Heave Motion

One of the major requirements for a floating vessel designed to support top tensioned risers is to have the heave response within a minimum specified range in extreme environments. The heave has a significant influence on the riser stroke. Usually floater designs aim to use conventional riser tensioners, available commercially, which typically have a maximum stroke range in the order of 30 to 35ft. One of the limitations of traditional Semi-submersible designs to support dry trees is that the heave ranges seen in central Gulf of Mexico (GoM) are outside the range that can apply a conventional tensioner. The Extendable Semi-submersible (E-Semi) utilizes a retractable Second Tier Pontoon (STP) to suppress heave motions and reduce its heave motion in order to support top tensioned risers in central GoM ultra deep waters. The design is based on an established deep draft Semi-submersible with the STP attached. This paper presents a comparison between motion characteristics of the deep draft Semi-submersible with and without the STP attached. The comparison is based on numerical computations to predict the responses together with model test results in the same environments. The analysis essentially shows the effectiveness of the STP is suppressing the heave motion.

AbstractPodocotyle bathyhelminthos n. sp. (Opecoelidae: Plagioporinae) is described from the cusk-eel, Luciobrotula corethromycter Cohen, 1964 (Ophidiiformes: Ophidiidae), collected at depths of 622-1,280 m in the northern Gulf of Mexico and Caribbean Sea off Colombia. The new species is distinguished by possessing a combination of the following features: an elongate oval body shape, a sucker width ratio of 1:1.4-1.9, deeply lobed and irregularly-shaped testes, a cirrus-sac that extends just in to the hindbody, a trilobed ovary and vitellarium that extend to the ventral sucker level. Several unique features in P. bathyhelminthos n. sp. were not present in all, or almost all, recognized species of Podocotyle including a conspicuous deep cleft at the posterior end of the worm, a small transverse ridge on the ventral surface immediately anterior to the ventral sucker, uterine loops extending ventral to the caeca and, at times, lateral to the caeca, a thick-walled metraterm extending 1/3 to 1/2 the length of the cirrus-sac and P. bathyhelminthos n. sp. parasitizes a deep water piscine host. Podocotyle etheostomae Aliff, 1973 is declared a nomen nudum. A brief discussion of Podocotyle Dujardin, 1845 in deep waters is presented, and a gastropod, caridean shrimp and cusk-eel are hypothesized as hosts in the life cycle of P. bathyhelminthos n. sp. in the deep sea.

Abstract. In the Gulf of Mexico (GoM) at least three near-surface water masses are affected by mesoscale processes that modulate the biogeochemical cycles. Prior studies have presented different classifications of water masses where the greater emphasis was on deep waters and not on the surface waters (σθ
