Construction of Ship Building Facilities Using Target:Pile

Atkinson Construction used two Target:Pile Systems to aid in the placement more than 3,000 marine piles and 100 caisson structures. Both systems utilize Trimble's RTK receivers to position the barges with centimeter level accuracy. The first stage of the project, at Bath Iron Works Land-Level Transfer Facility Project, Bath, Maine, required the accurate placment of metal templates, which will be used to position five caissons at a time. The template was welded onto the side of the barge, and the center of the first caisson within the template was loaded into the Target:Pile system. Using the position of the first caisson and the required heading of the template, the barge could be moved into location. Once on location the template was spudded onto the seabed and detached from the barge.

CAPE Holland Deploys Lifting Tool for Pile Installation

Earlier this month the CV-320 upending Vibro Lifting Tool (VLT-U) with was used for installation of 13 piles at the Kanaaldok B3 in Antwerpen.   These piles will be used to build a jetty to serve as a temporary mooring place. The piles, 35 meters long and 2.9 meters in diameter, were picked up, lifted upright and  stabbed and driven as deep as possible, only using the CV-320 VLT-U. All 13 were in position in record time of just 4 days. After all piles were installed they were driven to final penetration with a 500 kJ Impact Hammer. The harbor location gave the perfect opportunity for invited contractors and their clients to witness the upending and stabbing capabilities of the Vibro Lifting tool in the comfort of a warm vessel.

Project Profile, Muuga Port

In very challenging weather conditions Danish contractor Per Aarsleff is installing its largest profile and one of its longest combination steel pile retaining walls for the extension to the container terminal in the Port of Muuga on the Gulf of Finland south coast, 17km east of the Estonian capital Tallinn. The site team, with its fleet of specialist marine plant, has been coping with freezing temperatures, strong winds and rough seas at the exposed site to accurately drive over 420 tubular steel piles up to 1.67m diameter and 45m long into the seabed.

New Approaches to Inland Infrastructure Renewal

A new engineered repair system for seawalls is based on fiber reinforced polymer (FRP) technology that has been used for several years to repair and strengthen worn and damaged marine piles made of timber or concrete using specialized composites. Pictured here are worn bridge piles being wrapped with FRP laminates in St. Louis

Economical repairs are being applied to rapidly corroding steel and concrete structures in U.S. ports and inland waterways. The new repair systems – PileMedic & SPiRe – might just be what the doctor ordered. Recent advancements in using Fiber Reinforced Polymer (FRP) for major structural repair and strengthening of submerged marine piles made of concrete or even timber has led to an economical, less invasive infrastructure repair solution for inland port development compared to current systems.

Port of Galveston to Repair Public Pier

Galveston Wharves’ board of trustees today unanimously approved a project to repair pilings and pier deck in the Pier 19 area of the port. The board awarded the contract, with a not to exceed value of $190,000, to Taylor Marine Construction, Inc. to replace damaged pilings and deck. The work, which is expected to last approximately three months, is scheduled to begin in February 2015. Pursuant to the Charter of the City of Galveston, the port is charged with maintaining the Pier 19 public facility. The contract awarded today is one of two current projects. Last month, Texas Gulf Construction Company, Inc was awarded a $120,000 contract to rebuild the pier that connects the fuel pier to shore. On October 25, 2014 a section of the wooden pier that provides access to the fuel dock collapsed.

Furgo’s New Offshore Wind Farm Drill Readies for Action

The new T120 drill on top of the Conductor (framework that lifts it above the waves) all in yellow, and also showing the down hole equipment in blue. It will be configured as shown here and attached to the orange steel frame which is fixed to the deck of the transport installation vessel (TIV).

Specialist overwater drilling and marine construction contractor Fugro Seacore is building a pile top drill, the T120, for the offshore wind farm market to assist with monopole installations of up to eight meters diameter. Their current big drill has 90 metric tons of rotational torque; the new one will have 120 metric tons. This new addition to the fleet means they will have two drills capable of relief drilling piles of larger than six-meter diameter simultaneously, for instances where larger monopiles are the chosen foundation for the wind farm sites of Round three in U.K.

Construction work has begun on the United States Merchant Marine Academy's new Mallory Pier. Construction crews from Russell Marine have had a barge on-site in Hague Basin since early January focused on the first phase of the project, which required preparing the old pier to help support the new construction. Last week the first pre-cast concrete piles arrived by barge, and after much anticipation, the first test pile of the new pier was driven into the Long Island Sound seabed. Seven more test piles will be driven in the seabed this week and measurements of their holding capacity taken.
