The American shipbuilding scene, filled with participants constructing all manner of vessels, has been navigating through stormy times (lately, yards along the Gulf Coast have literally been dealing with storms). The orders for newbuild, repair and conversion projects continue to flow in—albeit at a reduced pace—and the boats and ships go down the ways into the water, but the overall panorama has seen tremendous sea changes as the business has shifted.Maritime businesses worldwide have been grappling with currents both internal and external.

Maritime navigational safety near two U.S. Navy installations in Kings Bay, Ga., and Portsmouth, N.H. has been improved thanks to new Physical Oceanographic Real-Time Systems, also known as PORTS, installed by NOAA and the U.S. Navy. They are the first new PORTS in two years, and the 34th and 35th in the nationwide network.The system near Naval Submarine Base Kings Bay, the East Coast home to America’s Ohio-class submarines, is an integrated series of sensors which will provide critical real-time information on oceanographic and meteorological conditions.

LANL Releases New Sea-Ice Computer Model

Los Alamos National Laboratory (LANL) with several collaborating groups released an update for an internationally vital sea-ice computer model, called CICE version 6.0, a timely tool that supports more accurate forecasting of ice occurrence and global climate modeling.“This update improves our ability to understand a type of anchored ice, called land-fast ice, that is attached to the shore or sea bottom and can block shipping lanes and northern ports,” said Elizabeth Hunke, lead developer of the CICE model. “The polar regions are not desolate, they’re actually alive with shipping, energy development, fishing, hunting, research and military defense operations,” Hunke noted.“Sea ice makes navigation hazardous, as thick ice can block fishing boats and even makes it difficult for U.S.

Preparing for Deep Sea Command

Commanding a submarine is arguably one of the toughest jobs in the world so training for the role it is justifiably challenging, preparing those who spend their days in the deep with the skills to lead their teams. Seven prospective undersea commanding officers from the United States Navy have joined their Australian colleages on the Submarine Command Course, conducted in Australia biennially. This year it coincided with a visit by the USS Oklahoma City, a Los Angeles class attack submarine, to Fleet Base West. Shortly after arriving in Australia, the officers toured their Australian host boat for the conduct of the exercise, HMAS Farncomb, which was also berthed alongside.

Chinise Maritime Activities under US Surveillance

Nothing escapes the constant vigilance of US surveillance activities near the Chinese coast and the Pacific First Island Chain which extends from Alaska to the Philippines, according to the Beijing Morning Post. A Pathfinder-class oceanographic survey ship USNS Bowditch is in charge of operations in the Asia-Pacific. It is also part of the Special Mission Ship program established to collect intelligence over the disputed South China Sea. The USNS Bowditch is described by the Chinese as the "vacuum of ocean intelligence." It is also equipped with ocean depth multi-beam and single-beam sonar systems. With intelligence provided by the USNS Bowditch, US nuclear-powered attack submarines are capable of intercepting PLA Navy submarines in the disputed waters.

Ballast Water Treatment Modular and Just in Time

“We’re working with four independent labs right now to validate (technology) submittals ... I’m pretty optimistic we will have Coast Guard approved ballast water standards by the IMO  conference in November.”  Admiral Paul Zukunft, Commandant of the USCG, discussing the  ballast water issue at NorShipping (Photo: William Stoichevski)

A pair of market entries — one a business of powerful Japanese technology players, the other a newbie with some pedigree — reveal how bold, modular design could pay dividends in a competitive market. Their increments of innovation add up to timely ways to comply with changes, including extra U.S. Coast Guard strictures due out on the eve of an International Maritime Organization meeting in November 2015. The record numbers of vendors at Norway’s Nor-Shipping show offer paths to compliance…
