A closeup of M/V James Transport after she had been sliced.
The Canadian ship repairer Halifax In- dustries Limited, Nova Scotia, recently com- pleted its first lengthening contract.
The contract was to lengthen the 4,700- grt products tanker M/V James Transport, owned by Halco Inc. of Montreal, by insert- ing a new 40-foot-long midbody section at a cost of approximately one million (Canadian) dollars.
The job was carried out at Halifax Ship yards in the company's floating dock, Scot- iadock, and on completion provided the ves- sel with four additional cargo tanks.
After gas freeing and internal removals and disconnections, the James Transport was cut in two. The floating dock was then sub- merged enough to allow the bow section to be floated apart from the stern section. The floating dock was then raised to its normal position with the two sections 55 feet apart.
The new prefabricated 200-ton midbody section was then lifted into the dock in two sections — upper and lower — by means of
Halifax Industries' floating timberland crane.
The new section was aligned and joined to the stern section of the vessel before
Scotiadock was again flooded to allow the bow section to be floated back to the rest of the vessel.
After alignment, the two sections were welded and internal modifications completed.
The job took approximately 10 weeks to complete.
The new length of the M /"V James Trans- port is 411 feet, her breadth is 55 feet, and depth 27.5 feet.
Prefabrication of the new midbody sec- tion coincided with the completion at Hali- fax Shipyards of the yard's six-million-
Canadian-dollar steel fabrication improve- ment program, which included a new panel welding line, a new numerically controlled burning machine, and an advanced surface treatment line.

MarAd Awards $280,000 Research
Contracts On Marine Use Of Coal
The Maritime Administration (MarAd) has awarded three research contracts relating to the use of coal as a marine fuel. The total cost of the research will be $280,000.
The largest contract, for $116,000, was awarded to ECON, Inc., Princeton, N.J., and Parsons-Brinckerhoff, New York, N.Y., to investigate alternatives for providing coal bunkers in various U.S. ports. The study will evaluate factors such as the cost of capital, real estate, operations, and taxes.
Santa Fe Corp., Alexandria, Va., was awarded a $91,000 contract to analyze the maintenance and repair requirements of coal-fired steam-turbine propulsion systems.
The study is expected to cover spare parts requirements, failure rates for major com- ponents, the shipboard man-hours required for routine and preventive maintenance, and other elements affecting the in-service per- formance of these systems.
A $73,000 contract was awarded to VER-
SAR, Inc., Springfield, Va., to assess envi- ronmental factors influencing the use of coal as a marine boiler fuel. The study will ex- amine the effects of stack gas emissions and ash discharge from coal-fired ships on the environment. It will be based on a selected scenario and profile of vessels servicing ports and international trade routes.
All three studies are scheduled to be com- pleted in early 1982.
HMS Ark Royal, the Royal Navy's latest antisubmarine aircraft carrier (above) is pictured after her launch from the Swan
Hunter yard on the River Tyne in north- east England recently.
The last Invincible-class through-deck cruiser to be built, HMS Ark Royal has an expected completion date of 1985. The ship will be used as an offshore base for vertical take-off Sea Harrier fighter aircraft and
Sea King antisubmarine helicopters. It will also be a communications center from which to control surface escorts and coordinate op- erations with Royal Air Force (RAF) Nim- rocl maritime patrol aircraft.
The ship, which was launched by Her
Majesty Queen Elizabeth and the Queen
Mother, is the fifth to bear the name Ark
Royal and — at over £200 million — is the most expensive warship ever built for the
Royal Navy. It has an overall length of ap- proximately 676 feet (206 meters), beam of 105 feet (32 meters), and will accommodate over 1,000 officers and men.
