Huntington Ingalls Industries'  reports that its Newport News Shipbuilding division has successfully completed anchor testing on the aircraft carrier Gerald R. Ford (CVN 78), bringing the ship closer to its 2016 delivery to the U.S. Navy. Ford's new anchor system features a lighter anchor and chain, weighing in at half the weight of the previous Nimitz-class carriers' anchor systems. Newport News shipbuilders recently gathered to test Ford's anchor windlass system that is used to deploy and retrieve the anchor and chain.

Bill to Require Anchors, Manned Barges

The Joint Committee on Natural Resources and Agirculture of the Massachussets legislature held a hearing on a bill to require tank barges carrying petroleum products to be equipped with an anchor system, anchor chain and windlass. The bill would also require tank barges to be manned unless the Department of Environmental Protection determines other technical or operational saftey measures provide an equivalent defree of protection. The bill is similar to legislation introduced - but not enacted - in 1997.

USCG to Require Anchors, Emergency Retrieval Systems

The USCG has issued an interim rule requiring anchors and emergency retrieval systems on tank barges and the vessels towing them in coastal and Great Lakes service. In a significant change from the October 1997 notice of proposed rulemaking (NPRM), the rule requires all single-hulled tank barges operating on the U.S. territorial sea, the Great Lakes, Long Island Sound, Strait of Juan de Fuca, and parts of Puget Sound, be equipped with an operable anchor system. In addition, both single- and double-hulled tank barges and the vessels towing them must be equipped with an emergency retrieval system, such as an emergency towline or an Orville Hook. The rule also requires equipment be maintained and inspected regularly, and crewmembers be trained and drilled in its use.

Ropes manufacturer Lankhorst Ropes Offshore Division expanded its range of high performance mooring and anchoring ropes to include steel wire ropes for the offshore market. The company is now able to offer both synthetic and steel wire ropes for mooring and anchor systems, as well as towing, crane lifting, riser tensioners and drilling applications. Initially, Lankhorst will supply six-strand, eight-strand and multi strand (non-rotating) steel wire ropes direct from WireCo WorldGroup factories in Germany, U.S., Mexico, Portugal and Poland.

Mega Dock for Tug and Super Yacht Berthing

SF Marina Systems supplied a large two piece tug berth, designed for vessels up to 1,100 tons.

SF Marina Systems supplied a large two piece tug berth, designed for vessels up to 1,100 tons. The berth measures 150 x 32 ft. with a freeboard of 5 ft. The units were cast in SF Marina’s Factory in Walham Sweden, each  weighing more than 240 metric tons. The high loading of the Pier can accommodate  truck traffic, and features such as cranes, and fueling systems integrated into the design. The standard units can be shipped world wide and moored with a variety of anchoring systems with infinite lengths. The concrete structures are targeting the large tugboat and super yacht markets.

EzyRider Eco-Friendly Mooring System

The moving parts of conventional mooring systems, particularly the heavy chains, can damage seabeds which serve as vital marine habitats. With no moving parts to come in contact with the seabed floor, the EzyRider Mooring System from Global Moorings Pty Ltd has virtually no impact on the marine environment. Designed, engineered and tested to safely secure boats, even in open water conditions, EzyRider is manufactured from heavy duty, but light weight and low maintenance corrosion-resistant materials.

Massachusetts Legislature Considers Bill to Regulate Tank Barges

Massachusetts House Bill 59 (HB 59) was reported out of the Joint Committee on Natural Resources and Agriculture and referred to the Steering, Policy and Scheduling Committee. HB 59 is similar to bills introduced, but never enacted, in the 1997 and 1998 state legislative sessions. The bill requires all tank barges transporting bulk petroleum products be equipped with an operable anchor system and be manned, unless the state Department of Environmental Protection determines alternative technical or operational measures provide an equivalent degree of protection. If the bill is released by the Steering, Policy and Scheduling Committee, it can go to the floor for a third reading or for a vote. A third reading will enable individuals opposed to the bill to provide testimony to the committee.

Samson Awarded 11th Patent

Samson was awarded a patent titled Line Structure for Marine Use in Contaminated Environments. This technology was developed by Samson while partnering with Delmar Systems on its patented Omni-Max gravity-installed anchor system. Proper deployment of the new anchor design would have been hampered by the use of traditional anchor chain in this application. The additional weight of chain affects the trajectory of the anchor causing insufficient embedment into the seabed. To address this issue, Samson engineers developed a synthetic alternative that replaces the anchor chain. One of the biggest challenges in this application was protection of the synthetic rope from the damaging effects of outside contaminants it comes in contact with during use.

Partnership Sets Record for Mooring Depth

Delmar Systems, Inc. and Shell Deepwater Development, Inc. set another world record for mooring depth when the two companies partnered to moor Transocean Marianas in more than 7,500 ft. in the Gulf of Mexico. Semi-submersible drilling rig Marianas was moored in 7,569 ft. in Mississippi Canyon 657 using a Suction Anchor System and Delmar's Single Vessel Installation Procedure. The deepest anchor was set at 7,738 ft. The mooring system consists of eight 12-ft. diameter by 60 ft. long suction anchors embedded in the seafloor and attached to 10,000 ft. of 3.75 in. wire rope with the specially designed Delmar Sub Sea Connector. The connector allowed mooring line connection by an ROV provided by Oceaneering International, Inc.

BP, CSO Aker Marine Team For Unique GOM Installation

CSO Aker Marine Contractors, Inc. (CAMC), one of the Houston-based entities of the Coflexip Stena Offshore Group, announced the successful mooring of Diamond Offshore's rig the Ocean Confidence using a preset taut leg mooring with polyester rope and CAMC's SEPLA anchoring system while under contract to BP. The mooring location is in the Gulf of Mexico in 6,385 ft. (1,946 m). The project represents a significant advancement in deepwater mooring. BP, CAMC and Diamond Offshore set several Gulf of Mexico records with this project. The rig is the first MODU in the GOM to use polyester moorings on all 8 legs and the first rig to be moored employing SEPLAs on all 8 legs, a technology developed and patented by CSO Aker.

IMS introduces the deep digging Depth Master 55 (DM-55TM) as the latest addition to is dredge product line. The DM-55TM is IMS's solution to making deep maintenance dredging and environmental dredging affordable. "Over the years we have received hundreds of inquiries from ports and environmental contractors wanting to dredge deeper, but they simply could not afford to get a multi-million dollar machine and have resorted to ineffective pumps on wires and water injection vessels that don't create an even bottom profile," says IMS Division President, Jim Horton. "The DM-55TM solves this issue.
