent turtle back type spherical head; the spherical head is provided with a peach-pit type cross section and a V-shaped forebody; the outline of the head part is smoothly transited from a head shoulder part to a ship middle part; the bottom of a middle section of the ship is made into a bevel type bilge and is respectively and gradually transited from a ship head section and a stern section to a circular bilge along a longitudinal direction; large-size triangular box-shaped bilge keels are arranged on two sides of the bevel type bilge at the bottom of the middle section; a bottom longitudinal flow barge outline is adopted in a middle tail part of the ship; and the bottom is linearly warped upwards. The outline of the oceanographic engineering ship meets the requirements of energy conservation and environmental protection of the oceanographic engineering ship while efficiently reducing the unavoidable responding amplitude for terrible weather and marine environment of the oceanographic engineering ship, thereby achieving an excellent fluid dynamical property, reducing resistance by 19%, promoting 0.5 times of shipping speed and being characterized by safety and reliability.

Description

technical field [0001] The invention relates to the technical field of ocean engineering ships, in particular to a line shape of an ocean engineering ship. Background technique [0002] The task of the offshore engineering ship is to provide anchor-handling operations, towing, and shifting operations for deep-sea offshore oil platforms and auxiliary ships, supply drilling mud, cement, drilling water, fuel oil, fresh water and other supplies for offshore oil platforms, and take charge of guarding, firefighting, Rescue and other tasks. [0003] The deep-sea offshore oil platform is in the ocean environment with high winds and waves all the year round. The external environmental conditions of its design are based on its living conditions, that is, the most severe external force with a certain probability of 50 years, 100 years or even 10,000 years is used for assessment. As a new type of offshore engineering ship serving deep-sea offshore oil platforms, although it does not ne...

AI Technical Summary

Problems solved by technology

As a new type of offshore engineering ship serving deep-sea offshore oil platforms, although it does not need to consider such a strict ring mirror, it is not like an ocean transport ship that can change its course or shelter from the wind before the arrival of a big storm. It is a service ship on standby and rescue. Stormy waves are inevitable
