TREATMENT OF PETROLEUM REFINERY WASTEWATER IN AN INNOVATIVE SEQUENCING BATCH REACTOR
… one of the main drawbacks of sequencing batch reactors. The aim of this study therefore is to improve sludge settleability by introducing a novel, two-stage settling sequencing batch reactor (TSSBR) separated by an anoxic stage. The performance of the TSSBR was compared with that of a …

Asset integrity case development for normally unattended offshore installations
This thesis proposes the initial stages of the development of a NUI – Asset Integrity Case (Normally Unattended Installation). An NUI – Asset Integrity Case will enable the user to determine the impact of deficiencies in asset integrity and demonstrate that integrity is being managed. A key driver …

Formal fire safety assessment of passenger ships
… accommodation zone and electrical systems, etc, the single most important fire hazard onboard a ship may be the man himself, either unintentionally or intentionally. 'Fire safety on passenger vessel' has continued to be the focus of attention on passenger ships. The work described in this …

MEASUREMENT, MODELLING AND ANALYSIS OF CONTAINER PORT PERFORMANCE
This thesis aims to develop a new framework of container port/terminal performance measurement, modelling and analysis. There is a need for a new performance measurement framework not only to meet the need of port stakeholders, but also to develop diagnostic tools capable of supporting …

AN EMPIRICAL STUDY OF FLOOD WAVE IMPACT PRESSURES TO DETERMINE THE EFFECTIVENESS OF NEW SEAWALL DESIGNS USING A DAM-BREAK APPROACH
Coastal flooding and erosion, a major consequence of coastal natural events can result in physical devastation, threats to human health and safety, detrimental effects on ecosystems, and severe economic losses to individuals and to society. These potentially devastating consequences are therefore …

Analytical Quality Control in Shipping Operation Using Six Sigma Principles
A large number of benefits achieved through the successful implementation of Six Sigma programmes in different industries have been documented. However, very little research has been conducted on their applications in the shipping sector, especially in the Onshore Service Functions (OSFs) of …

APPLICATION OF FORMAL SAFETY ASSESSMENT FOR DRY DOCKING EVOLUTION
This research has evaluated the rules, guidelines and regulations related to docking a ship in floating-graving yards. Historical failure data analysis is carried out to identify associated components, equipment and the area of defects related to ship docking evolution problems. The current status …

Evolutionary Algorithms and Simulation for Intelligent Autonomous Vehicles in Container Terminals
The study of applying soft computing techniques, such as evolutionary computation and simulation, to the deployment of intelligent autonomous vehicles (IAVs) in container terminals is the focus of this thesis. IAVs are a new type of intelligent vehicles designed for transportation of containers in …

Probabilistic deterioration modelling and time-dependent reliability analysis of coastal defences
… effects and sea level rise will increase the hydraulic loads and frequency of the future extreme events, which lead to a more challenging performance deterioration prediction. The main failure mechanisms in coastal flood defences, e.g. wave overtopping and piping will be affected due to the …

The design of a deep water catenary riser
… is supported by a sub-surface buoy which is hydraulically connected to an FPSO using flexible flowlines. This hybrid connection has the advantage of decoupling FPSO and riser motions. Design development is carried out by examining a range of critical areas.

A three-dimensional technique for predicting first-and second-order hydrodynamic forces on a marine vehicle advancing in waves
… on the linearised body boundary condition for pitch and yaw motions are used for a realistic ship. When the calculated results are compared with available experimental data, the three-dimensional translating pulsating source, modelling gives better correlations than the three-dimensional …

Experimental and numerical studies on oil spilling from damaged oil tankers
It is well understood that the spilled oil from damaged oil tankers poses a severe threat to the marine environment. Although great efforts have been devoted to studying the oil spilling from damaged oil tankers, especially double hull tanks (DHTs), the majority is subjected to an ideal condition …

Numerical investigation of breaking waves and their interactions with structures using MLPG_R method
Meshless Local Petrov-Galerkin method based on Rankine source solution (MLPG_R) has been developed by Dr. Qingwei Ma (Ma, 2005b) and has been used to simulate the nonlinear water wave problems in 2D cases without the occurrence of the breaking waves. In this thesis, MLPG_R method has been further …

An experimental and theoretical investigation into the break-up of curved liquid jets in the prilling process
A pilot scale study of the dynamics of the break-up of curved liquid jets is presented. This work is motivated by an industrial process called prilling which is used in the manufacture of pellets. In this process a sieve-like cylindrical can spins rapidly on its central vertical axis. Molten liquid …
