Engineers who inspected damage at the Heritage Wharf cruise ship pier say the problems are not expected to disrupt Dockyard cruise ship schedules this year or in 2012.And the damage to the thruster wall — built at a cost of $4.1 million to shield the coastline from the thrust generated by cruise ship propellers — was believed to have been caused by wave action caused by Hurricane Igor a year ago, the report found.A summary of the findings of inspectors from an independent marine engineering firm was revealed in a statement yesterday from the Ministry of Public Works, which had ordered the assessment of structural damage at the pier.The cost of repairing the damage — and who is liable to pay for it — has not yet been worked out.“While the Ministry works to ascertain potential liabilities as well as the extent of repairs required and associated costs, it would be irresponsible to make any public statements concerning these aspects of the report,” the statement read.The engineers said the thruster wall damage poses no danger to cruise ships using the pier and will not deteriorate further under normal use.“A solution is under development that is intended to resolve the issue as a matter of priority,” the Ministry’s statement added.The specialist inspectors had examined the structure of the pier and thruster wall, the statement added, along with studying the design specifications. The report has been completed and delivered to the Ministry.Damage to the thruster wall and a warp in a catwalk used by cruise ship passengers was highlighted in a front-page story in The Royal Gazette two months ago. There was no reference to the catwalk damage in yesterday’s statement.The project to build the two-year-old Heritage Wharf was led by general contractor Correia Construction Ltd. It cost taxpayers almost $60 million, compared to the $39 million contract price. The cost overruns generated political controversy and are the subject of an investigation by Auditor General Heather Jacobs Matthews.Igor was a Category 1 storm which passed close to the Island on September 20 last year, hitting the pier with 12ft waves. According to a report by engineering firm Entech Ltd, sent to the Ministry of Transport in October last year, the cost of repairing all identified storm damage to the pier was estimated at $500,000.
