Aluminum Helidecks

Tristan Mackintosh, Bayards

Abstract

The goal of this presentation is to introduce and educate the possibilities and advantages of aluminum structures especially helidecks for the offshore industry.

An important market for Bayards is the Offshore industry, as aluminum is the ideal material to use in the marine environment and can be the perfect solution when a rig structure or vessel has weight limitations.

About 25 years ago Bayards have supplied their first aluminum helideck for the North Sea Offshore industry, during the following years helidecks were frequently built at Bayards. In recent years the offshore industry started to discover the advantages of an aluminum helidecks.

Biography - Tristan Mackintosh

In the summer of 2007, straight out of school Mackintosh started working as a supervisor at Bayards, supervising helideck assemblies at the big Korean shipyards. January 2008 he started as a project manager at Bayards main office in the Netherlands, managing helideck projects for clients predominantly in South Korea.

After 1 year of working as a project manager Macintosh gained enough technical knowledge about aluminum structures to start in a commercial position. Beginning of 2009 he started as a business development manager, responsible for South East Asia, India and the Middle East. After successfully getting projects with Key clients in these areas in that year he was ready to move on to a new area.

In April 2010 Bayards opened a sales office in Houston in order to supply the GOM Offshore industry with light weight, non-corrosive aluminum structures.  Since then Macintosh is the area manger in Houston.

Wastewater Treatment Systems

Bruce Russell, JS&A Environmental Services, Inc. & SNAME Environmental Engineering Committee

Abstract

Illegal oil discharges, difficult to operate oily water separators, and associated costs and liabilities are among the leading concerns for ship operators, ship crews and maritime enforcement agencies.  “It Doesn’t Work.”  How many times have you heard the f-word* regarding your oily water separator (OWS)? (* frustration).  Following a comprehensive study and report, by SNAME’s T&R panel on OWS and Bilge Water (SNAME T&R Bulletin 6-1), of the root cause of OWS system failures and crew frustration the International Maritime Organization issued IMO MEPC Circular 677 Guide to Diagnosing Contaminants in Oily Bilge Water to Maintain, Operate and Troubleshoot Bilge Water Treatment Systems.

Dry-Tree Semisubmersible for Gulf of Mexico Application

John Chianis, P.E., President, Houston Offshore Engineering

Abstract

The Paired-Column Semisubmersible is a new and innovative concept that has been developed as an alternative to Spar for deepwater dry tree developments.

A design for metocean conditions associated with the onerous Central Gulf of Mexico region is presented.  Size and performance results of the Paired-Column Semi are compared to a similar Spar application.  Comparisons of motions, riser stroke, steel weight, installation procedures, etc. are addressed.

Paired-Column Semi predictions are also compared to results from a recent comprehensive model test program.

Because of its superior motion characteristics, application to a wet tree development where SCR fatigue is a major issue is also presented.

Biography - John Chianis

John has over 32 years of experience in the field of offshore and marine engineering. His project experience includes design of TLPs, FPSOs, single point moorings, Spars and semisubmersibles. Specific areas of competence are structural design, finite element analysis, Naval Architecture, hydrodynamic motions and mooring analyses, regulatory submissions, fatigue analysis, software development and model testing.

John has participated in and directed many offshore projects ranging from concept selection and development through detailed engineering, fabrication and installation. He participated in the development of Industry standards and recommended practices for API and ISO.

 

High Performance Semisubmersible Solutions for Dry Tree Applications in Harsh Environment

Alaa Mansour, PhD., Marine Engineering Manager, INTECSEA, WorleyParsons Group

Abstract

The Damper Chamber Colum (DCC) Semi and the Free-Hanging Solid Ballast (FHSB) Semi are two new and innovative designs that offer suitable motion response for dry tree applications in ultra-deepwater harsh environmental conditions and therefore they can be used as alternatives to Spar platforms.

In this presentation, description of the two new designs will be provided. The proposed project execution plan including fabrication, transportation and installation phases will be illustrated. FHSB Semi and the DCC Semi designs to support dry tree applications in 8,000 ft (2,438 m) of water and in the harsh Central Gulf of Mexico region will be presented. The efficiency of the two designs defined by the payload to hull and deck steel will be addressed. Numerical results of the motion response and riser stroke will be included in this presentation.

The advantage of using the new designs in wet-tree applications will also be illustrated.

Extreme Load-Response Mechanisms of a Tension Leg Platform due to larger wave crests - some results of the CresT JIP

Arjan Voogt, MARIN

Abstract

For the design of ships and offshore structures the the wave loading and response is more complex. Obtaining largest crest height which can be expected in their lifetime is of further insight in extreme waves and their impact required a key importance. This was confirmed by several incidences e.g. strong cooperation between metocean specialists, wave in hurricanes in the Gulf of Mexico during the recent years. modeling experts, hydrodynamicists and reliability specialists. This is why MARIN started up the CresT JIP with a number of This is why the CresT (Cooperative Research on Extreme Seas partners. The CresT JIP is now completed and some results of and their impacT) Joint Industry Project has been carried out. The extreme wave load and response mechanisms observed during model tests with a TLP will be presented.

The Triality an Innovation Concept Design

Tony Teo, DNV

ABSTRACT

The introduction of a new crude oil tanker concept that is fuelled by liquefied natural gas, has a hull shape that removes the need for ballastwater and will almost eliminate local air pollution. This concept vessel also recovers hundreds of tons of cargo vapors on each voyage and represents a major step towards the new environmental era for the tanker shipping industry. The new crude oil concept vessel, named Triality, has been developed through a DNV innovation project. As its name indicates, it fulfills three main goals: it is environmentally superior to a conventional crude oil tanker, its new solutions are feasible and based on well-known technology, and it is financially attractive compared to conventional crude oil tankers operating on heavy fuel oil.

Less harm to the environment.

The Triality concept VLCC has been compared to a conventional VLCC. Both ships have the same operational range and can operate in the ordinary spot market.
Compared to the traditional VLCC, the Triality VLCC will:
- emit 34% less CO2
- eliminate entirely the need for ballast water
- eliminate entirely the venting of cargo vapors (VOCs)
- use 25% less energy

Less harm will also be caused to the health of people living close to busy shipping routes and ports as NOx emissions will be reduced by more than 80% while emissions of SOx and particulate matter will fall by as much as 95%.
The new concept tanker has two high pressure dual fuel slow speed main engines fuelled by LNG, with marine gas oil as pilot fuel. Two IMO type C pressure tanks capable of holding 13 500 m3 LNG - enough for 25 000 nautical miles of operation - are located on the deck in front of the superstructure.

The generators are dual fuel (LNG and marine gas oil) while the auxiliary boilers producing steam for the cargo oil pumps operate on recovered cargo vapors (VOCs).
