Transportation cradles are a key component in the build, transportation and launch of a ship and a suitable design can be fundamental in the success of these operations. Throughout their use they will support the various blocks and completed ship during construction, act as the interface between the vessel and SPMT’s (Self Propelled Modular Transporters) or barge, and ultimately support the ship during float off operations. The cradles are possibly the only item of equipment that will see the ship from very early stages of construction through until she is floating in the water.

Value of Fire-damaged Vessel Disputed

Press release - International Transport Intermediaries Club (ITIC) has reported a case in which hull and machinery insurance underwriters instituted proceedings against a marine consultancy firm for alleged negligence in failing to properly review shipyard quotes in respect of the cost of repairing a fire-damaged vessel. The insured vessel had suffered extensive fire damage. The owners claimed that the ship was a Constructive Total Loss (CTL), alleging that the cost of repairing it was in excess of its insured value. The insurers rejected this claim, maintaining that the vessel was capable of economic repair. The vessel was ultimately scrapped, and the only remaining dispute was over the amount which the insurers were obliged to pay under the policy.

Salvage Update on Rena Wreck Removal

Salvors, Resolve Salvage & Fire report a highly productive past week. The past seven days has been highly productive for Resolve Salvage & Fire - wreck reduction has progressed through the removal of 85 individual pieces of steel, with the total steel weight removed now 300 tonnes. The reduction has mainly occurred in the forecastle deck area. Joseph Farrell III, Resolve’s Naval Architect who manages all day-to-day operations on board the Rena, says “progress is particularly encouraging considering the challenging weather that has prevented work for one and a half full days over the past week”. Maritime New Zealand officials have visited the wreck to see how work is progressing and review safety arrangements.

Arctic Route Helps Owners Slash Fuel Costs

“I think it important to remind everyone that the place is ice-covered – fully or partially – eight to 10 months out of the year through the century and beyond," Said Lawson W. Brigham, PhD, Distinguished Professor, Geography and Arctic Policy, University of Alaska – Fairbanks.

The debate regarding working in and around the Arctic is multi-tiered, with environmental, technical and emergency response heading the list. There is no debate regarding the fuel, money and emissions to be saved by shortening select global shipping routes. In a report from Bloomberg news posted June 13 on http://www.businessweek.com, it was said there will be a rise in dry bulk cargos hauled through Arctic waters this season, a journey that can halve shipping time compared to some Suez Canal shipments, and simultaneously reduce fuel consumption, costs and emissions.

The Arctic: Economic Promise or Environmental Peril?

 “There are between 40-160B barrels of ‘technically recoverable’ conventional oil North of the Arctic Circle; most offshore & most in less than 500m of water.”  Dr. Donald Gautier, U.S. Geological Survey

The fervor to move shipping routes and energy business north of the Arctic Circle is palpable, as countries with physical connection and even ‘non-Arctic’ states are making moves and plans to stake claims to the vast potential that lies within. While the maritime and subsea technology allowing ops in the Arctic’s harsh environs has moved forward fast, there are repeated and regular ‘warning shots across the bow’ of budding entrepreneurs large and small, as the Arctic environment is still largely undeveloped territory, representing risky operations for even the heartiest of souls.

Judicial Decision on M/V Mokihana Rebuild

On December 4, 2009, a federal district court in Va. entered judgment in favor of the U.S. Coast Guard and Matson Navigation Company, Inc. in a long-running vessel foreign rebuild case. Winston & Strawn LLP represented Matson. The Shipbuilders Council of America, Inc. and Pasha Hawaii Transport Lines LLC sued the Coast Guard initially in November 2006 seeking to disqualify the M/V Mokihana from the U.S. coastwise trade because of work to be done to the vessel in China. That initial suit was dismissed in 2007, but then re-initiated on December 10, 2007 after the work on the M/V Mokihana was complete. The M/V Mokihana, a container ship, had work done in China to prepare the vessel for the addition of a roll-on/roll-off garage added to the stern of the vessel in Alabama.

Investment in Design: Oil Tankers The Rules are About to Change

A seminal approach to class following the landmark decision by three of the classification societies two years ago to develop common edicts governing oil tanker hull structures, a complete draft set of new, unified rules is to be circulated for industry comment in June 2004. Drawn up by American Bureau of Shipping, Det Norske Veritas, and Lloyds Register, the new rulebook is expected to be published next January, and to be brought to bear on all oil tankers of 150-m length and over ordered from July 1, 2005 onwards. The rationale behind the project for a single set of rules governing tanker scantlings was to eliminate possible competition on structural requirements and standards.

Harland & Wolff Rescued

Harland & Wolff's (H&W) existence was extended last week as it won a 300 million pound ($458 million) contract to build four passenger ferries. The order from Bahamas-based Seamasters International Inc. includes an option for two additional ships. If the full order is taken, the six ships should provide work for the yard through 2004. The order came just a day after Harland & Wolff workers accepted a three-year pay deal, a deal which was equally crucial in ensuring the company's near-term future. Harbinson estimated the order for the RoRo ferries would secure around 1,000 of the 1,300 core jobs at the shipyard. The yard, whose giant yellow cranes dubbed "Samson and Goliath" dominate the Belfast skyline, is still a mainstay of the British-ruled province's economy.
