Naval Sea Systems Command completed a fleet-wide fastener study, identifying and recommending the removal of thousands of fasteners from the Navy supply system. The 16-week supply system review identified 108,000 dormant fasteners-fasteners with no contract, requisition or maintenance history in the past five years-and 3,200 duplicate fasteners where two or more identical fasteners had different stock numbers. The NAVSEA Commonality Project management team led the study, collaborating with in-service engineering agents…

BP Takes Three DH Tankers from NASSCO

Mid last month, General Dynamics divulged that its National Steel and Shipbuilding Co. (NASSCO) unit had won a lucrative and much sought after contract to build three double hull tankers for BP. The deal, worth approximately $630 million, calls for a tanker trio which will carry crude from Valdez, Alaska, to U.S. West Coast ports. The contract includes options for three additional vessels, driving the potential price-tag for the project to well more than $1 billion. The design will put strong emphasis on environmental safety, including redundant diesel-electric propulsion systems in independent engine rooms, two propellers, and twin rudders. The ship will incorporate the latest, proven technology in environmental protection, ship navigation, and cargo control systems.

Dead in the Water

The world watched as the Carnival Triumph sat still, dead in the water in the Gulf of Mexico after a main space fire caused a total loss of electrical power. For the 3,143 passengers and 1,000-plus crewmembers, there was no heat or air conditioning, toilets or sanitation, lights or  ventilation. Fortunately, despite the seriousness of the fire, which was caused by a leaking fuel line, nobody was hurt. We waited and watched for several days for tugs to arrive on the scene and begin the slow process of pulling the 893-foot ship to port to let her passengers debark and commence repairs.

ABS has published the ABS Advisory on Hybrid Electric Power Systems to help marine and offshore owners and operators make decisions about energy generation and storage. “ABS continues to lead industry safety with the first comprehensive Advisory to address the latest hybrid electric power technologies,” said ABS Chairman, President and CEO Christopher J. Wiernicki. With the increased industry focus on environmental compliance and operational performance, many owners and operators…

Control Systems on LCC 20 Saves Fuel, Reduces Workload

Naval Sea Systems Command completed the installation of new control systems aboard USS Mount Whitney (LCC 20), April 8, which will reduce fuel usage and crew workload. Engineers from the Naval Surface Warfare Center Carderock Division - Ship Systems Engineering Station (NSWCCD-SSES) SSES installed the new control systems on a number of shipboard engineering components and are specifically designed to improve automation on the optimally manned ships. “Military Sealift Command-operated ships like the Mount Whitney traditionally have lower manning levels…

Maran Takes Delivery of Electric LNG Carrier

Equipped with a GE electrical induction-based propulsion solution, the Woodside Rogers can be powered by tri-fuel engines that run on natural gas, marine diesel gas or heavy fuel oil.

The first electrical LNG carrier to be ordered by Maran Gas incorporating induction-based electric propulsion motor technology from GE’s Power Conversion business is expected to enter commercial service in July. The Woodside Rogers, built by one of the major Korean shipbuilders, Daewoo Shipbuilding & Marine Engineering (DSME), at its shipyard near Busan, successfully completed sea trials in late April and was handed over to Maran Gas on July 1. It is the first of seven LNG carriers…

Installation of Dry Flexible Coupling on USS Essex (LHD 2)

USS Essex (LHD 2)

Engineers at the Naval Ship Systems Engineering Station (NAVSSES), Naval Surface Warfare Center Carderock Division in Philadelphia recently oversaw the installation of dry flexible couplings on the lube oil service pumps and main feed pumps on USS Essex (LHD 2). The new couplings replace grease-lubricated versions eliminating hazardous waste and quarterly maintenance requirements for Sailors. The new couplings will run for a year on Essex before moving forward with installation on other amphibious ships.

MetalCraft Unveils First Electric Powered Patrol Boat

Patrol Boat-1 is really the first, the first ever electric powered patrol boat. MetalCraft Marine designed and built the boat for the City of Annapolis’ Harbormaster. The boat utilizes a Steyr hybrid diesel/electric engine that permits either electric power or for higher speeds, diesel power. The propulsor is a Hamilton 274 waterjet. The jet can propel the boat in electric patrol mode at 4.5 knots, as it approaches and checks boats in the harbor ensuring anchoring permits are valid.

BP Orders Fourth Tanker

BP has placed an order for a fourth double-hull oil tanker for use in delivering Alaska North Slope crude oil to refineries on the west coast. BP placed orders for three tankers in September 2000. Construction of the 1.3-million-barrel-capacity tankers will begin in early 2002. National Steel and Shipbuilding Co. (NASSCO) of San Diego is scheduled to deliver the first ship in late 2003 with subsequent ships being delivered in 2004, 2005 and 2006. BP will complete conversion of its Alaska fleet to double hulls in 2006. The four-ship order, with options for two additional tankers, has been matched to BP?s Alaskan production plans for the next decade.

ABS: New Guidance on Energy Storage

ABS has published The ABS Guide for Use of Supercapacitors in the Marine and Offshore Industries (Supercapacitor Guide) to support safe application of hybrid power in the marine and offshore industries. The maritime industry is increasingly interested in using supercapacitors as an energy storage solution when quick energy delivery is required during a peak loading condition. Particularly, offshore supply vessel (OSV) owners are considering supercapacitors to supplement energy supply during high-load operations, such as using power thrusters for dynamic positioning while station keeping. "We are developing a series of guides on energy storage systems so our clients have as many options as possible to effectively manage energy use…
