the Yombo field off the Republic of Congo. The conversion included installing additional accommodation capacity as well as production-related equipment. The converted vessel was renamed La Noumbi on 26 July 2018. Design (as oil tanker) General characteristics Tempera is long overall and between perpendiculars. The moulded breadth and depth of her hull are and , respectively, and from keel to mast she measured . Her gross tonnage is 64,259 and net tonnage 30,846, and the deadweight tonnage corresponding to the draft at summer freeboard, , is 106,034 tons, slightly less than in Mastera. In ballast Tempera draws only of water. The foreship of Tempera is designed for open water performance with a bulbous bow to maximize the hydrodynamic efficiency. The ship is, just like any other ice-strengthened vessel, also capable of running ahead in light ice conditions. The stern is, however, shaped like an icebreaker's bow, and Tempera is designed to operate independently in the most severe ice conditions of the Baltic Sea. For this purpose the ship is also equipped with two bridges for navigating in both directions. The ship is served by a crew of 15 to 20 depending on operating conditions during winter and maintenance work during summer. Tempera is classified by Lloyd's Register of Shipping. Cargo tanks and handling Tempera has six pairs of heated, partially epoxy-coated cargo tanks and one pair of fully coated slop tanks, all divided by a longitudinal center bulkhead and protected by double hull, with a combined capacity of at 98% filling. For cargo handling she has three electrically driven cargo oil pumps with a capacity of 3,500 m3/h × 130 m and one cargo oil stripping pump rated for 300 m3/h × 130 m. The cargo can be loaded in 10 hours and discharged in 12 hours. Each cargo tank has two and both slop tanks one automated tank cleaning machines as well as holes for portable tank cleaning machines. The ship's ballast water capacity of is divided into sixteen segregated ballast tanks, six pairs in the double hull around the cargo tanks, two fore peak tanks and two aft peak tanks. She has two electrically driven ballast pumps rated at 2,500 m3/h × 35 m and 3,000 m3/h × 70 m. The ballast capacity is needed to maintain correct trim especially during drydocking — the empty ship has an aft trim of and an uneven weight distribution may damage
