IV. Ask as many questions as possible to the following sentences:

  1. A sternpost is the upright structural member or post at the stern of a ship, to which is attached the transoms and the rearmost part of the keel.

  2. In modern warships, particularly cruisers and destroyers, the stern is usually where the helicopter pad is located.

  3. Aircraft carries typically use the deck space in the stern part of the ship for the recovery of incoming aircraft.

  4. Other features of the stern included lanterns and ensign.

  5. In modern cruise ships, the stern is frequently the location of the dining – room.

V. Make up sentences using the following words and word combinations:

The stern area, rear part of a ship, extend upwards from … to, the steering apparatus, by extension, officers’ quarters, stern rake, the advent of screw – powered vessels, the location of the equipment.

VI. Insert the missing words using the text:

  1. The … is the rear or aft part of a …

  2. The stern technically … as the area built up over the …, extending upwards from the … to the …

  3. The stern was the … of the officers’ …

  4. Other features of the … included lanterns and the …

  5. In modern … …, the stern is frequently the location of the … room.

VII. Translate the text: “Steering engine.”

A steering engine is a power steering device for ships.The first steering engine with feedback was installed on Isambard Kingdom Brunel's Great Eastern in 1866. This was a steam-powered mechanical amplifier used to drive the rudder position to match the wheel position. The size of the Great Eastern, by far the largest ship of its day, made power steering a necessity.

Large steam-powered warships with manual steering needed huge crews to turn the rudder rapidly. The Royal Navy once used 78 men hauling on block and tackle gear to manually turn the rudder on the HMS Minotaur (1863), in a test of manual vs. steam powered steering.

VIII. Translate the following sentences from Russian into English:

  1. Корма – задняя часть судна или лодки.

  5. На корме современных лайнеров чаще всего находится столовая.

IX. Retell the text: “Stern”

Unit 27. Ship hull structure elements

I. Read and translate the following text:

Structural Elements of a Ship's Hull

This diagram shows the key structural elements of a ship's main hull (excluding the bow, stern, and deckhouse).

  1. Deck structure

  2. Transverse bulkhead

  3. Inner bottom shell plating

  4. Hull bottom shell plating

  5. Transverse frame

  6. Keel frame

  7. Keelson

  8. Longitudinal stiffener Hull side beam

    1. Total Loads, Bending, and Strength

The total load on a particular section of a ship's hull is the sum total of all primary, secondary, and tertiary loads imposed on it from all factors. The typical test case for quick calculations is the middle of a hull bottom plate section between stiffeners, close to or at the midsection of the ship, somewhere midways between the keel and the side of the ship.

    1. Standard Rules

Ship classification societies such as Det Norske Veritas, American Bureau of Shipping, and Lloyd's Register have established standard calculation forms for hull loads, strength requirements, the thickness of hull plating and reinforcing stiffeners, girders, and other structures. These methods often give a quick and dirty way to estimate strength requirements for any given ship. Almost always those methods will give conservative, or stronger than precisely required, strength values. However, they provide a detailed starting point for analyzing a given ship's structure and whether it meets industry common standards or not.
