Master thessis The concept of free ballast oil tanker 71000 tDW Lwl = 251,8 m, B = 31,22 m, TB = 3,75 m, T = 13,00 Thesis presents the concept of a ship without ballast that is both economically and environmentally friendly.

AIRCRAFT CARRIER IN DAMAGED CONDITION The basic purpose of this paper was to check out the capability of aircraft carrier after the damage regarding the sufficient stability to be still operational and combat capable i.e. to withstand the wind and waves in damaged condition.
INTRODUCTION: Added resistance of ship in waves was calculated for open hatch vessel (H-type vessel) within industrial project in January 2013. Open hatch vessel is designed to transport unitized cargoes, project cargoes and containers. The vessel is typically fitted with two gantry cranes for self loading and unloading. Hatch covers for holds are opened and closed by mean of gantry crane. Space on those hatch covers can also be used to carry containers, lumber or project cargoes. The project was conducted by the Chair for Ship Design and Offshore Engineering and Brodarski Institut d.o.o. in Zagreb. As overall result of seakeeping analysis and added resistance estimation was probability of green water occurrence.
Dynamics of FPSO with Polyester Mooring Lines is part deep see mooring research that takes palace on the Chair. Polyester mooring lines are commonly used at deep-water locations for a floating production, storage and offloading unit (FPSO). The stiffness model of highly extensible polyester mooring lines is studied as part of dynamic analysis of a FPSO. Coupled dynamics of FPSO and deepwater mooring system with taut polyester mooring lines is observed. Calculations are done in time domain utilizing nonlinear finite element method (FEM). Newly derived additional stiffness matrices are used to approximate the influence of elongation of mooring line to its geometric stiffness.
SHIP MOTION IN WAVES
ADDED RESISTANCE OF SHIP IN WAVES An extended seakeeping analysis of H-type vessel was performed to determine the relative motions for sea conditions across a range of wave periods to be expected during exploitation.
DYNAMICS OF FPSO WITH POLYESTER MOORING LINES High elongation of polyester rope (15% at break point) has great influence on mooring system.
The relative motion at various points along the ship was considered alongside the local freeboard to estimate the green water probability. Hhydrodynamic calculation are based on 2D boundary element method.
Most important part of the analysis was determination the added resistance of ship and estimation of the maximum sustainable ship speed in head waves. One parameter Pierson-Moskowitz spectrum was used for modeling of fully developed sea.

Comparison between the improved model developed in this research and current equivalent model (Tahar & Kim (2008)) is done in static case study. The single mooring line that can be analytically described was base for comparison. The improved model achieved better matching with analytical results.
Satisfactory stability and results of the improved model are found in the coupled dynamic analysis of moored FPSO.

MORSKA TEHNIKA Na Katedri je razvijena intenzivna suradnja s industrijom, naročito u području morske tehnike. Rezultati znanstvenog istraživanja primjenjivani su na rješavanju složenih problema u rekonstrukciji pučinskih objekata za suvremene uvjete tržišta te u razvoju projektiranja i tehnologije izgradnje podmorske infrastrukture: podizanje teških tereta na valovitom moru i polaganje podmorskih cjevovoda.
OFFSHORE TECHNOLOGY Very active cooperation with the industry was developed on the Chair, specially in the offshore area. The results of research and developing were applied in the solving complex problem present in upgrading offshore platforms as well as in designing and constructing subsea infrastructure: heavy lifting in waves, subsea pipe laying.
COOPERATION WITH OFFSHORE INDUSTRY
SEDU PLATFORM UPGRADING Levingston 111 C SEDU type platform has been upgraded and modified for the contemporary market requirements on the basis of originally developed structural design - leg extension, cantilever enlargement, variable load increase. (red colored parts)
HEAVY LIFTING AT SEA Lifting of heavy weights at open sea is daily present in the construction of subsea offshore infrastructure. The limit sea state which is safe for such complex activity is the most important design data necessary for planning the operation.
SUBSEA PIPELAYING Two essential problems characterize design and installation of the subsea pipeline in the coastal area: strong hydrodynamic loading due to waves and sea current as well as the bending loading of the pipe on the curved and uneven sea bottom. The equilibrium shape of the bended pipeline when it is exposed to gravitational, operating and hydrodynamic loading is analyzed by the nonlinear finite element model which includes the large displacement and the contact problems between the pipe and sea bottom.
LABIN
The design was developed and approved according to rigorous ABS offshore rules.
The critical situations of upgraded platform in operating and surviving conditions were investigated on the complex FEM model (500.000 DOF) which includes structural characteristics as well as hydrody-namic and aerodynamic loading

The coupled multi-body dynamics (crane barge – suspended mass) must be analyzed to define the resonant range with respect to sea wave spectrum. Sometimes the nonlinear characteristics of the mooring system must be also taken into consideration.
