Houston, Texas May 7, 2013 – Welaptega Marine, world leader in Moorings Fitness for Purpose Assessments (MFPA), is at OTC Houston this week to deliver a paper on life extension of mooring systems on offshore floating production facilities.
The paper, entitled “Mooring System Life Extension using Subsea Inspection Technologies,” will be presented by Welaptega Business Development Lead Engineer Tyler de Gier who co-authored the paper with business development engineer Scott Allan and CEO Tony Hall.
The paper covers aging infrastructure, mooring failures, and risk based inspection techniques.
Life extension requires progressive inspection strategy
Determining the potential for life extension of an asset requires a comprehensive understanding of the current state of a mooring system. This is achieved by executing a well-planned inspection strategy followed by engineering analysis of quantifiable results.
The paper will discuss Welaptega’s Progressive Inspection techniques using 3D and 2D imaging technologies and dimensional technologies for measuring chain and rope mooring systems. Progressive Inspection identifies potential risks on moorings and underwater assets and then takes action to quantify anomalies to gauge their seriousness.
Advances in mooring systems
The Welaptega paper will be presented as part of an OTC technical session on Advances in Mooring Systems. The session will take Place on Thursday May 9, 9:30-noon in Room 600 of the Reliant Park Conference Centre. The session will be be chaired by Tomasz Matlak of Schlumberger and Subir Bhattacharjee of ExxonMobil Production.
Welaptega is part of the Nova Scotia OTC delegation lead by the Maritime Energy Association and the Nova Scotia Department of Energy.
Founded in 1969, the Offshore Technology Conference (OTC) is the world’s foremost event for the development of offshore resources in the fields of drilling, exploration, production, and environmental protection.
Halifax, Nova Scotia _ Welaptega Marine has been awarded a contract to inspect the mooring system of the Nganhurra floating production storage and offloading (FPSO) facility operating in waters off the coast of North West Australia.
Welaptega has sent a team of specialist engineers to the facility to conduct a Progressive Inspection program using its Rope Measurement System (RMS) and 3D-modeling system (3DM).
“Our Progressive inspection philosophy is a guided examination of mooring systems that focuses on known problems and failure modes,” says Tony Hall, President and CEO of Welaptega Marine.
“When anomalies, wear or damage is identified, progressive inspection technologies are used to zero in on the problem and identify its characteristics and operational implications.”
Nganhurra FPSO is operated by Woodside Energy Ltd., and is the first oil production facility in the deep waters off the North West Cape.
The vessel operates in water depths of approximately 2000 feet and can process 100,000 barrels of oil per day. It has a storage capacity of one million barrels.

Welaptega will inspect a riser chain attached to a buoyancy tank on an FPSO
Halifax, Nova Scotia - Welaptega Marine, world leader in mooring integrity verification, has been awarded a contract to inspect riser moorings on the high-profile Petrobras Cascade Chinook development in the Gulf of Mexico.
Welaptega will measure mooring chains that connect four vertical risers to buoyancy tanks on the the BW Pioneer FPSO. The Pioneer is the world’s deepest FPSO, operating in 2600 meters of water 180 miles off the coast of Louisiana.
“This is part of a longterm life cycle mooring integrity inspection,” said Tony Hall, CEO of Welaptega Marine. “Petrobras and the US Bureau of Safety and Environmental Enforcement (BSEE) recognize the importance of regular inspection as part of a wider integrity strategy.”
A team of Welaptega engineers will deploy the Chain Measurement System (CMS), a Welaptega patented technology, to measure the length of each chain link and inter-grip zones on four riser mooring systems.
It is part of an on-going program of mooring inspection carried out by Welaptega on a six-monthly interval.
The Pioneer is the first FPSO production development approved in the Gulf of Mexico.
The job deploys in November. This is the fifth inspection conducted by Welaptega on this project. The contact was awarded to Welaptega by Veolia Water special services division.
London, Oct 30, 2012 _ Failures of mooring systems in offshore floating production are not easy to predict, but they do occur, and they will happen more often as infrastructure nears the end of design life.
“It is mission critical that we do the detective work up front on these ageing systems,” according to Tony Hall, CEO of Welaptega Marine. “It’s imperative that we identify any phenomenon that could put a facility at risk of failure.”
Hall, whose company specializes in risk-based mooring integrity verification, was speaking to a group of offshore integrity experts attending a seminar on ageing infrastructure. It was convened by the Oil, Petrochemical and Energy Risk Association (OPERA).
“It’s not good enough to do the postmortem on a failure. That’s too late. We need to be on the lookout for deteriorative mechanisms that put the system at risk of failure so preventive action can be taken.”
He said risk-based inspection must be guided by experience of mooring systems and industry best practice. This means looking for risky areas where a deteriorative phenomenon is known to have occurred before.
“Industry has already identified many of these phenomena through operational experience which has been captured in the Oil & Gas UK guidelines on mooring integrity management , and the various Joint Industry Projects on mooring integrity (JIP).”
He said it’s also important to identify other types of deterioration which may not have been associated with failure in the past but that could still lead to failure.
He pointed to mechanisms such as sulfate reducing bacteria, heavy wear and corrosion at the turret, and bird-caging of wire rope.
He said this issue is more important than ever now that offshore reservoirs are being extended for further oil and gas extraction. There is greater demand for older assets like FPSOs to function as tiebacks and gatherings.
Welaptega has built up an in-depth knowledge of moorings after 15 years in the subsea inspection industry. It has participated in industry JIPs and developed its own technologies to identify and quantify subsea damage caused by age-related deterioration and impact.
Halifax, Nova Scotia _ Tony Hall, CEO of Welaptega Marine, will be a featured speaker at a seminar of asset integrity experts examining the impact of ageing infrastructure in the offshore oil and gas sector.
The seminar, entitled “Insuring ageing facilities for better or worse”, is sponsored by the London-based Oil Petrochemical and Energy Risk Association (OPERA).
Participants will explore the challenges of offshore facilities being considered for subsea tie backs and gathering operations.
“We have to know that these ageing assets are still fit for purpose,” said Hall, who will speak on the topic of mooring integrity verification on offshore assets. “It’s a balance between safety, profitability and risk.”
Seminar topics include:
Other speakers include Szen Ong of BPP-Tech who will speak on Ageing Subsea Assets – Riser and Umbilical Case Studies and Judith Hackitt CBE of the UK HSE who will deliver the Keynote Address.
The day-long seminar will be held October 30, 2012 at the Swiss Re Lecture Theatre in London.
Kuala Lumpur, Malaysia, October 17, 2012 _ A new sense of urgency is emerging around ageing offshore infrastructure as facilities reach the end of their design lives and major incidents cost millions - in some cases billions, a group of integrity management experts heard during a Petronas seminar on Managing Risk on Ageing Offshore Infrastructure.
“Major incidents are leading to loss of life, environmental damage and huge costs in damage and lost production,” said guest presenter Tony Hall, CEO of mooring integrity leader Welaptega Marine. “If we don’t take care of these ageing offshore facilities, significant loss of assets is inevitable.”
Hall, whose company is world leader in risk-based integrity verification in the floating production sector, says moorings are an example of “safety critical systems” which are subject to immense environmental forces including waves, currents, abrasion and hurricanes.
