DREDGING UP AFFORDABLE PRECISION

摘要

Not all dredging operations require high precision, but to support the construction of offshore pipelines-like those connecting oil and gas platforms to onshore facilities-the final leg requires centimeter precision. And achieving that accuracy often comes at a time-consuming and costly price. Singapore-based Offshore Construction Specialists (OCS) understands well the challenge in providing consistent high precision in offshore environments, particularly when they're closer to shore. "For pipeline installation, near-shore construction needs more attention than when you are laying pipe, for instance, 100 kilometers away from land," says Keith Jackson, managing and technical director for OCS. "In near-shore construction you are concerned about fishing vessels, recreational folks, and other ship traffic-those might damage a pipeline-so you need to bury it. We need to dredge the seabed down, lay the pipe into the trench and backfill."
