Opis:: The article compares combined systems in naval applications. The object of the analysis is the combined gas turbine/steam turbine system which is compared to the combined marine low-speed Diesel engine/steam turbine system. The comparison refers to the additional power and efficiency increase resulting from the use of the heat in the exhaust gas leaving the piston engine or the gas turbine. In the analysis a number of types of gas turbines with different exhaust gas temperatures and two large-power low-speed piston engines have been taken into account. The comparison bases on the assumption about comparable power ranges of the main engine.

Powiązania:: https://bibliotekanauki.pl/articles/260028.pdf
Data publikacji:: 2018
Wydawca:: Politechnika Gdańska. Wydział Inżynierii Mechanicznej i Okrętownictwa
Tematy:: self-ignition engine
combined systems
steam turbine
Opis:: This paper presents optimization of selected combined diesel engine-steam turbine systems. Two systems: the system combined with waste heat one-pressure boiler only and its version containing additionally low-pressure boiler proper feeding degasifier and the system of two-pressure cycle, were taken into considerations. Their surplus values of power output and efficiency associated with utilization of waste heat contained in piston engine exhaust gas were compared to each other. For the considerations two high-power low-speed engines were taken into account. The main engines of comparable power of about 54 MW produced by Wartsila and MAN Diesel & Turbo firms, were selected.

Tytuł:: Total ship operability –review, concept and criteria
Autorzy:: Ghaemi, M. H.
Olszewski, H.
Powiązania:: https://bibliotekanauki.pl/articles/259127.pdf
Data publikacji:: 2017
Wydawca:: Politechnika Gdańska. Wydział Inżynierii Mechanicznej i Okrętownictwa
Tematy:: ship operability
operability limitation criteria
safe operation level
Opis:: The ship operability can be understood and analysed in different manners, and its quality is described using different indexes by different authors. Practically, there is no general and widely accepted description of total ship operability in the literature, nor in the rules of classification societies, which would include both seakeeping and manoeuvrability characteristics of a ship, and simultaneously take into account all ship subsystems and, what is most important, comfort and safety of people on board. The aim of this paper is to propose a general definition of total ship operability and name, adjust, describe and justify criteria which should be considered in the ship operability analysis, as well as to provide a relevant algorithm paving the road for further investigation on total ship operability determination.

Tytuł:: FEM analysis and experimental tests of rigid riser hanging system
Autorzy:: Olszewski, A.
Wodtke, M.
Wójcikowski, A.
Powiązania:: https://bibliotekanauki.pl/articles/259405.pdf
Data publikacji:: 2018
Wydawca:: Politechnika Gdańska. Wydział Inżynierii Mechanicznej i Okrętownictwa
Tematy:: offshore engineering
riser hanging system
FEM simulation
experimental tests
Opis:: The article presents the analysis, project, and experimental examination of an original rigid riser for Coil Tubing Pipes. The principle of riser operation is based on the use of friction forces. The research included the FEM analysis of the designed riser, calculations of the required bolt tensions, and checking the effect of the clamping force on stress distribution in the pipeline. The results of computer simulation were verified on a specially designed test rig. The described riser design was implemented on the LOTOS Petrobaltic platform, thus eliminating the need for purchase and installation of expensive elastic risers.

Powiązania:: https://bibliotekanauki.pl/articles/259856.pdf
Data publikacji:: 2018
Wydawca:: Politechnika Gdańska. Wydział Inżynierii Mechanicznej i Okrętownictwa
Tematy:: offshore engineering
water injection flowlines analysis
FEM simulation
Opis:: The article describes the result of theoretical research aimed at assessing the loads and operating conditions of a Coiled Tubing pipeline injecting water, suspended to the mining platform of Lotos Petrobaltic. For this purpose, appropriate calculation models have been developed using the Finite Element Method (FEM), taking into account the nature of the analyzed object and its loads. The analyzes were carried out for two pipes (previously operated and newly proposed) differing in geometrical and strength parameters. The research was carried out for selected directions of load on the pipeline (originating from sea waves) and various variants of attaching the suspended pipeline to the mining platform.
