The L-Class from the Shell oil company was a series of VLCC crude oil tankers built in the 1970s .
history
The designation L-Class was derived from the ship name of the series, which began with the letter "L". Shell ordered the series from several shipyards in Northern Ireland, Denmark, Japan, France, Germany and the Netherlands in the early 1970s. The individual designs of the various shipyards were partly similar in terms of their rough dimensions, but were not standardized. The ships of the Bremer Vulkan and Harland & Wolff shipyards , whose plans had been coordinated, were an exception . Originally, all ships were supposed to have load capacities between around 255,000 and 280,000 tons, but the majority of the construction contracts, as was often the case in those years, were converted into those for even larger units. The French design by Chantiers de l'Átlantique was left at 282,000 tons. The Dutch Verolme Dok en Scheepsbouw Maatschappij built a ship with 255,000 tons and one with 318,000 tons deadweight. The original design from Harland & Wolff was ordered in 1971 with a load capacity of 256,000 tons, some units were built with a load capacity of 270–280,000 tons and some with a load capacity of 313,000 tons. The three Bremer Vulkan ships were commissioned in 1971 with a load capacity of 270,000 tons and the plans were increased to 313,000 tons in 1972. The orders to Odense Staalskibsværft were placed in 1970 with 282,000 tonnes load capacity and increased to 310,000 tonnes in 1972. The two ships built by Mitsui Shipbuilding & Engineering Company had already been ordered with a deadweight of 311,000 tons.
In the course of the tanker crisis, when the L-tankers were completed, Shell initially decided to scrap the smaller H-class and V-class ships that had become superfluous . In addition, many of the completed L-tankers have since been launched . The poor economy in tanker shipping in the late 1970s and 1980s due to the reopening of the Suez Canal and the large tonnage overcapacities ultimately led to ten L-class tankers being sold to other shipping companies from the early 1980s and a further nine in the mid-1980s Units were sold directly to scrapping yards . On the other hand, Shell bought four comparable used ships as early as 1990 and incorporated them with L names into the rest of the existing fleet. Several units were later used as floating oil storage facilities.
description
The ships are designed as pure crude oil tankers in single-hull construction. The deckhouse was arranged far aft above the engine room, the upwardly tapered chimney stood separately from it on the aft deck structure behind the bridge house. The tankers had two continuous longitudinal bulkheads and a different number of transverse bulkheads depending on the type of construction. All ships had slop tanks and two side tanks for ballast water. The manifold with two booms was placed amidships. There were differences within the series by which the individual designs could be distinguished. For example, there were fore ships with or without a bulbous bow, although the bulbous bow design of the various shipyards differed significantly.
Two steam turbines from STAL-Laval , General Electric or Kawasaki were used as drive systems, some of which were manufactured under license from the respective shipyards. The turbines gave their power to a single fixed propeller via a reduction gear.
